Mycobacterium tuberculosis Introduction Mycobacterium tuberculosis has been present in the human population for thousands of years; fragments of the spinal column from Egyptian mummies from 2400 BCE show definite pathological signs of tubercular decay. Called "consumption," tuberculosis was recognized as the leading cause of mortality by 1650. Using a new staining technique, Robert Koch identified the bacterium responsible for causing consumption in 1882. While scientists finally had a target
Introduction Tuberculosis (TB) is the most common disease worldwide which caused by Mycobacterium tuberculosis. With close to 10 million new cases per year, and a pool of two billion latently infected individuals, control efforts are struggling in many parts of the world (The bacteria usually attack the lungs, but they can also damage other parts of the body (Comas and Gagneux, 2009). It is important for a nurse to understand how tuberculosis develops, how to diagnosis, treatment, and prevent. Myobaterium
Introduction Drug resistance in mycobacterium tuberculosis (TB) has become a severe global health threat. The fight against TB is now facing major challenges due to the appearance of Multi-Drug Resistant Tuberculosis (MDR-TB) and more recently, the virtually untreatable Extensively Drug Resistant Tuberculosis (XDR-TB). MDR-TB are strains that are resistant to both top first-line drugs, Isoniazid and Rifampin, while XDR-TB are MDR-TB strains that are also resistant to any fluoroquinolone and one or
primarily Hispanic and Latinos with tuberculosis. The goal is to teach immigrants on how to prevent the spreading of TB and how to prevent the disease. An estimated one third of the world 's population is infected with Mycobacterium tuberculosis. In 2012 there were 9,975 cases of TB reported and of those cases 28% where Hispanic or Latino. This respiratory disease is the most common in the lungs (World Health Organization, 2014). The brain which causes tuberculosis meningitis, genitourinary TB, gastrointestinal
Tuberculosis Introduction Tuberculosis (TB) is an ancient disease, with evidence found in human remains dating back over 9000 years, to the Neolithic era. 1 It was identified and described by Hippocrates as early as 460BC, and continued to be documented in such places as ancient Rome, Egypt, India and China. 2 3 4 5 The disease can be caused by different mycobacterium such as Mycobacterium bovis, M. africanum, M. canettii, M. microti, and most commonly, M. tuberculosis; although the five are highly
[Silicosis and Silicate Disease Committee 1988]. This fibrotic condition of the lung is called silicosis. If the nodules grow too large, breathing becomes difficult and death may result. Silicosis victims are also at high risk of developing active tuberculosis [Myers et al. 1973; Sherson and Lander 1990; Bailey et al. 1974]. A worker's lungs may react more severely to silica sand that has been freshly fractured (sawed, hammered, or treated in a way that produces airborne dust) [Vallyathan et al. 1988]

Tuberculosis (TB), a deadly contagious disease is among the three major infectious killers that causes high mortality and morbidity, worldwide.1 Tuberculosis infects one-third of the world's population with an estimated 8.7 million new cases and 1.4 million deaths every year (WHO, 2012)2. Tuberculosis prevention has become more complex due to increased resistance against different antibiotics including rifampicin.3 TB is a socio-economic disaster that is occurring worldwide, especially in Asia
Select, Attach and Describe Tuberculosis in the 1980s were evident through the several years of rising case accounts to its highest point in 1992 this is alarmingly high because the disease travels through the air. As a result, it affects more people, worsening the impact of this disease. It also the impact the lack of education; corrupt living conditions, famine, deprived usage of health care, shortage vaccination charges and poor treatments all contribute to high tuberculosis cases consequence affecting
The problem: Tuberculosis has been known to mankind since ancient times. Earlier this disease has been called by numerous names including ‘consumption’ (because of the severe weight loss) and ‘the white plague.’ Mycobacterium tuberculosis (the bacteria that causes TB), existed 15,000 to 20,000 years ago. In the 18th century in Western Europe, tuberculosis reached its peak with a occurrence as high as 900 deaths per 100,000.2 What is tuberculosis (TB disease)? Tuberculosis is a contagious airborne
