Isolation and identification of four pathogenic bacterial strains from edible snake (Elaphe carinata and Ptyasmucosus) farms with pneumonia in China

This report describes an outbreak and treatment of pneumonia and enteritis in a snake farm with more than 3000 snakes containing Elaphe carinata (one-year-old) and Ptyas mucosus (three-month-old) seedlings in Huanggang, Hubei, China. Gentamicin was used once in the early stage as treatment, administ...

Description
Summary:This report describes an outbreak and treatment of pneumonia and enteritis in a snake farm with more than 3000 snakes containing Elaphe carinata (one-year-old) and Ptyas mucosus (three-month-old) seedlings in Huanggang, Hubei, China. Gentamicin was used once in the early stage as treatment, administered orally with water or feed by owners, but mortality increased. Lobar pneumonia was confirmed by dissection and histopathology in infected snakes. Four main pathogenic bacteria were isolated and identified with culture and 16S rRNA sequencing: Staphylococcus sciuri , Salmonella enteritis , Vagococcus fluvialis and Providencia vermicola . Drug susceptibility tests were performed, and amikacin, gentamicin and cefitriaxone were chosen accordingly. After two rounds of treatment, the clinical signs for Elaphe carinata were under control, and the mortality was close to 0% after treatment. However, treatments for Ptyas mucosus seedlings did not work well, potentially because of poor administration technique and weak body condition.
