What antibiotic is commonly used to treat listeriosis?

The commonly used antibiotic for treating listeriosis is Penicillin G. This antibiotic is particularly effective against Listeria monocytogenes, the bacterium responsible for the infection. Penicillin G works by inhibiting the synthesis of bacterial cell walls, which is crucial for the bacteria's survival and replication.

In cases of listeriosis, especially in severe or systemic infections, Penicillin G is preferred due to its effectiveness against the specific bacteria involved. While other antibiotics, such as tetracycline and ciprofloxacin, may be effective against a range of bacterial infections, they are not the first-line treatments for listeriosis. Enrofloxacin, although used in veterinary medicine, is not typically applicable or recommended for treating listeriosis in humans. Understanding the specific bacteria and their susceptibility to different antibiotics is crucial for effective treatment.
