Final answer:
Fluoroquinolones and aminoglycosides are oral antibiotics that can be used to treat pseudomonas infections.
Step-by-step explanation:
Pseudomonas infections can be difficult to treat due to their resistance to many antibiotics. However, there are some oral antibiotics that can be effective against pseudomonas. Fluoroquinolones such as ciprofloxacin and levofloxacin are commonly used to treat pseudomonas infections, as they have good activity against the bacteria. Another option is aminoglycosides like gentamicin, which can be used in combination with other antibiotics.
