Sero epidemiological study on bovine babesiosis in cattle and buffaloes in Sharkia Governorate, Egypt.

BACKGROUND

Bovine babesiosis represents a serious challenge for animal health, herd production, and profitability. Understanding the epidemiology and risk factors associated with babesiosis is critical to reduce their negative impacts.

AIM

Investigation of the seroprevalence and risk factors associated with () and () in five districts in Sharkia governorate using ELISA.

METHODS

Across-sectional research was conducted to determine the seropositivity of babesiosis by collecting a total of 352 blood samples from 250 cattle and 102 buffaloes. A multivariate logistic regression model was implemented to evaluate the strength of the risk factors associated with both Babesia species infection.

RESULTS

The seroprevalence of and was 42.6% and 17.0 %, respectively. The prevalence of babesiosis in cattle was found to be 48.8% for and 16.8% for . Inclusive, in buffaloes, the prevalence was 27.5% for and 17.6% for . Adult animals were more vulnerable to infection with babesia than young animals by 3-5 times, respectively. Males were more susceptible to and than females by 3.7 and 3.5 times. Similarly, the odds of infection in infested animals with ticks were 2-4 times higher than in animals without ticks.

CONCLUSION

The obtained results revealed that age, sex of the animal, and tick infestation were major risk factors for the seropositivity of both Babesia species. Inclusive, there was no evidence to support the premise that seroprevalence of babesiosis is correlated with the season and species.
