Filarial nematodes are capable of causing significant disease with long-term ramifications in humans and animals. Intermediate hosts, or vectors, are involved in all instances. Interestingly, although they infect different locations in their respective hosts, the filarial worm species are remarkably similar in many ways.. In humans, the most prevalent filarial infections can result in blindness (Onchocerca volvulus) or lymphedema (Brugia malayi, B. timori and Wuchereria bancrofti).. The intermediate hosts of O. volvulus are blackflies, which transfer infective larvae to a susceptible person approximately 2 to 3 weeks after becoming infected by microfilariae in a blood meal from an infected host. The infective larvae migrate into the subcutaneous tissue in the competent host and form nodules under the surface of the skin while maturing into adult worms. Adult female O. volvulus produce 750 to 1600 microfilariae daily [8, 9]. When adult worms or microfilariae die, the resulting inflammatory ...

Parasitic filarial nematodes are often tolerated in their human hosts for decades, with little evidence of pathology, due to parasite-induced immune modulation. The consensus of opinion, to date, is that such parasites achieve prolonged survival as a result of their active modulation of the hosts immune system by secreted immunomodulatory molecules. Consistent with this, the excretory-secretory protein of Acanthocheilonema vitae, ES-62, has been shown to exhibit immunomodulatory activities that are broadly Th2/anti-inflammatory in nature. Dendritic cells are specialised antigen (Ag)-presenting cells critical for initiating and regulating immune responses. They stimulate T cells and produce cytokines that have important immuneregulatory functions. To date, more than 6 different DC subtypes have been identified that arise from at least two different cell lineages. These subtypes are not only phenotypically distinct but they are also thought to perform different functions and be restricted to ...

Wolbachia, a gram negative bacterial endosymbiont belonging to the Rickettiales, has been described in the body of various species of filarial nematodes (Sironi et al. 1995; Bandi et al., 1998, Casiraghi et al., 2001). These bacteria are present in the lateral chords of both males and females, in the reproductive apparatus of females and also in the larvae present in the vector (Bandi et al., 2001). Wolbachia has also been shown to be transovarially transmitted from female worms to the offspring. In addition, a 100% prevalence of infection in the filarial species positive for Wolbachia is suggestive of an obligatory symbiosis between bacteria and its host (Bandi et al., 2001). Furthermore, drugs like tetracycline, known to be effective against Rickettsia-like bacteria, have been shown to cause detrimental effects on filarial nematodes which harbour Wolbachia, and no effects on filarial nematodes which do not harbour these bacteria (Bandi et al., 1999, Hoerauf et al., 1999; Langworthy et al., ...

In humans, they may infect the lymphatic vessels and lymphatic organs, circulatory system, connective tissues, subcutaneous tissues, and serous cavities. Typically, the female produces microfilariae (larvae), which may be sheathed or sheathless. They reach the peripheral blood or lymphatic vessels, where they may be ingested by a bloodsucking arthropod (a mosquito, gnat, or fly). In the intermediate host, they transform into rhabditoid larvae that metamorphose into infective filariform larvae. These migrate to the proboscis and are deposited in or on the skin of the vertebrate ...

It was recently demonstrated that the lone star tick Amblyomma americanum could harbor filarial nematodes within the genus Acanthocheilonema. In this study, Ixodes scapularis (deer) ticks collected from Southern Connecticut were evaluated for their potential to harbor filarial nematodes. Non-engorged nymphal and adult stage Ixodes scapularis ticks were collected in Southern Connecticut using the standard drag method. In situ hybridization with filarial nematode specific sequences demonstrated the presence of filarial nematodes in Ixodes ticks. Filarial nematode specific DNA sequences were amplified and confirmed by direct sequencing in Ixodes nymphal and adult ticks using either general filarial nematode or Onchocercidae family specific PCR primers. Phylogenetic analysis of the 12S rDNA gene sequence indicated that the filarial nematode infecting Ixodes scapularis ticks is most closely related to the species found in Amblyoma americanum ticks and belongs to the genus of Acanthocheilonema.

Background & objectives: Dirofilaria immitis is a filarial nematode that causes heartworm disease in domestic as well as wild canines and felines; and cutaneous or pulmonary infections in humans. The purpose of the study was to estimate the prevalence of D. immitis in domestic dogs in Tabasco, Mexico and to assay mosquitoes temporally and spatially associated with dogs for evidence of infection. Methods: Blood was collected from 1050 dogs in 1039 houses during a random household survey performed in 2016 and 2017. Genomic DNA was extracted and assayed by polymerase chain reaction (PCR) using pan-filarial primers and various species-specific primers. Dog owners were interviewed using a structured questionnaire designed to collect information on factors that may impact the occurrence of filarial infection. The association between canine dirofilariasis prevalence and factors likely to impact infection was determined by univariate logistic regression analysis, followed by multivariate binomial ...

