Soil-transmitted helminths (STHs) are intestinal parasitic nematodes that infect humans, and are transmitted through contaminated soil. These nematodes include the large roundworm (Ascaris lumbricoides), whipworm (Trichuris trichiura), and hookworm (Ancylostoma ceylanicum, Ancylostoma duodenale, and Necator americanus). Nearly 1.5 billion people (~24% of the population) worldwide are infected with at least one species of these parasites, burdening the poor, in particular, children and pregnant women. To combat these diseases, the WHO only recognizes four anthelmintic drugs, including the preferred drug, albendazole, for mass drug administration (MDA)...

The main aim of the study was to evaluate associations between morphological variability of Trichuris females from sheep and roe deer and their rDNA polymorphism in whipworm populations from the Czech Republic. The results introduced the use of new molecular markers based on the internal transcribed spacer (ITS)1-5.8S RNA-ITS2 region polymorphisms, as useful tools for the unambiguous differentiation of congeners Trichuris ovis and Trichuris discolor. These markers revealed both parasites in roe deer and in sheep; however, T...

Gastrointestinal parasites are a common problem in pigs in India. The important risk factors include coprophagic behaviour of pigs and their free access to garbage. To investigate the gastrohelmenthic spectrum in pigs of Punjab, we examined 265 faecal samples from farm (n = 47) and scavenging pigs (n = 218) using faecal floatation method. Ascaris suum, unsporulated oocysts, Trichuris spp. and Strongyloides were recorded in 27.5, 15.4, 1.8 and 4.5 % of the pig faecal samples, respectively. Overall prevalence was significantly higher in pigs >1 year (56...

Intestinal helminth infections constitute a major health problem in low socio-economic communities worldwide. A cross-sectional study was conducted in children aged between 12 and 60 months. A structured questionnaire was used to collect socio-demographic data and stool samples were subjected to direct smear, stained with Lugol's iodine, and formaldehyde-ether concentration techniques to determine the prevalence of intestinal helminth infections. The circumference of each child's left mid upper arm (MUAC) was measured using standard procedures...

Two new species of the genus Trichuris (Nematoda: Trichuridae) parasitic in the old endemic murids of Indonesia are described: T. musseri sp. nov. from Echiothrix centrosa (Murinae: Rattini) in Sulawesi and T. mallomyos sp. nov. from Mallomys rothschildi (Murinae: Hydromyini) in Papua Indonesia. Both species are characterized by having a gradually tapered and sharply pointed distal end of the spicule, being readily distinguished from most of the congeners known from murid rodents. Trichuris musseri is readily distinguished from T...

Roundworms belong to a diverse phylum (Nematoda) which is comprised of many parasitic species including whipworms (genus Trichuris). These worms have adapted to a biological niche within the host and exhibit unique morphological characteristics compared with other nematodes. Although these adaptations are known, the underlying molecular mechanisms remain elusive. The availability of genomes and transcriptomes of some whipworms now enables detailed studies of their molecular biology. Here, we defined and curated the full complement of an important class of enzymes, the protein kinases (kinomes) of two species of Trichuris, using an advanced and integrated bioinformatic pipeline...

The present study were undertaken to compare two isolation techniques (centrifugal flotation and sedimentation) for recovering taeniid eggs from faecal samples, to identify E. granulosus DNA from taeniid eggs by PCR, and to determine the prevalence of E. granulosus in dogs in villages. Faecal samples were collected from 100 dogs in Ankara province. Taenia spp. eggs were found in 27% of dogs faeces. Echinococcus granulosus-specific PCR was obtained in 14 (51.85%) of the taeniid eggs-positive samples. As well as finding Taenia eggs in dogs' faeces, we also found eggs of some helminthic parasites; such as Dipylidium caninum, Toxocara canis, Toxascaris leonina, Trichuris sp...

Ingestion of eggs (ova) of the porcine nematode parasite Trichuris suis (TSO) may reduce the severity of autoimmune disorders, however the development of TSO treatment as a useful therapy for autoimmune diseases is hampered by a lack of knowledge on the development of the parasite and the nature of the local immune responses in humans. Here, we used colonoscopy to investigate the development of T. suis and related mucosal and systemic immune responses during TSO treatment in an intestinally healthy male volunteer...

