Aeromonas hydrophila is a species of bacterium that is present in all freshwater environments and in brackish water.
Aeromonas species are associated with gastroenteritis and with wound infections, particularly wounds incurred in outdoor settings.
On May 1, 1988, isolates of Aeromonas became reportable in California, the first state to mandate reporting of isolates of and infections with these organisms.
Aeromonas was cultured from 2,848 diarrheic stool specimens submitted to a Los Angeles, California, hospital in the early 1980s and 80 (2.8%) were positive (20).
Aeromonas was not detected in any of the fecal specimens, even though 50% of water samples drawn weekly from the drinking water distribution mains serving the study participants were Aeromonas-positive (23).
Aeromonas isolates from stool and drinking water have been linked by biotyping (31) and whole-cell protein fingerprinting (25), but the discriminatory power of these methods with Aeromonas is questionable (28,30).
