Außer einer nicht behandelten Kontrollgruppe wurde eine zweite Gruppe mit dem als Referenzsubstanz dienenden Gemisch von 300 mg 2-Sulfanilamido-4,5-dimethyloxazol + 60 mg Trimethoprim behandelt.

Der so erhaltene Zahlenwert (Trimethoprimfaktor). ist ein Maß für die Wirkung der erfindungsgemäßen Substanzen im Vergleich zum Trimethoprim.