BACKGROUND: Studies have shown that households using sludge from human excreta for agriculture are at an increased risk of soil transmitted helminths. However, while use of ecological sanitation (EcoSan) latrines is increasing in most African countries including Malawi, few studies have been done to check whether use of such sludge could potentially increase the prevalence of helminthic infections among household members as a results of exposure to faecal sludge/compared to use of traditional latrines...

BACKGROUND: Intestinal parasitic infections remain prevalent and constitute a public health problem in certain rural areas of Thailand. Village health volunteers (VHVs), who are members of a Thai healthcare alliance, function as key providers of health prevention measures, disease control, and health education and share national health promotion campaigns with community members. This study is aimed at evaluating the prevalence, intensity, and risk factors for intestinal parasitic infection in VHVs in order to design community awareness and health education campaigns for the target population...

T-helper 2 (Th2) cell responses defend against parasites. Although dendritic cells (DCs) are vital for the induction of T-cell responses, the DC subpopulations that induce Th2 cells in the intestine are unidentified. Here we show that intestinal Th2 responses against Trichuris muris worms and Schistosoma mansoni eggs do not develop in mice with IRF-4-deficient DCs (IRF-4(f/f) CD11c-cre). Adoptive transfer of conventional DCs, in particular CD11b-expressing DCs from the intestine, is sufficient to prime S. mansoni-specific Th2 responses...

BACKGROUND: Gastrointestinal nematode (GIN) infections are the main impediments that restrict the welfare and productivity of small ruminant in the world. Effective management of GINs in grazing sheep relies heavily on the use of highly efficacious anthelmintic drugs. However, anthelmintic resistance is becoming a significant concern in the world, and this phenomenon severely threatens the potential utilisation of this control strategy. Therefore, this study was conducted 1) to evaluate the efficacy of commonly used anthelmintic on GINs in naturally infected sheep and 2) to assess the farmers' perception on anthelmintics utilisation practices in Dabat district, Northwest Ethiopia...

Most studies evaluating epidemiologic relationships between helminths and HIV have been conducted in the pre-ART era, and evidence of the impact of helminth infections on HIV disease progression remains conflicting. Less is known about helminth infection and clinical outcomes in HIV-infected adults receiving antiretroviral therapy (ART). We sampled HIV-infected adults for eight gastrointestinal parasites and correlated parasitic infection with demographic predictors, and clinical and immunologic outcomes. Contrasting with previous studies, we measured parasitic infection with a quantitative, highly sensitive and specific polymerase chain reaction (PCR) method...

To better control gastrointestinal nematode infections in humans and animals, it is important to understand the strategies used by these parasites to modulate the host immune system. In this regard, molecules released by parasites have been attributed crucially important roles in host-parasite negotiations. We characterized the excretory/secretory (E/S) microRNA (miRNA) and protein profiles from the mouse gastrointestinal nematode parasite Trichuris muris. Released miRNAs were subjected to miRNA sequencing and E/S proteins were analysed by mass spectrometry...

INTRODUCTION: Suppressor of cytokine signaling 3 (SOCS3) is a tumour suppressor, limiting intestinal epithelial cell (IEC) proliferation in acute inflammation, and tumour growth, but little is known regarding its role in mucosal homeostasis. Resistance to the intestinal helminth Trichuris muris relies on an "epithelial escalator" to expel the parasite. IEC turnover is restricted by parasite-induced indoleamine 2,3-dioxygenase (IDO). METHODS: Mice with or without conditional knockout of SOCS3 were infected with T...

Trichuris trichiura infection is a common helminth infection, which is transmitted via soil, with worldwide distribution, especially in rural areas of developing countries. Occasionally, sporadic cases occur in non-endemic, developed areas due to the widespread of immigration. We experienced a case of Trichuris dysentery syndrome in a young North Korean defector, who had been suffering from chronic abdominal pain for 10 years. He is relatively short and thin compared with his older brother. Unexpectedly, the diagnosis, made by a colonoscopy, revealed numerous, small, white, and gently moving worms at the cecum and ascending colon...
