SUMMARYFive hundred and seventy-one camel sera collected after an epizootic of Rift Valley Fever were examined for antibody to the virus. Clinical disease had not been observed in cattle and sheep in the ecosystems shared with the camels. Positive sera with high titres of serum neutralizing antibody were found in 22% of camels at one of the seven sampling sites.
This study examined the ultrastructure of tissues from young broilers with an ascitic syndrome collected from a farm near Nairobi, Kenya which is located at an altitude of 1500 m. All organs (kidney, liver, heart, spleen and lungs) revealed more severe changes than those previously reported in age-matched birds during a low altitude study.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
