ABSTRACT

Background: Microsporum(M.) canis is a zoophilic dermatophyte commonly acquired from cats ordogs, and it is the most common pathogen of tinea capitis in Korea. An increase in the incidence of M. canis infection has been observed after 1970s. Objective: To investigate the changes in epidemiological features and clinical findings on M. canisinfection. Methods: We retrospectively carried out an analysis of 133 patients with M. canis infection amongclinically suspected dermatophytosis during last 10 years, from 2001 to 2010. Results: The isolation rate of M. canis was 5.9% of all isolated dermatophytes. The annual numberof patients infected by M. canis has fluctuated between 8 and 22 and was highest in 2007. The infectionswere most prevalent in patients under the age of 10 years (51.1%). The ratio of male to female patientswas 0.8:1 in total, but 1.1:1 in children under the age of 10 years, and 0.4:1 in adults. Seasonally, 58.6%(78 cases) occurred in winter and spring, which was more prevalent than in other seasons. The highestclinical type among dermatophytosis was tinea capitis (56.4%), and followed by tinea faciale (15.8%),and tinea corporis (15.0%). The incidence of patients with the noninflammatory lesions (68.3%) intinea capitis was higher than inflammatory lesions (31.7%) in clinical characteristics. Conclusion: We analyzed the patients with dermatophytosis caused by M. canis during last 10 years,from 2001 to 2010, and their prevalence, seasonal changes, and clinical charateristics were demonstratedand compared with previous studies.
