The Impact of the Tuberculosis Vaccine Abstract Tuberculosis is one of the most infectious diseases in the world. With almost one third of the world infected with this virus, people are striving to help prevent the spread of this disease (NIAID, 2001). One prevention technique for tuberculosis is the BCG (Bacillus of Calmette and Guerin) vaccine. In the early twentieth century Calmette and Guerin worked together to isolate a strain of the disease creating the first BCG vaccine. Throughout the century the scientists improved the BCG vaccine and today there are several different strains of the vaccine available.
Tuberculosis and Its Pathogenic Processes Abstract Tuberculosis is the most deadly infectious disease in the world and is transmitted either by the inhalation of M. tuberculosis, M. bovis, M. africanum, M. microti, or M. avium bacteria, i.e. the respiratory route. It can also be transmitted via consumption of infected tissues. The bacteria propagate in a five- stage process if the body cannot manage to fight off the disease, meaning that people who are immunocompromised or near those who are infected are more at risk to get an active infection. TB can spread to lymph nodes, through the bloodstream and throughout the body.
Tuberculosis is primarily a bacterial infection of the respiratory system. If bacteria, viruses, or fungi enter the lungs and become established there, they could cause several dise... ... middle of paper ... ...he benefits that medical technology has brought to society over centuries as well as an awareness that the fight against bacteria is by no means over. The recognition that there are several forms of drug-resistant bacteria today should propel future generations to rededicate efforts to eradicate them. Further research and observations should be made in order to help suppress deadly strands of tuberculosis. TB Treatment 6 References: Carlomagno, Cathy.
Drug Resistance Rising Among Mycobacterium tuberculosis Cases Abstract Drug resistance has been increasing among patients infected with Mycobacterium tuberculosis. Previous miracle drugs that were used in the 1950s have now been proven useless in many cases simply because the bacteria are not susceptible to antibiotics such as isoniazid, rifampin, pyrazinamide, etc. when they are taken. This pathogen is easily transmitted through air and has the capability of attacking the respiratory system and creating fatal consequences if not treated properly. A lot of people who contribute to the antibiotic resistant statistics are those that do not take medication accordingly.

Tuberculosis has been around for a very long time it used to be called “consumption” because the infection would consume who ever had the disease. Tuberculosis is sometimes called TB for short. Tb is a very contagious disease that is caused by bacteria that takes over the lungs. TB can spread all over the body and affect the brain and the spine. The type of bacteria that causes this infection is
Bacteria are becoming resistant to antibiotics. Doctors consistently change their patient’s medicine because bacteria keep becoming resistant to antibiotics. Vaccines help prevent some types of meningitis, but not all of them. Bacteria reproduce really easily and rapidly, so a disease can spread really quickly. Bacteria Bacteria are living things.

Incidence of Tuberculosis, United States Many researchers attribute the sharp increase in the early 1990s to the spread of acquired immunodeficiency syndrome (AIDS). People with AIDS have weakened immune systems and are particularly susceptible to contagious diseases such as tuberculosis. Poorly supervised treatment of tuberculosis also led to an increase in drug-resistant strains of the bacteria that cause tuberculosis, furthering the spread of the disease. Renewed emphasis on control and prevention has brought the incidence of tuberculosis to record low levels.
An attack on the lungs occur when the person breaths in the air, thus the bacteria is entered. The human body may consume bacteria that cause TB. Our immune system usually can prevent illness. Because of this, physicians distinguish between latent tuberculosis and active tuberculosis. Signs and symptoms of active TB is: 1) Unintentional 4) Chills 7) Fever 2) Weight loss 5) Loss of appetite 3) Night sweats 6) Fever A healthy immune system can often fight the bacteria of TB, but if the immune system defense is low the mount is not effective.
