A survey of helminth parasites of cats from Saskatoon. (1/335)

In a survey of 52 cats from the Saskatoon area, Ollulanus tricuspis were found in 2 animals with burdens of 2308 and 533, respectively. Small burdens of the following helminths were also found: Physaloptera spp., Toxocara cati, Taenia spp., Dipylidium caninum, and Ancylostoma sp.  (+info)

Infections by helminth parasites in "puyenes", Galaxias maculatus (Galaxiidae, Salmoniformes), from Southern Argentina with special reference to Tylodelphys barilochensis (Digenea, Platyhelminthes). (2/335)

The occurrence of Tylodelphys barilochensis, Acanthostomoides apophalliformis, Contracaecum sp. and Camallanus corderoi infecting Galaxias maculatus ("puyenes") was quantified for the first time in Lake Nahuel Huapi, southern Argentina. T. barilochensis was recorded in this lake for the first time. The role of G. maculatus population in transmission of parasites to the salmonids is more important for Contracaecum sp. (prevalence 14-34%) and A. apophalliformis (prevalence 30-54%) than for C. corderoi (prevalence 6-8%). The absence of Diphyllobothrium spp. in samples shows that the G. maculatus population does not play any role in the life cycles of these important zoonotic parasites. The sex of the host had no effect on T. barilochensis abundance. Statistical differences in T. barilochensis abundance between "puyenes" of the same size class between sampling stations and positive correlation between prevalence of infected snails and T. barilochensis abundance in fish suggest that different stocks have been sampled. Factors influencing T. barilochensis abundance are discussed.  (+info)

A trade-off between energy intake and exposure to parasites in oystercatchers feeding on a bivalve mollusc. (3/335)

Models of animal dispersion between habitat patches that differ in resource density assume that animals maximize their fitness by maximizing the rate at which they consume resources. How valid is this assumption? Studies on wading birds have been central to the application of dispersion models to predator-prey systems. However, these birds do not always attempt to maximize their rate of energy intake, implying that maximization involves costs as well as benefits. Overwintering oystercatchers feeding on cockles in the Burry Inlet, South Wales, do not consume the larger more energetically profitable cockles even though consuming these prey would increase their rate of energy intake. This paper tests the hypothesis that maximizing energy intake involves a trade-off with exposure to helminth parasites. Cockles are important intermediate hosts for helminth parasites, for which oystercatchers are the definitive host. The helminth intensity of cockles increased significantly with cockle size. A functional response model was used to examine how size selection by the birds influenced energy intake and the ingestion rate of parasites. To maximize energy intake birds should selectively consume the larger size classes, but to minimize the ingestion rate of parasites they should consume the smallest size classes. In the wild, birds selectively consumed intermediate size classes, which could represent a compromise between these conflicting demands. The implications for animal dispersion models are discussed.  (+info)

Parasitological survey on wild carnivora in north-western Tohoku, Japan. (4/335)

In the winter of 1997-1998, we collected parasitological data from 60 wild carnivora in the north-western part of Tohoku region, Japan. These included 7 foxes (Vulpes vulpes japonica), 20 raccoon dogs (Nyctereutes procyonoides viverrinus), 29 martens (Martes melampus melampus), 3 weasels (two Mustela sibirica itatsi and one M. nivalis namiyei), and one Japanese badger (Meles meles anakuma). Roundworms (Toxocara canis in foxes and Toxocara tanuki in raccoon dogs), hookworms (Ancylostoma kusimaense and Arthrostoma miyazakiense) and Molineus sp. in the small intestine were the most prevalent in foxes and raccoon dogs. In martens, Aonchotheca putorii in the stomach, Concinnum ten in the pancreatic duct, Molineus sp. and Euryhelmis costaricensis in the small intestine were the most prevalent. Collected parasites include some new helminth species for this region or Japan; the strobilar stage of Taenia polyacantha from foxes, Pygidliopsis summa from a raccoon dog, Eucoleus aerophilus, A. putorii, and Soholiphyme baturini from martens.  (+info)

Helminth fauna of carnivores distributed in north-western Tohoku, Japan, with special reference to Mesocestoides paucitesticulus and Brachylaima tokudai. (5/335)

In the winter of 1998-1999, we collected parasitological data from 54 wild carnivores in the north-western part of Tohoku region, Japan. These consisted of 38 martens (Martes melampus melampus), 14 raccoon dogs (Nyctereutes procyonoides viverrinus) and 2 foxes (Vulpes vulpes japonica). Collected helminth parasites were 11 nematode, 10 trematode, 3 cestode, and a single acanthocephalan species, including 5 hitherto unknown species for this research area or the mainland of Japan (Honshu). Mesocestoides paucitesticulus was for the first time recorded from martens as well as from carnivores distributed in Honshu. Brachylaima tokudai originally recorded from Urotrichus talpoides in the central part of Honshu was for the first time found from a raccoon dog.  (+info)

Helminthic transmission and isolation of Ehrlichia risticii, the causative agent of Potomac horse fever, by using trematode stages from freshwater stream snails. (6/335)

We report successful helminthic transmission of Ehrlichia risticii, the causative agent of Potomac horse fever, using trematode stages collected from Juga yrekaensis snails. The ehrlichial agent was isolated from the blood of experimentally infected horses by culture in murine monocytic cells and identified as E. risticii ultrastructurally and by characterization of three different genes.  (+info)

Drug resistance in human helminths: current situation and lessons from livestock. (7/335)

In this review the available reports on drug resistance in human helminths, particularly hookworms and schistosomes, are critically analyzed. The experiences with helminths of livestock are then reviewed, in particular the factors contributing to the development of anthelmintic resistance, the mechanisms and genetics of resistance to various anthelmintic classes, and the methods available for detection. These experiences appear to be worryingly similar and relevant to the potential development of drug resistance in human helminths. Recommendations to reduce its risks are suggested.  (+info)

Evaluation of commercially available preservatives for laboratory detection of helminths and protozoa in human fecal specimens. (8/335)

