Dermatophytosis is an infectious and zoonotic disease caused by species belonging to the genera Microsporum, Trichophyton, and Epidermophyton that affects the hair follicles, nails, and keratin layer of the epidermis. The aim of this study was to determine the prevalence of dermatophytosis in different animal species with clinical lesions. To this end, a total of 395 skin scraping and hair materials taken from cat, dog, horse, parrot, and calf with dermatophytosis suspicion that presented to the Department of Microbiology of the Ankara University Faculty of Veterinary Medicine between 2014 and 2017 in different seasons were investigated. A mycological analysis of the materials was conducted involving direct microscopy and a fungal culture test. Of the 395 materials tested, 117 (29.62%) were positive for dermatophytosis with the following distribution: Microsporum spp., 34 of 195 cats, 24 of 181 dogs, two of 11 horses; Trichophyton spp., 26 of 181 dogs, 25 of 195 cats, one of 11 horses, one of three calves, and two of five parrots; Epidermophyton spp. two of 195 cats. The dermatophyte isolation rate was relatively higher in the summer (36.06%) and spring (29.51%) for cats, and in fall (30%) and spring (26%) for dogs.

Bu çalışmada, deri enfeksiyonu olan 77 köpekten 61 Staphylococcus pseudintermedius suşu izole edilmiştir. Yaygın olarak kullanılan antibiyotiklere karşı antimikrobiyal direnç, disk difüzyon yöntemi ile değerlendirildi. Penisilin ve metisilin direncinden sorumlu sırasıyla blaZ ve mecA genlerinin varlığı PCR ile araştırıldı. S. pseudintermedius izolatları tetrasiklin (% 47.5) ve penisiline (% 40.9) yüksek direnç gösterirken, tüm izolatlar amikasine (% 100) duyarlıydı. 18 metisiline dirençli S. pseudintermedius (MRSP) suşunun tümü mecA geni için pozitif iken blaZ genine sahip 25 S. pseudintermedius suşu izolatı da fenotipik olarak penisiline dirençliydi. 18 MRSP izolatından 14 S. pseudintermedius suşu, üç veya daha fazla antibiyotiğe dirençliydi, bu da bu suşların çoklu ilaç direnci (MDR) gösterdiğini ortaya koydu. Bu rapor, S. pseudintermedius'un köpek deri enfeksiyonlarından en sık izole edilen bakteri olduğuna dair önceki bulguları doğrulamaktadır. Bu çalışmada test edilen tüm S. pseudintermedius suşları amikasine duyarlı olduğundan, amikasinin S. pseudintermedius enfeksiyonlarının tedavisinde yararlı bir ajan olduğu sonucuna varılabilir., In this study, 61 Staphylococcus pseudintermedius strains were isolated from 77 dogs with skin infections. Antimicrobial resistance to commonly used antibiotics was evaluated by disc diffusion method. The presence of the blaZ and mecA genes responsible respectively for penicillin and methicillin resistance were investigated by PCR. The S. pseudintermedius isolates were highly resistant to tetracycline (47.5%) and penicillin (40.9%) while all isolates were susceptible to amikacin (100%). All 18 methicillin-resistant S. pseudintermedius (MRSP) strains were positive for the mecA gene while the 25 S. pseudintermedius strain isolates with the blaZ gene were also resistant to penicillin phenotypically. Of the 18 MRSP isolates, 14 S. pseudintermedius strains were resistant to three or more antibiotics, indicating that these strains showed multiple drug resistance (MDR). This report confirms previous findings that S. pseudintermedius is the most frequently isolated bacteria from dog skin infections. It can also be concluded that amikacin is a useful agent for treating S. pseudintermedius infections since all the S. pseudintermedius strains tested in this study were susceptible to amikacin.
