Uropathogens susceptible to selected agents, stratified by species and TMP-SMX susceptibility

AgentNo. (%) of isolates susceptible to alternative agent
E. coliNon-E. coli, TMP-SMX susceptible (n = 17)
TMP-SMX susceptible (n = 71)TMP-SMX resistant (n = 15)
Fluoroquinolones71 (100)a13 (86)a17 (100)
Gentamicin71 (100)b12 (80)b17 (100)
Ampicillin-sulbactam64 (90)c11 (72)c10/12 (83)
Cefazolin70 (99)14 (93)11/12 (92)

  • a TMP-SMX resistance was significantly associated with resistance to the fluoroquinolones (P = 0.008) among the E. coli isolates.

  • b TMP-SMX resistance was significantly associated with resistance to gentamicin (P = 0.001) among the E. coli isolates.

  • c MP-SMX resistance exhibited a borderline statistically significant trend for resistance to ampicillin-sulbactam (P = 0.09) among the E. coli isolates.
