Researchers in Brazil discovered the first case of a serious fungal infection called sporotrichosis in a domestic cat in the Goiania metropolitan area. The infection was caused by a fungus called Sporothrix brasiliensis, which can spread from cats to humans through scratches and bites. This finding is important because it shows the disease is spreading to new regions of Brazil that previously didn’t have confirmed cases, and suggests residents need to be cautious around stray cats.
