Abstract

Mugger crocodile is the only crocodilian existing in Iran. The present study was aimed to investigate the bacterial flora in the oral and cloacal cavities of wild Mugger crocodiles in Negour protected area, Iran. Twenty-two captured crocodiles were isolated and the molecular characterization of their oral and cloacal bacterial flora was performed. We recovered 10 bacterial species from the oral samples and 6 bacterial species from the cloacal samples. The most common bacteria in oral samples were Burkholderia contaminans and Lactococcus garvieae whereas in the cloacal samples, it was Lactococcus lactis. It is likely that the isolated bacteria would pose a threat to both crocodiles’ and humans’ health. They can threat crocodiles during stressful conditions while humans would be susceptible if they are bitten by crocodiles, consume their meat, or spend time near their natural environment. This study provides useful information on bacterial diversity carried by C. palustris in Iran which could help us select the most appropriate antibacterials when dealing with intoxication or infections caused by crocodiles’ meat or bites.
