متن کاملNormal oral bacterial flora from some southern African snakes.
Eighteen snakes representing 11 species were subject to mouth swabbing on 58 occasions. Of these swabs, 52.2% were positive for bacteria. A total of 92 bacterial isolates were cultured, representing 30 species of which 81.5% were Enterobacteriaceae, 16.3% gram positive cocci, and 2.2% anaerobes. Swabs from non-venomous snakes were more commonly bacteriologically sterile than those from venomous...