Formalin and mercuric chloride-based low-viscosity polyvinyl alcohol (LV-PVA) are widely used by most diagnostic parasitology laboratories for preservation of helminth eggs and protozoan cysts and trophozoites in fecal specimens. Concerns about the toxicity of formalin and the difficulty of disposal of LV-PVA are powerful incentives to use alternate preservatives. Such alternatives have been marketed by several companies and are often presented as one-vial, non-mercuric chloride fixatives that aim at performing the same role as formalin and PVA combined. We compared five, one-vial commercial preservatives, two from Meridian Diagnostics, Inc. (Ecofix and sodium acetate-acetic acid-formalin), and one each from Scientific Device Laboratories, Inc. (Parasafe), Alpha Tec Systems, Inc. (Proto-fix), and Streck Laboratories, Inc. (STF), with 10% formalin and LV-PVA. Fecal specimens obtained from patients in a Brazilian hospital were aliquoted within 12 h of collection into the seven preservatives mentioned above and were processed after 1 month at the Centers for Disease Control and Prevention. Direct and concentrated permanent smears as well as concentrates for 20 positive specimens (a total of 259 processed samples) were prepared, stained according to the manufacturers' instructions, examined, and graded. Positive specimens contained one or more parasites with stages consisting of eggs, larvae, cysts, and a few trophozoites of Giardia intestinalis. Criteria for assessment of the preservatives included the quality of the diagnostic characteristics of helminth eggs, protozoan cysts, and trophozoites, ease of use, and cost. Acceptable alternatives to formalin for wet preparations were found. Ecofix was found to be comparable to the traditional "gold standard" LV-PVA for the visualization of protozoa in permanent stained smears. This study suggests that more acceptable alternatives to the traditional formalin and LV-PVA exist.  (+info)

Kato-Katz is a widely used method for the diagnosis of soil-transmitted helminth infection. Fecal samples cannot be preserved, and hence, should be processed on the day of collection and examined under a microscope within 60 min of slide preparation. Mini-FLOTAC is a technique that allows examining fixed fecal samples. We assessed the performance of Mini-FLOTAC using formalin-fixed stool samples compared to Kato-Katz and determined the dynamics of prevalence and intensity estimates of soil-transmitted helminth infection over a 31-day time period.; The study was carried out in late 2013 on Pemba Island, Tanzania. Forty-one children were enrolled and stool samples were subjected on the day of collection to a single Kato-Katz thick smear and Mini-FLOTAC examination; 12 aliquots of stool were fixed in 5% formalin and subsequently examined by Mini-FLOTAC up to 31 days after collection.; The combined results from Kato-Katz and Mini-FLOTAC revealed that 100% of children were positive for Trichuris ...
LONDON - Chronic diarrhoea could be treated using parasitic worms, according to a new study.. Researchers from the New York University Langone Medical Center in a study of monkeys found that the treatment restores gut bacteria to a healthy state. Other work in mice has already suggested conditions such as ulcerative colitis could be treated in this way, the BBC News reported. Inflammatory bowel diseases, like colitis, are often fuelled by a wrongly targeted response by the immune system to gut bacteria.. Such diseases are more common in developed countries and scientists suggest this is because people in developing countries have more exposure to parasitic worm (helminth) infections and therefore have a natural protection that has evolved as people and worms learnt to co-exist. Recent studies have used parasitic worms to successfully treat inflammatory bowel disease in humans, but it is unclear exactly how they do this. The latest study looked at monkeys because young macaques kept in captivity ...
TY - JOUR. T1 - Synthetic analogues of the parasitic worm product ES-62 reduce disease development in in vivo models of lung fibrosis. AU - Suckling, Colin J.. AU - Mukherjee, Sambuddho.

