tailieunhanh - Bacteriological study of fish samples collected from different markets in some Egyptian governorates and antimicrobial sensitivity of isolates

A total of (80) samples of living diseased cultured Tilapia fish (Oreochromusniloticus), were collected from different fish farms in Egypt (Behera and Kafr El-Sheikh) which showed the clinical signs of loss of scales from some areas of the skin, excessive mucus all over the body surfaces with petechial haemorrhages over the dorsal musculature, large necrotic lesions extending all over the body and darkness of skin. | 2017 6 5 2765-2776 International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 6 Number 5 2017 pp. 2765-2776 Journal homepage http Original Research Article https Bacteriological Study of Fish Samples Collected from Different Markets in Some Egyptian Governorates and Antimicrobial Sensitivity of Isolates Elham I. Atwa Hafr Al Batin University College of Science and Arts - Al Khafji Biology Department Corresponding author ABSTRACT A total of 80 samples of living diseased cultured Tilapia fish Oreochromusniloticus were collected from different fish farms in Egypt Behera and Kafr El-Sheikh which showed the clinical signs of loss of scales from some areas of the skin excessive mucus all Keywords over the body surfaces with petechial haemorrhages over the dorsal musculature large necrotic lesions extending all over the body and darkness of skin. Differentiation and Haemorrhages characterization of various isolates was based on their growth characteristics on specific Fluorescens culture media biochemical and gram staining reactions . The following human pathogenic Norfloxacin bacteria were isolated Staph. aureus Staph. epidermidis Staph. Saprophytics Bacteria Streptococcus spp. E. coli Salmonella P. aeruginosa P. fluorescens and Fish Enterobacteriaceae from skin with the incidence of 10 25 Epidermidis 20 and respectively but from muscle with the incidence of Article Info 5 20 and respectively. On the other hand these bacteria isolated from intestine with the incidence Accepted 25 15 and respectively while from liver with incidence of 15 26 April 2017 15 35 25 and 15 respectively. In vitro sensitivity Available Online test indicated that the most prevalent bacteria isolated from examined fish samples were 10 May 2017 sensitive to enrofloxacin .
