Plain-English summary
This study looked at a type of skin infection called Tinea corporis, which is caused by a fungus named Microsporum canis. This fungus is common in pets, especially cats and dogs, and can be passed to humans. The researchers found that a cat in a family was the source of the infection, and they used genetic testing to confirm that the same strain of the fungus was involved in both the pet and the family members. This shows how infections can spread from pets to people. The findings highlight the importance of monitoring and managing skin infections in pets to prevent transmission to humans.
Abstract
Microsporum canis, one of the most widespread dermatophytes worldwide, is a zoonotic microorganism that transmits infection from reservoirs such as cats and dogs to humans. This microorganism is associated with Tinea corporis and other clinical manifestations; however, few studies have used genetic surveillance to determine and characterize the process of zoonotic transmission. In this study, we show a clear example of zoonotic transmission from a cat to an intrafamilial environment, where it caused Tinea corporis by infection with M. canis. Molecular characterization using the b-tubulin gene and Random Amplified Polymorphic DNA analysis made it possible to determine that the six isolates of M. canis obtained in this study belonged to the same genetic variant or clone responsible for reservoir-reservoir or reservoir-human transmission.
