[Sensitivity of 7 mycobacterial species to new quinolones].

The authors have tested the sensibility to three new quinolones of forty one strains of mycobacteria belonging to seven different species. They have observed, in particular, susceptibility for the species M. tuberculosis, M. fortuitum, M. kansasii, M. marinum and M. xenopi to ciprofloxacin and ofloxacin and a limited sensibility for these same species to pefloxacin. In association with others antibiotics, amikacin, erythromycin, thienamycin, trimethoprim-sulfamethoxazole, the three have shown some additive effects and in a few cases synergistic effects.

[Value of the germ-carrier method for testing of the activity of disinfectants against mycobacteria strains].

We investigated bactericidal activity of four disinfectants against mycobacterium smegmatis and others mycobacteria species such as those responsible for respiratory and lymphadenitis diseases. We used the germ carried method according to all the AFNOR requisites changing only the strains culture conditions and for some studies time of contact (15 and 30 minutes). In addition we realized a preliminary essay to control efficacy of washing in order to maximally eliminate the product after the time of contact. Under AFNOR standard conditions (15 minutes) only phenolic complex and glutaraldehyde solution were bactericidal for all strains including M. tuberculosis. Another series of test with contact during 30 minutes showed that with aldehyde and quaternary ammonium compounds bactericidal activity was limited against M. fortuitum and M. chelonei and nearly non existent at usual concentrations against M. kansasii, M. avium and M. tuberculosis.

[Clinical and pharmacokinetic study of ceftriaxone in severe infections in adults in intensive care].

Twenty patients with severe nosocomial bacterial infections hospitalized in an intensive care unit were treated by ceftriaxone alone, in a single daily IV injection of 2 g. Clinical and bacteriological results show that ceftriaxone has good activity against enterobacteria. The four patients (20%) who failed to respond had superinfection by Pseudomonas aeruginosa, a finding that suggests that ceftriaxone should be used in combination with another antibiotic for the treatment of nosocomial infections. Pharmacokinetic results in our patients show that with the dosage used peak and trough serum levels are greater than the MICs of susceptible pathogens.

[Measure of the activity of a quaternary aldehyde-ammonia complex against reference bacteria strains and 50 hospital strains].

Concentrations of a disinfectant complex effective against hospital strains were determined using the dilution-neutralization method (AFNOR T72 150). Results were compared to those obtained with reference bacterial strains. A 99.999% reduction in viable bacteria requires significantly higher concentrations for hospital isolates than for reference strains.

[Chemoprevention with intravenous doxycycline in 40 cases of colonic esophagoplasty].

Doxycycline was used to prevent infection in 40 patients undergoing oesophageal surgery (for carcinoma in 35 and for benign lesions in 5). Treatment began with induction of anaesthesia and continued in doses of at least 200 mg/day for a mean period of 10 days. Concentrations of the antibiotic were measured in the serum and colonic tissue of 20 patients, 2 hours on average after the first injection. Mean serum and tissue levels were 4.1 +/- 0.8 mcg.ml-1 and 2.9 +/- mcg.ml-1 respectively, with a tissue to serum ratio of 0.7. This ratio remained practically unchanged between the first and fourth hours post-injection. Doxycycline was successful in preventing post-operative infection in 75% of the cases. No infection due to anaerobic organisms was observed.

[Antibacterial kinetics of fosfomycin (author's transl)].

The authors studied, with the Autobac machine, the kinetics of antibacterial activity of fosfomycin against Staphylococcus aureus, Streptococcus D' Streptococcus pneumoniae, Neisseria meningitidis, Acinetobactor lwoffi, Haemophilus influenzae, Salmonella typhimurium, Escherichia coli, Proteus rettgeri, Klebsiella pneumoniae, Serratia marcescens and Pseudomonas aeruginosa. A correlation appears between the kinetics of fosformycin antibacterial action and the microbial growth rate.

[Bactericidal power's assessment of eight antiseptic products intended to surgeon's hand-washing (author's transl)].

A standard hand-washing technique was used in order to test the relative effectiveness of eight both detergent and alcoholic preparations intended to surgeon's hands disinfection. A single four or seven minutes washing with alcoholic solutions was shown to eliminate a much larger proportion of the skin flora than could be removed by a single four or seven minutes hand-washing with detergent antiseptic preparations. Authors have also determined effect of wearing surgical rubber gloves after skin disinfection and compared viable bacterial counts in hand washings immediately after the antiseptic treatment and when gloves had been worn for one hour.
