Microbiological analysis of skin lesions of cod

Since the middle of the 1980s, severe skin disorders have been observed in Baltic cod ( A total of 1,381 cod were caught during two voyages of the Baltica research vessel in the Polish exclusive economic zone of the southern Baltic Sea. After an examination which found lesions in 164 of the fish, a microbiological analysis was performed to isolate bacteria from them. The collected strains were phenotyped and genotyped, and their antimicrobial resistance was analysed by minimum inhibitory concentration (MIC) techniques. Bacteriological examinations provided 850 isolates. The dominant microorganisms were mesophilic Most of the collected bacteria were opportunistic pathogens for fish, widespread in the aquatic environment, and potentially threatening to humans.