Y1 - 2018/9/1. N2 - Parasitic worms are receiving much attention as a potential new therapeutic approach to treating autoimmune and allergic conditions but concerns remain regarding their safety. As an alternative strategy, we have focused on the use of defined parasitic worm products and recently taken this one step further by designing drug-like small molecule analogues of one such product, ES-62, which is anti-inflammatory by virtue of covalently attached phosphorylcholine moieties. Previously, we have shown that ES-62 mimics are efficacious in protecting against disease in mouse models of rheumatoid arthritis, systemic ...
Helminths (/ˈhɛlmɪnθs/), also commonly known as parasitic worms, are large multicellular organisms, which when mature can generally be seen with the naked eye. They are often referred to as intestinal worms even though not all helminths reside in the intestines; for example schistosomes are not intestinal worms, but rather reside in blood vessels.. There is no clear consensus on the taxonomy of helminths; it is more of a commonly used term to describe certain worms with superficial similarities. These are flatworms (platyhelminthes), namely cestodes (tapeworms) and trematodes (flukes), and roundworms or nemathelminths (nematodes) - both of these are parasitic worm types - and the annelida, which are not parasitic or at the most ectoparasites like the leeches.[1]. Many, but not all, of the worms referred to as helminths belong to the group of intestinal parasites. An infection by a helminth is known as helminthiasis, soil-transmitted helminthiasis, helminth infection or intestinal worm ...
The geographic distribution of helminth infection and tuberculosis (TB) overlap substantially. Experimental animal models and limited data from humans have shown that intestinal helminths could subvert the host immune response towards a T-helper 2 (Th2)-type immune response and an increased regulatory T-cell activity (Tregs). This in turn affects the hosts ability to mount an effective Th1 immune-mediated protection against Mycobacterium tuberculosis. However, evidence for this hypothesis in the human setting from helminth infected TB patients is limited. This thesis primarily focuses on the immunological and clinical impact of helminth infection on pulmonary TB. The kinetics of the Quantiferon-Gold (QFN) assay, which measures IFN-³ response to TB-specific antigens in whole blood was assessed and showed a modest decline during TB treatment to the level observed for healthy blood donors. We further assessed another clinical monitoring tool, the-TB-score, composed of clinical signs and symptoms ...
(Medical Xpress)-Doctor Joel Weinstock, a parasitologist at Tufts Medical Center in a commentary piece published in the journal Nature, describes work that he and colleagues have been involved in that focuses on studying the possibility of introducing parasitic worms into the guts of patients suffering from autoimmune diseases such as Crohns disease. The thinking he says, is that modern hygienic lifestyles may be contributing to such diseases and that reintroducing parasitic worms and perhaps certain bacteria into the gut may restore a natural balance in the gut and relieve patients of such symptoms as chronic diarrhea, bleeding and infections.
Despite the high prevalence of helminth infections among preschool-aged children, control programs in sub-Saharan countries primarily focus on school-aged populations. We assessed the prevalence of helminth infections and determined risk factors for infection among preschool-aged children in the urban setting of Dar es Salaam, Tanzania.; Starting in October 2015, we conducted a 12-month prospective study among tuberculosis (TB)-exposed children under the age of 5 years and unexposed controls from neighboring households. At the time of recruitment, we collected medical histories, assessed development and cognitive functions, and performed medical examinations. We performed full blood cell counts and screened for HIV and malaria. Point-of-care circulating cathodic antigen (POC-CCA), urine filtration, Kato-Katz, FLOTAC, and Baermann tests were employed to detect helminth infections in urine and stool. Helminth infections were stratified for Schistosoma and other helminths to identify risk factors, ...
Abstract Intestinal parasites are important contributors to global morbidity and mortality and are the second most common cause of outpatient morbidity in Ethiopia. This cross-sectional survey describes the prevalence of soil-transmitted helminths and intestinal protozoa in preschool children 0-5 years of age in seven communities in the Amhara region of Ethiopia, and investigates associations between infection, household water and sanitation characteristics, and child growth. Stool samples were collected from children 0-5 years of age, 1 g of sample was preserved in sodium acetate-acetic acid-formalin, and examined for intestinal helminth eggs and protozoa cysts ether-concentration method. A total of 212 samples were collected from 255 randomly selected children. The prevalence of Ascaris lumbricoides, Trichuris trichiura, and hookworm were 10.8% (95% confidence interval [CI] 6.6-15.1), 1.4% (95% CI = 0-3.0), and 0% (95% CI = 0-1.7), respectively. The prevalence of the pathogenic intestinal protozoa
Looking to treat a parasitic worm infection during pregnancy? Heres how to avoid and treat parasitic infections like tapeworms.
Short courses of most other antibiotics will typically only cause a temporary loss of benefit for between 2 and 8 weeks (e.g., ➿ erythromycin [55]), although it is possible for efficacy to be reduced for longer, e.g., 4 months, and even 6 months, and there is anecdotal evidence suggesting a correlation between the length of a course of antibiotics and the length of time that affected helminths are out of action. This might suggest that a single shot of antibiotic might have little or no effect on human helminths, as has been reported by one hookworm host, [56] but the type of antibiotic used may be critical in this case, and some antibiotic drugs might adversely affect a helminth colony even when only a single injection is administered. This happened when one hookworm host was given a single, 1 gram shot of cefazolin. See Cefazolin for details. It is possible that even a small dose of antibiotic could cause a return of symptoms in some people. For example, one hookworm host has reported ...
An infection with helminth parasites poses a substantial challenge towards the mammalian disease fighting capability. of Notch pathway modulators to take care of helminth allergies and infections. The multi-faceted systems of Type 2 immune system activation Multicellular eukaryotic helminth parasites afflict more than a billion human beings world-wide [1,2]. Soil-transmitted intestinal helminths, including and types, water-borne trematodes, and filarial parasites such as for example infection (schistosomiasis), where transit of parasite eggs through tissue causes harm, fibrosis, vascular redecorating and organ dysfunction [16]. This potential for severe damage demands that sponsor tissue-protective gene manifestation changes be quick, broad-sweeping and highly organized. Notch-mediated modulation of global gene manifestation programs is definitely consequently a potentially effective mechanism to elicit such changes [17]. Also, Notch-mediated cell-cell signals allow for quick alteration of gene ...
Identifying methods to slow disease progression in patients with HIV-1 infection remains a top priority in many regions of the world. In many countries, medications known to slow progression are not readily affordable or available. Many of the individuals living in these countries are also co-infected with a variety of other diseases such as tuberculosis, malaria and soil-transmitted helminths. There are data to suggest that infection with these agents may activate the immune system in HIV-1 co-infected individuals and may lead to more rapid HIV disease progression. This study will evaluate the potential impact of treating helminths in HIV-1 seropositive individuals. Markers of disease progression and immune activation will be assessed. We will also measure the amount of virus in genital secretions to determine if treatment of co-infection can reduce the infectiousness of HIV in these individuals ...

In the developing world hundreds of millions of people suffer from intestinal parasitic worms (helminths) and intestinal protozoon infections (e.g. amoebiasis). These are often referred to neglected tropical diseases. This worm like organisms feed on their host, taking the nutrition and causing weakness and disease. More than 1 billion people are infected with soil-transmitted helminths, schistosomes and intestinal protozoa and the annual global burden might be as high as that owing to malaria or tuberculosis. This can cause undernourishment, dysentery (infection of the intestines) and diarrhea. It has been shown that parasitic infections in childhood can interfere with cognitive development (mental) and can have negative effects in adulthood. The global strategy to control helminthiasis is preventive chemotherapy, which is the regular administration of anthelminthic drugs (medication that works to treat parasitic worms) to at-risk populations. However, re-infection can occur due to unclear ...

Helminths, including nematodes, cestodes and trematodes, are complex parasitic organisms that infect at least one billion people globally living in extreme poverty. Helminthic infections are associated with severe morbidity particularly in young children who often harbor the highest burden of disease. While each helminth species completes a distinct life cycle within the host, several helminths incite significant lung disease. This impact on the lungs occurs either directly from larval migration and host immune activation or indirectly from a systemic inflammatory immune response. The impact of helminths on the pulmonary immune response involves a sophisticated orchestration and activation of the host innate and adaptive immune cells. The consequences of activating pulmonary host immune responses are variable with several helminthic infections leading to severe, pulmonary compromise while others providing immune tolerance and protection against the development of pulmonary diseases.

