Moraxella catarrhalis

A species that is a frequent cause of upper and lower respiratory tract infections, including otitis media in children and bronchitis and pneumonia in the elderly. It is resistant to beta-lactam antibiotics such as most penicillins, but can be treated with many cephalosporins, macrolides, and sulfa drugs.

Goldblatt et al showed that topical ofloxacin was more effective than oral amoxicillin/clavulanate when S aureus or P aeruginosa was present (although the two were equal when S pneumoniae, M catarrhalis, or H influenzae was present).
That dose, as we now know from double-tap eradication studies, is likely to fail to eradicate 25 to 40% of even the beta-lactamase-negative strains, and it appears to be no better than placebo against beta-lactamase-producing strains of H influenzae and M catarrhalis.
Sulfacetamide drops are bacteriostatic against H influenzae, M catarrhalis, and most pneumococci, which are common organisms seen in acute otitis media and chronic otitis media with effusion.
