| Atypical changes in hematology and biochemistry of European bison and domestic ruminants with chronic fasciolosis |
| In the recent period, the number of cases of chronic form of liver fluke (Fasciola hepatica) in domestic ruminants has increased. The fluke is the most frequently recorded parasitic disease in bison. The diagnosis of the infection is based on hematological and biochemical blood tests, as well as on serological and coprological examinations. The aim of the study was to compare hematological and biochemical changes that occur in bison living in their natural environment, as well as in dairy cattle and sheep diagnosed with a chronic form of liver fluke. Material and methods: The research included 10 bison, 10 dairy cows and 10 sheep, in which a chronic form of liver fluke was diagnosed by blood tests as well as by coprological and anatomopathological examinations. Blood samples were collected after slaughter (bison) or before treatment (domestic ruminants). A hematological analyzer Horiba was used to determine the following blood parameters: WBC, RBC, PCV, Hb, MCV, MCH, MCHC, platelets, neutrophils, lymphocytes, eosinophils, basophils, and monocytes. A biochemical analyzer Mindray BS-130 was used to determine the concentrations of urea, total cholesterol (Chol), total protein (TP), albumin (ALB), creatinine (CREA), total calcium (tCa), magnesium (Mg), phosphorus (Pn), and ferrum (Fe), as well as the activities of AST, GGTP, and CPK. The concentration of globulins was calculated as the difference between the concentrations of TP and ALB. Results: In bison with a chronic form of liver fluke, hematological examination showed no evidence of changes. In cattle and sheep, the tests revealed normocytic anemia. Some cases of eosinophilia were found among bison and domestic ruminants. In all animals, AST and GGTP were increased. In domestic ruminants, the examination showed a reduction in creatinine and total protein, whereas in sheep, CPK and urea concentration were increased, and albumin was decreased. The content of iron in the blood of domestic ruminants was reduced or normal. |
