The mechanism by which the bacteria causes symptoms of blepharitis is not fully understood and may include direct irritation of bacterial toxins and/or enhanced cell-mediated immunity to S. aureus. Staphylococcal blepharitis is caused by an infection of the anterior portion of the eyelid by Staphylococcal bacteria. [14]
Polymyxin B/trimethoprim, sold under the brand name Polytrim is an antimicrobial solution for topical ophthalmic use in the treatment of acute bacterial conjunctivitis and blepharoconjunctivitis. [1] In 2022, it was the 252nd most commonly prescribed medication in the United States, with more than 1 million prescriptions. [2] [3]
The epidemic nature of this bacteria has been seen in the high frequency of “control” subjects from the affected areas of Brazil that have or had recently had conjunctivitis. These control subjects did not develop Brazilian Purpuric Fever, and therefore were probably not carrying the more dangerous BPF clone of H. influenzae biogroup aegyptius.

Bacterial conjunctivitis usually resolves without treatment. [3] Topical antibiotics may be needed only if no improvement is observed after 3 days.

Moxifloxacin is an antibiotic, used to treat bacterial infections, [4] including pneumonia, conjunctivitis, endocarditis, tuberculosis, and sinusitis. [4] [5] It can be given by mouth, by injection into a vein, and as an eye drop.
Chloramphenicol is an antibiotic useful for the treatment of a number of bacterial infections. [5] This includes use as an eye ointment to treat conjunctivitis. [6] By mouth or by injection into a vein, it is used to treat meningitis, plague, cholera, and typhoid fever. [5]
Active bacterial infections may be treated with a topical antibiotic or a combination antibiotic-steroid eye drop, such as tobramycin/dexamethasone (Tobradex). [1] An oral tetracycline antibiotic (such as doxycycline ) may be used in systemic or particularly severe/intractable infections.
