Bacteriolytic activity in staphylococci.
The bacteriolytic activity of Staphylococcus aureus and Staphylococcus albus strains was tested with various media. Whereas S. aureus strains were found to be active under all conditions, the percentage of active S. albus strains was significantly influenced by the composition of the medium. Ionic strength and concentration of the organic nitrogen source were found to be the main factors affect...
متن کاملRoutine separation of staphylococci from micrococci based on bacteriolytic activity production.
A new method is described by which separation of staphylococci from micrococci can be achieved in routine laboratory use. The basis of this method is that bacteriolytic activity is produced by staphylococci but not by micrococci.
متن کاملPseudocoagulase activity of staphylococci.
A total of 245 strains of staphylococci isolated from various pathological specimens derived from cases of human infections was tested for staphylocoagulase activity. Test systems employing normal citrated rabbit plasma and the same substrate supplemented with inhibitors of thrombin and proteolytic enzymes (but not influencing the staphylocoagulase activity) were used for testing suspensions of...
متن کاملThe Complement-dependent Bacteriolytic Activity of Normal Human Serum
The bacteriolytic activity of normal human serum on a rough strain of E. coli has been studied by a turbidimetric method. Bacteriolysis was found to be markedly dependent on ionic strength and pH, with optima at micro = 0.06 and pH 8.3-8.5, respectively. The method of cultivating the cells also influenced the rapidity of lysis. Lysis was temperature-dependent and was exhibited by all samples of...
متن کاملGrowth and bacteriolytic activity of a soil amoeba, Hartmannella glebae.
A soil amoeba, Hartmannella glebae, could grow on a variety of gram-positive and gram-negative bacteria, although the rate of growth was faster in the presence of gram-negative bacteria. The amoeba, however, could not use yeasts, molds, or a green alga as a nutritional source. The extract prepared from amoebae grown in the presence of Aerobacter aerogenes and Alcaligenes faecalis could lyse int...
