[Description of the first cases of serotype A, sequence type (ST)-11 meningococcal meningitis in Senegal]. / A propos des premiers cas sénegalais de méningite à méningocoques W135 de séquence type (ST)-11.

Senegal is located in the African meningitis belt and meningococcal meniningitis outbreaks are yearly events. Occurrence of an epidemic involving serogroup W135 in 2000 and its spread following the Hajj (pilgrimage to Mecca) exposed the strongly Moslem population of Senegal to the risk of early infection. Indeed the first two cases in Dakar occurred simultaneously with the spread of this epidemic strain. The purpose of this article is to describe clinical, laboratory, and therapeutic findings in these two cases and the results of the ensuing epidemiological survey. The relationship with the pilgrimage and consequences on public health in Senegal are discussed.

[Five cases of chromomycosis in Gabon (author's transl)]. / A propos de cinq cas récents de chromomycose au Gabon.

Five cases of chromomycosis were studied in the parasitological and mycological department of the National Laboratory and C.U.S.S. in Libreville (Gabon). Different types of lesions were observed which were more often maculous than verrucous. In one case, it was localized on the upper limb, and in four cases on the lower limbs. They all were diagnosed after a 2 to 25 years evolution. Fonsecaea pedrosoï was isolated in every case. Direct examinations always recovered the classical scleratic cells : in one case it was budding, and in two cases abundant mycelium was seen. No epidemiological argument can explain the geographical distribution.
