In terms of differences, eukaryotic cells are much larger and more complex than prokaryotic cells. On average, a typical eukaryotic cell is about 1,000 X larger in volume than a typical prokaryotic cell.
This means both drugs (amoxicillin and penicillin) can treat a wide variety of infections. However, unlike amoxicillin and penicillin, the routinely prescribed drug, metronidazole, has a more selective action towards anaerobic bacteria. These bacteria are the ones causing the signs and symptoms of bacterial vaginosis.
âOne type of bacterial meningitis has now become resistant to an antibiotic weâve used for years, which is penicillin,â says Nigrovic. Fortunately, other antibiotics are still effective treatments for meningitis. â Vancomycin works against many bacteria that are not killed by other antibiotics,â says Vigrovic.