INTRODUCTION. The estimated poultry census in the world is 14.718 billion and 75 % of this population is found in developing countries6, where they are commonly kept as free-range chickens9. Rural free-range chickens provide eggs and meat which are important sources of protein1 and also serve as a source of income13.. Productivity of free-range chickens is generally low and mortality is high5.. Causes of high mortality and low productivity include lack of proper management, lack of adequate nutrition, diseases and predation6. Lack of adequate nutrition and proper management force the free-range chickens to scavenge for food in contaminated environments, which predisposes them to arthropod-borne helminth infections7.. Helminth parasites of free-range chickens have been reported to occur at a high prevalence in several developing countries1,7,8,10,12,13. To our knowledge there are no reports on the prevalence of gastrointestinal helminths of free-range chickens from rural and peri-urban ...
Helminth infections of cattle affect productivity in all classes of stock, and are amongst the most important production-limiting diseases of grazing ruminants. Over the last decade, there has been a shift in focus in the diagnosis of these infections from merely detecting presence/absence of infection towards detecting its impact on production. This has been facilitated by studies observing consistent negative correlations between helminth diagnostic test results and measures of productivity. Veterinarians are increasingly challenged to consider the economic aspects of their work, and the use of these tests should now be integrated in economic evaluation frameworks for improved decision making. In this paper, we review recent insights in the farm-specific economic impact of helminth infections on dairy cattle farms as well as in farmer attitudes and behaviour regarding helminth control. Combining better economic impact assessments of helminth infections together with a deeper understanding of the non
Abstract Background The convergent distribution of the Human Immunodeficiency Virus (HIV) and helminth infections has led to the suggestion that infection with helminths exacerbates the HIV epidemic in developing countries. In South Africa, it is estimated that 57% of the population lives in poverty and carries the highest burden of both HIV and helmith infections, however, the disease interactions are under-researched. Methods We employed both coproscopy and Ascaris lumbricoides-specific serum IgE to increase diagnostic sensitivity and to distinguish between different helminth infection phenotypes and their effects on immune responses in HIV co-infected individuals. Coproscopy was done by formol ether and Kato Katz methods. HIV positive and negative adults were stratified according to the presence or absence of A. lumbricoides and/or Trichuris trichuria eggs with or without elevated Ascaris IgE. Lymphocyte subsets were phenotyped by flow cytometry. Viral loads, serum total IgE and eosinophils ...

Funding agencies are dedicating substantial resources to tackle helminth infections. Reliable maps of the distribution of helminth infection can assist these efforts by targeting control resources to areas of greatest need. The ability to define the distribution of infection at regional, national and subnational levels has been enhanced greatly by the increased availability of good quality survey data and the use of model-based geostatistics (MBG), enabling spatial prediction in unsampled locations. A major advantage of MBG risk mapping approaches is that they provide a flexible statistical platform for handling and representing different sources of uncertainty, providing plausible and robust information on the spatial distribution of infections to inform the design and implementation of control programmes. Focussing on schistosomiasis and soil-transmitted helminthiasis, with additional examples for lymphatic filariasis and onchocerciasis, we review the progress made to date with the application of MBG

One third of the worlds population is infected with Mycobacterium tuberculosis (Mtb), the causative agent of tuberculosis (TB). While the majority of Mtb-infected individuals are asymptomatic with the latent disease, millions of people present with active disease, which is one of the leading causes of death worldwide. In areas where parasitic helminth worms are endemic, the incidence of active TB is relatively high, suggesting that helminth infection exacerbates TB. Leticia Monin and colleagues at the Washington University School of Medicine used a mouse Mtb infection model to explore the relationship between helminth co-infection and Mtb manifestations. Co-infection with Schistosoma mansoni promoted fibrosis, increaed inflammation, and resulted in accumulation of arginase-1-expressing macrophages, which formed type 2 granulomas, in the lungs of in Mtb-infected mice. Treatment of co-infected animals with anti-helminth agents reduced S.mansoni burden, ameliorated inflammation, improved ...

Repeated roundworm infestation in Sheltie Question: Dr. Micheal Richards, Our Sheltie who is 1 1/2 years old has had Roundworms so many times we keep roundworming him , and making sure he get 2 doses of Roundworm meds in a 2 week period,but nothing seems to be getting rid of these Roundworms completely. He was dewormed 3 times as a young puppie than at 7 months old he had Roundworms so bad he was vomiting them.It was terrible our Pokie got so sick. Out Vet gave us Drontal Plus and we used it on both our Shelties to make sure they both got rid of them.We used it twice 2 weeks apart.Although our Older Sheltie has never shown any signs of roundworms nor did we see any in his fecals.But we did see many in Pokie our youngest Sheltie. But after the 2nd Worming we saw no more. Than about 3 months later I decided on my own to give Pokie Nemex 2 as he was coughing the same way when he had Roundworms before.Sure enough he had Roundworms again so on to the 2nd Dose again.

The geographic distribution of helminth infection and tuberculosis (TB) overlap substantially. Experimental animal models and limited data from humans have shown that intestinal helminths could subvert the host immune response towards a T-helper 2 (Th2)-type immune response and an increased regulatory T-cell activity (Tregs). This in turn affects the hosts ability to mount an effective Th1 immune-mediated protection against Mycobacterium tuberculosis. However, evidence for this hypothesis in the human setting from helminth infected TB patients is limited. This thesis primarily focuses on the immunological and clinical impact of helminth infection on pulmonary TB. The kinetics of the Quantiferon-Gold (QFN) assay, which measures IFN-³ response to TB-specific antigens in whole blood was assessed and showed a modest decline during TB treatment to the level observed for healthy blood donors. We further assessed another clinical monitoring tool, the-TB-score, composed of clinical signs and symptoms ...

