Horse and donkey parasitology: differences and analogies for a correct diagnostic and management of major helminth infections.

The research discusses the similarities and differences in parasitic infections in horses and donkeys, emphasizing the importance of tailored treatments based on their specific attributes.

Overview of the Research

• The research paper was presented at the XXXII Conference of the Italian Society of Parasitology and revolves around endoparasitic infections of horses and donkeys.
• Despite being genetically different, horses and donkeys can be infected by a similar range of parasites such as small and large strongyles, and other spp.
• The study discusses how horses and donkeys exhibit distinct biodiversity, distribution and intensity of helminth parasites based on location and breed.

Comparisons and Contrasts

• The report suggests that heavily infected donkeys tend to show fewer clinical signs than horses.
• The risk of drug-resistant parasitic infection is conveyed, which can occur passively in donkeys sharing pasture with horses. Parasite control is primarily aimed at horses, indicating a potential oversight in the management of donkey infections.

Recommended Treatments

• The authors recommend using selective treatment for both species based on fecal egg counts due to the possibility of decreased drug efficacy (<90 or 80%).
• They suggest adult horses should receive treatment when the fecal egg count threshold exceeds 200-500 eggs per gram (EPG) of small strongyles.
• The research does not provide precise indications for donkeys, although a fecal egg count value above 300 EPG seems to be a safe recommendation.

The study emphasizes the need to understand the dynamics of helminth infections between the two species better, thereby prompting more effective parasitic infection control and management methods.
