Pulmonary tuberculosis. Light micrograph of a section through lung tissue from a patient with tuberculosis (TB),showing tubercles (lesions,black) containing bacteria. Pulmonary TB is caused by infection with Mycobacterium tuberculosis bacteria,which are spread by coughing and sneezing. The bacteria create primary tubercles,nodular lesions of dead tissue and bacteria,when inhaled into the lungs. Pulmonary tuberculosis may be symptomless,and may recur at periods when the patient's immune system is weakened. Symptoms of the active disease include fever,weight loss and the coughing up of blood. Treatment is with long-term antibiotics | |
