Insights into the sand fly saliva: Blood-feeding and immune interactions between sand flies, hosts, and Leishmania.

abstract：BACKGROUND:Venom recurrence or persistence in the circulation after antivenom treatment has been documented many times in viper envenoming. However, it has not been associated with clinical recurrence for many snakes, including Russell's viper (Daboia spp.). We compare the recovery of coagulopathy to the recurrence or ...
