[Outcomes of pulmonary tuberculosis in patients without bacterial isolation (according to sputum microscopy data)]
Abstract:
The composition, the outcomes of treatment and a follow-up were analyzed in 4 954 first detected adult patients with pulmonary tuberculosis and the baseline negative results of a sputum test for acid-resistant mycobacteria, with the involvement of not more than a lobe. The basic course of therapy yielded clinical and X-ray effects in 83.6% of cases. In the late period of a follow-up, the rate of clinical cure was 93.4%; that of death from tuberculosis, formation of chronic incurable forms of the process, and recurrent tuberculosis was 1.4, 0.9, and 0.9%, respectively. Treatment interruption, multidrug resistance, social disadaption of patients, and severe comorbidity were responsible for the poor outcomes of timely detected tuberculosis.

The first classification is based on the development of the disease, and it includes the following categories:
Pulmonary Tuberculosis V
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the progression...
Pulmonary Tuberculosis II
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
