Abstract: A five-months pregnant Jersey cross-bred was presented to the Teaching Veterinary Clinical Complex, Veterinary College and Research Institute, Tirunelveli, with enlarged superficial lymph nodes, reduced feed intake, hind-limb weakness with tremors, and mucus-coated faeces. One week earlier, the cow had been treated by a field veterinarian for recumbency and weakness. Cytological examination of a lymph node aspirate revealed lymphocytes and monocytes containing characteristic Koch’s blue bodies along with eosinophils. A diagnosis of the lymphoproliferative form of bovine tropical theileriosis caused by Theileria annulata was established. The animal was treated with oxytetracycline and supportive therapy, leading to complete recovery. This case highlights the diagnostic value of cytology for rapid identification of T. annulata infection and demonstrates the effectiveness of timely therapy in pregnant Jersey cross-bred cattle.
