Mycobacterium Tuberculosis
This case study considers a 63-year old Asian male diagnosed with pulmonary tuberculosis due to drug-sensitive Mycobacterium tuberculosis.
The patient is in the high risk group as his age, gender and ethnicity are risk factors for tuberculosis. The immune system of the elderly is often compromised (National Health Service, 2012). The patient’s age suggests a weak immune system, increasing his susceptibility to M.tuberculosis.
Individuals originating from countries where tuberculosis is prevalent are at a higher risk of developing active tuberculosis (National Health Service, 2012). Tuberculosis is still highly prevalent in Asia as The World Health Organisation (2012), states “Of the estimated 9 million people

This trend was not reflected with gender as, according to the same Public Health England (2014) report over half of the tuberculosis cases in 2013 were male. Figure 2, taken from a report by the World Health Organisation (2014), shows that estimated tuberculosis incidence in South-East Asia has remained very high from 1990-2013. Baring Africa, South-East Asia has the highest incidence rate from 1990-2013, however the Western pacific has shown a significant decrease in its incidence rate, showing that tuberculosis is still highly prevalent in certain parts of Asia.
PATHOGENESIS
As stated by Greenwood et al., (2002), the lung is often the location of initial infection. The tubercle bacilli, consumed by macrophages in the alveolar, replicate forming the initial lesion called the Ghon focus. The resulting primary complex formed includes the Ghon focus and enlarged hilar lymph nodes. The nodes contain further Ghon foci which develop due to bacilli being transported by phagocytic cells. Additionally, bacilli are propagated to many organs, tissues and other parts of the lung by the blood and lymph system.
However, not all bacillus are destroyed during the immune response. Some survive within the macrophage, remaining dormant and can later cause a post-primary disease. In most cases, the primary complex is destroyed, nonetheless, on rare occurrences a contagious foci develops and causes the
Tuberculosis is caused by the bacteria “Mycobacterium Tuberculosis” and is mainly causes infection of the lungs (WHO, 2016). Its mode of transmission is airborne, so it can be passed on by inhalation of airborne droplets which carrying the bacteria, when an infected patient coughs, sneezes, or spits the TB germs into the air (WHO, 1026). Among the symptoms of active TB are: cough with sputum and blood, chest pains, weakness, fever and night sweats (WHO, 2016). Most at risk to get the TB infection are people with weakened immune system such as people who are suffering from chronic diseases such as diabetes mellitus, severe kidney disease, silicosis and especially HIV infection (CDC, 2016). Children and Tobacco users are also at greater risk to fall ill with TB.
Tuberculosis is a disease of an infectious nature caused by a bacterium known as mycobacterium tuberculosis. The disease spreads through the air. People with the disease can spread it to susceptible people through coughing, sneezing, talking or spitting. It mainly affects the lungs and other parts such as the lymph nodes and kidneys can also be affected. The symptoms for TB are fatigue, coughing, night sweats, weight loss and fever. One third of the population of the world is affected with mycobacterium tuberculosis. The rate of infection is estimated to be one person per second. About 14 million people in the world are infected with active tuberculosis. Drug resistant TB has been recorded to be a serious public health hazard in many countries. Resistant strains have developed making it difficult to treat the disease. TB has caused millions of death mainly in people living with HIV/AIDS ADDIN EN.CITE Ginsberg19981447(Ginsberg, 1998)1447144717Ginsberg, Ann M.The Tuberculosis Epidemic: Scientific Challenges and OpportunitiesPublic Health Reports (1974-)Public Health Reports (1974-)128-13611321998Association of Schools of Public Health00333549http://www.jstor.org/stable/4598234( HYPERLINK l "_ENREF_3" o "Ginsberg, 1998 #1447" Ginsberg, 1998). The World Health Organization came up with the DOTS (Directly Observed, Therapy, Short course) strategy. The approach involves diagnosing cases and treating patients with drugs for about 6-8
Tuberculosis is considered to be another surfacing disease. According to the Institute of Medicine, they believe the sole reason of the resurgence of tuberculosis is the increase in immunosuppressed populations. In industrialized countries, peoples
Tuberculosis (TB), which is brought on by contamination with an individual from the Mycobacterium tuberculosis complex, is a noteworthy reason for incapacity and passing in numerous parts of the world. The frequency (recently reported cases) of tuberculosis in Louisiana is near the normal occurrence in the United States. . In 2013, Louisiana: Ranked eleventh among the 50 states in TB rates (3 for each 100,000 people) and 22.3% of TB cases were foreign-born people (CDC, 2015). As in the U.S., frequency has diminished
In 2014, 72% of TB cases were found among people born outside the UK. India, Pakistan and Somalia were the most frequent countries of birth for non-UK born cases, though rates among this group have decreased significantly over the last two years. This decrease in rates is also true in the non-UK born population as a whole. TB remains an illness that is associated with health inequality. People in deprived communities have rates of TB seven times higher than people in the least deprived areas. 34% of cases were found among people not in education or
Among many misconceptions, tuberculosis is not a disease of the past. Tuberculosis remains a public health issue. It is estimated that one-third of the total world population is infected by tuberculosis (TB). The American lung association (2013) states, in 2011 alone there were nearly 9,000,000 new diagnosed cases of tuberculosis around the world and an estimated 1.4 million deaths because of this disease. In the United States, TB is not as common (but still a problem). In 2011, only 10,500 people reported having TB (Trends in Tuberculosis Morbidity and
The purpose of this paper is to discuss tuberculosis (TB), provide a clinical description, and discuss the determinants of health in relation to TB and the role and tasks of the community health nurse in regards to the disease.
