. Microbiological factors
In the urine culture results, among the 61 patients with CAUTI, Escherichia coli was the most common bacterium grown; it was identified in 24 patients (38.7%), followed by Enterococcus spp. in 19 patients (30.6%), Staphylococcus aureus in 7 patients (12.9%), Candida spp. in 6 patients (9.7%), Pseudomonas aeruginosa in 3 patients (4.8%), and Klebsiella pneumoniae in 2 patients (3.2%) (Table 3). All patients had growth of a single strain. Six patients had evidence of the growth of extended-spectrum beta lactamase-producing E. coli and two patients had extended-spectrum beta lactamase-producing Klebsiella. Antibiotic sensitivities of the bacteria are shown in Table 4.
