Animals were housed in a room free from any source of chemical contamination, artificially illuminated and thermally controlled at the Animal House Lab., Pharmacology and Chemistry Research Centre, Misr University for Science and Technology (6th October, Giza, Egypt). After an acclimatization period of 1 week, the animals were divided into four groups (10 rats/group) and housed in filter-top polycarbonate cages (five rats per cage). All animals have received human care in compliance with the guidelines of the Animal Care and Use Committee of the Pharmacology and Chemistry Research Centre (6th October City, Giza, Egypt). Infection Model Circular Excision Wound Model For the evaluation of the antibacterial activity, each rat was undergo anaesthesia by intraperitoneal injection of a combination of 10% ketamine hydrochloride (50 mg/kg) and 2% xylazine hydrochloride (5 mg/kg). The hair of the dorsal back of animals was shaved. For sterilization conditions, the sites of surgery were sanitized by povidone iodine followed by 70% ethanol solution. Circular incision was made on the dorsal inter-scapular region of
