Bacteria Aeromonas

Amphibians. Immunosuppression has been shown to occur during metamorphosis in several amphibians, and appears to be hormonally regulated. The disappearance of 11 populations of toad from Colorado was associated with immune suppression, and frog mortalities have been associated with infection by a commonly occurring bacteria, Aeromonas hydrophila the cause of the immunosuppression in these animals has not been elucidated.

Studies on S-layers present on the cell envelopes of a great variety of pathogenic organisms [100] revealed that these crystalhne arrays can represent important virulence factors. Most detailed studies have been performed on the fish pathogenic bacteria Aeromonas salmonicida and Aeromonas hydrophila [102] and the human pathogen Campylobacter fetus uh p. fetus [103] and Bacillus anthracis [104]. For example, whole-cell preparations or partially purified cell products are currently used as attenuated vaccines against various fish pathogens [102,105].

Investigations of pure cultures of bacteria clearly show the existence of a threshold concentration for the carbon source below which replication does not occur. This value is about 18 pg/1 for Escherichia coli and Pseudomonas sp. growing on glucose, 180 pg/1 for Aeromonas hydrophila growing on starch,... 

Soil is a natural habitat for several human pathogens such as B. cereus, Cl. botulinum, and Cl. perfringens, L. monocytogenes, and Aeromonas (Waage et al., 1999). The aforementioned bacteria have adapted to survival in soil with spores persisting for indefinite periods.
