From: High level of persister frequency in clinical staphylococcal isolates
Evaluation of persister frequency on different parameters. a Comparison of percentage of persister forming isolates in biofilm producing and non-producing isolates. Persister cells were formed by 51% of TCP positive isolates, while 60% of persister forming isolates was icaAD positive, which is statistically different than that of icaAD negative isolates. b Persister frequency dependency on antibiotic stress used. c Persister frequency on device (catheter, CVC, stent) associated isolates and other specimens (blood, urine, wound/pus). d Staphylococcal species (S. aureus vs CNS). The Chi-square test was used to evaluate the statistical significance of differences in the results. The p value of < 0.05 was considered statistically significant
