- Abstract
The present study evaluated the acute inflammatory response induced by carrageeiun (500 pg) injected in the swim bladder of Nile tilapia, after fed or not probiotic supplemented diet. Fifty four fish were distributed in six treatments and diree replicates: Group A: Fish fed unsupplemented diet: 0.5 mL saline-injected fish; fish injected with 500 pg carragecnin diluted in 0.5 mL saline; Non-injected. Group B: Fish fed probiotic supplemented diet: saline-injected fish; carrageenin-injected fish; Non-injected. Fifteen days after feeding the fish were injected with carrageenin or saline. After six hours, inflammatory exudate was collected, as well as the blood for hematocrit, red blood cell (RBC) and white blood cell (WBC) counts, differential count of leucocytes and phagocytic activity in the blood. Supplementation with probiotic did not influence the RBC, hematocrit and the numbers of lymphocytes and basophils in the blood. The number of neutrophils was significantly higher in supplemented fish injected with carrageeiun. Glucose concentration in supplemented and non-injected fish was higher than that observed in the saline injected ones. Probiotic potcntialized the migration of cells to the inflammatory focus in the animals injected with the carrageenm irritant. In fish injected with saline and carragcenin occurred the greatest phagocytic activity in the bkxxl in relation to those treatments.
