[Apalcillin: in vitro activity compared with that of carbenicillin, ticarcillin, mezlocillin, piperacillin against Enterobacteriaceae and Acinetobacter].

The in vitro activity of apalcillin was compared with that of carbenicillin, ticarcillin, mezlocillin and piperacillin against clinical isolates of Enterobacteriaceae and Acinetobacter. 1 168 strains were tested by a routine disk diffusion method. They were grouped into different patterns of resistance by results to ampicillin, carbenicillin and cephalotin.

[Haemophilus infections in pediatrics. Characterization of strains by biotype, serotype and the production of beta-lastamase].

During 1980 and 1981, an epidemiological survey (biotyping, serotyping, beta-lactamase production) of Haemophilus strains isolated in our hospital was performed. One hundred sixty-one Haemophilus were isolated among 146 patients: 17 H. parainfluenzae and 144 H.
