| Abstract | ||
| One hundred-fifty random samples of fresh cream, whipped cream and kareish cheese (50 each) were examined for incidence of Aeromonas species. Aeromonas species were detected in 28%, 18% and 32% of examined samples respectively as regards every species Aeromonas hydrophila was detected in 16%,8% and 16% of examined samples respectively, Aeromonas sobria was detected in 18%, 10% and 24% of examined samples respectively and Aeromonas caviae was detected in 14%, 14% end 20% of examined samples respectively Regarding to haemolysin production,100%, 92.31% and 41.67% of A. hydrophila, A. sobria and A. caviae produced haemolysin while 90%,61.54% and 41.67% of A. hydrophila, A. sobria and A. caviae were proved to produce entero-toxin as judged by fluid accumulation in rabbit ileal loop.Concerning the production of spoilage enzymes, Aeromonas hydrophila was dominating other Aeromonas species for proteolytic and lipolytic activities compr-ising65% and 25% respectively. Regarding to antibiotic sensitivity against 9 antimicrobial agents A. hydrophila was 100% sensitive to chloramphe-nicol, tetracycline and neomycin while Aeromonas sobria was completely resistant to ampicillin, chloramphneicol and erythromycine and Aerom-onans caviae was completely resistant to ampicilin and nalidixic. | ||
