Cell division in Micrococcus pyogenes var. aureus.

Properties of the penicillin binding component of Micrococcus pyogenes.

The antibiotic effect of penicillin on bacterial cells is known to involve the inhibition of a process necessary for cell division but not primarily connected with respiration (Florey et al., 1949). Previous work in which the primary bacteriostatic action of penicillin has been apparently identified with a disturbance in amino acid (Gale, 1952) or nucleotide metabolism (Gros and Macheboeuf, 195...

Fastness of Micrococcus pyogenes var. aureus to subtilin and to combinations of subtilin and streptomycin.

Canbomycin requiring mutants of Micrococcus pyogenes var. aureus.

A single carbomycin' requiring colony was noted (Hsie and Kotz, 1955) while working on the development of resistance to carbomycin in a hemolytic, coagulase positive strain of Micrococcus pyogenes var. aureus. The colony was derived from a "second-step" carbomycin resistant mutant and required a minimum concentration of 1,000 ,ug carbomycin/ml nutrient agar to maintain its maximum growth. When ...

Biosynthesis of Hematin Compounds in a Hemin Requiring Strain of <em>Micrococcus pyogenes</em> var. <em>aureus:</em> I. The Significance of Coenzyme A for the Terminal Synthesis of Catalase

A quantitative study of the phosphatase activity of Micrococcus pyogenes.

The ability of Micrococcus pyogenes var. aureus to produce certain toxins and enzymes has been correlated with the causation of disease in animals and human beings. Various laboratory procedures have been devised to determine the activity of these substances as an index of potential pathogenicity. It is known that nonpathogenic strains may exhibit such activity but to a lesser degree. Therefore...
