Which groups of infections can lead to acute episodes of bronchitis?

Acute bronchitis is an inflammation of the bronchial tubes that can occur due to a variety of infectious agents. The correct choice is comprehensive because it includes viral, bacterial, and mycoplasma infections, all of which are known to trigger instances of acute bronchitis.

Viral infections, such as those caused by influenza, respiratory syncytial virus (RSV), and rhinoviruses, are the most common culprits of acute bronchitis. These viruses can damage the bronchial epithelium, leading to inflammation and the classic symptoms of cough, mucus production, and wheezing.

Bacterial infections can also contribute to acute bronchitis, especially if a secondary bacterial infection develops following a viral illness. Common bacterial pathogens implicated in acute bronchitis include Streptococcus pneumoniae and Haemophilus influenzae. Mycoplasma pneumoniae is another atypical bacterium that can cause respiratory tract infections, including bronchitis, particularly in younger populations.

Other options are limited in scope. Fungal infections are not typically associated with acute bronchitis in healthy individuals; they are more often linked to chronic lung conditions or immunocompromised states. Parasitic infections are similarly not a common cause of acute bronchitis, as they tend to
