Each assay was conducted in duplicate, and inhibition zones were categorized as follows: Zones of inhibition exceeding 4 mm were categorized as strong inhibition (+ + +), those measuring between 2 and 4 mm were considered intermediate inhibition (+ +), while zones smaller than 2 mm were regarded as weak inhibition ( +), with (-) signifying the absence of any discernible zone of inhibition [34]
