Gonorrhea is transmitted through sexual contact with the penis, vagina, mouth, or anus of an infected partner. Ejaculation does not have to occur for gonorrhea to be transmitted or acquired. Gonorrhea can also be spread perinatally from mother to baby during childbirth.
What is the transmission route of pulmonary tuberculosis?
tuberculosis is transmitted through the air, not by surface contact. 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 lungs (Figure 2.2). M.
Is tuberculosis can transmitted sexually?
A person who has genital tuberculosis can infect others through sexual contact. The most common means of spreading genital TB can be through blood or lymph. Hence, sexual contact can spread genital tuberculosis.. Genital tuberculosis can spread to any other body organ, once it enters the body.
When is gonorrhea transmitted?
Gonorrhea is spread when semen (cum), pre-cum, and vaginal fluids get on or inside your genitals, anus, or mouth. Gonorrhea can be passed even if the penis doesn’t go all the way in the vagina or anus. The main ways people get gonorrhea are from having vaginal sex, anal sex, or oral sex.
What is the virulence factor of gonorrhea?
Like many Gram-negative bacterial pathogens, N. gonorrhoeae possesses a wide range of virulence determinants, which include the elaboration of pili, Opa protein expression, lipooligosaccharide expression (LOS), Por protein expression and IgA1 protease production that facilitates adaptation within the host.
Is pulmonary tuberculosis transmitted?
Pulmonary TB is caused by the bacterium Mycobacterium tuberculosis (M tuberculosis). TB is contagious. This means the bacteria are easily spread from an infected person to someone else. You can get TB by breathing in air droplets from a cough or sneeze of an infected person.
Is pulmonary TB airborne or droplet?
Mycobacterium tuberculosis is transmitted in airborne particles called droplet nuclei that are expelled when persons with pulmonary or laryngeal TB cough, sneeze, shout, or sing. The tiny infectious particles can be carried by air currents throughout a room or building.
What are the 8 modes of transmission?
Modes of transmission
- Direct. Direct contact. Droplet spread.
- Indirect. Airborne. Vehicleborne. Vectorborne (mechanical or biologic)
What are the 5 basic modes of transmission of infection?
The transmission of microorganisms can be divided into the following five main routes: direct contact, fomites, aerosol (airborne), oral (ingestion), and vectorborne. Some microorganisms can be transmitted by more than one route.
What STD is TB?
Tuberculosis: Frequently Asked Questions. TB, or tuberculosis, is a disease caused by bacteria caused Mycobacterium tuberculosis. It is spread from person to person through the air. TB usually affects the lungs. TB can also affect other parts of the body, such as the brain, kidneys or the spine.

How is Mycobacterium tuberculosis (TB) transmitted?
Mycobacterium tuberculosis. Transmission of TB. M. tuberculosis. is carried in airborne particles, called droplet nuclei, of 1– 5 microns in diameter. Infectious droplet nuclei are generated when persons who have pulmonary or laryngeal TB disease cough, sneeze, shout, or sing. Depending on the environment, these tiny particles can remain
What is gonorrhea and how is it spread?
Gonorrhea is an infection caused by the bacteria Neisseria gonorrhoeae. It is spread during vaginal, anal, or oral sex. A pregnant woman may also pass the infection to her baby during delivery. Anyone who has gonorrhea can pass it on, even without symptoms. Treatment is the only way to get rid of the infection.
How are infectious droplet nuclei generated in tuberculosis (TB)?
Infectious droplet nuclei are generated when persons who have pulmonary or laryngeal TB disease cough, sneeze, shout, or sing. Chapter 2: Transmission and Pathogenesis of Tuberculosis 22 Figure 2.2 Transmission of TB TB is spread from person to person through the air. The dots in the air represent droplet nuclei containing tubercle bacilli.
What happens when you breathe in tuberculosis bacteria?
When a person breathes in TB bacteria, the bacteria can settle in the lungs and begin to grow. From there, they can move through the blood to other parts of the body, such as the kidney, spine, and brain.
