[Comparative study of transformation and fusion induced by polyethylene glycol in Acholeplasma laidlawii B]. / Etude comparative de la transformation et de la fusion induite par les polyéthyléleneglycols chez Acholeplasma laidlawii B.

This study showed in Acholeplasma laidlawii the possibility of transformation and fusion of protoplasts after induction by polyethylene glycol. Recombination in a genome of the resistance to chloramphenicol and neomycin has been obtained. Minimal inhibitory concentration of these antibiotics towards the recombined strain are identical to those measured with the parental strains. The most suitable experimental conditions have been studied. It appeared that the fusion, which is cared out more easily than the transformation led to a higher frequency of recombination.

[Comparative study of the in vitro- and vivo- antimicrobial activity of seven antiseptic solutions for use on surgeon's hands (author's transl)]. / Etude comparative de l'activité antimicrobienne in vitro et in vivo de sept solutions destinées à l'antisepsie des mains des chirurgiens.

The antibacterial activity of 7 antiseptic solutions has been studied both "in vitro en in vivo". The results obtained in both case were necessary and complementary since some products (e. g. Solubacter) show an irregular activity either "in vitro or in vivo" but show specific actions which can explain those result. Others (e. g. Betadine scrub), very active in vitro react slowly in vivo. The 3 solutions that have been shown to be the most antibacterial in both cases are 90 degrees alcohol. Remanol and Hibiscrub. Their efficacy has been shown to be fast, regular and relatively long lasting.
