The present study was undertaken to elucidate some aspects about the nature of the spermatozoon ultrastructure of Crotallus durissus using cytochemical methods. We also provide for the first time the ultrastructural description of this species spermatozoon. Cytochemical studies of spermatozoa have not been performed so far in the Serpentes, and species spermatozoon may prove helpful to better u...

Rhabdias filicaudalis n. sp. (Nematoda: Rhabdiasidae) from the lung of Spilotes pullatus (Serpentes: Colubridae) is described. The host snake was captured in the municipality of Avaré, São Paulo State, Brazil. Rhabdias filicaudalis n. sp. differs from all other species by the combination of the following characters: straight body, truncated anterior end, six weakly developed lips arranged in tw...

Transmission of specific immunoglobulins from mothers to their offspring via the egg is a common phenomenon in egg-laying vertebrates but the occurrence of this phenomenon in reptiles, especially in colubrid snakes, has not been proven until recently. Thus, the essential biochemical characteristics of antibodies deposited in eggs of Elaphe guttata (Colubridae, Serpentes) were studied after isol...

Reptiles can harbor pathogenic microorganisms asymptomatically and serve as potential reservoirs of infection for humans, domestic animals, and other reptiles. Infectious diseases are also problematic for free-ranging reptile populations and are an important consideration in reptile reintroduction and translocation projects. There have been limited serologic studies of free-ranging reptiles for...

We describe two new species of Tropidodipsas related to the T. fasciata group as defined by Kofron (1987), and provide morphological molecular data support novelty both species. A partial phylogeny Mexican snail-eating snakes (Serpentes, Dipsadidae) is presented, we discuss evolutionary relationships supported our results. analyze specific described herein with their closest relatives. present ...
