[Non-bacterial recurrent respiratory tuberculosis]
Abstract:
The diagnostic and clinical features of recurrent respiratory tuberculosis with negative sputum tests and the efficiency of its therapy were studied in 98 patients. Such recurrences were found to form 30% of all the recurrences. They were more frequently detected by referral rates. Due to difficulties in X-ray diagnosis, the activity of a process should be previously evaluated in patients before their registration. The timely detection of a relapse requires a longer (3-4 years) post-treatment follow-up in a group of cured tuberculosis. The proportion of late relapses was twice higher than that of early relapses occurring after the treatment recommended by the WHO. The vast majority of patients were found to factors, mainly social, that increase the risk of (recurrent) tuberculosis. Patients with alcoholism require compulsory treatment. The efficiency of therapy for abacillary relapses was less than that of therapy for the same processes in first detected patients.

Pulmonary Tuberculosis I
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.

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...
