abstract
The present study was carried out in a 5 year old, female, Holstein Friesian cow that was presented with fever, paleness of mucous membranes, dyspnoea and coffee colored urine. Peripheral blood samples from ear vein and whole blood samples from jugular vein were collected for thin blood smear examination and haematology. Ticks present on the animal were collected for identification of vector. Results revealed piroplasms of Babesia in erythrocytes by giemsa staining of thin blood smear. Haematology showed significant decrease in Haemoglobin (Hb), Packed Cell Volume (PCV) and Total Erythrocyte Count (TEC). The ticks were identified as Riphicephalus spp.
