Table 3 Susceptibility to selected antibiotics or their combinations of bacterial flora in patients with benign prostatic hyperplasia and indwelling catheters

From: Catheter-associated bacterial flora in patients with benign prostatic hyperplasia: shift in antimicrobial susceptibility pattern

  1994–96 2004–06 2011–15 P value
No. of patients 169 132 156  
No. of patients with bacteriuria 119 (70%) 95 (72%) 107 (69%)  
Bacteriuria susceptible to:
 Ciprofloxacin 76 (64%)* 34 (36%)* 30 (28%) * < 0.001
 Amikacin 102 (86%)* 55 (58%)* 61 (57%) * < 0.0001
 Amox/clav ND 44 (46%) 44 (41%) NS
 Cefuroxime 51 (43%)* 22 (23%)* 28 (26%) * < 0.01
 Cotrimoxazole 12 (10%)* 27 (28%)*† 49 (46%)† * < 0.001 † 0.01

  1. Only when all strains isolated from a single patient were susceptible to one antibiotic or to a combination susceptibility in this analysis was recognized. When one or more strains were resistant, intermediate susceptible or not examined for a specific antibiotic non-susceptible status was given. Numbers and percentages of patients with susceptible flora relative to all patients with bacteriuria are reported
  2. Amox/clav amoxicillin with clavulanic acid
  3. The * or † character was used to determine which pair of values in the row was compared with a statistical test
