Antibiotic and Herbal Sensitivity of Some Aeromonas sp. Isolates Collected from Diseased Carp Fishes

摘要: Studies were conducted to identify Aeromonas sp. isolates collected from disease affected carp fishes ( Cyprinus carpio and Labeo rohita ), their antibiotic sensitivity pattern 121 herb extracts. A total of 19 identified a 84 different through series physiological, morphological biochemical tests. Seven antibiotics viz., streptomycin, chloramphenicol, erythromycin, sulphamethoxazole, cephradine, oxytetracycline gentamycin tested by disc diffusion method where all the found sensitive erythromycin gentamycin. But, 78.95% resistant oxytetracycline. In addition, 5%, 11%, 16% exhibited resistance cephradine respectively. Twenty one percent showed multiple antibiotics. extracts evaluated for fish pathogenic isolates. Among these, 23 herbs possess antimicrobial activity. Leaf Eugenia caryophyllus , Spondias pinnata Terminalia chebula inhibit growth this study, also be several Thus, herbal treatment would promise greater viable solution effective disease.
