AbstractA total of 256 Salmonellastrains consisting of 29 Salmonellaserovars isolated from seafood of Cochin (India) were analyzed for resistance to antimicrobials commonly used in human and veterinary medicines as therapeutic agents. The 10 most predominant Salmonellaserovars in seafood were also characterized for presence of plasmids using the alkaline lysis method. Antimicrobial susceptibility studies highlighted a comparatively high resistance in Salmonellaisolates to sulfamethizol and carbenicillin, and moderate resistance to nalidixic acid and oxytetracycline. Nevertheless, antimicrobial resistance was not observed against ampicillin, ciprofloxacin, chloramphenicol, gentamicin, and kanamycin in different Salmonellaserovars. Fifty percent of the Salmonellaisolates, comprising 16 Salmonellaserovars, were resistant to sulfamethizol followed by 39% resistant to carbenicillin and 14% resistant to oxytetracycline. Multidrug resistance was detected in 39.4%, 14.4%, 12.1%, and 1.5% of Salmonellaisolates towards two drugs (sulfamethizol and carbenicillin), three drugs (sulfamethizol, carbenicillin, and oxytetracycline), four drugs (sulfamethizol, carbenicillin, oxytetracycline, and nalidixic acid), and five drugs (sulfamethizol, carbenicillin, oxytetracycline, nalidixic acid, and streptomycin), respectively. Plasmid profiling highlighted the presence of nine plasmid profiles in Salmonellaserovars and plasmids that were not detected in Salmonella entericasubsp. entericaWeltevreden, SalmonellaRissen, SalmonellaBareilly, SalmonellaIrumu, SalmonellaOhio, SalmonellaOslo, and SalmonellaTyphi isolated from seafood. |
