Haematology, plasma biochemistry and serum of table size African catfish, Clarias gariepinus , naturally infected with Listeria species in Oyo State

This study evaluated the haematology, plasma biochemistry and blood enzymes of farm-raised African catfish,Clarias gariepinus, naturally infected with listeriosis in Oyo State. Fish were collected from 36 farms using stratified method. A total of 108 fish were collected where 37 were positive for listeriosis. The blood of the affected fish was used for this study. Haematology, plasma biochemistry and blood enzyme analysis were determined. Fish from Oyo zone had the highest PCV, Hb, RBC and MCHC with 29.33  ± 2.96%, 10.04 ± 1.04 dL, 3.55 ± 0.09 × 106/ μL and 34.24 ± 0.74%, respectively; the highest heterocytes (39.00 ± 5.33%), eosinophils (4.00 ± 1.10%), basophils (0.50 ± 0.55%) and hetero:lymphocyte ratio (0.71 ± 0.14) were recorded in fish from Ogbomosho zone; WBC, platelets, lymphocytes and monocytes were highest in f ish from Saki zone with 18.72 ± 0.44 × 106/ μL, 224.00 ± 3.61 × 103/ μL, 71.33 ± 1.53% and 3.33 ± 0.58%, respectively, while fish from Ibadan/Ibarapa zone had the highest MCV (163.40 ± 44.23 fL) and MCH (52.77 ± 14.95 pg). Total protein and globulin were highest in fish from Oyo zone with 6.61 ± 0.37 and 1.70 ± 0.38 g/dL, respectivel y, while albumin and A:G ratio were highest in fish from Ogbomosho zone. Fish from Ogbomosho zone had the highest AST, ALP, creatinine and glucose with 194.17 ± 10.11 μL, 232.17 ± 63.64 μL, 0.72 ± 0.19 μL and ...
