Abstract
Aim:
The ringworms of pet dogs, cats, and stray animals (dogs,
cats, and other animals) could be a potential source of zoonotic
infections causing a serious public health problem in the busy
city Kolkata. The pet owners are more susceptible to get this
infection from their pets, because of the close contact with them
as dermatophytosis is very much prevalent in those pets. So, this
study was aimed to check the prevalence of dermatophytosis in
dogs, cats, and in pet owners.
Materials and Methods: A total of 362 clinically suspected
cases of dermatophytosis from dogs (123 in number), cats (202 in
number), and human beings (37 in number) were collected and
studied from in and around Kolkata to detect the presence of
significant dermatophytes. Direct microscopy and cultural
examination of the isolates were performed following standard
methodology. Identification and characterization of the isolates
were done by different biochemical tests.
Results: Samples (n=285) having significant dermatophytic
fungal infections were found to be of highest number in cats (158,
55.5%) than in dogs (108, 37.8%) and humans (19, 6.7%),
respectively. The incidence of Microsporum canis (60.0%)
was the highest from affecting dogs, cats, and human beings in
comparison to Microsporum gypseum (22.5%), Trichophyton
mentagrophytes (15.8%) and Trichophyton rubrum (1.7%).
Detection of T. rubrum was only from human cases in this
study, whereas the presence of rest three were slightly higher in
cats than that of the dogs and humans in this present study. The
incidences were higher in young animals and in humans of the age
group of 21-30 years, during the rainy season (from April to
August) and also in in-contact human beings.
Conclusion: M. canis was the most commonly pathogen
among all causing dermatophytosis in animals and also in the pet
owners. M. gypseum and T. mentagrophytes were other
pathogens associated with these infections. These infections were
more prevalent in the rainy seasons and in in-contact human
patients or pet owners.
Keywords: cats, dermatophytes, dogs, humans,
zoonotic infections.
