Comprehensive proteomic profiling of adult Angiostrongylus costaricensis, a human parasitic nematode.

Angiostrongylus costaricensis is a nematode helminth that causes an intestinal acute inflammatory process known as abdominal angiostrongyliasis, which is a poorly understood human disease occurring in Latin America. Our aim was to study the proteomic profiles of adult parasites focusing on immunogenic proteins. Total cellular extracts from both genders showed similar 2-DE profiles, with 60% of all protein spots focused between pH 5-7 and presenting molecular masses from 20.

[Intestinal parasitic helminths in institutionalized dogs of Rio de Janeiro, Brazil].

The occurrence of intestinal parasitic helminths in dogs from a public institute of veterinary medicine in Rio de Janeiro was assessed. Samples of fresh feces were collected in March 2004 and analyzed by Willis and centrifugal-flotation in sucrose solution methods. Of 204 samples, 45.
