title: Production and evaluation of specific antisera against sera of various vertebrate species for identification of bloodmeals of Glossina morsitans centralis.
abstract: Specific antisera against sera of 46 species of vertebrates were prepared. The antisera to 21 Bovidae species were raised in goats except the antiserum to goat serum which was raised in sheep. The antisera to 3 Suidae species were produced either in domestic pigs or warthogs, while antisera to most of the other vertebrate species were raised in rabbits. The antisera were used in an enzyme-linked immunosorbent assay (ELISA) to identify the source of bloodmeals ingested by teneral and non-teneral tsetse at different time intervals after feeding. The bloodmeal donors were identifiable in 100% of the teneral tsetse up to 40 h post-feeding and in 87.5% in those tested up to 74 h post-feeding. Non-teneral tsetse digested the species-distinguishing bloodmeal components faster than the tenerals. Bloodmeals could be identified in 100% non-tenerals at 20 h post-feeding but only 67.5% and 50% of the bloodmeals could be identified 40 h and 74 h post-feeding, respectively. The antisera were also able to identify mixed bloodmeals from closely related species.
