|Title:||Hematological alterations caused by high intensity of L-3 larvae of Contracaecum sp Railliet & Henry, 1912 (Nematoda, Anisakidae) in the stomach of Hoplias malabaricus in lakes in Pirassununga, So Paulo|
|Abstract:||The objective of the present study was to discover the hematological indices of Hoplias malabaricus infected by larvae of Contracaecum sp. A total of 105 fish were collected from two lakes located in the municipal district of Pirassununga, So Paulo, Brazil, of which 95.2 % were infested by L-3 larvae of Contracaecum sp., with an average intensity of 348.7 +/- 231.55 helminths/fish. A total of 76 fish were analyzed to establish hematological parameters. Following analysis, it was found that there was a significant difference between hematological parameters Hct, erythrocytes (Er), thrombocytopenia (p = 0.01), and Hb (p = 0.02) in lakes A and B, while there was no significant difference for leukocyte (p = 0.68), mean corpuscular volume, mean corpuscular hemoglobin (p = 0.06), and mean corpuscular hemoglobin concentration (p = 0.47). The intensity of infection correlated negatively with Er (r (s) = -0.42; p < 0.01) and positively for (r (s) = 0.48; p < 0.01). The high intensity of infection by Contracaecum sp. in H. malabaricus did not affect the health of the fish despite causing alterations in hematological variables.|
