Control of equine piroplasmosis in Brazil.

The research concentrates on controlling equine piroplasmosis in Brazil, specifically focusing on the effects of tick control and the prevalence of the disease in different climatic conditions. It shows that applying measures to control tick population significantly reduces the prevalence of this horse disease.

Objective of the Study

• The study seeks to monitor the occurrence of equine piroplasmosis, an endemic disease in Brazil, across varying climatic conditions.
• Another objective is to evaluate the effectiveness of a tick control strategy in reducing the infection rates of this disease.

Methodology Deployed

• Researchers collected blood samples from 720 horses on 28 farms situated in various regions of the country.
• These samples underwent complement fixation testing to identify the disease and the severity of it.
• The study utilized tick control as its primary strategy, which entailed spraying horses with acaricides (a pest control substance that kills ticks and mites), treating the horses that tested positive, and avoiding having cattle and horses graze together.

Key Findings

• There is a significant link between the prevalence of antibody titres in equine piroplasmosis and the climate, particularly in tropical and subtropical areas.
• Implementation of measures to control the tick population resulted in a significantly lower prevalence rate of the disease.
• Farms in countries where the disease is endemic, like Brazil, can drastically reduce the prevalence of equine piroplasmosis by controlling the tick population and treating horses that serve as chronic carriers.
• Additional methods for controlling ticks, particularly in tropical climates, were also examined.

Impact of the Study

• The study contributes valuable data for the equine industry, especially in tropical regions where the disease is endemic.
• It demonstrates that effective tick control is integral to successfully managing and reducing the prevalence of equine piroplasmosis.
• The findings emphasize the need for implementing and enforcing disease-control measures on horse farms, which will help maintain the health of the horses and ensure the continued operation of the industry.
