Detection and molecular epidemiology of ferlaviruses in farmed snakes with respiratory disease in Guangxi Province, China.

ABSTRACT: We screened 104 snakes with respiratory disease, collected from 52 snake farms in Guangxi Province, China, for pathogens. Ferlaviruses were detected in 70 of 104 lung samples by reverse-transcription PCR; 34 of 52 of the snake farms were positive for ferlaviruses. No reovirus, adenovirus, sunshine virus, or nidovirus was detected in any of the snakes. We obtained 96 bacterial isolates from snake organs, of which the most commonly isolated species were Salmonella (18) and Proteus (16). Sequence analysis, based on 27 partial RNA-dependent RNA polymerase gene (L) sequences, revealed that ferlaviruses from Guangxi and the known GenBank strains clustered together and formed 3 genogroups. The nucleotide and deduced amino acid homologies of ferlaviruses were 84.3-100% and 95.
