Tuberculosis: The Life Cycle Of Pathogens

A pathogen is anything that causes disease such as:
• Bacteria
• Virus
• Fungi

Organisms that cause disease can variety the ordinary cold to food poisoning to meningitis. They can spread in various ways such as by contacting with body fluids, consumption of undercooked food, or swimming in dirty water. In many countries surveys have took place to see the amount of disease spread by waterborne pathogens. One of the most way pathogens are spread is through personal contact.

The Life Cycle Of Tuberculosis
TB, tuberculosis spreads when a person is affected by this disease such as coughs or sneezes and the air is inhaled by another. A person with tuberculosis will suffer the following 5 stages:
Step 1: On set (1-7 days)
The bacteria are gasped in a process of air and overcome by alveolar macrophages. In some cases the bacteria’s are able to reproduce and the new pledge can harm the victim. Furthermore, Tuberculosis spreads when the mycobacterial enters alveolar mycobacterial.

Step 2: Cooperation (7-21 days)
If the bacteria does not die in the early stage, the bacteria can reproduce and until the macrophage burst. The bacteria will enter the alveolar macrophage. In addition the macrophage combine with blood and it will engulf the bacteria in an independent manner.

Step 3: Initial Caseous Necrosis (14-21 days)
Moreover, the next process of this disease starts when the reproduction of the bacteria slows. As the bacteria reproduce, the growth slows because they kill the surrounding and goes out of the cell to spread within them. In this state the bacteria can no longer reproduce but they can stay alive.

Step 4: Tissue Damaging and Macrophage Starting Response (After 21days...

... infection and virus replication occurs in 6 main steps.
1. Adsorption - virus binds to the host cell.
2. Penetration - virus injects its genome into host cell.
3. Viral Genome Replication - viral genome replicates using the host's cellular machinery.
4. Assembly - viral components and enzymes are produced and begin to assemble.
5. Maturation - viral components assemble and viruses fully develop.
6. Release - newly produced viruses are expelled from the host cell.

Conclusion
Finally, Tuberculosis spreads by micro-bacterium which is contagious. It spreads by victim who spits coughs, sneezes or shouts, the bacteria enter the body of others. On the other hand, HIV/AIDS spreads through unprotected sex if one partner suffers this virus. Even if one drop of the fluids such as semen vaginal fluid or blood enters the partners body, this virus will eventually affect them.
