title: [Place of Staphylococcus aureus in the bacterial isolations of the University Hospital Center of Dakar. Preliminary results of serotyping and phage typing].
abstract: Out of 18 837 strains isolated between 1972 and 1980, by the laboratory of bacteriology of the Dakar Teaching Hospital, 2 925 strains of Staphylococcus aureus have been identified. This germ was the cause of 14,4 p. 100 of all diagnosed septicemia, ranging second in frequency after Salmonella. It was the most frequent germ in pura (54,8 p. 100 of strains) and rated 29,2 p. 100 of the strains isolated from pleural fluids. It was less frequent in bacterial meningitidis (2,5 p. 100) and in infections of the urinary tract (3,6 p. 100). About one hundred coagulase + strains were studied further. A clumping factor was found in 98 p. 100 of the strains (Staphyslide test). In addition, serotyping and lysotyping were carried out: --80,8 p. 100 of strains were lysotyped --25,6 p. 100 of them belonging to type I --7,7 p. 100 to type II --10,3 p. 100 to type III --33,3 p. 100 belonging to two or three types --11,5 p. 100 to I and II --16,7 p. 100 to I and III --5,1 p. 100 to I and II and III Some strains gave positive responses with 94-96 and 187 phages.
