[Extrapulmonary tuberculosis in Africans (author's transl)].

Extra pulmonary tuberculosis are frequent in Africa and have a special severity due to delayed diagnosis and multifocal forms. Various punctures and biopsies may be necessary to demonstate the tuberculous infection. Even with modern treatment it too often implies important risks of severe sequelae.

[Staining of Mycobacteria using non-traditional methods].

Nine modifications of the Gram method were tested with respect to their ability to stain mycobacteria. The results obtained were rather variable. Moreover it appeared that not all the methods would reliably visualize mycobacteria within histological sections. In particular, the mycobacteria occurring in a case of fibrocaseous tuberculosis appeared to be less stainable by the Gram method. If the Ziehl-Neelsen and the Gram method were combined to stain a single section, only some mycobacteria appeared to take the blue Gram stain.
