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 ...

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 ...
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.

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 ...

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 ...

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. Than about 2 Months or so later I ...

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. Knowing the worms molecular landscape could be very useful in starting to understand autoimmune diseases in humans.". The pig whipworm genome also provides a model to study the human parasite.. The study involved 11 institutions ...

10 meter long, 25 year old tape worms living in human and animal digestive systems are the subjects for the latest research project at the University of Wales, Aberystwyth (UWA). A group of scientists led by Dr Peter Brophy and Professor John Barrett of the University`s Institute of Biological Sciences are taking a new perspective on how parasitic worms survive for long periods of time within their human and animal hosts. The work is supported by the Biotechnology and Biological Sciences Research Council who are providing a £231,512 grant to fund the study. Whilst some UK research groups are looking at the problem via the hosts` perspective - that there are `wormy` animals/humans particularly prone to infection and what factors trigger the expulsion of the worm from the host - we are looking at the problem from the worm`s point of view, says Dr Brophy. We will be investigating which components (proteins) in the parasitic worms are crucial in helping it to survive for very long periods, ...

Then, lets take a look inside your intestines. Even if you arent among those who harbour cute little parasitic worms (or, for tapeworm hosts, cute big parasitic worms), your intestines are full of tiny creatures hopping, skipping and jumping around, from bacteria to yeasts. Its more than a rain forest in there in terms of the richness of life, more than a coral reef. And you cannot survive without those microorganisms. You are dependent on them to keep you alive. For one thing, some of them break down cellulose in the plant matter you eat, thus liberating the interior of the cells to your digestive juices. For another, they, even those whose only purpose of existence is to nibble fastidiously at fragments of your forming faeces, aggressively block out the others - the millions upon millions of less than pleasant microorganisms you swallow each day. ...