Intestinal worms have an incredibly bad reputation. The thought of them sneaking around inside our bodies and eating us from the inside is pretty unpleasant. But just 100 years ago, before toilets and running water were commonplace, everybody had regular exposure to intestinal worms. Thanks in part to modern plumbing, people in the industrialized world have now lost almost all of their worms, with the exception of occasional pinworms in some children.. Intestinal worms are properly called helminths, which most dictionaries will tell you are parasites. Exploiting their hosts, draining resources, sucking the life out of the body - thats what parasites do, by definition. Indeed, many helminths, including the porcine tapeworm and the human hookworm, are known to cause disease and even death in the human population. Parasitic worms are still a big problem in some parts of the world.. But for decades, results coming out of lab after lab have shown that some kinds of helminths can be extremely ...
BACKGROUND: Reliable and updated maps of helminth (worm) infection distributions are essential to target control strategies to those populations in greatest need. Although many surveys have been conducted in endemic countries, the data are rarely available in a form that is accessible to policy makers and the managers of public health programmes. This is especially true in sub-Saharan Africa, where empirical data are seldom in the public domain. In an attempt to address the paucity of geographical information on helminth risk, this article describes the development of an updated global atlas of human helminth infection, showing the example of East Africa. METHODS: Empirical, cross-sectional estimates of infection prevalence conducted since 1980 were identified using electronic and manual search strategies of published and unpublished sources. A number of inclusion criteria were imposed for identified information, which was extracted into a standardized database. Details of survey population, ...

Lead researcher, Dr Aaron Jex, Faculty of Veterinary Science, said, We know that humans infected with the harmless, pig whipworm can have significantly reduced symptoms linked to autoimmune diseases. And now we have the genetic sequence of the worm, it opens the door to future human drug designs and treatment.. Although the pig whipworm causes disease and losses in livestock, it does not cause disease in humans.. In contrast, the human whipworm infects around 1 billion people, mainly children in developing nations, and causes dysentery, malnourishment and impairment of physical and mental development.. Coauthor, Prof Robin Gasser, Faculty of Veterinary Science, said, The genes tells us about the proteins that this worm uses to interact with our immune systems.

