Within an eleven month period (September 1984 to July 1985) fourteen Streptococcus pneumoniae were isolated from varied genital samples (vaginal secretions, IUD, placentas, sperms). The possible carriage and the pathogenicity of pneumococcus are examined. The outbreak of several pooled cases last year, pose a difficult problem.
After determining the LSI80 (light scattering index 80) concentration X and Y of two antibiotics for a given bacteria by an automated light scatter photometric method, we use the same process to test the bacteriostatic effect of all the combinations between the values 2X, X, X/2, X/4, X/8 and 2Y, Y, Y/2, Y/4, Y/8. The results read on the light scatter(More)
Because corynebacteria and mycobacteria have walls of similar composition, it was of interest to test the effects on resistant corynebacteria of two agents with anti-wall effects, i.e., ethambutol (EMB) and isoniazid (INH). Rifampicin was also studied to extend previous data and clarify conflicting results in the literature. INH was not active in levels(More)
From 1973 to 1980 the authors recorded the rates of detection of Mycobacterium tuberculosis in their laboratory. From 1973 to 1978 this rate in samples from children was low, never reaching 6 %, and nearly constant. In the last two years (1979 and 1980) the rate more than doubled. These results are analyzed and discussed according to the age and nationality(More)
