  1. The level of growth inhibition was assessed by the average zone of inhibition diameter recorded (4 replicates). ‘++++’ = zone of inhibition ≥ 25 mm; ‘+++’ = zone of inhibition ≥ 20–24 mm; ‘++’ = zone of inhibition ≥ 10–19 mm; ‘+’ = zone of inhibition ≥ 5–9 mm; and ‘-’ = no zone of inhibition. [Well diameter (5 mm) was included]. MIC was defined as the lowest concentration that produced zone of inhibition ≥5 mm in diameter against test organism
