Molecular survey in relation to risk factors and haemato-biochemical alteration in Theileria equi infection of equines in Punjab Province, India.

The research article presents a study on the infection by Theileria equi in equines (horses, donkeys, and mules) in Punjab, India, their possible risk factors, and how it affected the animals’ blood and biochemical makeup.

Research Objective and Methodology

• The study aimed at understanding the prevalence and effects of Theileria equi, a parasite causing equine piroplasmosis, on the equine population in different regions of Punjab province in India.
• The article offers an investigative report on 464 equids (426 horses and 38 donkeys/mules) and is based on both traditional methods (blood smear examination) and modern techniques like PCR (Polymerase Chain Reaction).
• The focus was on finding the connection between the prevalence of this infection and the physical factors like temperature and aridity of the region. The impact of the disease on the physical well-being (haemato-biochemical values) of the animals was also analysed.

Findings and Conclusion

• The findings showed that there was a direct relationship between the climate of the region and the incidence of the infection. Regions with higher temperatures and more arid conditions had higher infection rates.
• A spatial distribution analysis showed that the disease prevalence increased from the north-eastern region to the south-western region of Punjab.
• The scientists also observed a decrease in the total red blood cell count and haemoglobin levels in infected equids. There was also an increase in mean corpuscular haemoglobin, serum globulin, glucose, creatinine, aspartate aminotransferase, and bilirubin levels.
• The study thus highlighted the endemic presence of equine theileriosis in Punjab. It also brought to light the potential risk factors and the possible effects of the infection on the infected animals.

Significance of the Study

• This is reportedly the first comprehensive epidemiological survey report of T. equi infection in Punjab province.
• The study underscored the significance of certain physical factors like temperature and aridity in the spread of the infection.
• The haemato-biochemical alterations in the infected animals provide insights into the effects of the infection and can help in early detection and treatment strategies.
• The use of PCR has particularly been instrumental in tracing the latent infection of T. equi and can aid in future research and control plans.
