The IgE response has been associated with both allergic reactions and immunity to metazoan parasites. Recently, we hypothesized that all environmental allergens bear structural homology to IgE-binding antigens from metazoan parasites and that this homology defines the relatively small number of protein families containing allergenic targets. In this study, known allergen structures (Pfam domain...

Américo Vespucio s/n, 41092 Sevilla, Spain e-mail: [email protected] Plumage coloration plays an important role in intra and inter-sexual competition in birds. Many of the yellow, orange, or red colors present in birds are carotenoid dependent. Carotenoids cannot be synthetized de novo by birds and consequently should be obta...

AIM The aim of the present study is to assess the prevalence of intestinal and haemoprotozoan parasites of small ruminants (Sheep and Goats) in North Western part of Tamil Nadu, India. MATERIALS AND METHODS A total of 630 faecal samples (251-sheep, 379-goats) and 554 blood smears (242-sheep, 312-goats) were examined, for the presence of eggs of intestinal and haemoprotozoan parasites, respect...

One of the most unexpected insights that followed from the completion of the human genome a decade ago was that more than half of our DNA is derived from transposable elements (TEs). Due to advances in high throughput sequencing technologies it is now clear that TEs comprise the largest molecular class within most metazoan genomes. TEs, once categorised as "junk DNA", are now known to influence...

background: intestinal protozoa transmitted by food are the most common opportunistic parasites among the hiv+/aids patients. as, there is no report about prevalence of food-borne intestinal parasites in such patients in yazd, so this study was performed to determine the prevalence of intestinal protozoa in the hiv+/aids patients in comparison with hiv- individuals. methods: a case-control stud...

Dyspepsia and intestinal worm infestation are both common clinical conditions in a developing country like Kenya and thus this study was designed to look at the correlation between the two in a referral gastroenterology clinic at Kenyatta National Hospital. One hundred and twenty five patients with dyspepsia had their stool, duodenal aspirate and duodenal biopsy analysed for evidence of intesti...

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 (...

Intestinal parasitic infections (IPI) are one of the most prevalent infections in humans residing in developing countries and its burden is high among school aged children. This cross-sectional study was conducted to determine the prevalence of intestinal parasitic infection and types of intestinal parasites in rural public school children of Nepal. It included students from Nursery to Class X ...

OBJECTIVE The aim of this study was identification of the parasites of the common carp from Tahtalı Dam Lake. METHODS The fish were transported live to the laboratory. They were investigated for ectoparasites and endoparasites. The parasite specimens were fixed and identified. RESULTS During the study, 47 common carp were caught monthly and 3 species of metazoan parasites were found: Dactyl...
