Effect of carbonyl cyanide m-chlorophenylhydrazone on Escherichia coli halotolerance.

The growth-inhibitory effect of carbonyl cyanide m-chlorophenylhydrazone (CCCP) was less on members of the family Enterobacteriaceae (halotolerant organisms) than it was on species of Vibrio (moderately halophilic organisms). When sodium chloride concentration increased from 0.5 to 0.85 M, this effect was more pronounced for Escherichia coli; it remained relatively stable for Vibrio spp. The effect of carbonyl cyanide m-chlorophenylhydrazone was antagonized by the addition of glycine betaine or proline or by growth in a rich medium.

Two plasmid-determined restriction and modification systems in Streptococcus lactis.

Two restriction and modification systems were found in Streptococcus lactis strain IL594 which was found to contain 9 plasmids designated pIL1 to pIL9. On the basis of protoplast-induced curing experiments, we showed that a restriction and modification system was related to the presence of pIL6 or pIL7. The pIL6-determined restriction and modification system was confirmed by cotransfer of the plasmid and of the restriction and modification system to a plasmid-free, nonrestricting, and nonmodifying derivative of S. lactis IL594.

[Bacteriostatic activity of apalcillin on Gram-negative bacilli and strict anaerobic bacteria. Multicenter study].

This work reports a multicenter study of the bacteriostatic activity of apalcillin, a new N-acyl-penicillin, against 1 827 clinical isolates of Gram-negative bacilli and obligate anaerobes. The modal minimal inhibitory concentrations (MICs) for susceptible strains are (mg/l) : Salmonella-Shigella : 1 ; E. coli : 0.5-2 ; Klebsiella : 4 ; Citrobacter : 1-2 ; Enterobacter : 2 ; Serratia : 8 ; Proteus-Providencia : 1 ; Acinetobacter : 1-4 ; P. aeruginosa : 2 ; H. influenzae : 0.06 ; C. perfringens : 0.03-01 ; Peptococcus : 0.2 ; B. fragilis : 16. Against Enterobacteriaceae and Acinetobacter, apalcillin is as active as mezlocillin and piperacillin, and much more than carbenicillin. Against P. aeruginosa, apalcillin is the most active penicillin : 2 to 16 fold more active than azlocillin and piperacillin, and 2 to 128 fold more active than ticarcillin. Against H. influenzae, C. perfringens and Peptococcus, apalcillin has MICs similar to those of other N-acyl penicillins, and inferior to those of carboxypenicillins . Apalcillin, as other penicillins, is poorly active against B. fragilis.

[Sensitivity of Pseudomonas aeruginosa to beta-lactam antibiotics and effects of beta-lactamases].

The activities of carbenicillin, ticarcillin, piperacillin, cefsulodin, ceftriaxone, azlocillin, ceftazidime and apalcillin were evaluated against 128 hospital isolates of Pseudomonas aeruginosa. Against the 85 isolates that were susceptible to carbenicillin, apalcillin had the best minimal inhibitory concentrations, the median MIC being 1, 1 microgram/ml. Against the 43 isolates resistant to carbenicillin, ceftazidime inhibited 90% of organisms at a concentration of 16 micrograms/ml. A constitutive beta-lactamase, was found in 27 of the 43 resistant isolates. All the 128 isolates, but one, were producers of an inducers of an inducible beta-lactamase. Ceftriaxone, piperacillin and azlocillin were highly antagonized by cefoxitin. The extent of antagonism was lower with ticarcillin and carbenicillin.
