Piroplasmosis in an endemic area: analysis of the risk factors and their implications in the control of Theileriosis and Babesiosis in horses.

Abstract: Theileria equi (Laveran 1901) and Babesia caballi (Nuttall and Strickland 1910) are the causative agents of Equine Piroplasmosis (EP), a severe and problematic disease compromising international movement of horses. Infected horses usually become asymptomatic carriers and, for this reason, their movement across borders may become restricted. The aim of this study was to assess the seroprevalence of EP in Southern France and to evaluate risk factors associated with these parasites. In 2002, we performed a complement fixation test (CF) with blood samples from 443 horses stabled at 95 different farms located in the region of Camargue. Two epidemiological questionnaires have been used: one for each single horse (individual and management factors) and one for each place where horses were sampled (environment, presence of other species, etc.) to identify risk factors for seropositivity. T. equi and B. caballi had a seroprevalence of 58 % and 12.9%, respectively. For T. equi, sex, age, activity, management, and living with or near cattle were identified as risk factors, while for B. caballi, only living in wetlands was recognized as a risk factor in the bivariate analysis. In the multivariate analysis, the best model for T. equi included as variables age, breed, and deworming, while the best model for B. caballi included the type of housing during day and the contact with cows.

This research paper examines the risk factors related to Equine Piroplasmosis, a severe disease affecting horses, focusing on the Southern France and determining the prevalence of this disease in the area. The key risk factors for the disease are identified with the intent of helping to control the spread of the ailment.

Objectives and Methodology

The study was instigated with the primary aim of gauging the prevalence of Equine Piroplasmosis (EP) in Southern France and determining the risk factors related to the disease. The disease is primarily caused by two parasites, Theileria equi and Babesia caballi.

  • In the study, a Complement Fixation test was carried out on blood samples from 443 horses located across 95 different farms in the Camargue region.
  • Two different epidemiological questionnaires were used to gather data; one focused on individual factors and management of each horse, and the other concerned the environment and presence of other species where the horses were located.

Findings

The primary causes of Equine Piroplasmosis, Theileria equi and Babesia caballi, registered a seroprevalence of 58% and 12.9% respectively.

  • For T. equi, the identified risk factors included: horse’s sex, age, activity, management, and proximity to cattle.
  • For B. caballi, living in a wetland was the single recognized risk factor in the bivariate analysis.

Multivariate Analysis

In the Multivariate Analysis section, each parasite has a different set of risk factors:

  • For T. equi, the significant variables identified included horse’s age, breed, and deworming practices.
  • The most effective model for B. caballi risk factors included the type of housing during the day and contact with cows.

Research Implication

This research is crucial for effectively managing and controlling the spread of Equine Piroplasmosis. By identifying the risk factors, strategies can be developed to minimize contact with these risks, reducing the rate of infection and facilitating the international movement of horses.
