Dermatophytosis Frequently called ringworm, is a fungal infection affecting the skin and nails. About 95% of feline cases are caused by Microsporum canis. The cat is also infected by Trichophyton species. Direct exposure to a fungus does not necessarily result in an infection, and an infection does not always cause clinical signs. Long-haired cats are more likely to have symptomatic infections. The typical incubation period is 1-4 weeks, but some cats remain asymptomatic carriers for long periods of time. Lesions may have the typical appearance of circular areas of hair loss, but their appearance can be diverse. Diagnosis is carried out by a Wood's lamp examination which is an ultraviolet light that causes some strains of ringworm to fluoresce. Positive confirmation is by fungal culture from areas affected by the disorder. this may take 7-14 days to perform. Treatment can be carried out with both topical shampoos or oral medication. It is extremely important to isolate any affected animals and clean and disinfect the environment as thoroughly as possible. The prognosis is generally good if aggressive therapeutic measures are taken. This infection can spread easily to other animals and people. The organism can remain in the environment for up to one year. |
