An Epidemiological Study of Feline and Canine Dermatophytoses in Japan

Abstract

In a 2012-2014 epidemiological study of feline and canine dermatophytoses in Japan, we investigated the prevalence of fungi among 296 cats and 170 dogs treated at a veterinary clinic and 51 cats and dogs at an animal shelter at Fukui City in Japan. Microsporum canis was isolated from only one cat out of the 517 animals. Also, from 2012 to 2017, we analyzed isolates from 76 cats and 15 dogs with dermatophytoses at 14 veterinary clinics across 10 prefectures in Honshu and Shikoku. M. canis was the cause for 85 of the cases and Microsporum gypseum for the other six. M. canis infection routes in cats are thought to include stray cats as well as breeding facilities and pet shops, whereas for dogs, only breeding facilities and pet shops. Tinea was found in 18.7 % (14/75) of the owners of these animals. We showed that microsatellite genotyping is useful for molecular epidemiological investigations such as determination of infection routes of M. canis.

Epidemiologic and Molecular Characterization of Zoonotic Dermatophytes from Pet Dogs and Cats in Egypt

“…A higher isolation rate was detected mainly from outdoor dogs and cats that were reared in pet animal facilities (41.17 and 32.72%) than household ones (9.37 and 8.8%) respectively, as denoted in Table 3. Such obtained data was parallel to that achieved by Copetti et al (2006) and Yamada et al (2019), which implies that outdoor transmission acted as a major infection route for ringworm. This could be referred to the unsanitary conditions as well as the high stocking density in such places, as well as the fungal spores cross contamination between healthy animals and diseased ones with skin mycosis which confirms the natural route of dermatophyte infection especially with M. canis as assumed by Minnat and Khalaf (2019).…”

Human and Zoonotic Dermatophytoses: Epidemiological Aspects

“…In a survey of a few hundred cats and dogs from households, shelters, pet shops, or stray, conducted by Yamada et al (2019) in Japan, M. canis was absent or had a very low prevalence (1.1-3%) in the surveyed areas. The fungus was, however, more prevalent (21.5%) in cats in animal raising establishments.…”

Molecular Epidemiology of <i>Microsporum canis</i> Isolated from Japanese Cats and Dogs, and from Pet Owners by Multilocus Microsatellite Typing Fragment Analysis

“…Our recent epidemiological studies of dermatophytosis of pet animals in Japan (9,10) showed that M. canis was the most prevalent causative fungus in both cats and dogs. In cats, there are two major reservoirs of the fungus: pet shops and commercial breeding facilities (PS), and stray cats and pet cats that go outdoors and come in contact with stray cats (Outdoor).…”

“…In cats, there are two major reservoirs of the fungus: pet shops and commercial breeding facilities (PS), and stray cats and pet cats that go outdoors and come in contact with stray cats (Outdoor). In dogs, there is only one reservoir, the PS route (10). However, the infection status of the fungus among the reservoirs and risk of contagion to humans are still unclear.…”

“…The present study was designed to determine the MLMT genotypes of M. canis strains isolated in recent years from feline and canine dermatophytoses in Japan and to evaluate the roles of these animals as reservoirs of M. canis (10).…”
