Can you name a bacterium sensitive to ampicillin sulbactam?

Which bacteria are reported as sensitive to ampicillin/sulbactam?

Ampicillin–sulbactam is commonly active against certain Gram-negative and some Gram-positive bacteria that are susceptible to the ampicillin component, especially where sulbactam helps block beta-lactamases. One example of a bacterium that is sensitive to ampicillin/sulbactam is:

- Haemophilus influenzae [1]

Is sensitivity the same for all strains?

No. Susceptibility varies by strain and local resistance patterns, including whether the organism produces beta-lactamases or has altered antibiotic targets. In practice, lab testing (antibiotic susceptibility testing) is what confirms whether a specific isolate is sensitive.
