A microbiological test performed on a swab sample from purulent or mucous secretions found in the conjunctiva (the thin membrane lining the eyelid and the inside of the eye) of the left eye. It aims to isolate and identify the bacteria or fungi responsible for the infection (bacterial or fungal conjunctivitis). This is followed by antibiotic susceptibility testing to select appropriate antimicrobial agents, guiding precise and effective treatment, contributing to rapid healing and preventing complications.