Introduction: Tuberculosis is an infectious disease which causes millions of death in humans. In India approximately 500,000 deaths occurs now and then. TB is an air borne disease which is caused by Mycobacterium tuberculosis. Apart from M. tuberculosis, there are many strains of Mycobacterial species like M. bovis , M .africanum , M. microti, M. caprae , M. pinnipedi i, M. canetti and M. mungi. Together these species are known to be M. tuberculosis complex. The main target of tuberculosis is the lungs
Worldwide Tuberculosis is caused by M.bovis and M.africanum, in addition to M.tuberculosis. This is likely due to closer interactions between people and livestock, another host for the organisms. Transmissions to humans from susceptible animal species and their products like milk is also possible. It affects lungs and respiratory tract. With the advent of the AIDS epidemic, there has been a steady yearly increase in the number of global TB cases. In the United States, this disease mostly occurs among
FAST FACT OF BOVINE TUBERCULOSIS What is bovine tuberculosis and what causes it? • Bovine tuberculosis (TB) is a chronic and debilitating disease of animals caused by bacteria called Mycobacterium bovis, (M.bovis) which is closely resembled to the avian and human tuberculosis causing bacteria. This disease is characterized by causing general state of illness, coughing and death. • Cattle and buffalo are the main hosts of the bacteria. • The name Tuberculosis derives from ‘tubercles’, which are present
Tuberculosis or TB is an airborn infection caused by inhaled droplets that contain mycobacterium tuberculosis. When infected, the body will initiate a cell-mediated hypersensitivity response which leads to formation of lesion or cavity and positive reaction to tuberculin skin test (Kaufman, 2011). People who have been infected with mycobacteria will have a positive skin test, but only ones who have active TB will show signs and symtoms. Basic signs and symptoms include low grade fever, cough with
Tuberculosis or known as TB remains a leading cause of morbidity and mortality in the world, especially in developing countries. A combination of factors including high costs, limited resources and the poor performance of various diagnostic tests make the diagnosis of TB difficult in developing countries. According to Centers for Disease Control and Prevention (2014), one third of the world’s population is infected with tuberculosis. In 2012, nearly nine million people around the world become sick
Tuberculosis as (TB) is caused by Mycobacterium tuberculosis. It is slow growing bacteria that thrive in areas of the body that are rich in blood and oxygen, such as the lungs. Tuberculosis develops when Mycobacterium tuberculosis bacteria are inhaled into the lungs. The infection usually stays in the lungs, but the bacteria can travel through the bloodstream to other parts of the body. Symptoms of active tuberculosis in the lungs begin gradually and develop over a period of weeks or months. You
Throughout many years tuberculosis has atrociously affected the lives of many people. Many have suffered a horrible death due to this horrid disease. Tuberculosis is a highly contagious disease due to mycobacterium tuberculosis, which initiated about one hundred fifty million years ago. Skeletal abnormalities typical for tuberculosis were found in Egyptian mummies back in 2400 BC. In ancient Greece the Greeks seemed very familiar with tuberculosis only they called it Phtisis. Many years later a
Transmission Tuberculosis is an air-borne disease, hence, it can be passed from an infected person to a healthy individual through coughing, sneezing and other salivary secretions. Tuberculosis is caused by the transfer of Mycobacteriun Tuberculosis (M. Tuberculosis) also known as Tubercle Bacillus, a small particle of 1-5 microns in diameter, due to the small size, when an infected person sneezes or coughs, about 3,000 particles are expelled. M. Tuberculosis responsible for tuberculosis is able to
Tuberculosis Prevention There are several ways to prevent tuberculosis. One is to control existing infections from those infected including people, pets, and cows. Unfortunately, more than 1/3 of the population has tuberculosis, making it hard to contain every case of tuberculosis. The BCG vaccine exists, but it is not very useful in countries like the US. The body’s defenses against tuberculosis are effective but fail once the immune system becomes suppressed. Antibiotics can be used to help
Tuberculosis (TB) is a transmittable and often severe airborne disease, an infection caused by a bacteria known as Mycobacterium tuberculosis (Mtb). TB usually affects the lungs, but it also can affect any other organ of the body. It is usually treatable with a scheduled routine of medicine taken for 6 months to 2 years, the length of treatment is conditional on the type and severity of the infection ( WHO. October 2015). This usually happens when a person breathes in the contaminated air, in which
