Abstract: (541 Views) |
The bacterium Yersinia ruckeri is the causative agent of yersiniosis or red mouth disease, which leads to significant economic losses in aquaculture, especially salmon, worldwide. An infectious disease that leads to a septicemic condition with the condition of the body surface and internal organs. Despite this disease, investigation and its effect on this disease was studied in rainbow trout. This study was conducted on 180 pieces of rainbow salmon randomly weighing (25±2 gr), which were exposed to Y. ruckeri (5% and 10% LC50) for 30 days. Accepts. Results The results obtained with the increase in final weight, growth rate, alanine aminotransferase enzyme, high and low lipoprotein, total immunoglobulin, glutathione peroxidase of rainbow trout decreased and on the other hand with the increase of the drug, aspartate aminotransferase enzyme, total oxidant and Malondialdehyde increased so that there was a significant difference between the control group treated with 5% and 10% LD5 of Y. ruckeri bacteria. Based on the results of this research, the density of bacteria has a negative effect on most of the measured indicators.
