Comparison of Dermatophytes and Other Agents of Human Dermatitis between Males and Females in Jos, Plateau State, Nigeria

Abstract

Dermatophytes are a group of three genera of fungi namely Microsporum spp, Trichophyton spp and Epidermophyton spp that commonly cause infections of the skin, hair and nails due to their ability to utilize keratin in both man and animals. Dermatophytes and other agents of human dermatitis are believed to have gender predisposition because of the anatomical and physiological nature of these genders. A study was undertaken to compare the distribution of dermatophytes and other agents of human dermatitis in patients who visited the Dermatophilosis Research Laboratory, National Veterinary Research Institute, Vom, Plateau State of Nigeria. A total of 1551 patients were involved in this study from 2003 to 2007; 823 of whom were males and 728 females. Samples collected were skin scrapping, nails, hair and pus exudates. They were processed according to standard procedures. Nine hundred and thirty two (60%) were positive for dermatophytes and other agents. Sporothrix schenckii (138 (12.4%)), Aspergillus flavus (128 (11.5%)), and Trichophyton mentagrophytes (112 (10.1%)), Mucor sp (105 (9.5%)) were the most commonly isolated fungi. Aspergillus flavus occurred more in males (74 (6.7%)) while Sporothrix schenckii was more in females (71 (6.4%)). More isolation was made from the head in males (185 (19.8%)) while in females more isolation was made from their limbs (150 (16.1%)). Males generally were more affected with skin infections than females.
