Its cause was unknown until in 1882 German physician and scientist Robert Koch discovered the bacterium that causes the disease, Mycobacterium tuberculosis. This discovery has contributed to many other important events across multiple scientific disciplines. It is what lead him to receive the Nobel Prize and is…

Africa has been a hub for many of the world’s deadliest diseases and epidemics. Diseases such as malaria, tuberculosis, and HIV/Aids are responsible for millions of deaths in Africa each and every year. A major contributing factor to this issue is the current healthcare system set in place. The lack of easy access, coupled with the high cost of medication and treatment makes it very difficult for African citizens to receive the medical help that they need. Africa’s extreme poverty and lack of…

Population growth of microorganisms. In the correct conditions (with warmth, moisture, nutrients) bacteria can multiply rapidly. The human body can provide these conditions for bacteria to multiply, for example in a cut. Each bacterium splits into two up to every 20 minutes. So, after one hour a single bacterium could have reproduced to give eight bacteria. 2.2 Explain the ways an infective agent might enter the body Contact: Some diseases spread through direct contact with infected skin,…

Introduction Clinical laboratories have relied historically on phenotypic methods (i.e. culture and biochemical tests) to identify microorganisms. This can be time consuming task especially with slow growing organisms such as Mycobacterium tuberculosis. Molecular methods are now well established in the diagnosis of infectious disease. . (Harwood 2012). For the purpose of this essay I will give a brief overview of both traditional and molecular methods that re used today. I will focus on the pros…

spread anymore and it will bust and spreading necrotic residue and bacilli throughout the surrounding tissue. Other macrophages will also begin to extravasate from peripheral blood, but they are inactive because they phagocytose the Mycobacterium tuberculosis, therefore they cannot destroy the bacteria anymore. Stage Three: At stage three, lymphocytes (specifically T cells) will begin to infiltrate and recognize TB antigens. This results in T-cell activation and then it release of cytokines…

1. Forest Grove in Saskatoon is an area that has not had much focus on their community’s personal and local health. I have been living here since September and I get the impression that people keep to themselves more than necessary since we do not have any substantial community centers or local community events to bring people together. This atmosphere may affect a person’s personal health because of the potential for people to be isolated in their own homes, not feeling welcomed by their…

Most citizens cannot afford the available care and succumb to these illnesses at a younger age as a result. This case study will put more focus on the communicable diseases included in Haiti’s top 10 causes of death, specifically, Tuberculosis and HIV/AIDS. Tuberculosis (TB) is a disease caused by a bacterium that usually affects the lungs, but can affect other parts of the body as well. TB is extremely contagious and if not caught fast enough can spread…

uncommon in the United States. According to Speiser and Bowden (2016), adrenal insufficiency secondary to congenital adrenal hyperplasia occurs in approximately 1 per 16,000 infants. Worldwide, the most common cause of adrenal insufficiency is tuberculosis (TB), with a calculated incidence of this condition caused by TB at approximately 5-6 cases per million persons per…

his own style. One preceptor would perform a tuberculosis skin only if patients ask for it for employment purposes. The other preceptor, on the other hand, orders quantiferon TB gold test on every patient at initial visit and yearly. I later found out that the vast majority of patients who go to that primary care clinic are homeless, and may not come back for PPD test skin reading. In addition, this group of people are at high risk for latent tuberculosis. In that same clinic, my preceptor…

Plants have major role in changing the life of human civilization both for health as well as quality life from ancient times. Since inception of knowledge about the usefulness, out of 258,650 species of higher plants 10% are considered to be useful for curing the diseases. (Shinwari 2010). From the human civilization different systems of treatments like Ayurveda, Unani, Naturopathy, Sidha, Homeopathy and many more have been devised ; but the source almost remain same i.e., medicinal plants for…
