background: dog is known to act as definitive host for some parasites that cause important diseases in man and animals. the aim of the present study was to determine the prevalence of neospora caninum and other intestinal parasites in dogs in khorasan razavi province, iran. methods : a cross-sectional study was done concerning frequency of n. canium and other in­testinal parasites in dogs in ma...

The roles of Th1 and Th17 responses as mediators of host protection and pathology in the intestine are the subjects of intense research. In this study, we investigated a model of intestinal inflammation driven by the intracellular apicomplexan parasite Eimeria falciformis. Although IFN-γ was the predominant cytokine during E. falciformis infection in wild-type mice, it was found to be dispensab...

Blastocystis is a genus of common single-celled intestinal parasitic protists with an unsettled role in human health and disease. Being a stable component of intestinal microbiota, once established, the Blastocystis parasite appears more common in healthy individuals than in patients with infectious, functional, or inflammatory bowel disease. Recent data suggest that the parasite is associated ...

Intestinal dwelling parasites have evolved closely with the complex intestinal microbiota of their host, but the significance of the host microbiota for metazoan pathogens and the role of their own intestinal microbiota are still not fully known. We have found that the parasitic nematode Trichuris muris acquired a distinct intestinal microbiota from its host, which was required for nematode fit...

Gross and histological lesions caused by an intestinal parasite were described in three capybaras. The parasites presented a mean length of 14 mm and width of 7 mm, were round to oval or piriform, reddish and pedunculated, and adhered strongly to the mucosa of the large intestine. The intestinal mucosa at the parasite attachment site presented loss of surface epithelium and most glands, with re...

An intestinal parasitic infestation is major public health problem in the world. It is estimated that 3.5 billion people are involved globally and 450 millions are suffering as a result of these infections, majority being children (WHO, 2000). The most important protozoan parasites are the Entamoeba histolytica and Giardia lamblia. Giardia lamblia (syn G. intestinalis, G.duodenalis) is one of t...

To assess the prevalence of intestinal parasitic infections in human immunodeficiency virus (HIV)-seropositive subjects, fecal samples were collected from 120 HIV-seropositive patients and were analyzed for various intestinal parasites. Thirty-six patients (30%) were found to harbor an intestinal parasite. Cryptosporidium parvum was the most common (10.8%), followed by Giardia lamblia (8.3%). C...

Cockroaches are claimed to be mechanical transmitters of disease causing microorganisms such as intestinal parasites, bacteria, fungi, and viruses. This study assessed the potential of the German cockroach Blattella germanica in the mechanical transmission of intestinal parasites of public health importance. A total of 2010 cockroaches were collected from 404 households in Jimma Town, southwest...
