The prevalence of haemoprotozoan disease in crossbred cattle was studied by screening 132 clinically suspected blood samples by Geimsa's stained blood smear method. Among 132 crossbred cattle screened, 57 animals were found positive for haemoprotozoan parasites. Out of 57 positive cases, 41 were found positive for Theileria annulata and the remaining 16 were positive for Babesia bibemina. The highest prevalence was found in 4-6 year age group and in monsoon months. The hematological observation revealed reduced Hb, TEC and PCV in the infected animals. The treatment with buparvaquone and oxytetracyclin for theileriosis and diminazine aceturate for babesiosis are found effective.

A study was conducted to record the prevalence of Haemoprotozoan infections in bovines of Shimoga region for a period of 1 year from April 2012 to March 2013. A total of 300 blood samples were examined for the presence of haemoprotozoan parasites, of which 215 from cattle and 85 from buffaloes were examined by Giemsa staining technique. Out of 300 blood samples examined, 130 (43.3 %) were found positive for Haemoprotozoan infections. Out of 215 cattle blood samples examined, 62 (28.8 %) were positive for Theileria annulata, 27 (12.5 %) were harbored Babesia bigemina, 15 (6.9 %) were found positive for Trypanosoma evansi and 06 (2.7 %) samples showed Anaplasma marginale. Among 85 buffalo samples examined, 11 (12.9 %) were showed Theileria spp, 04 (4.7 %) found positive for B. bigemina, 03 (3.5 %) were found positive for T. evansi and 02 (2.3 %) were positive for A. marginale. Among haemoprotozoan parasites, the highest prevalence was observed with T. annulata followed by B. bigemina and T. evansi infection. The lowest prevalence was observed with A. marginale infection.

The study was conducted to ascertain the actual status of gastro-intestinal parasites in pigs maintained under different rearing systems in Shimoga region, Karnataka state. A total of 150 Pigs fecal samples were examined, which includes 50 from organized piggery farm, Veterinary College Shimoga, 50 from private piggery farm of Shimoga and 50 from free range desi pigs of Shimoga city. The fecal samples were processed and examined by direct and sedimentation method. Out of 50 fecal samples examined from organized piggery farm, 19 were found positive for different parasitic eggs, Out of 50 fecal samples screened form private farm, 28 harbored different parasites, whereas from 50 free range desi pigs fecal samples examined, all showed one and other parasitic eggs/ova. The percent prevalence of parasitic infection is more in free range desi pigs compared to Yorkshire breeds maintained under stall fed condition.

A study was conducted to ascertain the incidence of gastrointestinal parasites in horses of Shimoga region, to generate the data regarding status of parasitic infections of equines in Karnataka state due to paucity of information. A total of 100 fresh fecal samples of equines were collected and examined by direct and sedimentation method for the detection of parasitic egg/ova. Among 100 samples examined, 84 (84.0 %) were found positive for various gastrointestinal helminths. Out of 84 positive cases, 44 (52.38 %) were found positive for Strongylus spp. eggs, 09 (10.71 %) showed Parascaris equorum eggs, 06 (7.14 %) had Gastrodiscus spp. eggs, 04 (4.76 %) harbored Oxyuris equi and the remaining 21 (25.0 %) had a mixed infection of Strongylus spp., Strongyloides spp. and Gastrodiscus spp.
