Effects of Iranian Snakes Venom True Sea and Terrestrial Snakes on Some Bacterial Cultures
The antibacterial activities of eight snake crude venom (Macrovipera lebetina obtusa, Pseudocerastes persicus, Pseudocerastes urarachnoides, Echis carinatus sochureki, Gloydius halys caucasicus, Naja (naja) oxiana, and two species of true sea snakes Enhydrina schistose and Hydrophis cyanocinctus) were assessed against five important standard pathogenic bacterial strains (Escherichia coli, ...
متن کاملVenom yields from Australian and some other species of snakes.
The wet and dry venom yields for most Australian native dangerous snakes and a number of non-Australian species are presented. Snakes from the Pseudonaja genus yielded higher than previously published amounts and suggest reconsideration be given to increasing the volume of antivenom in each vial. Higher percentage solids were obtained from venoms from the 4 cobra species (Naja) and Pseudechis g...
متن کاملThe evolution of venom-delivery systems in snakes
The Colubroidea represents approximately 2300 of the 2700 species of living snakes and includes all venomous taxa. Although many morphological studies of colubroid snakes have been carried over the last hundred years, the phylogenetic relationships within this group are poorly known. In this study, components of the venom-delivery system (VDS) were examined within the context of two conflicting...
متن کاملExperimental studies of coral snake mimicry: do snakes mimic millipedes?
The prevalence of similarly ringed colour patterns in Neotropical snake species has stimulated heated controversy over the cause of this apparent convergence since it was first noted by Cope (1860) and Wallace (1870) in the last century. These ringed and banded species include venomous (neurotoxic) elapid coral snakes (Micrurus) and a number of mildly or non-venomous colubrid and anniliid snake...
متن کاملHow Do Nocturnal Snakes Select Diurnal Retreat Sites ?
Theoretical and empirical studies of habitat selection suggest that reptiles should use ‘‘fixed’’ structural features (perch diameter, vegetation) or light intensity (sun and shade) to select thermally suitable microhabitats. But how do nocturnal species select thermally suitable diurnal retreat sites at night in the absence of visual cues? To investigate this question, we studied habitat selec...
