  • Description: A total of 115 desiccated food samples, including agricultural and marine products, were investigated for the presence of . species were characterized with biochemical tests. Antibiotic resistance was assessed with the disk diffusion method, and the molecular subtypes of isolates were identified using an automated repetitive sequence‐based PCR (rep‐PCR) system. A total of 18 (15.7%) strains were isolated from 115 desiccated food products. Fifteen isolates were (13%), followed by 2 (1.7%), and 1 (0.9%). The most common antibiotic resistance of observed was against cephalothin (77.8%) followed by ampicillin (5.6%). With exception of 2 strains, all strains isolated from different sources were successfully differentiated by using the automated rep‐PCR system, indicating that it can be used for the purpose of contamination or outbreak source tracking of the bacteria.
