Effects of C. urealyticum infections and AHA treatments on LNCaP (lymph node carcinoma of the prostate) cell viability. Histograms show mitochondrial respiration rate of LNCaP cells grown in absence (uninfected LNCaP cells) or presence of C. urealyticum strains (ATCC 43042; ATCC 43043; ATCC 43044), without (white histograms) or with two different concentrations (0.25 µg/mL light grey histograms with dots and 0.50 µg/mL black histograms) of AHA for 24h. Results are expressed as percentage. The bars represent means ± SD of three independent experiments performed in triplicate (SD = standard deviation). Statistically significant differences, determined by two-way analysis of variance ANOVA, are indicated: * p < 0.05 versus untreated; § p < 0.05 versus uninfected.
