What Bacteria Cause Conjunctivitis (Pink Eye)
Bacterial pink eye, also known as bacterial conjunctivitis, is an infection that causes inflammation of the conjunctiva, which is the thin tissue that covers the whites of the eyes and lines the inside of the eyelids. It is caused by bacteria entering the eye and can be highly contagious.
Here are some of the bacteria that can cause conjunctivitis:
- Haemophilus influenzae
- Streptococcus pneumoniae
- Moraxella catarrhalis
- Staphylococcus aureus
- Neisseria gonorrhoeae
These bacteria can infect and inflame the conjunctiva, which is the clear tissue that covers the white part of the eye and the inner surface of the eyelids. Bacterial conjunctivitis can be spread through contact with someone who has the infection, contact with objects that a person with the infection has used, or contact with respiratory droplets from coughs or sneezes. It can also occur due to changes in the bacteria that naturally live on the conjunctiva.
The symptoms of bacterial conjunctivitis are similar to those of viral conjunctivitis but may also include thick green or yellow discharge that causes the eyelids to stick together, swelling of the eye surface, eyelid swelling and pain, and decreased vision. If you suspect you have bacterial conjunctivitis, it is important to consult with a healthcare professional for an accurate diagnosis and appropriate treatment. They will be able to provide guidance on whether home remedies or over-the-counter medication may be appropriate in your specific case.
Medication dosing may be affected by many factors. Check with your health care professional about dosing for your individual situation. Side effects can occur. Check with your health care professional or read the information provided with your medication for side effect information.
