Abstract A total of 256 strains consisting of 29 serovars 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 serovars in seafood were also characterized for presence of plasmids using the alkaline lysis method. Antimicrobial susceptibility studies highlighted a comparatively high resistance in isolates to sulfarnethizol 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 serovars. Fifty percent of the isolates, comprising 16 serovars, 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 isolates towards two drugs (sulfamethizol and carbenicillin), three drugs (sulfamethizol, carbenicill_and oxytetracycline), four drugs (sii I famethizol, carbenicillin, oxytetracycline, and nalidixic acid), and five drug_(sulfamethizol, carbenicillin, oxytetracycline, nalidixic acid, and streptomycin), respectively. Plasmid profiling highlighted profiles in Salmonella serovars and plasmids Salmonella subsp. enterica Weltevreden, Rissen, Bareilly, Irurnil, Salmonella Ohio, Oslo, and Typhi isolated from seafood.
