In the present study, 150 pieces of marine shrimp “Fenneropenaeus indicus
” were collected during heavy mortalities attack at El-Deba triangle area, Damietta governorates, Egypt. Samples were collected for clinical, postmortem examination and different microbiological assessments for determination of the causes of mortality. Bacterial identification results revealed infection with Vibrio parahaemolyticus.
In addition, studying the effect of bacterial infection on the oxidative stress biomarkers in the infected shrimp revealed a significant increase in SOD activity in comparison with the control group in gills, hepatopancreas, and musculature. The activity of GP x significantly increased in the infected group, Where GP x activity in gills, hepatopancreas and musculature revealed a 3.25, 1.64- and 2.18-fold increases when compared with the control group, respectively. Similarly, levels of lipid peroxidation (MDA) showed a significant increase in Vibriosis infected groups in comparison with the control group by 2.1, 1.6 and 2.1 folds for gills, hepatopancreas, and musculature, respectively. The total protein, hemolytic count and lysozyme activity of shrimps exposed to Vibriosis showed a significant decrease compared to control while phenol oxidase activity increased. There was a non-significant difference between infected and the apparently healthy shrimps regarding respiratory burst. There was a significant increase in glucose concentration in shrimp group exposed to Vibriosis in comparison with control healthy shrimps. (P≤0.05). Regarding antibiotic sensitivity test, Vibrio parahaemolyticus
isolate was sensitive to Ciprofloxacin and Novobiocin but it was resistant to Amoxicillin and Colistin sulphate.Pages: 110-115 | 453 Views 22 DownloadsDownload Full Article:
