[Epidemiological and etiological aspects of superficial fungal infections among prison inmates in Ouagadougou, Burkina Faso]

Abstract

Objective: The fight against fungal infections in prisons is within the overall framework of the fight against these diseases in the general population. To contribute to the fight against these diseases, we conducted this study among inmates of the big prison of Ouagadougou. It aimed to analyze the epidemiological and etiological aspects of superficial fungal infections among prison inmates in Ouagadougou.

Materials and methods: It was a matter of an analytical descriptive study (December 2011-April 2012) that examined 212 selected using a stratified sampling detainees. It consisted firstly of a survey on risk factors. Secondly, samples were taken from prisoners with suspicious lesions of superficial mycoses. For each lesion, some fragments were examined directly between slide and coverslip in KOH (10% or 30%). The remaining fragments were cultured on Sabouraud-Chloramphenicol and Sabouraud-Chloramphenicol-Actidione. The media were then incubated at 27°C for 1 month before declaring any negativity.

Results: The overall prevalence of superficial fungal infections among prison inmates Ouagadougou was 25.5%. The recent prison inmates (≤24 months) were the most affected (89.8%). Dermatophytes (15.56%) were more isolated than non-dermatophytes (12.26%) Anthropophilic species predominated among dermatophytes: T. mentagrophytes (7.0%), T. rubrum (3.3%), M. langeronii (23%), E. floccosum (1.41%) and T. violaceum (0.94%). M. gypseum (0.47%) was the only land-based species encountered. Non-dermatophytes were Malassezia sp. (11.79%) and Candida sp. (0.47%). Polyparasitism was less represented (7.4% of infected prisoners). Several body sites were mostly infected by one fungal agent. Pityriasis versicolor was the most common fungal infection (37.31%).

Conclusion: Considering the results, specific control measures are to be taken against the superficial fungal infections in prisons and in the general population.
