Staphylococcus aureus is a common constituent of the bacterial community inhabiting the airways of persons with cystic fibrosis (CF). Culture-independent studies have shown that this species is often present in relatively high abundance and would therefore be expected to exert a pronounced effect on measures of CF airway bacterial community structure. We investigated the impact of DNA extractio...
LAS enzymes are a group of metallopeptidases that share an active site architecture and a core folding motif and have been named according to the group members lysostaphin, D-Ala-D-Ala carboxypeptidase and sonic hedgehog. Escherichia coli MepA is a periplasmic, penicillin-insensitive murein endopeptidase that cleaves the D-alanyl-meso-2,6-diamino-pimelyl amide bond in E. coli peptidoglycan. The...
Staphylococcus aureus remains one of the most common and at the same time the most dangerous bacteria. The spreading antibiotic resistance calls for intensification of research on staphylococcal physiology and development of new strategies for combating this threatening pathogen. We have engineered new chimeric enzymes comprising the enzymatically active domain (EAD) of autolysin LytM from S. a...
The fluorescent dye ethidium bromide stains Escherichia coli and Staphylococcus aureus in whole blood. The staining is rapid, relatively specific, and does not require fixation of the sample. Furthermore, stained bacteria can be seen microscopically without the need for a final wash to remove unbound dye. By using lysostaphin, an S. aureus-specific lytic enzyme, we have demonstrated that S. aur...
