Giardia, a protozoan parasite, resides in the small intestine in man. This parasite damages the mucosal intestinal surface and in severe cases produces malabsorption and it may also affect mineral absorption, especially zinc. In this study a total of 118 infested and 43 non-infested persons as a control group were selected. From each patient a 5 ml blood sample was obtained. The serum was ...

The diagnosis of Chagas disease in humans is generally limited to the detection of specific antibodies. Detection of T. cruzi antigens in urine has been reported previously, but is not used in the diagnosis. In this study, soluble T. cruzi antigens and DNA were detected in urine samples and were associated with kidney injury and systemic detection of the parasite. We used 72 guinea pigs infecte...

background: we investigated the variations of heamathologic and biochemical parameters with different parasitic burdens and the correlation between fecal egg counts and fluke number in livers of sheep naturally infected with dicrocoelium dendriticum . methods: in order to detect excretion of d. dendriticum eggs, fecal samples from 120 sheep of different age groups were collected individually at...

Dirofilariaimmitis, which is otherwise known as heartworm, is an important parasite in dogs and other carnivores. It lives in the right ventricle of the heart, the pulmonary artery and the posterior vena cava, and its microfilaria can be found in the peripheral circulation. This is the first report of Dirofilariaimmitis infection in stray dogs in Khuzestan, a province in South-Western Iran. Blo...

BACKGROUND Sub-Saharan African countries utilize whole blood (WB) to treat severe anemia secondary to severe blood loss or malaria on an emergency basis. In many areas with high prevalence of transfusion-transmissible agents, blood safety measures are insufficient. Pathogen reduction technology applied to WB might considerably improve blood safety. METHODS Whole blood from 40 different donors...

Abstract Host–parasite interactions include effects on both proximate and ultimate levels: parasite infections affect individual’s fitness play a significant role in shaping the life history of host species. Global environmental changes as well shifts abiotic factors might impact dynamics parasite–host interactions, especially Arctic regions, where climate is changing at an alarming rate. With ...
