Study of Exotoxin Production Ability of Aeromonas species Isolated from Children Diarrhea in Mosul

Diarrhoeal stool samples of (850) infants and children under six years of age were examined. Those children were hosted in Ibn-Al-Athir's Hospital and Al-Salam Hospital in the city of Mosul in order to investigate the existence of Aeromonas by using microscopic, cultural and biochemical characteristics.
Three species of Aeromonas were detected in (21) children, thats (2.47%), arranged as follows: Aeromonas sobria (71.42%), Aeromonas hydrophila (19.05%), Aeromonas caviae (9.52%).
Aeromonas species possess various virulence factors such as toxin production for it has been found by suckling infants mouse assay that the A. sobria and A. hydrophila have a marked ability to produce toxins and that A. hydrophila is much more pathogenic (0.083-0.10) than A. sobria (0.083-0.096). A. caviae was incapable of toxin producing (0.075-0.077).
