Which of the following options best describes a common treatment for tuberculosis?

Long-term antibiotics are the cornerstone of tuberculosis (TB) treatment due to the nature of the Mycobacterium tuberculosis bacteria, which are resistant to many forms of treatment and require a specific regimen to effectively eradicate the infection. The typical treatment regimen includes a combination of antibiotics, such as isoniazid, rifampicin, ethambutol, and pyrazinamide, usually for a duration of six months or more. This prolonged course of treatment is essential to ensure that the bacteria are completely eliminated from the body, reducing the risk of developing drug-resistant strains of tuberculosis.

In contrast, the other options listed do not effectively treat tuberculosis. Steroids may be used to manage inflammatory responses or complications related to TB but do not address the infection itself. Oxygen therapy might be utilized in severe cases of respiratory distress but does not treat the underlying infection. Bronchodilators can help ease breathing difficulties, particularly in individuals with co-existing respiratory conditions, but they also do not target the tuberculosis bacteria directly. Therefore, long-term antibiotics remain the primary and most effective treatment strategy for tuberculosis.
