20 cases of abdominal tuberculosis (TB) were evaluated; from these, 10% with intestinal TB without peritoneal involvement and 90% presenting TB of peritoneal localization. 80% of the patients showed clinical manifestation in other organs. Pleura-lung alterations were found in 83% of the cases after X-ray chest examination. The diagnosis of abdominal TB was based on finding of caseating tuberculoid granuloma (65%), anti-TB therapeutic response (30%) and positive observation of acid-fast bacillus in sputum (5%). The conclusions from this review are that: 1) Patients with chronic illness, negative cultures and clinical evidence of infectious etiology are highly suspicious; 2) Analysis of pathologic specimens was the most accurate diagnostic method; 3) when abdominal TB is suspected a stepwise methodology must be followed to confirm diagnosis; 4) Anti-TB therapy must be started as soon as diagnosis is confirmed.

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 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...
Pulmonary Tuberculosis III
The first classification is based on the development of the disease, and it includes the following categories:
Pulmonary Tuberculosis IV
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...
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...
