Acute bronchitis is usually caused by viruses; which bacterial pathogens are commonly implicated?

• A. Viruses; Bacterial
• B. Bacteria; Viruses
• C. Fungi; Bacteria
• D. Parasites; Viruses

Answer: (A)

Acute bronchitis is predominantly viral in origin, so antibiotics are not routinely needed. The role of bacteria is minimal in most cases; when bacterial involvement does occur, it’s usually due to uncommon or atypical pathogens such as Bordetella pertussis, Mycoplasma pneumoniae, or Chlamydophila pneumoniae, and these are not as common as viruses. So the statement that viruses are the usual cause and bacteria are not commonly implicated fits the typical clinical picture. The other options would imply bacteria or other organisms as the main culprits, which doesn’t align with how acute bronchitis most often presents.
