Bacterial eye infection: A bacterial eye infection occurs when bacteria invade any part of the eyeball or its surrounding tissues, including the cornea (clear front surface of the eye) and the conjunctiva (thin membrane lining the outer eye and inner eyelids). A bacterial eye infection symptoms include red eyes, pain, swelling of the eyes, watery eyes, itching, and blurry vision. Some very common eye infections are conjunctivitis, stye (bump on the eyelid), uveitis (inflammation of the uvea-middle layer of the eye), marginal keratitis (inflammation of the cornea), and blepharitis.

Bacterial ear infection: Bacterial ear infection occurs when bacteria infect the outer or middle ear. The most common bacterial strains that cause ear infections are Streptococcus pneumoniae and Haemophilus influenza. Symptoms include ear ache (sharp, sudden pain or a dull, continuous pain), feeling of fullness in the ear, ear drainage, and muffled hearing. Treatment may include over-the-counter painkillers, anti-allergic drugs, antibiotics, and steroids.
