1 (TMP)/19 (SMX) mg/liter represents the MIC90 for Australian isolates.
2/38 mg/liter represents the susceptibility threshold.
3/57 mg/liter represents the MIC90 for Thai isolates.
Weight-based dosing for patients was as follows: <40 kg (body weight), 160/800 mg q12h; 40 to 60 kg, 240/1,200 mg q12h; and >60 kg, 320/1,600 mg q12h.
