The Current Antimicrobial Status of the Major Bacterial Pathogens in Rainbow Trout
Abstract
Antimicrobial resistance is a global threat to several industries, in addition to public health. The misuse of antibiotics in aquaculture leads to the development of resistance and limits the effects of treatment. It is important to determine antimicrobial resistance and proper doses to decide on optimum treatment strategies to avoid excessive antibiotic use. In this study, the antimicrobial resistance of three important bacterial fish pathogens (Lactococcus garvieae, Vibrio anguillarum, and Yersinia ruckeri) was determined to antibiotics used mainly in rainbow trout farms. L.garvieae strains showed resistance to most antimicrobial agents, although V.anguillarum and Y.ruckeri strains were determined resistant to clindamycin, ampicillin, and penicillin G. The MIC values of the pathogens were determined by E-test strips which provide rapid and quantitative results for selected chemotherapeutics. This article provides valuable information on the antimicrobial resistance of the most important pathogenic organisms on rainbow trout farms. The results of this study will be representative of the effective treatment and preventive misuse of antibiotics.
