During the period from December 2003 to August 2004 skin scraping, hairs and nails were collected from 320 patients clinically diagnoses infected with cutaneous mycoses in dermatology department of general Baquba hospital. These specimens were examined by direct a mount with KOH 10% and culture on Sabouraud's Dextrose Agar for isolation and identification of causative fungi.The results showed that 248 were positive for fungi and according to the causative agent, these cases were divided in to 3 groups: Dermatophytoses were common 52.4% followed by Pityriases versicolor 25.8% and those with cutaneous candidiasis21,8%.Clinically dermatophytoses were classified in to six shaped, Tinea corporis was the common 44.6% followed by Tinea capitis 39.2%, Tinea facia 10.8%, Tinea pedis 2.3%, Tinea cruris 1.5% and Tinea palmaris 1.5%, therefor the laboratory cultured examined of specimens that collected from these cases were positive in 107 (82.35%) specimens. Trichophyton mentagrophytes (33.6%)were the predominant type of fungi followed by T.rubrum (21.5), T.verrucosum (16.8%), T.tonsurans (11.2%), T.soudanense (9.3%) and T.violaceum (7.5%), and for the best of our knowledge, the species T.soudanense was isolated for the first time in Iraq.In this study, higher infection rate with T.mentagrophtes (22.4%) and T.verrucosum (11.2%) were found among patients who breed domestic animals inside their houses, However, higer infection rate with T.rubrum (14.9%), T.tonsurans (9.3%), T.soudanese (7.5%), T.violaceum (7.5%) were found among patient who gave positive past family history of dermatophytoses.
