Fig. 1From: Antimicrobial effect of methylene blue in microbiologic culture to diagnose periprosthetic joint infection: an in vitro studyThe mean density of bacteria incubated on agar plates was quantified after 24 h (and standard deviation). *P < 0.05 for the differences among MB 0.1%, MB 0.05% and sterile saline 0.45% groups as shown by the t test or the one-way ANOVA. MB= methylene blue, CFU = colony-forming unit, SAU = Staphylococcus aureus, SEP = Staphylococcus epidermidis, SHO = Staphylococcus hominis, ECO = Escherichia coli, KPN = Klebsiella pneumoniae, ABA = Acinetobacter baumannii, SPY = Streptococcus pyogenes, CAL = Candida albicansBack to article page
