The '''predominant infection vector''' is through exposure to water harbouring ''Aeromonas sobria''. <ref>Joseph, S. W., O. P. Daily, W. S. Hunt, R. J. Seidler, D. A. Allen, and R. R. Colwell. 1979.

The most common form of disease is one where ''A.sobria'' pathogen adheres to the surface of the intestine causing painful diarrhea, also known as [http://en.wikipedia.org/wiki/Gastroenteritis gastroenteritis]. The enterotoxin activity of the [http://en.wikipedia.org/wiki/Hemolysin hemolysin] [http://en.wikipedia.org/wiki/Virulence_factor virulence factors] of ''A.sobria'' contributes to those symptoms. However, the mortality due to intestinal disease type of infection is low compared to the non-intestinal diseases caused by the ''A.sobria'' infection.

Once invaded the intestine epithelial cells, Aeromonas can reach any organ via the blood. Multiple virulence factor than promote their pathogenicity.
