[13 Years of veterinary mycological routine diagnostics. Isolation of dermatophytes in the years 1965-1977].

The research details a 13-year study of veterinary mycological diagnostics, examining the types of dermatophytes, a form of fungus, found in different animal species. Despite an increase in diagnostic samples, the proportion and types of dermatophytes found remained consistent throughout the study period.

Study Overview

• The researchers conducted a long-term study over a period of 13 years, from 1965 to 1977, analyzing a total of 4790 skin scrapings and hair samples from various animals.
• A total of 887 strains of dermatophytes, a type of fungal infection, were isolated from 885 samples, representing 18.5% of the total samples examined.

Main Findings

• The most common type of dermatophyte identified was Trichophyton verrucosum, mostly found in cattle. This was followed by Microsporum canis, which was isolated from cats, dogs, and zoo animals.
• Another strain, Trichophyton mentagrophytes, was predominantly found on guinea pigs, chinchillas, and dogs, whereas Trichophyton equinum was primarily found on horses.

Trends and Consistency

• The study highlights that despite an increase in the number of samples examined in the last eight years of the study, the total number of dermatophytes isolated remained proportionally the same.
• There was no significant change in the relative numbers of the various species of dermatophytes isolated within the period of investigation.

Implications of the Study

• This study provides valuable information for veterinary diagnostic procedures and treatments, as it offers insights into the prevalence and types of dermatophytes commonly found in different animals.
• The consistent proportion and types of dermatophytes found over the long study period also indicate the persistent nature of these fungal infections, suggesting the need for ongoing monitoring and effective treatment strategies in veterinary medicine.
