Abstract

Some bacteria play a considerable role in the pathology of fish, sometimes. They may infect with one or more fish species, which makes them true pathogens, capable of infecting most healthy animals. However, only opportunistic pathogens whose infectivity is expressed by a decline in the fish condition and of its natural defenses, are linked to disturbances of the environment or livestock practices, creating the most favorable context for the development of bacterial pathologies.
