Zoonotic
The most commonly acquired zoonotic disease among British veterinarians is:
Ringworm
Classification of Dermatophytes:
Found mainly in animals but can be transmitted to animals
Zoophilic
Classification of Dermatophytes:
Found mainly in man and rarely transmitted to animals
Anthropophilic
Classification of Dermatophytes:
Found mainly in soil and can infect man and animals
(the primary source of transmission)
Geophilic
What are the modes of transmission of Ringworm?
- Aerosol of hair, skin dander, clippers
- Spread by direct contact with the infected host having the infective element
(different types of spores can be formed)
Fungus remains viable for __________ to ____________ in shed epithelial cells
months, years
What is the incubation period for Tinea in Human Infections?
1-2 weeks
What are the two dermatophytes that you would be most likely to communicate to your clients about their zoonotic potential?
Microsporum spp. and Trichophyton spp.
