Evolution Of Drug Resistant Mycobacterium Tuberculosis

Once believed to be easily treated and prevented, Tuberculosis (TB) has recently been making a steady comeback. Previous to modern medicine, TB claimed millions of victims, spreading from person to person like wildfire. Around the 17th-18th centuries, the “White Plague” took the lives of 1 in 5 adults (20%) in Europe and North America (Iseman, 1994). However, as technological advances progressed, this seemingly ferocious viral disease became a primal, insignificant thing of the past. But, in the

are substances of medicinal purposes that inhibit the growth of bacteria like tuberculosis and malaria. Antibiotics are used to prevent infections of possibly fatal diseases. The resistance to an antibiotic occurs when a bacterium changes in a way that makes an antibiotic ineffective against a targeted bacterium. There are many causes of antibiotic resistance, some due to prescription methods and some due to evolution. The man who invented penicillin predicted the future resistance to antibiotics

Tuberculosis, an airborne disease, infects people through inhalation of mycobacterium tuberculosis, which is called droplet infection, and is potentially fatal to its victims. (Muller, 2011). Mycobacterium tuberculosis is the causative agent for tuberculosis. There are 19 registered types of mycobacterium that are associated with tuberculosis, which are identified and differentiated by culture of the organism and the disease kills around 1.7 million people each year. Tuberculosis is primarily

Tuberculosis (TB) is caused by the Bacterium Mycobacterium tuberculosis also called tubercle bacilli which is an aerobic non-motile bacillus which are approximately 2-4 micrometers in length and 0.2-0.5 um in width. M. tuberculosis cell is made of peptidoglycan which is attached to galactofuran which in turn is attached to arabinofuran which is finally attached to mycolic acids. Hydrophobic molecules making up Mycolic acids form a lipid layer surrounding the organism therefore influencing permeability

relies on the fitness effects of resistance elements in the absence of antibiotics. Angst and Hall tentatively developed rifampicin-resistant and delicate Escherichia coli in drug-free environment, before measuring the impacts of new resistance components on fitness in antibiotic free conditions. Streptomycin resistance changes had little fitness impacts in rifampicin-resistant genotypes that had adjusts to antibiotic free environment , contrasted with the same genotypes without acclimatization. They

The prevalence of multi-drug resistant tuberculosis has not only impacted India it has impacted other countries like Africa. Multi-drug resistant tuberculosis is when the regular medicine such as isoniazid and rifampicin one of the two anti-tuberculosis drugs used, the resistance can occur either through not following the proper treatment guidelines or from a drug resistant bacteria, tuberculosis can be caused from Mycobacterium Tuberculosis a bacteria that causes tuberculosis which attacks the lungs

Tuberculosis (TB) is caused by the bacterium Mycobacterium tuberculosis, an aerobic non-motile bacillus measuring 3-5µm in length and 0.2-0.6µm in width (Velayati and Farnia., 2012) M. tuberculosis cell wall is made of many lipids including peptidoglycan and mycolic acids. Hydrophobic molecules making up Mycolic acids form a lipid layer surrounding the organism affecting permeability of the cell surface. This layer is responsible for many pathogenic inducing traits of M. tuberculosis by inhibiting

Tuberculosis, also identified as TB, has been around for countless years. In the past, however, the disease was not known, which made it untreatable in most healthcare settings. The evolution of time made it possible to easily detect and manage tuberculosis before people were adversely affected by it. It is a disease that often affects an individual’s lungs, but it can also affect other body parts. The spine, kidneys, bones, and even the lymph nodes may sometimes be affected by the disease. The spread

Tuberculosis: Epidemiology and Nursing Role Tuberculosis has been a persistent threat to the human race as far back as Hippocrates (c.460-c.370 BC). Globally, tuberculosis has infected millions during waves, often killing scores of people at a time, and then receding giving it an almost supernatural quality (Daniel, 2006). In recent history tuberculosis has been recorded in all corners of the world, and currently infects one third of the global population. In 2012, TB was responsible for killing

TUBERCULOSIS Jillian Gasper Kaplan University Abstract Tuberculosis (TB) is a chronic bacterial infection that affects millions of people globally. It is a contagious disease that is spread through the air, and it usually affects the lungs. It is transmitted from person to person through droplets from the respiratory tract of those who are already infected with the disease. Some who are infected with the bacteria that causes TB often exhibit no symptoms, because their immune systems
