What bacteria is killed by flucloxacillin?

I'm curious to know, which specific bacteria does flucloxacillin effectively eliminate? Is it a broad-spectrum antibiotic targeting a wide range of bacterial strains, or does it have a more narrow focus on certain types of infections? Could you provide a concise overview of the bacterial species that flucloxacillin is known to eradicate, and perhaps also mention any limitations or exceptions to its efficacy?
