Which of the following is NOT one of the main pathogens covered by Vigamox?

Vigamox is an antibiotic eye drop containing moxifloxacin, which is primarily used to treat bacterial conjunctivitis. The main pathogens that Vigamox is effective against include common ocular pathogens, particularly those associated with bacterial infections of the eye. These include Staphylococcus aureus, Streptococcus pneumoniae, and Haemophilus influenzae, which are well-known contributors to ocular infections.

E. coli, while a significant pathogen in many types of infections, is not commonly associated with eye infections and is therefore not one of the main pathogens that Vigamox targets. This makes it the correct choice as the one that is NOT covered by Vigamox. The focus of Vigamox on specific ocular pathogens reflects its formulation designed to address conjunctivitis and other eye-related bacterial infections effectively.
