Abstract
The present research was undertaken to study the prevalence, clinico pathology,
diagnosis and therapeutic evaluation of Bovine theileriosis in and around Hassan District.
Bovine theileriosis is highly prevalent in Hassan District with 17.69 per cent in
prospective study. In the present study Bovine theileriosis is more prevalent in female
animal compared to male animals and is more prevalent in crossbred animals than Non-
Descript cattle. The disease was more prevalent in cattle aged in the range of 2-6 years
followed by age group more than 6 years and cattle less than 2 years. The disease was
more prevalent in post monsoon followed by summer, monsoon and least in winter
season. Cattle in post parturient period suffered more followed by animals which were
pregnant compared to lactating non pregnant animals. Major clinical signs seen in
Bovine theileriosis are anorexia, decreased production, pale CMM, enlarged LN, tick
infestation with increased temperature, HR and RR. Hematological studies revealed
decreased Hb, TEC, PCV suggestive of anaemia and analysis of erythrocytic indices
indicated macrocytic normocytic anemia. Biochemical studies revealed decreased blood
glucose, total protein, albumin, globulin, cholesterol level and increase in BUN, ALT,
AST, total bilirubin, direct and indirect bilirubin. Molecular diagnosis was found to be
highly specific and sensitive diagnostic test and can be considered as gold standard test
to detect Bovine theileriosis. Sensitivity and specificity of blood smear was found to be
84 and 100 per cent respectively. T. orientalis infection was more in and around Hassan
District followed by mixed infection with both T. orientalis and T. annulata and T.
annulata infection alone. Therapeutic studies revealed that Buparvoquone was found to
be more effective drug compared with Imidocarb dipropionate in the treatment of
Bovine theileriosis. Herbal extract of C. procera was found to be more effective, better
than Imidocarb dipropionate in the treatment of Bovine theileriosis, however was found
to be comparatively less effective than Buparvoquone in the treatment of Bovine
theileriosis. Considering high cost of Buparvoquone for treating Bovine theileriosis,
herbal extract of C. procera may be used as an alternative therapy or for best result it
can be combined with Buparvoquone as a complementary therapy