Recent studies have revealed expansion by an array of Filarioid nematodes into the northern boreal region of Finland. The vector-borne nematode, Setaria tundra, caused a serious disease outbreak in the Finnish reindeer population in 2003-05. The main aim of this study was to understand the outbreak dynamics and the rapid expansion of S. tundra in the sub arctic. We describe the vectors of S. tundra, and its development in vectors, for the first time. Finally we discuss the results in the context of the host-parasite ecology of S. tundra in Finland Development of S. tundra to the infective stage occurs in mosquitoes, (genera Aedes and Anopheles). We consider Aedes spp. the most important vectors. The prevalence of S. tundra naturally infected mosquitoes from Finland varied from 0.5 to 2.5%. The rate of development in mosquitoes was temperature-dependent. Infective larvae were present approximately 14 days after a blood meal in mosquitoes maintained at room temperature (mean 21 C), but did not develop in

Filarial nematodes harbour intracellular endosymbiotic bacteria, which have been assigned to the genus Wolbachia. These bacteria appear to play an important role in the pathogenesis of filarial diseases through their lipopolysaccharides. In view of the presence of Wolbachia endosymbionts in the body of filarial nematodes, one might also expect that proteins from these bacteria play an antigenic role in humans and animals affected by filariases. To test this hypothesis, we produced in recombinant form the surface protein WSP and a portion of the cell-cycle protein FTSZ from the Wolbachia of Dirofilaria immitis. Western immunoblot assays were then performed using cat sera to test the immunogenicity of these proteins. Sera were collected from owners cats, which were either sero-negative or sero-positive for D.immitis and from cats before and after experimental infection with D.immitis. FTSZ was recognized in Western blots by sera from both positive and negative cats and from both uninfected and ...

Abstract A small particle size formulation of 4-isothiocyanato-4′-nitrodiphenylamine has been found to have high chemotherapeutic activity when administered as a single dose to jirds infected with the filarial worm, Brugia pahangi.

Eggs are passed through the feces of an infected definitive host, usually a mammalian herbivore including rabbits, sheep, cattle, and rodents.[6] Under certain environmental conditions, which include optimal temperature and humidity, larvae hatch from eggs after several days. Hatched rhabditiform larvae grow on vegetation or within soil. After 5 to 10 days, two molts (L1 & L2) have occurred and the parasite becomes a filariform (L3) larvae that is infectious. Infection in mammals occurs upon ingestion of infective filariform (L3) larvae. The larvae reaches the small intestine to reside and mature into adult worms within their definitive hosts. Infections in humans may occur as incidental infections.[7] Trichostrongylus consists of multiple species that relate to each of its host, when it comes to parasitic survival and infection. For example, Trichostrongylus affinis primarily infects cottontail rats, Trichostrongylus sigmodontis affects hispid cotton rat, and marsh rice rat, and ...

Microarray technology permits high-throughput comparisons of gene expression in different parasite stages or sexes and has been used widely. We report the first use of this technology for analysis of gene expression in filarial male and female worms. The slide array (comprised of 65-mer oligos representing 3569 EST clusters) was spotted with sequences selected from the extensive Brugia malayi EST database (). Arrays were hybridized with Cy dye labeled male and female cDNA. The experimental design included both biological and technical (dye-flip) replicates. The data were normalized for background and probe intensity, and the relative abundance of hybridized cDNA for each spot was determined. Genes showing two-fold or greater differences with P,0.05 were considered gender-regulated candidates. One thousand one hundred and seventy of 2443 clusters (48%) with signals above threshold in at least one sex were considered as gender-regulated gene candidates. This included 520 and 650 clusters ...

