Parasitic fauna of Polish konik horses (Equus caballus gmelini Antonius) and their impact on breeding: a review.

This research reviews the impact of internal and external parasites on Polish konik horses. The findings include data from several authors over the last half-century, and add recent research which reveals 38 types of helminths and five Diptera species in the horses, as well as parasites Cryptosporidium spp., Theileria equi, and Anaplasma phagocytophilum.

Introduction

The research paper focuses on examining the impact of parasites on the health and breeding of Polish konik horses. These horses are managed under different strategies in Poland. The study uses a comprehensive approach, consolidating data from different authors spanning the past 50 years, combined with more recent research findings.

Findings

• The research identifies a total of 38 species of helminths affecting the horses. These parasitic worms include 37 Nematoda and one Cestoda. Helminths can have various detrimental effects on the horses, such as diminished vitality or even death in severe infestations.
• Additionally, five species of Diptera, a large order of insects that includes flies and mosquitoes, were discovered among the hosts. Diptera are vectors for numerous diseases and are capable of causing significant harm.

New Parasites Identified

• The researchers discovered the presence of Cryptosporidium spp. in Polish konik horses. Cryptosporidium is a microscopic parasite that causes the diarrheal disease cryptosporidiosis. Previous knowledge has indicated that these organisms are most commonly found in drinking water and recreational water sources. This is the first time they were identified in these horses in Poland.
• Theileria equi, another parasite, was also detected for the first time. This tick-borne organism causes a form of equine piroplasmosis, a disease that can lead to anemia, fever, weight loss, and sometimes death in horses.
• The study also revealed the presence of Anaplasma phagocytophilum. This particular bacterium, which is transmitted by ticks, causes a disease known as equine granulocytic anaplasmosis.

The researchers found these parasites for the first time in the Polish konik horses, suggesting that these horses are getting exposed to new types of infections which need further exploration and mitigation strategies to secure the health and breeding capacity of these horses.
