The main difference between mycoplasma infection and mycoplasma pneumonia is that the latter refers to mycoplasma infections in the lungs, while the former includes not only lung infections, but also infectious lesions that may be found in the bronchial tubes, urinary tract, and other areas. Mycoplasma is a specific pathogen that can cause infections in the body, especially in the respiratory tract. Mycoplasma infections are broader in scope compared to Mycoplasma pneumonia, not only lung infections, but also bronchitis or genitourinary infections, for example. Thus, mycoplasma infection includes mycoplasma pneumonia, which is a more specific diagnosis, referring specifically to infectious diseases of the lungs.
