Unlike acute diarrhea, the role of pathogens in persistent diarrhea in children in Nepal is unclear. Protozoal parasites are suspected to be a major cause. The study was carried out to find the association between protozoal agents and persistent diarrhea in children below age 5 years from western Nepal. Stool samples were collected from 253 children with persistent diarrhea, from 155 children w...

© 2005 The Medicine Publishing Company Ltd 50 MEDICINE 33:8 Different species of the protozoan Trypanosoma are of similar appearance (Figure 1), and all are termed ‘kinetoplastids’ because they move using a flagellum that obtains energy from a mitochondrion called a plastid. However, trypanosomes also differ in many ways, including aspects of their molecular and cellular biology, their transmis...

The case definition of AIDS encompasses a spectrum of infections and malignancies, labelled as opportunistic infections. In recent years, numerous studies have outlined the emergence of opportunistic gastrointestinal protozoa that have caused diarrhoeal illness among HIV – AIDS patients. Purpose of present study was to determine the prevalence of opportunistic intestinal protozoal parasites in ...

Several interferon inducers (Newcastle disease virus, statolon, and poly rI:poly rC) as well as exogenous mouse interferon protect mice from sporozoite-induced Plasmodium berghei malaria, as long as they are administered before the end of the preerythrocytic phase of development of the parasite. The protective effect of the interferon inducers was related to their interferon-inducing effect; th...

Protozoal infections, though endemic to certain regions, can be seen all around the world, because of the increase in travel and migration. In addition, immunosuppression associated with various conditions, particularly with HIV infection, favors the occurrence of more severe manifestations and failure to respond to treatments. The CNS may be the only affected system; when not, it is often the ...
