Epidemiology and control of parasites in northern temperate regions.

The research focuses on the rise in drug resistance among equine parasites, making traditional methods less effective. The article looks into alternative solutions for equine parasite control, including prophylactic treatments and a non-chemical approach involving regular pasture cleaning.

Epidemiological Concerns and Drug Resistance

• The research starts by acknowledging the growing issue of drug resistance among parasites affecting horses in Northern temperate regions. This development raises serious concerns about the effectiveness of current methodologies that are largely dependent on chemical control measures.
• The report emphasizes the need for new strategies in parasite control due to the worrying prevalence of drug-resistant parasites. This resistance poses a potential risk to horse populations and can have significant impacts on equine health and wellbeing.

Alternate Prophylactic Approach

• The researchers, identifying the limitations of current practices, suggest a strategic switch to a prophylactic or preventive approach. These treatments are proposed for the spring and summer seasons when horses are most vulnerable to parasitic infections.
• This alternative approach targets strongyles and colic, common equine diseases. It is believed to exert less pressure for drug resistance among the parasites due to the preliminary nature of the intervention, decreasing the likelihood of the development of resistance over time.

Non-Chemical Strategy

• In addition to the prophylactic treatments, a non-chemical strategy involving regular pasture cleaning is also suggested. This technique aims at directly reducing the number of parasites in the horses’ environment, therefore decreasing the chances of infection.
• Pasture cleaning is recommended to be done twice a week, a frequency believed to maximally disrupt the lifecycle and spread of the parasites.
• As an added advantage, this practice can also lead to a significant increase in grazing areas for horses, by about 50 per cent. It not only offers a solution for the control of drug-resistent parasites but also enhances the utilization of pasture land within horse farms.
