Small-colony variants of Staphylococcus aureus.
Staphylococcus aureus remains a versatile and dangerous pathogen. Small-colony variants (SCVs) of S. aureus are a naturally occurring sub-population, first described nearly 100 years ago. These variants, of which there are different classes, grow slowly and have many atypical characteristics thought to be due to defective electron transport, and include minute colony forms. SCVs have been isola...
متن کاملFrequencies of resistance to Melaleuca alternifolia (tea tree) oil and rifampicin in Staphylococcus aureus, Staphylococcus epidermidis and Enterococcus faecalis.
This study was conducted to determine the frequencies at which single-step mutants resistant to tea tree oil and rifampicin occurred amongst the Gram-positive organisms Staphylococcus aureus, Staphylococcus epidermidis and Enterococcus faecalis. For tea tree oil, resistance frequencies were very low at <10(-9). Single-step mutants resistant to tea tree oil were undetectable at two times the min...
متن کاملTea tree oil as an alternative topical decolonization agent for methicillin-resistant Staphylococcus aureus.
The combination of a 4% tea tree oil nasal ointment and 5% tea tree oil body wash was compared with a standard 2% mupirocin nasal ointment and triclosan body wash for the eradication of methicillin-resistant Staphylococcus aureus carriage. The tea tree oil combination appeared to perform better than the standard combination, although the difference was not statistically significant due to the s...
متن کاملPhenotype microarray profiling of Staphylococcus aureus menD and hemB mutants with the small-colony-variant phenotype.
Standard biochemical tests have revealed that hemin and menadione auxotrophic Staphylococcus aureus small-colony variants (SCVs) exhibit multiple phenotypic changes. To provide a more complete analysis of the SCV phenotype, two genetically defined mutants with a stable SCV phenotype were comprehensively tested. These mutants, generated via mutations in menD or hemB that yielded menadione and he...
متن کاملThymidine auxotrophic Staphylococcus aureus small-colony variant endocarditis and left ventricular assist device infection.
We describe a thymidine-dependent small-colony variant of Staphylococcus aureus associated with left ventricular assist device infection and prosthetic valve and pacemaker endocarditis.
