Abstract | ||
Fifty samples of fresh Clarias gariepinus fish were collected randomly fromdifferentmarketsatTantacity,Gharbiagovernorate.Thesesamples were examined for isolation and identification of psychrotrophic bact-eria, particulary Aeromonas species, the isolated strains of psychrotro-phic species were Acinetobacter8%,Aeromonas 56%,Alcaligens 12%, Chromobacterium10%, Psuedomonas 28% and Flavobacterium 6% . Further identification of Aeromonas species were recovered as Aerm-onas A.hydrophla, 30% A.pumctata 16% and A.salmonicida 10%. All Aeromonas speices were examined for their ability to produce lipolytic, proteolytic, hemolytic and Dnase activities in different percentages 78.6%, 71.4%, 82.1% and 67.9% , respectively. Concerning the antibiotic sensitivity of the isolated Aeromonas strains, they were sensitive to enrofloxacin, gentamycin, oxytetracycline, tetracycline and nalidixic acid on other hand, they have a high resistance to amoxi-cillin, ampicillin, pencillin, erythromycin, and lincospectin. The public health significance of isolated strains and recommended sanitary measures were discussed. | ||
