Mycoplasma is different from other bacteria because it does not have cell walls. Many antibiotics, such as penicillin, weaken the cell walls and kill the bacteria. Because Mycoplasma does not have cell walls, many antibiotics cannot kill it. Symptoms of pneumonia due to pneumonia Mycoplasma are generally mild, and include low-grade fever, fatigue, sore throat, and cough. The infection is sometimes referred to as "pedestrian" pneumonia, which is a non-medical term for mild pneumonia that does not require bed rest or hospitalization. Some are still in good enough condition to go to work and participate in other daily activities. However, pneumonia Mycoplasma sometimes causes more severe pneumonia that requires hospitalization. There are no symptoms in patients with urinary and genital infections of many Mycoplasma, especially in women. If symptoms are present, they are similar to those of Chlamydia's urine and genital infections and depend on gender and location of infection.