Heartworm: Dirofilaria immitis. A common parasite of dogs in many parts of the world that occurs in other animals, including cats, but rarely infects humans. The adult worms, which are up to 10 inches (25 cm) in length, typically live in the dogs pulmonary artery and right side of the heart. Inflammation and thickening of the heart may result in heart failure, respiratory insufficiency, chronic cough, and vomiting. The disease can be fatal. The female worms produce microfilariae that are found in the dogs blood. The microfilariae are ingested by a mosquito when it feeds on a dog, the microfilariae mature into infective juveniles in the vector, and the infection is transmitted to a new host when the mosquito feeds. Many species of mosquitoes serve as vectors for the heartworm. ProHeart 6, a twice-a-year time-released heartworm medication, was recalled in 2004 at the request of the FDA after thousands of dogs suffered adverse reactions, including liver and bleeding abnormalities followed in some ...

Many patients infected with filarial worms have no symptoms, but those who develop disfiguring lymphatic filariasis -- more commonly known as elephantiasis -- often struggle with discrimination and rejection. Now, researchers have quantified that burden, reporting in PLOS Neglected Tropical Diseases that lymphatic filariasis patients in Nigeria have about four times the rate of depression as other adults there.

Dirofilaria immitis, the canine heartworm, is one of the most important filaroids parasite in carnivores. The dog and its close relative are natural hosts, but infection also occurs in cat, wild carnivores and man. Adult heartworms normally are found in the pulmonary arteries. Female kind of Dirofilaria immitis frees its microfilaria in blood stream and microfilaria are distributed by circulatory system throughout the body. Several species of mosquitoes are as intermediated hosts. This study was done within 8 months in six areas susceptible to infection in the vicinity of Tabriz. 60 dogs (between 1- 4 years olds) were caught by strychnine poisoned meat and were necropsied. In examination of hearts of dogs, Dirofilaria immitis is found in 19 cases (31.6%) and all worms were located in right ventricle and in right arteries. There were no worms in plumnary arteries. In positive cases at least 1 worm and at most 18 worms were observed. The intensity of infection in old dogs was much greater than ...

Author Summary Brugia malayi is a nematode which causes lymphatic filariasis in South and South-East Asia. Most infected people harbour many millions of the microfilarial stage of the parasite in their blood stream and yet they show few visible symptoms of disease. Vascular endothelial cells (EC) line the blood vessels and are therefore in direct contact with microfilariae. Since vascular EC are potent immune cells functioning in the production of both immune mediators and regulating the migration of immune cells from the blood into the tissue, we have established an in vitro model in which to test the effect of live Mf upon vascular EC function. Strikingly, we observed that Mf exposure caused reduced transendothelial migration of neutrophils and monocytes, but not lymphocytes. However, microfilariae stimulated EC production of few pro-inflammatory mediators. Additionally, while filarial infection is known to stimulate mediators that increase blood vessel formation in vivo, live microfilariae promoted

Abstract A 4.5-mm filarial worm was removed from the anterior chamber of the left eye of a 56-year-old man who had lost the sight in the right eye due to trauma some years earlier. The worm was removed intact through an upper scleral incision with a corneal based flap. Within 2 months vision was normal. The worm was identified as a sexually mature male of an undescribed species of Loaina Eberhard and Orihel 1984, a genus related to Loa and Dirofilaria.

Heartworm treatment is a very important part of dog health care. One common parasite is the dirofilaria immitis, a roundworm parasite that travels from host to host through the blood, transferred by mosquitoes biting multiple victims. The worm itself is a filament-like, slim worm that completes its life cycle in mammals. Check below for more info and related dog treatments and care.

Wolbachia is the most widespread bacterial endosymbiont. It is found in about 40% of all terrestrial arthropods, and in filarial nematodes. Among Wolbachia strains, multiple genetically distinct lineages can be differentiated. These lineages differ in their host spectrum, their prevalence and in the phenotypes they can induce in their hosts. I am interested in reconstructing the evolutionary history of these Wolbachia lineages in order to understand which evolutionary transitions have occurred at what time in the history of Wolbachia ...

p53 is a key regulator of the DNA damage-induced checkpoint in mammals (reviewed in Sancar et al., 2004). cep-1, the C. elegans homolog of p53, is required for DNA damage-induced apoptosis in the C. elegans germ line, but not for programmed cell death occurring during worm development nor physiological (radiation-independent) germ cell death (Schumacher et al., 2001; Derry et al., 2001). Despite the differences in the three-dimensional structure of the DNA binding domain between CEP-1 and human p53 (Huyen et al., 2004) its role in the DNA damage checkpoint appears to be conserved. Furthermore, CEP-1 can induce apoptosis in mammalian cells and this induction can be inhibited by iASPP, an evolutionarily conserved inhibitor of p53 (Bergamaschi et al., 2003). Several genes have been identified that either regulate cep-1 activity or are regulated by cep-1. The C.elegans iASPP ortholog, ape-1 (apoptotic enhancer) is a conserved inhibitor of cep-1. ape-1(RNAi) results in an increase in cep-1-mediated ...

