What kind of bacteria is conjunctivitis?

Conjunctivitis, commonly known as pink eye, can be caused by various types of bacteria, with the most common being Staphylococcus aureus, Streptococcus pneumoniae, and Haemophilus influenzae. These bacteria can lead to inflammation of the conjunctiva, the membrane covering the eye and inner eyelid. Conjunctivitis can also be viral or allergic in nature, but bacterial conjunctivitis is characterized by symptoms such as redness, swelling, and discharge from the eye. Proper diagnosis and treatment are essential to prevent complications and spread.
