Human Onchocerciasis, caused by infection the filarial nematode Onchocerca volvulus , is a neglected public health disease that affects millions of people in endemic regions sub-Saharan Africa and Latin America. It also called river blindness because Blackflies transmit breeds rapidly flowing fresh water streams rivers. This review features state-of-the-art data on parasite, its endobacteria Wo...

the purpose of this study was to investigate the status and epidemiology of intestinal parasites in iran. the information was driven from an extensive health survey which was done by the ministry of health and medical education, deputy of research affairs in 1990-92. sampling fraction was 1 per 1000 of individuals aged between 2 and 69, the sampling method was cluster sampling and each cluster ...

The co-evolution between hosts and parasites involves huge reciprocal selective pressures on both protagonists. However, relatively few reports have evaluated the impact of these reciprocal pressures on the molecular determinants at the core of the relevant interaction, such as the factors influencing parasitic virulence and host resistance. Here, we address this question in a host-parasite mod...

Behavioural adaptations of hosts to their parasites form an important component of the evolutionary dynamics of host-parasite interactions. As mushroom-feeding Drosophila can tolerate deadly mycotoxins, but their Howardula nematode parasites cannot, we asked how consuming the potent mycotoxin α-amanitin has affected this host-parasite interaction. We used the fly D. putrida and its parasite H. ...
