Özet: Sturgeon farming in Turkey has increased in recent years. Fish are exposed to various diseases during the culturing period and these diseases can cause economic losses. In this study, a total of 37 strains isolated from diamond (Acipenser gueldenstaedtii) and siberian (Acipenser baerii) sturgeons till their average weights reach up to 3 kg were used to determine resistance profiles against antimicrobial substances and investigated their resistance genes. The most resistance to antibiotics in bacteria were found as sulphamethoxazole and ampicillin (97.3%). Moreover, the susceptibility of bacteria to the tested antibiotics for gentamicin, oxolinic acid, trimethoprim + sulfamethoxazole and florfenicol was determined as 86.5%, 59.5%, 45.9% and 40.5%, respectively. tetA ve tetB genes in the tested bacteria were detected as 10.8% and 21.6%, respectively. The most common genes were ampC and cmlA genes (24%) followed by sul3 and floR genes with a ratio of 19%. In this study, it can be said that there may be problems in the treatment of bacterial diseases in sturgeon farming because of being higher than 50% of the resistance levels of bacteria against antibiotics such as oxytetracycline, streptomycin, enrofloxacin and ampicillin.
