BACKGROUND The prevalence of multi-infections with helminthes, protozoans and Campylobacter spp. in Guatemalan children is a reflection of differences in the risk factors related to pathogen transmission. METHODOLOGY Two hundred and eighty-nine fecal samples were collected from children of the Guatemalan highlands and patterns of pathogen occurrences were(More)
In the course of studying Ia molecules from strain 2 and strain 13 guinea pig macrophages, with the intent of comparing them to B cell Ia molecules, it was observed that guinea pig alloserum prepared by cross-immunization of guinea pig lymphocyte Ag non-identical inbred guinea pigs immunoprecipitated not only conventional class I and class II molecules, but(More)
Demonstration of cryptosporidiosis in Mayan Indians living around Lake Atitlan provided an opportunity to correlate infection with abdominal pain and/or diarrhea in different age groups of children. 94 subjects experiencing abdominal pain and/or diarrhea, between the ages of 2 and 13 were studied in towns around Lake Atitlan, Guatemala, over a two-year(More)
We have identified a macrophage-specific molecule, termed gp98, which has a m.w. of 98,000, is encoded by a gene not linked to the guinea pig lymphocyte antigen complex, is highly immunogenic, and displays a serologic polymorphism among several inbred guinea pig strains. The gp98 molecule was biochemically analyzed to identify a basis for the serologically(More)
