Bacterial conjunctivitis is a common type of pink eye, caused by bacteria that infects the eye through various sources of contamination. The bacteria can be spread through contact with an infected individual, exposure to contaminated surfaces or through other means such as sinus or ear infections.

Bacterial conjunctivitis usually produces a thick discharge or pus and can affect one or both eyes.

As with any bacterial infection, antibiotics are required to eliminate the bacteria. Treatment of bacterial conjunctivitis is typically accomplished with antibiotic eye drops and/or eye ointments. The treatment usually takes from one to two weeks, depending on the severity of the infection.
