Hemo-parasitic Infections in Cattle: Insights from India

Prevalence, Co-infection Patterns, and Risk Factors of Anaplasma, Babesia, Theileria, and Trypanosoma in Cattle and Buffaloes across Different Farming Systems in India

Hemo-parasitic infections pose major challenges to bovine health in India. Researchers conduct cross-sectional studies to assess these threats. They screen apparently healthy cattle and buffaloes from various farms. PCR assays detect carrier status effectively. Scientists target specific genes for accurate identification of each parasite.

Overall infection rates reach notable levels. About 30 percent of screened animals carry at least one hemo-parasite. Cattle show higher positivity than buffaloes. Indigenous breeds display greater susceptibility compared to cross-breeds and exotic animals. Farm-level prevalence varies widely. Some units record very low rates while others approach complete infection.

Anaplasma marginale emerges as the most common pathogen. Theileria annulata follows closely. Babesia species and Trypanosoma appear less frequently. Co-infections occur in a substantial share of positive cases. Most dual infections involve Anaplasma marginale together with Theileria annulata. Other combinations remain rare.

Farming systems influence risk. Organized farms and unorganized setups both face exposure. Tick presence and management practices drive transmission. Enzootic instability appears in multiple farms. This pattern signals potential for future outbreaks.

Whole-herd screening becomes essential. Prompt treatment of infected animals helps limit spread. Better farm management practices reduce production losses. Continuous surveillance supports early detection. These steps protect dairy productivity across different systems in India.
