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.

摘要

目的

监狱内真菌感染的防治工作是普通人群中这些疾病防治总体框架的一部分。为助力这些疾病的防治工作，我们在瓦加杜古大监狱的囚犯中开展了本研究。其目的是分析瓦加杜古监狱囚犯浅表真菌感染的流行病学和病因学方面。

材料与方法

这是一项分析性描述性研究（2011年12月至2012年4月），对采用分层抽样选取的212名被拘留者进行了检查。首先是对危险因素进行调查。其次，从患有浅表真菌病可疑病变的囚犯身上取样。对于每个病变，取一些碎片直接在载玻片和盖玻片之间用10%或30%的氢氧化钾进行检查。其余碎片接种在沙氏氯霉素培养基和沙氏氯霉素放线菌酮培养基上。然后将培养基在27°C下培养1个月，之后再宣布任何阴性结果。

结果

瓦加杜古监狱囚犯中浅表真菌感染的总体患病率为25.5%。近期入狱的囚犯（≤24个月）受影响最大（89.8%）。皮肤癣菌（15.56%）比非皮肤癣菌（12.26%）分离出的更多。嗜人种类在皮肤癣菌中占主导：须癣毛癣菌（7.0%）、红色毛癣菌（3.3%）、兰氏毛癣菌（23%）、絮状表皮癣菌（1.41%）和紫色毛癣菌（0.94%）。石膏样毛癣菌（0.47%）是唯一遇到的土源性种类。非皮肤癣菌为马拉色菌属（11.79%）和念珠菌属（0.47%）。多重寄生情况较少（占感染囚犯的7.4%）。几个身体部位大多由一种真菌病原体感染。花斑癣是最常见的真菌感染（37.31%）。
