Summary
A rabbit infected with dermatophytosis transmitted the fungal species Arthroderma benhamiae to its owners. Identification was confirmed through mating tests and chitin synthase 1 gene analysis.
Area of Science:
- Mycology
- Veterinary Dermatology
- Infectious Diseases
Background:
- Dermatophytosis is a common superficial fungal infection affecting various animals and humans.
- Zoonotic transmission of dermatophytes poses a public health concern.
- Arthroderma species are known dermatophytes with potential for interspecies transmission.
Observation:
- A rabbit presented with clinical signs of dermatophytosis.
- The infection was subsequently transmitted from the rabbit to its human owners.
- This suggested a potential zoonotic fungal agent.
Findings:
- The fungal isolate was identified as Arthroderma benhamiae using mating experiments.
- Chitin synthase 1 (CHSI) gene sequencing further confirmed the identification of Arthroderma benhamiae.
- The mating experiments indicated the isolate was of the (-) mating type.
Implications:
- This case highlights Arthroderma benhamiae as a significant zoonotic pathogen.
- Accurate identification of the causative agent is crucial for effective treatment and prevention of spread.
- Understanding mating types can be important for fungal population genetics and epidemiology.