The soil-transmitted helminths (also called geohelminths) are a group of intestinal parasites belonging to the phylum Nematoda that are transmitted primarily through contaminated soil. They are so called because they have a direct life cycle which requires no intermediate hosts or vectors, and the parasitic infection occurs through faecal contamination of soil, foodstuffs and water supplies. The adult forms are essentially parasites of humans, causing soil-transmitted helminthiasis (STH), but also infect domesticated mammals. The juveniles are the infective forms and they undergo tissue-migratory stages during which they invade vital organs such as lungs and liver. Thus the disease manifestations can be both local and systemic. The geohelminths together present an enormous infection burden on humanity, amounting to 135,000 deaths every year, and persistent infection of more than two billion people. Soil-transmitted helminths are typically from the following families of nematodes, ...
Infections with parasitic helminths (nematodes and trematodes) represent a significant economic and welfare burden to the global ruminant livestock industry. The increasing prevalence of anthelmintic resistance means that current control programmes are costly and unsustainable in the long term. Recent changes in the epidemiology, seasonality and geographic distribution of helminth infections have been attributed to climate change. However, other changes in environment (e.g., land use) and in livestock farming, such as intensification and altered management practices, will also have an impact on helminth infections. Sustainable control of helminth infections in a changing world requires detailed knowledge of these interactions. In particular, there is a need to devise new, sustainable strategies for the effective control of ruminant helminthoses in the face of global change. In this paper, we consider the impact of helminth infections in grazing ruminants, taking a European perspective, and identify
Author Summary Infections by parasitic worms are very common, and controlling them is a major medical and veterinary challenge. Very few drugs exist to treat them, and the parasites can develop resistance to these. In order to find new ways to control worm infections, understanding how our immune system responds to them is essential. Many important parasitic worm infections move through the host lung. In this study we show that a major secreted protein in the lung, Surfactant Protein D (SP-D), is essential for immunity to a parasitic worm infection. We found that this protein binds to worm larvae in the lung to help the immune system kill them. Infecting mice that do not express SP-D with worms demonstrates SP-D is important in this immune response. These mice are unable to launch an effective anti-worm immune response and have many more worms in their intestine compared to mice that do express SP-D. We also show that if we increase SP-D levels in the lung the mouse has better immunity to worms.
Research conducted at the University of Medicine and Dentistry of the New Jersey Medical School has established that the co-infection of tuberculosis and parasitic worms can complicate TB treatment.
Helminth parasitology has proven to be one of the fast-moving and inter-disciplinary research areas across a spectrum of scientific activities from genomics, immunology and tropical medicine. With rapidly increasing sequence information, new drug development for therapy, and intricate host-parasite molecular interactions, research on these organisms and the diseases they cause is becoming ever more exciting and relevant to global health. A key element in the success of helminth research has been the collaborative and interactive community of investigators working in this field.. This Conference series on the Molecular and Cellular Biology of Helminth Parasites has been an integral part of the rapid development of this whole field. The Conference started with the first two meetings in Edinburgh in 1997 and 1999, and moved to the island of Hydra, Greece in 2002. Subsequent conferences have been held in Hydra in 2005, 2008, 2010, 2012, and then annually since 2014.. All major areas of helminth ...
Helminth infection may modulate the expression of Toll like receptors (TLR) in dendritic cells (DCs) and modify the responsiveness of DCs to TLR ligands. This may regulate aberrant intestinal inflammation in humans with helminthes and may thus help alleviate inflammation associated with human inflammatory bowel disease (IBD). Epidemiological and experimental data provide further evidence that reducing helminth infections increases the incidence rate of such autoimmune diseases. Fine control of inflammation in the TLR pathway is highly desirable for effective host defense. Thus, the use of antagonists of TLR-signaling and agonists of their negative regulators from helminths or helminth products should be considered for the treatment of IBD.
DILI, Timor-Leste, 17 November 2005 - In Timor-Leste, a high proportion of the countrys children are malnourished: More than 40 per cent are below normal weight, and nearly half are stunted in growth. Parasitic worms are one of the reasons why so many Timorese children are suffering from poor health.
In the acute phase of helminth infections are the main manifestations are due to toxic-allergic effect of parasitic worms on the body. In patients with marked fever, skin rash, muscle pain, lymphadenopathy. Often develops abdominal syndrome (dyspepsia, abdominal pain), pulmonary syndrome (dry cough, bronchospasm, shortness of breath), hepatolienal syndrome (enlarged liver and spleen), asthenovegetative syndrome (apathy, fatigue, sleep disturbances, irritability).. In the chronic phase of helminthiasis is dominated by organ-specific lesions caused mainly mechanical traumatization of the place of parasitism of helminths. So, in determining the course of intestinal helminths are dyspepsia and abdominal pain. The malabsorption in the intestine is accompanied by the polyhypovitaminosis, progressive weight loss. Frequent companion of intestinal helminth infections is iron deficiency anemia. When a massive parasitic infestation may rectal prolapse, hemorrhagic colitis, intestinal obstruction.. In the ...
Although mankind has known about intestinal parasites for millennia, it has only been in the last century that scientists have recognized the diseases caused by zoonotic parasites. Soil-transmitted helminths (STHs), including Toxocara canis and Ancylostoma caninum, are an important subset of zoonotic parasites, and they have developed unique characteristics that allow them to infect humans and animals. Overt parasitism is no longer common in many developed nations; however, the subtle and varied symptoms associated with STH infection, along with the lack of experience and interest of the human healthcare industry, mean that many cases of zoonotic infection are missed. These diseases not only affect the health of humans, but they also have poverty-promoting effects. The lack of attention paid to these parasites in recent years has caused the World Health Organization to label them neglected zoonotic diseases. Human culture and individual behaviors are important risk factors for these diseases, ...
In this study, we took a multiomic approach toward investigating the effects of coinfection with soil-transmitted helminths and P. vivax. To our surprise, we found that the gut microbiota communities had a stronger association with malaria infection than with STH infections. We had previously reported, in both cross-sectional (20) and longitudinal (21) studies on the Orang Asli in Malaysia, that T. trichiura infection impacted microbial diversity and the composition of the microbiota in infected individuals. In contrast, the current study found that the microbiota of uninfected and STH-infected individuals are not significantly different (Fig. 4A; see also Fig. S5 in the supplemental material). This suggests that the environment in which the microbiota and STH exist (all the other cofactors, such as the diet, age, lifestyle, and other previous and current infections of the human host) may determine whether or not STH affect the gut microbiota. This could explain why the effects of STH on the gut ...
Two hairworms from Argentina, Gordionus porosus n. sp. and Gordionus ondulatus (Nematomorpha, Gordioidea), are described and illustrated. The cuticle of both species shows only 1 areolar type. Areoles of G. porosus are polygonal and surrounded by minute bristles and the interareolar groove is wide and with large pores. Gordionus ondulatus is characterized by rectangular or irregular areoles from which margins cuticular elongations project as finger-like structures, giving an undulated appearance. Comparing these species to the remaining American species of Gordionus, G. porosus is close to Gordionus violaceus by virtue of the large number of small bristles surrounding the areoles and can be distinguished by the shape of these bristles and by the arrangement and shape of the areoles. Gordionus ondulatus differs from the other species of the genus by its undulating margins. Giordinus lineatus and Giordinus violaceus have been reported in North America, Giordinus platycephalus in North and Central ...
Quantifying the burden of parasitic diseases in relation to other diseases and injuries requires reliable estimates of prevalence for each disease and an analytic framework within which to estimate attributable morbidity and mortality. Here we use data included in the Global Atlas of Helminth Infection to derive new global estimates of numbers infected with intestinal nematodes (soil-transmitted helminths, STH: Ascaris lumbricoides, Trichuris trichiura and the hookworms) and use disability-adjusted life years (DALYs) to estimate disease burden. Prevalence data for 6,091 locations in 118 countries were sourced and used to estimate age-stratified mean prevalence for sub-national administrative units via a combination of model-based geostatistics (for sub-Saharan Africa) and empirical approaches (for all other regions). Geographical variation in infection prevalence within these units was approximated using modelled logit-normal distributions, and numbers of individuals with infection intensities above
Parasite Immunology is a world journal dedicated to research on all aspects of parasite immunology in human and animal hosts. Emphasis has been placed on how hosts control parasites, and therefore the immunopathological reactions which happen within the course of parasitic infections. Extensive research shows that parasitic worms have the power to deactivate certain system cells, resulting in a gentler immune reaction. Often, such a response is useful to both parasite and host, consistent with Professor of Medical Microbiology Graham Rook of University College London. This immune relaxation is incorporated throughout the immune system, decreasing immune responses against harmless allergens, gut flora, and therefore the body itself. In their Parasite Immunology article on worms and viral infections, Dr. Kamal et al. explain why some parasitic worms aggravate the immune reaction. Because parasitic worms often induce Th2 cells and cause suppressed Th1 cells, problems arise when Th1 cells are ...
Implied under the rubric of the hygiene hypothesis is that helminth infection can protect against allergic disease. It is well known that helminths induce processes associated with type 2 immune responses, but they also induce important regulatory responses that can modulate these type 2-associated responses-modulation that influences responses to bystander antigens including allergens. Indeed, most epidemiological studies demonstrate a beneficial effect of helminth infection on atopy, but there are also convincing data to demonstrate that helminth infection can precipitate or worsen allergic inflammation/disease. Reasons for these disparate findings are much debated, but there is a school of thought that suggests that helminth-triggered type 2-associated responses, including IgE to cross-reactive aeroallergens, can offset the regulatory effects imposed by the same organisms. The cross-reactivity among helminths and allergenic tropomyosins dominated the antigen/allergen cross-reactivity field, but
This groundbreaking report allows us to envision a world free of parasitic worm infections. It is a call-to-action to have NTD elimination highlighted as a matter requiring urgent attention in the national agenda. The economic benefits of ending these diseases are profound across all levels of society, and require a locally owned multi-stakeholder approach, said Karen Palacio, Associate Vice President, Programs, The END Fund.. The report suggests that it is necessary for countries and stakeholders to go beyond the continuous treatment of disease and move towards preventing disease through improved sanitation programmes, health education, and data collection. The report also points out the need for governments to own and lead initiatives so that solutions are better tailored to local needs. As part of its analysis for the report, EIU explores the potential economic and social gains of ending parasitic worm infections in Ethiopia, Kenya, Rwanda, and Zimbabwe. Their analysis suggests that meeting ...

