Question

Prompt 2: Select one of the bacteria discussed in module 11 and discuss the following: (USLO 11.1, 11.2, 11.3, 11.4, and 11.5) o Disease caused O Mode of transmission o Virulence factors O Diagnostic methods

any of the following:Staphylococcocal Diseases, Mycobacterium ,Clostridium and Bacillus, Pseudomonas Bacterial Diseases.

Answer 1

Mycobacterium bacterial disease.

1. Disease caused - tuberculosis by mycobacterium tuberculosis .

2. Mode of transmission- M. tuberculosis is carried in airborne particles, called droplet nuclei.

Transmission occurs when a person inhales droplet nuclei containing M. tuberculosis, and
the droplet nuclei traverse the mouth or nasal passages, upper respiratory tract, and bronchi to reach the alveoli of the lung.

3. Virulence factor - PDIM and PLG are the major virulence factors of mycobacteria. PDIM and PGL are molecules required for bacterial duplication during the acute phase of infection .

4. Diagnostic method- there are two main tests by which we cam detect whether a person is infected or not.with M. tuberculosis: the tuberculin skin test (TST) and the IFN-γ release assays (IGRAs)