Following the suggestion of Sidney Brenner to document all the cells inCaenorhabditis elegans, Bob Horvitz and John Sulston in 1977 published a map of the worms development, noting also that 111 cells were born only to die shortly thereafter. By 1990 Horvitzs group had identified a small number of genes that controlled the deaths of these cells, when they electrified the community by announcing that the primary killer gene was not only a protease but a known protease.. This discovery burst open the entire subject of apoptosis, leading quickly to recognition of the caspase family of proteases and generating the fervent activity that we now see in research and biotechnical and pharmaceutical efforts to directly or indirectly control the activity of caspases and thereby apoptosis. For this and many subsequent discoveries, Horvitz, Sulston, and Brenner were awarded the 2002 Nobel Prize in Physiology or Medicine. ...

A role for altered endothelial cell function is emerging in the pathogenesis of disease. We have previously demonstrated that Dirofilaria immitis, the canine heartworm, depresses endothelium-dependent responses and alters the mechanism of relaxation in the in vivo femoral artery of infected dogs. Exposure of rat aorta to the parasite or parasite-conditioned medium selectively depresses endothelium-dependent relaxation. D. immitis is closely related to the major human filarial pathogens. This study was designed to examine the effect of chronic infection with the filarial nematode Brugia pahangi on endothelium-mediated responses of the rat aorta in vitro. We tested the hypothesis that endothelium-dependent responses are depressed in the aorta from rats infected with B. pahangi. Rings of thoracic and abdominal aorta were suspended in muscle baths for measurement of isometric tension. Dose-response relations to norepinephrine, endothelium-dependent dilators (acetylcholine, histamine, and A23187), ...

Heartworm, Dirofilaria immitis, is a filarial nematode parasite that usually infects dogs or other canines, but can also infect cats, foxes, ferrets, and sea lions. The adult worms live in the right ventricle of the heart, hence their common name. After the adults mate, they produce microscopic larvae known as microfilariae, which are ingested by mosquitos when they bite the mammalian host. The larvae complete their development in the mosquito and then are transmitted to a new host when she feeds again. Although most dogs do not show signs of infection, in some cases worms can cause issues and need to be treated. However the treatments are sometimes risky because the dead worms can get carried to the lungs and cause respiratory distress or failure. Preventative therapies, such as giving dogs the drug ivermectin, are effective and safe. Heartworm are also hosts to the endosymbiotic bacteria, Wolbachia (see January 12th ...

Dirofilariasis is caused by Dirofilaria immitis and D. repens, parasitic nematodes transmitted by mosquitoes. The heartworms harbour the bacterial endosymbionts Wolbachia, which are essential for worm development, fecundity and survival. Corallopyronin A (CorA) has efficacy against the intracellular Wolbachia of filarial nematodes. Experiments in mice and jirds show that all worms were depleted of their Wolbachia by more than 98%, resulting in blocked larval development and phenotypically altered worms. The results indicate the potential of CorA to effectively kill filarial nematodes in the larval stages as well as adult worms. Thus, this antibiotic is a good option for prophylactic as well as therapeutic treatment. No toxicity against eukaryotic cells or the treated rodents was detected. Pharmacokinetic data show that the antibiotic is amenable to oral administration. Based on the present results CorA will be administered once a day for two to a maximum of four weeks. CorA is a non-competitive ...

Chitinasen sind wichtigen Moleküle im Lebenszyklus parasitischer Fadenwürmer und bedeutende Medikamenten- und Impfstoffziele. Hier wurden drei Chitinasesequenzen (I, II und III) durch Charakterisierung von 9 Klonen aus einer Genbank von Acanthocheilonema viteae gefunden. Die Anzahl der drei sehr homologen Chitinasegene wurde durch Southern-Blot bestätigt. Die größten Unterschiede sind in den Exons zu finden, die die Serin-Threonin-reiche Domäne der Chitinasen codieren. Diese Domäne ist in Sequenz III ca. 10fach länger als in Sequenz I. Sequenz I und III haben Eigenschaften eines transkribierten Genes: ein Startcodon, ein offener Leserahmen, ein Stopcodon und ein Polyadenylierungssignal. Sequenz II fehlt das erste Exon mit dem Startcodon. Bei Durchmusterung einer cDNA-Bibliothek adulter A. viteae Würmer bzw.

