Webb1 maj 2010 · The role of Staphylococcus aureus small-colony variants (SCVs) in the pathogenesis of biofilm-associated infections remains unclear. This study investigated the mechanism behind increased biofilm-forming potential of a menadione-auxotrophic Staphylococcus aureus SCV compared with the wild-type parental strain, as recently … Webb1 jan. 2024 · Purpose. Thymidine-dependent small-colony variants (TD-SCVs) are difficult to detect or test for antimicrobial susceptibility. We investigated the characteristics of clonal TD-SCVs of Escherichia coli, both with and without bla CTX-M-3, isolated from a patient. Methodology. Mutation in the thyA gene was analysed by sequencing, and … how to make scrambled eggs video
