Small colony variantsとは
Webb16 juni 2016 · Small colony variants (SCVs) can be defined as a naturally occurring sub-population of bacteria characterized by their reduced colony size and distinct biochemical properties. SCVs of Staphylococcus aureus have been studied extensively over the past two decades due to their role in recurrent human infections. WebbThe colonies were re-isolated and characterized as small colony variants (SCVs). A minority of the re-isolated T-1 strain population were able to form colonies of irregular …
