[Therapeutic impact of streptococcal and enterococcal bacteremia in hematology patients].

From January 1999 to May 2000 (17 months), 21 strains of streptococci and four strains of enterococci have been isolated from 74 blood cultures in 25 infectious episodes in hematologic patients. They concerned 21 patients, of 21 to 77 years old. These patients suffered from acute leukaemia (14 cases), chronic lymphoid leukaemia (two cases), non-Hodgkin's lymphoma (two cases) or myeloma (three cases).

New latex reagent using monoclonal antibodies to capsular polysaccharide for reliable identification of both oxacillin-susceptible and oxacillin-resistant Staphylococcus aureus.

A new latex agglutination test (Pastorex Staph-Plus, Sanofi Diagnostics Pasteur), consisting of a mixture of latex particles coated with fibrinogen and immunoglobulin G for the detection of clumping factor and protein A and latex particles sensitized with monoclonal antibodies directed to Staphylococcus aureus serotype 5 and 8 capsular polysaccharides, was compared with three commercially available rapid agglutination methods for the identification of 220 isolates of S. aureus (61 oxacillin resistant) and 128 isolates of coagulase-negative staphylococci. The sensitivity for identification of S.

Detection of bacteremia in leukemic patients by early subcultures with a slide blood culture system.

During a three month study, 433 sets of blood culture were collected from 140 patients hospitalized in the hematology unit, most of these blood cultures were collected from leukemic patients being treated by chemotherapy producing aplasia. Blood was distributed into three bottles, one containing Schaedler Broth and the others tryptic soy broth (TS). We tried to compare two different blind subculture systems: conventional subculture (CS) onto Petri dishes chocolate agar and a coated agar slide (slide) attached onto the TS bottle, thus the blood culture broth can be subcultured by tipping the bottle.

[Erythrocyte phenotypes in Gabon. I. Hemotypologic data].

Blood group antigens were investigated among 400 gabonese individuals subdivided in 6 ethnic groups. The frequencies were calculated and compared to those reported by MOURANT and al. on geographically close African populations.
