It is important to identify the bacteria in snakes because they can cause disease; importantly, bacteria such as Stenotrophomonas maltophilia, Escherichia coli, Proteus vulgaris etc. could be pathogens especially in hospitalized, debilitated hosts, and immunocompromised patients. To analyze the distribution of snakes' bacteria in petting zoo, samples from 20 snakes were collected from 2002 to 2008. Nine bacteria species were isolated from both oral and cloaca while four and six species were identified only from oral and cloaca, respectively. Except for Actinobacter sp., all of the identified strains are opportunistic pathogens, and most of them can cause nosocomial infections in humans. Present results indicate that prevalence of various zoonotic bacterial strains in snakes could be involved in potential transfer of these bacteria into caretakers and other animals. Therefore, it needs to examine the antibiotic resistance of these pathogens to prevent outbreaks.

Reptiles are used for various purposes these days, including public exhibits, medicinal applications, and as laboratory animals. As the international exchange of reptiles has gradually increased, more people have had the opportunity to come in contact with these animals. Snakes typically live in the rhizosphere where various bacterial strains exist and as such they can lead to opportunistic human diseases. When snakes are encountered in veterinary medicine, it is necessary to monitor their microflora. Native microflora of reptiles imported from other countries has not yet been reported in Korea. In this study, oral and cloacae samples were collected from 18 Burmese pythons transported from Vietnam. The specimens were incubated at 37degrees C for 18 h to produce colony growth under aerobic condition and isolated colonies were then identified using a VITEK automated identification system. There were fourteen types of aerobic bacteria isolated from both oral and cloacae samples, nine from only oral specimens, and fifteen from only cloacae specimens. Most bacteria isolated were opportunistic pathogens of humans which therefore have the potential to induce disease in people. Based on the microflora and the prevalence of bacterial strains in snakes, quarantine procedures for reptiles transported internationally should be strengthened. Characterization of the microflora of reptiles with the potential to induce zoonosis should be performed in those used as laboratory animals and to prevent zoonotic outbreaks in the general population as well as among veterinarians.
