Abstract |
Based on the requirements of oxygen for growth and viability, bacteria are divided into Aerobes, Anaerobes, facultative anaerobes and Microaerophilic (vide infra). Those bacteria which can grow only in the absence of oxygen are termed 'anaerobes'. Anaerobes bacteria which are pathogenic are found associated with fish, fishery products and fishery environments. Examples are Clostridium botulinum, Clostridium perfringens (also called C. welchii), Campylobacter jejuni and Campylobacter coli. |
