Epidemiology of Aeromonas species isolated from different samples in Al-Diwanyiah province

Approximately 1.3 million infants under five years old perished from gastroenteritis associated with Aeromonas species as of 2008.Because of ability into stay at water of chlorinated when it forms biofilms, as well as their resistance to antibiotics and virulence toxins, Aeromonas species must be continuously screened for in food and diarrheagenic feces.50 samples of tap water, 50 samples of diarrheagenic feces, were randomly chosen from Diwaniyah city using standard protocol, and their Aeromonas species content was checked." The reported Aeromonas species was identifie by a conventional method and then confirm at PCR uses a 16S rRNA primer.Only 80 samples was contain the bacteria and then antibiotic test was doing against 7 antibiotics and was some antibiotics have resistant to samples and other was sensitive to samples .thehighest presence of isolates that belong to Aeromonas species was A hydrophilla in ratio (37.5%) while the lowest ratio was both species A trota (2.5%)andA jandaei (2.5%) the result of antibiotics test The results were as follows where high reistant percentage was of Gentamycin and Rifampin is 56.25% and 50% respectively ,whili the the high sensitive percentage of Erythromycin and meropenem was 53.75% and 42.5% respectively.whilithe intermediate isolates of antibiotics was Streptomycin about 50%.this means that Erythromycin ,Meropenem and Chloramphenicol more effective against this bacteria and can use for treatment.
