Immunocompromised patients have high risk of infections from bacteria, viruses, fungi and parasites. One of these infections is those caused by Strongyloides stercoralis Immunocompromised patients are at risk of hyperinfection syndrome which is characterised with more systemic manifestation and a higher risk of morbidity and mortality. This can be complicated by coinfection with enteric organisms, specifically Gram-negative. Enterococci are Gram-positive cocci which are inhabitants of the human gastrointestinal tract...

The agouti ( Dasyprocta leporina ) is a New World wild rodent hunted for its meat in Trinidad and other Latin American countries. Studies on agouti under captive conditions have yielded some data on health-related aspects, but relatively very little is known about their wild counterparts. The environment of the agouti can influence the microflora and parasites harbored by the animals, which may contain zoonotic pathogens. Here, the microflora found on the nasal mucosa and sections of the intestinal tract and endoparasites of freshly shot agouti from various areas of Trinidad are described...

A comparative study was carried out to evaluate the Strongyloides stercoralis infections in children and dogs inside and outside the segregated settlement in Medzev, Eastern Slovakia, and a survey of the soil within the settlement was included. Applying the Koga agar plate (KAP) culture method and microscopy examination of stool samples collected from 60 Roma and 21 nonRoma children, no larvae of S. stercoralis were detected but eggs of three nematodes (Ascaris lumbricoides, Trichuris trichiura, and Enterobius vermicularis) and cysts of two protozoan endoparasites (Giardia duodenalis and Cryptosporidium spp...

Strongyloides stercoralis is a parasite that can cause death in immunocompromised people. A proper diagnosis is hence essential. The real-time polymerase-chain reaction (RT-PCR) is a novel, promising diagnostic method, that detects the DNA of the parasite in stool samples. In this retrospective study, we compared the sensitivity of agar plate coproculture (APC), an in-house immunofluorescence test (IFAT) and an in-house RT-PCR for the diagnosis of S. stercoralis infection. The study sample was composed by 223 samples...

The European wolf (Canis lupus) is a large carnivore species present in limited areas of Europe with several small populations still being considered as endangered. Wolves can be infected by a wide range of protozoan and metazoan parasites with some of them affecting free-living wolf health condition. On this account, an epidemiological survey was conducted to analyze the actual parasite fauna in Croatian wild wolves. In total, 400 individual faecal samples were collected during field studies on wolf ecology in the years 2002-2011...

The helminth Strongyloides stercoralis, which is transmitted through soil, infects 30-100 million people worldwide. S. stercoralis reproduces sexually outside the host as well as asexually within the host, which causes a life-long infection. To understand the population structure and transmission patterns of this parasite, we re-sequenced the genomes of 33 individual S. stercoralis nematodes collected in Myanmar (prevalent region) and Japan (non-prevalent region). We utilised a method combining whole genome amplification and next-generation sequencing techniques to detect 298,202 variant positions (0...

Strongyloides stercoralis is an intestinal nematode with a complicated lifecycle and auto-infection. In healthy individuals, this parasite usually does not cause any symptoms. But in immunocompromised patients, the symptoms vary from abdominal pain and discomfort to sepsis and death.Gastric infection and involvement by this nematode are rare and uncommon. Here we report 2 cases of Strongyloides stercoralis hyperinfection that were discovered in gastric biopsies in 2 immunocompromised patients. A gastric biopsy was taken for each patient and both showed cross sections of adult worms, eggs, and rhabditiform larvae of S...

Cancer may be induced by many environmental and physiological conditions. Infections with viruses, bacteria and parasites have been recognized for years to be associated with human carcinogenicity. Here we review current concepts of carcinogenicity and its associations with parasitic infections. The helminth diseases schistosomiasis, opisthorchiasis, and clonorchiasis are highly carcinogenic while the protozoan Trypanosoma cruzi, the causing agent of Chagas disease, has a dual role in the development of cancer, including both carcinogenic and anticancer properties...

The nematode genus Strongyloides consists of fairly species-specific small intestinal parasites of various vertebrates, among them the human pathogen S. stercoralis. Between the parthenogenetic parasitic generations these worms can also form single facultative sexual free-living generations. In addition to their primary hosts, several species can also live more or less well in other permissive hosts, which are sometimes not very closely related with the normal host. For example, S. stercoralis can also infect dogs and non-human primates...

BACKGROUND & OBJECTIVES: Diarrhoea is the main clinical manifestation caused by intestinal parasitic infections in patients, with special reference to transplant recipients who require careful consideration to reduce morbidity and mortality. Further, molecular characterization of some important parasites is necessary to delineate the different modes of transmission to consider appropriate management strategies. We undertook this study to investigate the intestinal parasitic infections in transplant recipients with or without diarrhoea, and the genotypes of the isolated parasites were also determined...

BACKGROUND: Soil-transmitted helminthiases (hookworms, Ascaris lumbricoides and Trichuris trichiura) are extremely prevalent in school-aged children living in poor sanitary conditions. Recent epidemiological data suggest that Strongyloides stercoralis is highly unreported. However, accurate data are essential for conducting interventions aimed at introducing control and elimination programmes. METHODS: We conducted a cross-sectional survey of 396 randomly selected school-aged children in Amhara region in rural area in north-western Ethiopia, to assess the prevalence of S...

Strongyloides venezuelensis is a parasitic nematode of rodents that is frequently used to obtain heterologous antigens for immunological diagnosis of human strongyloidiasis. The aim of this study was to identify antigens from filariform larvae of S. venezuelensis for immunodiagnosis of human strongyloidiasis. Soluble and membrane fractions from filariform larvae of S. venezuelensis were obtained in phosphate saline (SS and SM) and in Tris-HCl buffer (TS and TM), and were analysed by Western blotting. Different antigenic components were recognized by IgG antibodies from the sera of strongyloidiasis patients...
