Table 2 Mean and standard deviation of the different parameters (thickness, death, covered surface, autofluorescence) of each strain under different conditions of inoculation (24, 48, and 72 hours of exposure to the ciprofloxacin), and control without antibiotic (96 hours)

From: Effect of ciprofloxacin in the ultrastructure and development of biofilms formed by rapidly growing mycobacteria
