摘要
The aim of the study was to determine the prevalence of Haemoprotozoan species of bovines and canines in Chittoor District of Andhra Pradesh State. A total of 1,035 blood samples were examined for the presence of different haemoprotozoan parasites by Giemsa staining. Out of 1,035 blood samples, 190 (18.36%) samples were positive on blood smear examination by Giemsa staining technique. Out of 769 samples screened in bovine, 109 (14.2%) were found positive on blood smear examination for various blood protozoans. In Bovines, PCR was performed to detect only Theileria and Babesia. Out of 210 blood samples, 111 (52.86%) were found positive by PCR in bovines. Further, on blood smear examination in bovines out of 109 positives, Theleria-56 (51.38%) followed by Babesia-42 (38.53%), Tryps-6 (5.50%), Anaplasma-4 (3.67%) and Microfilaria-1 (0.92%) were reported. But on PCR, Theleria-64 (57.66) \u0026 Babesia-47 (42.34%) were reported. In canines, out of 266 samples screened in canines, 81 samples (30.45%) showed positive on blood smear examination with Geimsa staining technique. On PCR, out of 337 samples screened in canines, 89 (26.41%) samples were positive to various blood haemoprotozoans. Out of 81 positives on blood smear examination includes Babesia canis-38 (46.91%) followed by Babesia gibsoni-24(29.63%), E.canis-11(13.58%) and H.canis-8 (9.88%). Similarly, out of 89 positives on PCR revealed Babesia canis-49 (55.05%) followed by Babesia gibsoni-26 (29.21%), Ehrlichia.canis-14 (15.73%) respectively.
