Distribution and Characteristics of Bacteria Isolated from Cystic Fibrosis Patients with Pulmonary Exacerbation

Figure 2

Population structure of S. aureus isolates. (a) Relative frequency of resistance to antibiotics in S. aureus isolates and biofilm formation status. (b) Relative frequency of MDR and non-MDRS. aureus isolates vs. age group. (c) Overview of antimicrobial-resistance profiles and other characteristics of S. aureus isolates. ATH, azithromycin; ER, erythromycin; FOX, cefoxitin; RIF, rifampin; GM, gentamicin; CIP, ciprofloxacin; SXT, trimethoprim-sulfamethoxazole; CLI, clindamycin; TET, tetracycline; age group is represented as A < 2, B 2–5, C 6–10, D 11–15, E 16–20, F 20–30 years of age; spa types are shown in front of isolate code; S, S. aureus; a and b letters represent the different morphotypes of the same bacteria isolated from the same patient; red squares are representative of resistance and white squares represent susceptibility to the tested antibiotic.
