“…Because dogs are commonly sniffing and potentially tracking close to the ground, it is logical that the majority of lesions appear on the muzzle and head. It previously has been reported that the face is most commonly affected initially and then progresses to the head and ears 3,6 . Interestingly, some studies have noted a high incidence of feet being affected, this was not found in our study.…”

“…However, the T. mentagrophytes complex has been noted to be the most prevalent cause of dermatophytosis in India, 4 and the second most common cause of dermatophytosis in Croatia, UK, Iran and Puerto Rico 5–8 . In the southern United States, Brazil and Italy, the T. mentagrophytes complex is the third most reported cause of dermatophytosis 1,3,9–11 . While some of these prevalence studies were performed more recently worldwide, most of the studies originating in the United States are 30–70 years old, indicating a need for updated information.…”

“…The most prevalent causative fungal species for dermatophytosis is variable depending on the region or country. Frequent causative agents include Microsporum canis , M. gypseum and the Trichophyton mentagrophytes complex 3 . In most countries, M. canis has been the most reported causative agent.…”

Background There are limited clinical studies evaluating the Trichophyton mentagrophytes complex, with most reports confined to small case studies. Additionally, the studies are dated and provide limited information on response to newer or currently available therapies. Hypothesis/Objectives The aim of the study was to determine if there is a breed prevalence, lesion distribution and seasonality associated with the T. mentagrophytes complex for dogs evaluated in the central United States. An additional aim of the study was to evaluate response to therapies because there are minimal data available on clinical response with newer systemic antifungal drugs. Animals A total of 64 canine medical records were evaluated that had a previous diagnosis of T. mentagrophytes complex infection. Materials and Methods A retrospective study of medical records to evaluate signalment, time of onset of clinical signs, clinical presentation and therapeutic management. Results A higher incidence of T. mentagrophytes complex infection was observed in the American Kennel Club (AKC) Sporting group (43%) and Terrier group (20%). A seasonal influence was noted, with the onset of clinical signs being highest in October. Lesions most often affected the muzzle (48%), followed by the head excluding the pinnae (21%). Ketoconazole, itraconazole and terbinafine appeared equivalent as systemic therapeutic options to treat T. mentagrophytes complex infections. Conclusions and Clinical Relevance This study identified patterns in breeds, seasonality and lesion distribution for the T. mentagrophytes complex in dogs from the central United States. Additionally, the study found several reasonable and reliable treatment options for systemic therapy.
