Bacterial conjunctivitis is an infectious condition in which the conjunctiva become inflamed. The infecting organism is most often Staphylococcus aureus.

Viruses are also common causative agents of infective conjunctivitis and it may be clinically difficult to distinguish a viral from a bacterial infection. OTC treatment of any superficial infective conjunctivitis with an antibacterial agent is considered appropriate, as it may help prevent secondary bacterial infection if the condition is of viral origin.
