Summary
Common animal fungal infections like Microsporum canis and Trichophyton species are shifting in Japan. Changes in companion animals are increasing the risk of human fungal infections from unusual pathogens.
Area of Science:
- Mycology
- Veterinary Dermatology
- Epidemiology
Context:
- Microsporum canis, Trichophyton verrucosum, and T. mentagrophytes are prevalent dermatophytes in humans and animals.
- Human M. canis infections correlate with companion animals (cats, dogs), showing a decreasing trend in Japan.
- T. verrucosum, typically from cows, has spread beyond farming areas in Japan.
Purpose:
- To analyze the epidemiological trends of common dermatophyte infections in Japan.
- To investigate the emergence of Arthroderma benhamiae (teleomorph of T. mentagrophytes) linked to companion animals.
- To highlight the increasing risk of human fungal infections due to evolving companion animal populations.
Summary:
- Human M. canis infections are declining in Japan, while T. verrucosum shows wider distribution.
- Arthroderma benhamiae, a T. mentagrophytes teleomorph, has spread widely via companion animals since 1980.
- Shifting companion animal trends are increasing human exposure to novel fungal pathogens.
Impact:
- Animal dermatophytoses represent a growing concern for both veterinary and human medical professionals.
- Understanding these epidemiological shifts is crucial for public health and veterinary diagnostics.
- This research underscores the One Health approach in managing zoonotic fungal diseases.
