The Presence of Peptidoglycan O -Acetyltransferase in Various Staphylococcal Species Correlates with Lysozyme Resistance and Pathogenicity

22 Jul 2006

Abstract excerpt

Human-pathogenic bacteria that are able to cause persistent infections must have developed mechanisms to resist the immune defense system. Lysozyme, a cell wall-lytic enzyme, is one of the first defense compounds induced in serum and tissues after the onset of infection. Recently, we showed that Staphylococcus aureus is resistant to lysozyme by O acetylating its peptidoglycan (PG) by O-acetyltransferase (OatA)....
