The difference between bronchitis and mycoplasma infection should first be made clear that bronchitis can be caused by a variety of pathogens. The corresponding viral infections of the respiratory system can cause episodes of bronchitis, and bacterial infections can also cause episodes of bronchitis. Mycoplasma infection is a relatively broad term, and mycoplasma infection can cause bronchitis due to mycoplasma, and when the lesions in the lungs are more pronounced, it can cause mycoplasma pneumonia. Therefore, there is a certain possibility of crossover between the two, with mycoplasma infection being relatively clear. When mycoplasma infection is diagnosed, targeted treatment, such as macrolides and respiratory quinolones, needs to be given.
