Disc diffusion tests are unreliable when looking for co-trimoxazole resistance in B. pseudomallei (they greatly overestimate resistance) and Etests or agar dilution tests should be used in preference.
As probas de disco de difusión non son fiables cando se busca resistencia a co-trimoxazole en B. pseudomallei (sobreestiman en moito a resistencia) e os Etests ou as probas de dilución de ágar son os que se deberían usar preferentemente.
