  • * Escherichia coli was the most common pathogen, with 191 isolates (79% of all isolates). Streptococcal (Strep) species were the second most common type of pathogen, with 18 isolates (7%). There were 10 Klebsiella isolates (4%), nine staphylococcal (Staph) species isolates (4%), and eight Proteus isolates (3%).

  • TMP-SMX, trimethoprim/sulfamethoxazole; NT, not tested; R, resistance; IR, intermediate resistance.
