| dc.description | In fish challenge tests, there is no standardization in the concentration and analysis period of parameters. This study investigates the immunomodulatory and cytotoxic effects of A. hydrophila dose and post- immunostimulation periods on Nile tilapia. Four level of bacterial doses (1⁄2, 1⁄4, 1⁄8, and 0 LD50) were administered, and immune parameters, hematological data, and erythrocyte abnormalities were analyzed at 3, 7, 10, and 14 days post-infection (dpi). The highest respiratory burst, total globulins, and lysozyme activity were detected at 7 dpi. Considering the bacteria doses, the lysozyme activity was higher in the 1⁄8 LD50 and 1⁄4 LD50 of A. hydrophila. Erythrocytes, hematocrit, hemoglobin, leukocytes, lymphocytes, neutrophils, and monocytes counts remained unchanged. Ten days post-injection, the control group exhibited reduced abnormalities, showing a notable distinction from the 1⁄8 LD50 and 1⁄4 LD50 treatments, particularly in hooked and notched nuclei abnormalities. Mortality rates were higher in infected groups, peaking at different times with the highest in 1⁄2 LD50. For evaluating Nile tilapia immunity post A. hydrophila infection, it is recommended 1⁄4 LD50 dose and blood collection at 7 and 10 dpi for immunological parameters and abnormalities in Nile tilapia erythrocytes, respectively. | |