This volume covers research on the interaction of major helminth parasites with the immune system. The main focus of the e-book is the ability of helminths to subvert host immune responses, on the one hand. On the other hand, the immunological armamentarium of the host against invading parasites is described also in the light of new findings on innate and adaptive immunity. These include the discovery of a new category of lymphocytes, innate lymphoid cells, and the role of T helper cels such as Th1, Th2 and Th3 cells, T regulatory (Treg) and Th17 cells in helminth diseases and inflammation. The balance between these two T cell subsets during the various stages of helminth diseases is also discussed. The book concludes with a review of new therapeutic approaches to combat helminth parasites (biotherapy, vaccines and natural products). Immunity to Helminths and Novel Therapeutic Approaches provides updated information for medical students, clinicians and researchers in the fields of parasitology, ...

The mammalian immune system encounters an enormous diversity of foreign stimuli, including viruses, bacteria, protozoa, parasitic worms (helminths), and allergenic particles. Determining how these stimuli are sensed and distinguished is fundamental to our understanding of the immune response and accordingly to our therapeutic interventions. The discovery of Toll-like receptors in the 1990s established the paradigm that specific microbial ligands are detected by matching immune receptors. Many ligand-receptor pairs have since been identified, and our understanding of bacterial and viral type 1 detection is quite advanced. By contrast, very little is known about how the immune system first senses helminths and allergens, which give rise to a type 2 immune response. Indeed, it has not even been clear which cells first detect type 2 stimuli, let alone the underlying mechanisms.. We and others recently discovered that the immune response to intestinal helminth infection requires a specialized ...
Helminths aggravate anemia and malnutrition among school children. We studied this association in a cross-sectional study of 6- to 23-month-old Zanzibari children (N = 2322) and a sub-sample of 690 children matched on age and helminth infection status. Ascaris, hookworm, and Trichuris infections were diagnosed along with recent fever, malaria infection, mid-upper arm
Viability of developmental stages of Schistosoma mansoni quantified with xCELLigence worm real-time motility assay (xWORM) Gabriel Rinaldi, Alex Loukas, Paul J. Brindley, Jeff T. Irelan, Michael J. Smout, 2015. Infection with helminth parasites causes morbidity and mortality in billions of people and livestock worldwide. Where anthelmintic drugs are available, drug resistance is a major problem in livestock parasites, and a looming threat to public health. Monitoring the efficacy of these medicines and screening for new drugs has been hindered by the lack of objective, high-throughput approaches. Several cell monitoring technologies have been adapted for parasitic worms, including video-, fluorescence-, metabolism enzyme- and impedance-based tools that minimize the screening bottleneck. Using the xCELLigence impedance-based system we previously developed a motility-viability assay that is applicable for a range of helminth parasites. Here we have improved substantially the assay by using diverse ...
While the effects of deforestation and habitat fragmentation on parasite prevalence or richness are well investigated, host-parasite networks are still understudied despite their importance in understanding the mechanisms of these major disturbances. Because fragmentation may negatively impact species occupancy, abundance and co-occurrence, we predict a link between spatiotemporal changes in habitat and the architecture of host-parasite networks. For this, we used an extensive data set on 16 rodent species and 29 helminth species from seven localities of South-East Asia. We analysed the effects of rapid deforestation on connectance and modularity of helminth-parasite networks. We estimated both the degree of fragmentation and the rate of deforestation through the development of land uses and their changes through the last 20 to 30 years in order to take into account the dynamics of habitat fragmentation in our statistical analyses. We found that rapid fragmentation does not affect helminth ...

The new findings, published in PLOS Computational Biology, help demonstrate the evolutionary basis for allergy.. The study was led by Dr Nicholas Furnham from the London School of Hygiene & Tropical Medicine, with colleagues from the European Bioinformatics Institute (EMBL-EBI), the University of Cambridge, the University of Edinburgh and the Ugandan Ministry of Health.. The findings support the hypothesis that allergic reactions are a flawed antibody response towards harmless environmental allergens.. It is thought that part of our immune system has evolved to combat and provide immunity against infection by parasitic worms. However, in the absence of parasitic infection, this same arm of the immune system can become hyper-responsive and mistakenly target allergenic proteins in food or the environment. This results in an unregulated allergic response, which can sometimes be lethal.. The researchers used computational techniques to predict which proteins in parasitic worms would cause an immune ...
Parasitic worms infect billions of people worldwide. Current treatments rely on a small group of drugs that have been used for decades. A shortcoming of these drugs is their inability to target the intractable infectious stage of the parasite. As well-known therapeutic targets in mammals, nuclear receptors have begun to be studied in parasitic worms, where they are widely distributed and play key roles in governing metabolic and developmental transcriptional networks. One such nuclear receptor is DAF-12, which is required for normal nematode development, including the all-important infectious stage. Here we review the emerging literature that implicates DAF-12 and potentially other nuclear receptors as novel anthelmintic targets.. ...
Interleukin 25 (IL-25) is a major alarmin cytokine, capable of initiating and amplifying the type 2 immune response to helminth parasites. However its role in the later effector phase of clearing chronic infection remains unclear. The helminth Heligmosomoides polygyrus establishes long-term infections in susceptible C57BL/6 mice, but is slowly expelled in BALB/c mice from day 14 onwards. We noted that IL-25R (Il17rb)-deficient BALB/c mice were unable to expel parasites despite type 2 immune activation comparable to the wild-type. We then established that in C57BL/6 mice, IL-25 adminstered late in infection (days 14-17) drove immunity. Moreover when IL-25 and IL-4 were delivered to Rag1-deficient mice, the combination resulted in near complete expulsion of the parasite, even following administration of an anti-CD90 antibody to deplete innate lymphoid cells (ILCs). Hence, effective anti-helminth immunity during chronic infection requires an innate effector cell population that is synergistically ...

