Coproscopic examinations of mouflons Ovis aries musimon from four forest districts of Lower Silesia performed in spring and autumn from 2012 to 2014 demonstrated the presence of pulmonary nematodes and intestinal parasites, including coccidia of the genus Eimeria. Prevalence of pulmonary nematodes (mainly Muellerius capillaris) amounted to 69.78%, intestinal nematodes--56.11% and coccidia of th...

Infection with gastrointestinal helminths generates a dominant type 2 response among both adaptive (Th2) and innate (macrophage, eosinophil, and innate lymphoid) immune cell types. Two additional innate cell types, CD11c(high) dendritic cells (DCs) and basophils, have been implicated in the genesis of type 2 immunity. Investigating the type 2 response to intestinal nematode parasites, including...

In order to investigate the status of intestinal helminthic infections in Cambodia, epidemiological surveys were carried out on a national scale, including 19 provinces. A total of 32,201 fecal samples were collected from schoolchildren and adults between 2006 and 2011 and examined once by the Kato-Katz thick smear technique. The overall egg positive rate of intestinal helminths was 26.2%. The ...

Intestinal parasitic infections are among the most common infections worldwide and these infections tend to be higher in schoolchildren than other members of the community. Therefore, the aim of this study is to determine infection prevalence and associated risk factors of intestinal helminths among schoolchildren in Dawro Zone, Southern Ethiopia. A cross-sectional parasitological study was con...

This study was carried out to determine the role of non-biting cyclorrhaphan flies as carriers of human intestinal parasites at Woreta, northwestern Ethiopia. In total, 6530 flies were collected from four breeding sites and then examined for human intestinal parasites, mainly using the formol-ether concentration method. Fly species identified were Musca domestica (32.9%), Chrysomya rufifacies (...

The presence of intestinal helminths can down-regulate the immune response required to control mycobacterial infection. BALB/c mice infected with Mycobacterium bovis following an infection with the intestinal helminth Strongyloides venezuelensis showed reduced interleukin-17A production by lung cells and increased bacterial burden. Also, small granulomas and a high accumulation of cells express...

Food-handlers (n = 1500) attending the public health laboratory in Khartoum, Sudan, for annual check-ups were screened for intestinal parasites by 3 different techniques (direct faecal examination, formol-ether concentration and floatation) to evaluate the adequacy of annual screening. Results showed that 29.4% of food-handlers were harbouring intestinal protozoa in stool samples: Entamoeba col...

A survey of intestinal helminths was undertaken in riparian people in Xieng Khouang Province, Lao PDR. Fecal specimens were collected from 643 people (289 males and 354 females) residing in 4 districts (Nonghet, Kham, Phoukout, and Pek) and were examined by the Kato-Katz technique. The overall helminth egg positive rate was 41.2%, and hookworms revealed the highest prevalence (32.7%) followed b...

Abattoir survey was carried out to determine the prevalence of gastrointestinal helminths and the seasonal fluctuations in intestinal worm burdens and faecal worm egg counts of camel in Khorasan Razavi province in the northeast of Iran. A total of 306 dromedaries (Camelus dromedarius) in the Mashhad abattoir, in the northeast of Iran and the capital of Khorasanprovince were examined between Oct...

In most natural environments, the large majority of mammals harbour parasitic helminths that often live as adults within the intestine for prolonged periods (1-2 years). Although these organisms have been eradicated to a large extent within westernized human populations, those living within rural areas of developing countries continue to suffer from high infection rates. Indeed, recent estimate...
