White piedra and Trichosporon species in equatorial Africa. III. Identification of Trichosporon species by slide agglutination test.

Fifty-two Trichosporon strains isolated from Gabonese female patients 15-60 years, were studied. The identity of these strains was established by two different methods: the method proposed by Guého et al. (1992), based on mycological criteria, and a slide agglutination method performed with monospecific antisera prepared in our laboratory.

White piedra and Trichosporon species in equatorial Africa. II. Clinical and mycological associations: an analysis of 449 superficial inguinal specimens.

Eighty-one of 449 Gabonese female patients examined were found to be positive for genitopubic white piedra. The association with trichobacteriosis is frequent (53 cases), and mostly seen with inguinal intertrigo. Fifty-two strains belonging to the genus Trichosporon were isolated from genital hairs as well as from inguinal intertrigo lesions.

[Cutaneous Alternaria infection occurring in the course of a treated pemphigus].

Alternaria is a very common fungus. Its pathogenic role in human pathology is mainly expressed by asthma. Cutaneous infection is rare and only about 70 cases have been described.

[Treatment of bilharziasis due to Schistosoma mekongi with praziquantel].

After a review of the mechanisms of anti-schistosomal activity of praziquantel and the treatment of Schistosoma mekongi with this drug, the authors report two cases of Schistosoma mekongi treated with praziquantel with failure. Rectal mucosa biopsies are performed and eggs are present. Light microscopic, electron microscopic and on ultra-thin sections examination of these samples don't reveal morphological alterations of Schistosoma mekongi eggs after treatment.

[Schistosoma mekongi bilharziasis along the Mekong River and its affluents, the Mun and Tonle Sap Rivers. General review].

First cases of Schistosomiasis in the South East Asian were described 30 years ago but the existence of a particular species in this area: Schistosoma mekongi has been discussed for a long time. During the last few years, emigration of Laotian and Cambodian people allowed a better knowledge of this affection. Through recent literature the authors make a restatement of the epidemiology, biology and treatment of this disease.
