Abstract

A total of 74 water samples (35 canal water and 39 chlorinated tap water), 49 feed samples (22 Meat meal and 27 fish meal) and 49 faecal samples from diarrhoeic animals (24 from sheep and 25 from goats) were examined for Aeromonas Species. The highest incidence of isolation was Found in fresh canal water samples 40%, (14 out Of 35 samples) and in chlorinated water samples 23.1% (9 out of 39 samples)..The isolation of Aeromonas species from feed samples (meat and fish Meals) was more or less similar (22.85% and 22.0% respectively). Faeces from diarrhoeic Sheep and goats revealed the isolation of Aeromonas species in 16.7% and 20% respectively. Aeromonas hydrophila was most dominant and was Isolated from all different samples 65.1% of all Isolates (28 out of 43 isolates). Whereas Aeromonas sobria and Aeromonas caviae were isolated in Much lower rates 20.1% (9 isolates) and 14% (6 Sin production, enterotoxigenicity as well as cytoToxigenicity were expressed by A. hydrophila and A.Sobria more significantly (P<0.05) than A. cavIae. Most of the A. hydrophila and A. sobria isolates were enterotoxigenic (82.1% and 88.9% reSpectively) and could grow at 43°C and produce high haemolysin titers (1/128-1/1024). Essential Oils (clove coriander and peppermint) induced inhibitory effect on the growth of Aeromonas isolates. Clove oil had MIC of 500µg/ml, whereas Coriander and peppermint oils had 1,250µg/ml And 12,500µg/ml respectively. There was no difference in the antibiogram of A. hydrophila, A. Sobria and A. caviae. Most strains were found Sensitive to gentamicin, kanamycin and chloramphenicol and resistant to penicillin, ampicillin, Cephalosporine, novobiocin and bacitracin.
