Burmese Python Distribution in China Re-examined

Dave and Tracy Barker have published an updated summary of the distribution of bivittatus in China. They examine the distribution by province and analyze the known records for each. The most eastern record occurs at Naping in Fujian Province. It has also been recently reported from The Kimmen Archipelago on Queymoy Island. They found no records of the species in Guangxi, but note it is widely reported in the literature to be present. One record of a specimen from Jiangxi based on the literature appears to be based upon a visual sighting and a shed skin. P. bivittatus appears to be present in extreme southern Yunnan (on the Vietnam border) as well as extreme western Yunnan, avoiding the Shan Plateau. The authors consider the presence of bivittatus in Sichuan Province problematic. Both specimens were associated with urban areas and could represent human introduction.

Viruses in Captive Boids and Pythonids

A recently published study from Germany examined 100 apparently healthy booid snakes for the presence of paramyxoviruses (PMVs), and tested blood samples for antibodies against PMVs, adenoviruses and reovirus and for inclusion bodies that would indicate the presence of inclusion body disease (IBD). Nine snakes tested positive for PMVs and six snakes tested positive for IBD antibodies. Antibodies against PMV were found in one snake and two snakes had antibodies against an adenovirus.The blood samples were obtained from 14 private and zoo collections in Germany and taken only from snakes that showed no signs of disease. Snake owners answered detailed questionnaires about the snakes origins, diet, and husbandry. The authors suggest that the risk of spreading an infection in a collection is considerably greater that previously thought from snakes that appear healthy.
