How many pathogens does Vigamox kill?

Vigamox, which contains the active ingredient moxifloxacin, is a broad-spectrum antibiotic used primarily to treat bacterial conjunctivitis. The effectiveness of this antibiotic is particularly relevant to understanding its action against various pathogens.

Moxifloxacin works by inhibiting bacterial DNA gyrase and topoisomerase IV, enzymes crucial for bacterial DNA replication and cell division, leading to the death of the bacteria. The range of pathogens that Vigamox is effective against includes common bacteria associated with eye infections, particularly the following types: gram-positive bacteria, gram-negative bacteria, and atypical pathogens.

The correct answer indicates that Vigamox targets 13 different pathogens. This includes a range of strains from both categories, demonstrating its ability to combat a comprehensive set of bacteria typically responsible for conjunctivitis. The knowledge of specific pathogens and their susceptibilities is essential for effective treatment with antibiotics like Vigamox.

The other options suggest lower numbers, which would underrepresent the breadth of pathogens covered by moxifloxacin and inaccurately express its effectiveness in treating infections. Thus, understanding the correct number of pathogens helps reinforce the drug's significance in a medical context for treating bacterial infections effectively.