My research revolves around trying to answer this question: How can fundamental studies of developmental biology & gene regulation guide our search for next generation anthelmintic solutions?. Parasitic worms cause some of the most disfiguring, debilitating & chronic infectious diseases of human & animal populations across the globe. Reliance on limited drug classes to treat affected individuals & the lack of available vaccines to induce protective immunity suggests that current experimental approaches in identifying urgently needed anthelmintics have yet to deliver sustainable solutions.. Utilising both hypothesis-led & discovery driven research approaches my laboratory is developing new strategies for controlling parasitic helminths of biomedical importance. Our area of expertise is Schistosoma mansoni, one of the three main trematode species responsible for the neglected tropical disease Schistosomiasis. More than 200 million people suffer from this chronic & debilitating disease, with 90% of ...
Polarization of macrophages to M1 or M2 cells is important for mounting responses against bacterial and helminth infections, respectively. Jumonji domain containing-3 (Jmjd3), a histone 3 Lys27 (H3K27) demethylase, has been implicated in the activation of macrophages. Here we show that Jmjd3 is esse …
Soil-transmitted helminthiases (STH) are among the most common neglected tropical diseases (NTDs). Worldwide, it is estimated that 880 million children across 102 countries need treatment for these parasites. To eliminate morbidity from STH, the World Health Organization (WHO) recommends the periodical large-scale treatment of children in endemic areas.. Since 2010, this public health approach - also called preventive chemotherapy (PC) - has been implemented and scaled up to impressive numbers. In 2018, more than 500 million children received medicine for STH.. This progress is being made possible thanks to an innovative public-private partnership, resulting in the largest medicine donation in history and tireless efforts by program managers, teachers and volunteers who support the implementation of annual targeted treatment of children at risk of STH.. In a new paper published in Infectious Diseases of Poverty, we show how sustaining preventive chemotherapy for at least 5 consecutive years ...
Infections with parasitic worms have the potential to suppress allergic and inflammatory immune responses (27, 28). Our study provides evidence that such an effect can be exerted by a single immunomodulatory protein of a parasitic nematode, filarial cystatin (Av17). Application of cystatin in a murine model of OVA-induced airway inflammation and hyperreactivity during or even after allergen sensitization counteracted the Th2 effector mechanisms responsible for allergic airway disease in several ways. First, cystatin treatment significantly reduced the recruitment of inflammatory cells, particularly eosinophils, into the lungs, preventing the release of effector molecules that lead to tissue damage (29, 30). Second, cystatin lowered the production of allergen-specific and total IgE, resulting in less efficient sensitization of mast cells and basophils (31), as determined by decreased degranulation of basophils sensitized with sera of cystatin/OVA-treated mice (unpublished observation). Third, ...
This extensive compendium of medical and vertinary helminthology is the first adequate manual of its kind to be published in any language since the work of Professor A. Railliet in 1895 and will be welcomed by all workers in this dual field, because it is comprehensive, up-to-date and authoritative. It is dedicated to Professor Raphael Blanchard (1857-1919), the distinguished medical helminthologist, and to Professor Alcide Railliet (1852-1930), the equally distinguished veterinary helminthologist. The volume is divided into four parts: (1) general helminthology, (2) special helminthology, (3) definitive hosts of helminths and (4) intermediate hosts of helminths. Part I (pp. 1-76) includes a general consideration of parasitic worms; their adaptations to a parasitic existence; their evolution; their host relations, methods by which definitive hosts become infected, migration through the hosts' tissues, the tissue reactions provoked and their effects on both the host and the parasite; technics
INTRODUCTION: different brands Albendazole are commercially available and the efficacious brand/s is/are required for effective control of STHs infection. Thus, this study is aimed at determining the therapeutic efficacy of different brands of albendazole against soil transmitted helminths among school children of Jimma town. METHODS: a cross sectional survey for prevalence of geohelminths and a randomized trial for efficacy study of different brands of albendazole was conducted among students Mendera Elementary School from March 29 to April 29, 2010. Positive subjects were randomized into three treatment arms using lottery method. The collected stool samples were examined by the McMaster method. CRs were calculated using SPSS windows version 16 and ERRs were calculated using appropriate formula. RESULTS: of the 715 school children who had their stools examined, 326 were positive for STHs with a prevalence rate of 45.6%. The cure rates (CR) for A. lumbricoides, T. trichiura and Hookworm were 99.4, 59.9

CX3CR1GFP/PGRPdsRed reporter mice have previously been used to monitor trafficking of monocytes and neutrophils, respectively. With this new tool, we examined myeloid cell and neutrophil behavior during murine infection with the helminth, Nippostrongylus brasiliensis (Nb). Nb acutely infects the lungs leading to significant infiltration of PGRPdsRed neutrophils and CX3CR1GFP monocytes compared to naïve mice. Using ex vivo time-lapse confocal microscopy, we discovered that Nb infection increased chemotaxis of CX3CR1GFP monocytes and PGRPdsRed neutrophils. Because CX3CR1GFP expression is a loss of function knock-in mutation, we tested the function of CX3CR1 in the immune response to Nb. After inoculation with infective larvae, CX3CR1GFP mice were less susceptible to infection compared to wild-type mice and had lower worm counts and parasite eggs in the feces. Additionally, ATP cell viability assay revealed that worms recovered from reporter mice were less viable than worms isolated from wild-type ...
