Aeromonassp. in freshwater fish and antimicrobial resistance: emerging pathogen

ABSTRACT: The bacteria Aeromonassp. are naturally reported in aquatic ecosystems and possess pathogenic potential, being considered as emerging pathogens humans animals. They also cause considerable losses fish farming and, through water, can contaminate numerous foods. This study quantified analyzed the antimicrobial resistance profile of fish. A total 72 samples two varieties (leather fish, Pseudoplatystomafasciatumx Leiariusmarmoratusand round Colossomamacropomumx Piaractusmesopotamicusand Piaractusbrachypomus) were purchased from types sources (fresh frozen) three commercial establishments (supermarket, market, fishmonger). 55 isolated Aeromonascultures evaluated for their by disc diffusion method. Upon quantification, count ranged 4.22 to 6.00 Log CFU/g; ten different species, including A. eucrenophila, hydrophila, caviae, media, jandaei, veroniibv. sobria, trota, schubertii, veronii, shigelloides, identified. Among isolates, 64.45% showed Ampicillin-sulbactam, 75% sensitive gentamicin ciprofloxacin. It was concluded that 100% contaminated Aeromonassp., which may present a risk consumer health since be etiological agents Foodborne Diseases. ampicillin multi-resistance classes antimicrobials, demonstrating problems with choosing an treatment any disease.