One of the most rapidly increasing human public health problems is obesity, whose sequelae like type-2 diabetes, represent continuously worsening, life-long conditions. Over the last 15 years, data have begun to emerge from human and more frequently, mouse studies, that support the idea that parasitic worm infection can protect against this condition. We have therefore investigated the potential of two synthetic small molecule analogues (SMAs) of the anti-inflammatory Acanthocheilonema viteae product ES-62, to protect against metabolic dysfunction in a C57BL/6 J mouse model of high calorie diet-induced obesity. We found weekly subcutaneous administration of the SMAs in combination (1 μg of each), starting one week before continuous exposure to high calorie diet (HCD), decreased fasting glucose levels and reversed the impaired glucose clearance observed in male mice, when measured at approximately 7 and 13 weeks after exposure to HCD. Fasting glucose levels were also-reduced in male mice fed a ...

During some stages in their life cycle, Plasmodium spp. (malaria), Babesia spp., Trypanosoma spp., Leishmania donovani, and the filariae are detectable in human blood. Plasmodium and Babesia species are found within the RBCs; trypanosomes and microfilariae, the larval stage of filariae, are found outside the RBCs; and Leishmania amastigotes are occasionally found within monocytes. Trypanosomes and microfilariae, which frequently are present in low numbers, exhibit motility in freshly collected blood films, and this can aid in their detection. However, species identifications of all blood parasites are usually made from either or both of two types of stained blood films: a thin film and a thick film. These films can be made from whole or anticoagulated blood or from the sediment of a variety of procedures designed to concentrate trypanosomes and microfilariae in the blood. Although the films are clearest when stained with Giemsa stain, many infections are detected and diagnosed by using Wright's

Vasile seemed like one of the lucky strays who had escaped a serious injury or health problem.. In fact, he seemed surprisingly healthy the day we rescued him.. But, Dirofilaria Immitis is a silent killer.. Vasile lived with us for 5 weeks and passed away on May 2019.. Vasile is not the first dog we have rescued and then lost to heartworm disease, and, sadly, he wont be the last. Stray dogs are extremely vulnerable to contracting this fatal disease because they do not receive a heartworm preventive.. We can only hope that the next infected stray we rescue can be saved with treatment. In the meantime, we can continue to protect the dogs at our sanctuary who are not infected. Every one of our 650 dogs receives the 6-month heartworm prevention treatment from spring to fall.. The 6-month heartworm prevention treatment for all 650 dogs at our ROLDA sanctuary costs…. But a donation of €49 can protect 1 dog for 7 months against this deadly heartworm disease.. Other ways you can protect ROLDA ...

Heartworm treatment is a very important part of dog health care. One common parasite is the dirofilaria immitis, a roundworm parasite that travels from host to host through the blood, transferred by mosquitoes biting multiple victims. The worm itself is a filament-like, slim worm that completes its life cycle in mammals. Check below for more info and related dog treatments and care.

Mosquito menace is not a new problem to mankind. Only the magnitude of the problem has grown into very serious proportions in those insanitary and unde-r developed countries where it has not been tackled on a scientific basis as in USA and Japan. While as a disease vector the mosquito spreads malarial, filarial, brain fever,dengue,chikungunya and other viral fevers (AIDS to some extent?) on a large scale, as a pest it causes unbearable discomfort and annoyance which results in restlessness, loss of sleep and nervous irritation.Reduced milk yield from cattle and even death of live-stock is reported from the attack of mosquitoes. Out of nearly 4000 spices of mosquitoes, only about 60 spices are harmful to man, causing extensive human suffering and loss of life,becoming an economic burden particularly in tropical countries. Of the 60 and odd million people that live in the filarial tracts of our country, nearly one-fourth live in the Southern states. Of the 500 million Malaria cases every year ...

The interplay of active and repressive histone modifications is assumed to have a key role in the regulation of gene expression. In contrast to this generally accepted view, we show that the transcription of genes temporally regulated during fly and worm development occurs in the absence of canonically active histone modifications. Conversely, strong chromatin marking is related to transcriptional and post-transcriptional stability, an association that we also observe in mammals. Our results support a model in which chromatin marking is associated with the stable production of RNA, whereas unmarked chromatin would permit rapid gene activation and deactivation during development. In the latter case, regulation by transcription factors would have a comparatively more important regulatory role than chromatin marks.. ...