As the time progresses, the world population increasing exponentially which results in a higher spread of diseases. Even though it might seem like increasing population has nothing to do with Tuberculosis and it's reemergence in the 21st century, however, there are links that do provide some clue on a possible threat to the global health.
“Despite all the ghastliness in the world, human beings are made for goodness, the ones that held in high regard are not militarily powerful nor economically prosperous. They have a commitment to try and make the world a better place” (Desmond Tutu,15)- Archbishop Desmond Tutu. Strong words of hope and faith in humanity come from a man who is regarded in the same heights as Ghandi. Archbishop Desmond Tutu is a survivor of the deadly disease known as, Tuberculosis. According to the CDC, “One third of the world’s population is infected with TB” . A staggering number, but the amount of deaths from TB is even more astonishing, “1.8 million deaths in 2015” (Center for Disease Control). Most people get confused with what exactly tuberculosis even is, whether people say it’s like the flu or bronchitis, but it’s something truly life threatening. Tuberculosis is not exclusive to only one race, ethnicity, or gender, tuberculosis is able to kill anyone regardless of age. Therefore, it is important to raise awareness and educate all the people in the world of the Tuberculosis.
Tuberculosis is an infectious bacterial disease caused by the pathogen, Mycobacterium tuberculosis, and most often found in the lungs. It is transmitted via droplets from the throat and lungs of those with active respiratory disease. People with weakened immune systems can make the bacteria active which causes death of tissue in the organs infected. Symptoms usually consists of overall sensation of feeling unwell, cough, possibly with bloody mucus, fatigue, shortness of breath, weight loss, low-grade fever, night sweats, and chest pain when breathing. To stop further transmission of tuberculosis, finding patients and giving appropriate treatment as well as rapid detection of pathogen and drug resistance is effective. Typing of M. tuberculosis

Results: This study was done on 85 smear-positive pulmonary tuberculosis patients with a mean age of 65.6 (16.7) . There were 38 male patients (44.7%), 47 urban residents (55.3%), and only 6 patients (7.1%) were Afghani. Mean time of sputum conversion after starting treatment was 1.99 (1.06) months. Mean time of sputum conversion was significantly higher in males (P=0.046), increased bacilli density in the primary sputum sample (P<0.0001, R=0.507) and pre-existing medical illness (P=0.001) .No deficient relationship was found between
The risk factors for contracting the disease vary according to age, health conditions, or location. The elderly people and infants are likely to get TB mainly because their immune systems are weak. As an individual grows old, the immune system weakens and this can increase chances of being
In 2011, WHO estimated 12 million prevalent cases of tuberculosis worldwide, of which about 630 000 (roughly 5%) were MDR tuberculosis. The highest caseloads of MDR tuberculosis were reported in India, China, Russia, and South Africa, which accounted for more than 60% of cases worldwide. India and China have the highest number of MDR tuberculosis cases worldwide. Tuberculosis has now been made a notifiable disease in India. Drug resistance surveys in several states have indicated that the prevalence of MDR TB in India is 2–3 percent among new cases and 12-17 percent among reinfection cases. According to drug
So, when the infection compromised with an HIV/AIDES host, quiet the indications, the entanglements create in different ranges of human system. (Maurer and Smith 2009). It is conceivable to have the illness in different organs however just a medical practitioner could attest and to confirm that kind of disease (CDC 2013). The episodes of TB are on the decrease in the country. According to Maurer and Smith 2009. It is not yet decreasing among the minorities who were born in a different country before becoming citizens of the USA. The Healthy people recommended the predominance to be of 1% of every 100.000, however the TB rate is higher than 3% of every 100,000. (CDC 2014). The predominate mortality of the illness is quickly cared for the presence of one or more additional diseases or disorders co-occurring when it is diagnosed early and care is taken. Thus, it does not spread to the other areas of the human organs or the human system. The above occurrences that is the presence of one or more additional diseases or disorders co-occurring shows why most of the minorities in the USA are mostly affected by the illness.
