Chlorhexidine did not inhibit ATPase in intact cells of Escherichia coli K12 W1317i-, even at bactericidal concentrations, and ATP hydrolysis was greatest at the highest concentration (40 mg/l), even though no net uptake of substrate occurred. Like d

A correlation between the multiple drug resistance patterns and the plasmid profiles given by 70 clinical isolates of Shigella sonnei and Shigella flexneri was investigated in this study. The most common plasmids were purified from different isolates

Chlorhexidine and sulphadiazine react synergistically against strains of Pseudomonas. Proteus and Staphylococcus, with high factors of synergy. The impermeability of these strains to sulphadiazine is destroyed by low concentrations of chlorhexidine,

Direct microscopical observations of single developing cysts in sealed slide microcultures prepared from 5-days-old tube cultures of the Reiter treponeme revealed two distinct phases in the life cycle. In one phase transverse fission was the main met

Spores of Bacillus subtilis MD2 and var. niger were dry-heat damaged at 150°, 160° and 170°C and recovered on media of increasing complexity. The greater the heat dose the more marked was the effect of amino acid supplements on recovery. For strai

Chlorhexidine acts synergistically with the polymyxins B and E causing increased and rapid release of cell contents from Pseudomonas aeruginosa. While the polymyxin target molecule is phospholipid, evidence is provided for the proposal that the prima

The effect of visible radiations on the germination and outgrowth of spores of Bacillus subtilis MD2 and Bacillus subtilis var. niger was determined by direct observation of populations irradiated on the surface of nutrient agar. Little effect on ger

SUMMARY The efficiency of an automatic dry heat instrument sterilizer was tested using as test inoculum a mixture of spores of Bacillus subtilis strain MD2 and B. subtilis var. niger as air dried films on stainless steel and glass objects. The steril

Summary: The generation times of individual Escherichia coli cells inoculated on to a cellophane membrane surrounded by liquid synthetic medium in a continuous flow system were determined by direct observation for up to seven generations. The presenc
