Abstract

The current study assesses the resistance profile of Aeromonas spp. individuals isolated from tambaqui fish (Colossoma macropomum) grown in fish farms located in São Luís Metropolitan Region - MA. In total, 114 bacterial strains belonging to species Aeromonas spp. were used in the experiment. Antimicrobial resistance profile was defined based on using the disk diffusion method and 10 antimicrobials. Isolates were classified as susceptible, susceptible upon increased exposure and resistant to the assessed principles; phenotypes showing resistance to multiple tested drugs (MDR) were classified. Bacterial strains presented widespread resistance to penicillin; as well as high oxacillin-, cefepime-, cefadroxil- and azithromycin-resistance rates. Ampicillin associated with sulbactam, neomycin and ofloxacin were the antimicrobials recording the highest sensitivity rate; high frequency of isolates (34.21%) were categorized as MDR phenotypes. Antimicrobial resistance was observed in the herein assessed Aeromonas spp. isolates, despite the lack of antimicrobials registered in Brazil to be used for C. macropomum fish farming purposes.

Keywords: Aeromonadaceae, bacterial resistance, fish farming.
