Staphylococcus aureus genome screening.

Number of patients carrying the different staphylococcal exotoxins and their agr-related grouping; the p-values for each se were calculated using the Fisher Exact Test; the p-value for the comparison of the total number of se between the groups was calculated using the Mann Whitney U Test. (CRSwNP = Chronic Rhinosinusitis with Nasal Polyposis group; CRSsNP = Chronic Rhinosinusitis without Nasal Polyposis group; NP1-2-3 = Nasal Polyposis grade 1-2-3; Ctl = control group; agr = accessory gene regulator (genotyping marker); se = staphylococcal enterotoxin gene; etA and etB = exfoliatins A and B genes; tsst-1 = Toxic Shock Staphylococcal Toxin-1 gene; pvl = Panton-Valentine leukocidin gene).
