Abstract

Fish are, as well as other groups of animals, susceptible to bacterial infections, especially under stressfull conditions. The disease may present itself sistemically or be constrained to the outer surfaces such as gills or the skin. Many changes can be observed concerning the diseased individual, physiological or behavioral. Representatives of over 25 families of bacteria have been linked to fish diseases including the genus Pseudomonas. So far, there have been six species identified as causative agents of fish disease: Pseudomonas anguilliseptica, Pseudomonas chlororaphis, Pseudomonas fluorescens, Pseudomonas plecoglossicida, Pseudomonas pseudoalcaligenes te Pseudomonas putida. They are ubiquitous in the environment and are mainly thought of as oportunistic or weak primary pathogens. These bacteria cause mostly haemorrhages in a number of organs, the accumulation of ascitic fluid in the abdomen as well as lesions and ulcers. Due to the losses in aquaculture Pseudomonas anguilliseptica is economically most significant.
