Bovine serum promotes the formation and phenotype memory retention of persister cells in Escherichia coli liquid cultures.

Abstract excerpt

Persister cells, or persisters, are a fraction of bacterial cells that have become temporarily tolerant to antibiotics despite their lack of typical antibiotic-resistant genes. In a previous study, we found that colony-biofilm culture (i.e., biofilm formed at an air-solid interface) promoted the formation and phenotype memory retention of persisters of Escherichia coli and other bacteria. To assess whether these...
