Webb11 apr. 2024 · Phenotype switching has been linked to persistence in host cells, treatment failure and the development of chronic and recurrent infections. Staphylococcal small colony variants (SCVs) and persister cells (PCs) are among the cell types raising the greatest scientific interest. WebbStaphylococcus aureus can mutate to form a sub-population of bacteria known as small colony variants (SCVs). These bacteria have a characteristic phenotype defined by slow growth, the lack of pigment, an altered pattern of carbohydrate utilization, and a reduction in toxin production.
