[Effectivity of murein preparations in the phage inhibition test--effect of Ca++ions and EDTA].

The inactivating efficacy for the typing phages 54, 83A, and 187 of the peptidoglycan of Staphylococcus aureus is decreased by increasing the Ca++-content of the medium; the irreversible inhibition of phage 187 becomes reversible. The percentage of its inhibition is proportional to the Ca++-content of the medium. Minute amounts of phage 187 bound irreversibly under Ca++-deprivation can be loosened by addition of Ca++-ions. Addition of EDTA up to the equivalence concentration of Ca++ present in the medium has no influence. Addition of EDTA up to the tenfold equivalence causes a significant increase of the inactivating efficacy of the peptidoglycan.

[Effect of peptidoglycan preparations on phage inactivation: decrease in phage 187 binding using monosaccharides].

Monosaccharides were found to be capable to decreasing the binding of phage 187 with peptidoglycan. Galactosamine hydrochloride and glucosamine hydrochloride proved to be the most effective, followed in order of decreasing activity by N-acetylgalactosamine, N-acetylglucosamine, glucose and galactose; mannose produced a weak effect. Ca2+ ions increased the reduction of phage peptiglycan binding with N-acetylgalactosamine and N-acetylglucosamine. Both of these monosaccharides also reduced the adsorption of phage 187 by the Staphylococcus aureus cells. In the medium enriched with Ca2+ ions; in the absence of Ca2+, they were, however, incapable of releasing the phage irreversibly bound with the peptidoglycan.
