Abstract:
Vaccines against smallpox are known to have cross-protective activity against monkeypox, and smallpox and monkeypox infections are believed to generate permanent immunity. Nevertheless, there are scarce data about the possibility of reinfection or reactivation. Recently, a case of apparent monkeypox reinfection has been reported. We present a suspected case of second episode of monkeypox in a healthy and previously vaccinated man, with a confirmed primary monkeypox infection occurring three months before the second confirmed presentation.

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 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.
