a
A total of 22 and 6 patients receiving and not receiving antibiotics, respectively. Data are expressed as mean log10 CFU ml−1 ± standard deviations (number of patients).
b
ND not detected.
c
Significant difference between the antibiotic-treated and non-antibiotic-treated groups (P < 0.05). Aspirates were obtained from antibiotic-treated and untreated patients, respectively.
d
All genera.
