The composition of Naja naja venom samples from three districts of West Bengal, India.
The variation in the composition of Naja naja venoms from three neighbouring districts of West Bengal, eastern India and the corresponding differences in the severity of pathogenesis due to venom composition variation are reported. These venom samples differ with respect to chromatographic elution profile and enzyme activity associated with each fraction. Presence of higher quantities of basic phospholipase and plasma protein hydrolase in the venom samples of Burdwan and Purulia make them more toxic than Midnapur venom sample. A polyvalent antivenom manufactured in western India was hardly effective in neutralizing the pathobiological manifestation of the venom samples from eastern India.
