ABSTRACT.- Costa M.M., Peixoto R.M., Boijink C.L., Castagna L., Meurer F., & Vargas A.C. 2008. [Antimicrobial sensibility of bacterial isolates from jundiá (Rhamdia quelen).] Sensibilidade antimicrobiana de bactérias isoladas de jundiá (Rhamdia quelen). Pesquisa Veterinária Brasileira 28(10):477-480. Universidade Federal do Vale do São Francisco, Rua da Simpatia 179, Petrolina, PE 56304-440, Brazil. E-mail: mateus.costa@univasf.edu.br
Aiming the evaluation of sensitivity profiles of pathogen bacteria responsible for fish diseases, 51 bacterial isolates from Jundiá (Rhamdia quelen) belonging to the genus Acinetobacter spp. (8), Aeromonas spp. (15), Edwardsiella spp. (2), Enterobacter spp. (2), Klebsiella spp. (1), Plesiomonas spp. (5), Pseudomonas spp. (1), Staphylococcus spp. (11), and Vibrio spp. (6), were tested against antimicrobial agents used for treatment of bacterial fish diseases. All samples were processed at the Laboratory of Bacteriology, Department of Preventive Veterinary Medicine, UFSM. From 51 bacteria isolated from jundiá fishes (Rhamdia quelen) 51 (100%) were sensitive to gentamycin, 49 (96,08%) to sulphazotrin, 47(92,16%) to chloramphenicol, 43 (84,31%) to tetracylin, 43 (84,31%) to naldixic acid, 31 (60,78%) to nitrofurantoin, 22 (43,14%) to erytromycin, 22 (43,14%) to ampicillin, 15 (29,41%) spiramycin, 13 (25,50%) to cholystin, and 5 (3%) to penicillin G. With exception of an isolate of Staphylococcus spp., the bacteria analyzed in the present study were resistant to one or more antimicrobial agents tested. Knowledge of the sensitivity profile of bacteria involved in infectious processes in fish will allow rational antimicrobial treatment that will contribute to the control of fish diseases in Rhamdia quelen without causing great risks to public health and the environment. |
