MICROBIOTA BACTERIANA COM POTENCIAL PATOGÊNICO EM PACAMÃ E PERFIL DE SENSIBILIDADE A ANTIMICROBIANO

Abstract

In aquaculture, infections caused by bacteria are factors that cause damage. The purpose of this study was to identify bacteria with pathogenic potential in pacamã (Lophiosilurus alexandri) of São Francisco Valley. One hundred and fifteen animals were used for sampling from gills, kidneys, external lesions and eggs. The samples were streaked in Trypticase soy agar. The biochemical and antimicrobial susceptibility profiles were determined. The bacterial species identified were A.hydrophila, A. salmonicida, A. media, Acinetobacter spp., P. alcaligenes, E. aerogenes, E. agglomerans, K. oxytoca, K. pneumoniae, P.shigelloides, V. parahaemo- lyticus, V. metschnikovii and S. sannei. The sensitivity to antimicrobial was 85% to norfloxacin, 79% to ceftri- axone, 78% to enrofloxacin, 68% to sulfazothrim, 60% to nitrofurantoin, 59% to tetracycline, 55% to nalidixic acid, 49% to streptomycin, 45% to erythromycin, 32% to neomycin, 7% to ampicillin and 3% to lincomycin. Multiple resistance was observed to all isolates analyzed. Considering the occurrence of pathogenic bacteria in pacamã and its resistance to antimicrobial drugs, security measures should be adopted during antimicrobialther- apy, with the use of antibiotics that did not show resistance strains or trying natural products as an alternative to antibiotics, ensuring protection of human and animal health, as well as the environment.
