P, unclear inhibition zone/many colonies in the inhibition zone; V, very unclear inhibition zone. Exactly 50 μL of a 0.1 mM solution of each compound dissolved in 1:9 DMSO/MeOH was added to 9 mm wells in agar media (Standard I Nutrient Agar, Serva, or Mueller Hinton II Agar, Becton, Dickinson and Company). Inhibition zones were read after incubation at 37 °C for 24 h. M. vaccae was incubated at 37 °C for 44 h.

Ciprofloxacin was tested at 5 μg/mL in H₂O.

Ciprofloxacin was tested at 1.66 μg/mL in H₂O.

Ciprofloxacin was tested at 0.33 μg/mL in H₂O.
