Abstract:
Toxoplasmosis is a common zoonotic infection with various transmission mechanisms and wide distribution worldwide. Its probability of causing disease is related to alterations in the immune system as well as the parasite’s virulence. This study presents four cases of patients from rainforest areas in Colombia who did not have any known immunosuppression but do have a diagnosis of toxoplasmosis with pulmonary involvement, confirmed by serology. One of them also developed hypoxemic ventilatory failure and myocarditis. This outbreak of toxoplasmosis occurred in military personnel after coming into contact with common sources of exposure in the Colombian Amazon during a military training exercise. This article includes the diagnostic process, clinical manifestations, treatment, and importance of the parasite’s genotypic variants.

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 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 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...
Transmission-based Precautions II: Airborne and Protective Environment
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...
Pulmonary Tuberculosis III
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...
