Assays of resistance to HNP-1, HBD-2, lysozyme and lactoferrin employed a drop method to assess bacterial survival #Foretinib supplier randurls[1|1|,|CHEM1|]# and colony morphology could not be accurately
determined. Statistical analysis Statistical analysis was performed using the statistical program STATA version 10.1. Log transformation of continuous dependent variables was performed as appropriate. Nested repeated measures ANOVA was used to test continuous dependent variables between 3 isogenic morphotypes. A difference between 3 morphotypes was considered to be statistically significant when the P value was less than or equal to 0.05, after which pairwise comparisons were performed between each morphotype. All P values for pairwise analyses were corrected using the Benjamini-Hochberg method for multiple comparisons [26]. Acknowledgements We are grateful to Dr. Suwimol Taweechaisupapong and Dr. Jan G.M.
