Studies on the prevalence of ringworm among horses in racing and breeding stables.

The research focuses on investigating the prevalence of ringworm, a type of fungal infection, among horses in training and breeding stables, with results showing significantly higher infection rates among horses in training.

Objective of the Research

• The primary goal of this study was to assess the extent of ringworm, which are pathogenic dermatophytes, among horses that are either in training or part of breeding farms. Dermatophytes, of which ringworm is one strain, are fungi that can cause infections in the skin.

Sample Population and Results

• The researchers examined two groups, one consisting of 568 horses in training, and the second made up of 2,535 horses on breeding farms.
• Analysis of the data collected showed that 32% of the horses in training had clinical signs of ringworm infection. In contrast, only 1.1% of the horses on breeding farms showed signs of the same infection.
• The differences in the prevalence of the infection indicate that horses in training may be more susceptible to ringworm, perhaps due to the nature of their environment or their activities.

Distribution and Types of Dermatophytes

• Most of the ringworm lesions on the racing horses were found around the girth areas, which are generally covered by the gear used for racing.
• The study distinguished the specific types of dermatophytes prevalent amongst the horses. These included Trichophyton equinum var. autotrophicum, M. canis, and M. equinum. Interestingly, these strains of fungi were exclusively found in racing horses.
• M. gypseum is another type of dermatophyte, found not only in racing horses but also in riding and breeding horses. It indicates the possibility of this strain being more widespread and not specifically associated with horse racing activities.

Conclusion

• This study provides insight into the incidence of ringworm infections in horses involved in different activities, with racing horses being much more prone to the fungal infection.
• The results may aid in the development of appropriate prevention and treatment strategies. The findings could lead to changes in either the care and hygiene practices within training stables or the design and use of racing gear to reduce the incidence of these infections.
