title: [Haemophilus influenzae: sensitivity to 12 antibiotics, analysis according to capsular serotype, biotype and source of isolation, and epidemiologic implications].
abstract: A total of 129 strains of Haemophilus influenzae were tested for susceptibility to twelve antibiotics. Capsular serotypes and biotypes were determined, and the relation between these parameters and minimal inhibitory concentrations (MIC) were analysed. Non-capsulated strains were more susceptible to streptomycin than capsulated ones. The distribution of MIC of chloramphenicol among biotypes was different. The distribution of MIC of penicillin G, tetracycline and chloramphenicol among sources of isolation was also different. Therefore the strains did not have the same origin, and one should look at the concept of organotropism for H. influenzae.
