Lytic Susceptibility of Staphylococcal L-Forms to Lysolecithin

Lytic activity of the recombinant staphylococcal bacteriophage Φ

Induction and cultivation of staphylococcal L forms in the presence of methicillin.

Susceptibility to polymyxin B in penicillin G-induced Proteus mirabilis L forms and spheroplasts.

A polymyxin B-resistant strain of Proteus mirabilis was converted into L forms and spheroplasts in the presence of penicillin G. This treatment caused a 400-fold increase in polymyxin B susceptibility. The acquired susceptibility was in the range of the natural susceptibility reported for susceptible gram-negative bacteria ( approximately 1 mug/ml). The high susceptibility to polymyxin B was lo...

Applications of quadratic D-forms to generalized quadratic forms

In this paper, we study generalized quadratic forms over a division algebra with involution of the first kind in characteristic two. For this, we associate to every generalized quadratic from a quadratic form on its underlying vector space. It is shown that this form determines the isotropy behavior and the isometry class of generalized quadratic forms.

Correlation of staphylococcal bacteriophage types to L-form colony production.

The ability of 258 strains of Staphylococcus aureus and 132 strains of S. epidermidis to produce L-form colonies in a standard environment was investigated. Production of these colonies by S. aureus was correlated with their phage type. Phage type 7 strains produced L-form colonies in larger numbers and more consistently than those of phage type 80/81. No L-form colonies were produced by the S....
