| Abstract Background: Endogenous phospholipase A2 inhibitors from snake blood (sbPLIs) have been isolated from several species around the world, with the primary function of self-protection against the action of toxic phospholipases A2. In American snakes, sbPLIs were solely described in pit vipers, in which the natural protection role is justified. In this study, we described a sbPLI in Boa constrictor (popularly known as jiboia), a non-venomous snake species from America. Methods: PLA2 inhibitory activity was tested in the blood plasma of B. constrictor using C. d. terrificus venom as the enzyme source. Antibodies developed against CNF, a sbγPLI from Crotalus durissus terrificus, were used to investigate the presence of homologues in the blood plasma... |

| Predation on bats by snakes is relatively infrequently reported in the literature, though it may actually not be an uncommon phenomenon, since bat colonies represent a potential concentration of food for many medium-sized or large snakes. Herein we describe four events of bat predation by snakes and present a review of predation records of snakes on bats in the Neotropics compiled from the literature. A total of 20 species of snakes have been recorded so far as predators of bats in the New World tropics, with boiids being represented by the greatest number of cases. Due to the semi-arboreal habits of most of its species, their large size and their usual preference for mammalian prey, the Boiidae are probably the main reptilian predators of bats in the... |
