| Summary: | Cloacal swabs from 74 healthy reptiles at Ljubljana Zoo were examined for the presence of salmonellae. Thirty nine reptiles underwent at least one antimicrobial treatment 24 - 48 months before sample collection. The identification of salmonellae was performed by matrix-assisted laser desorption ionization time-of-flight mass spectrometry and positive strains were serotyped. Salmonellae were found in 29.7% of all reptiles investigated, in 55.6% of reptiles kept with regularly direct contact with zoo visitors, and in 26.2% of reptiles kept strictly in terraria. The isolation prevalence was 38.6%, 18.2% and 12.5% in snakes, lizards and chelonians, respectively. Salmonella enterica subspecies enterica was the most common (63.6%) followed by subspecies diarizone (31.8%) and subspecies arizonae (4.5%). The serotypes Infantis and Uzaramo were detected in 27.3% and 36.4% of Salmonella positive samples, respectively. Resistance to antimicrobial agents was found in 9% of strains. A high percentage (63.6%) of Salmonella positive reptiles at Ljubljana Zoo shed serotypes that are known to be causative agents of human salmonellosis. This is the first documented isolation of serotype 57:k:e,n,x,z15 from captive reptiles.
