[Evaluation of the lysozyme and DNAase activity for the identification of pathogenic staphylococci]. 1975

L Cava, and R Pozzoli, and F Chiodo

The sensitivity of two tests recently proposed for the classification of pathogen staphylococci were evaluated: --production of DNA-ase with the modified method of Lachica et al.; --production of lisozyme. The two above tests were studied with other six tests on 1,000 strains of staphylococci showing a very high specificity. The Authors propose that the DNA-ase production and the lisozyme production, also for their very simple execution, should become routine tests to identify the strains of pathogenic staphylococci.

D009113 Muramidase A basic enzyme that is present in saliva, tears, egg white, and many animal fluids. It functions as an antibacterial agent. The enzyme catalyzes the hydrolysis of 1,4-beta-linkages between N-acetylmuramic acid and N-acetyl-D-glucosamine residues in peptidoglycan and between N-acetyl-D-glucosamine residues in chitodextrin. EC 3.2.1.17. Lysozyme,Leftose,N-Acetylmuramide Glycanhydrolase,Glycanhydrolase, N-Acetylmuramide,N Acetylmuramide Glycanhydrolase

D013210 Staphylococcus A genus of gram-positive, facultatively anaerobic, coccoid bacteria. Its organisms occur singly, in pairs, and in tetrads and characteristically divide in more than one plane to form irregular clusters. Natural populations of Staphylococcus are found on the skin and mucous membranes of warm-blooded animals. Some species are opportunistic pathogens of humans and animals.
