Although TB rates are decreasing in the United States, the disease is becoming more common in many parts of the world. In addition, the prevalence of drug-resistant TB is increasing worldwide. TB is caused by M tuberculosis, a slow-growing obligate aerobe and a facultative intracellular parasite. The organism grows in parallel groups called cords (as seen in the image below). It retains many …show more content…

(McMurray, 2007). “The agent in this study is Mycobacterium tuberculosis, an acid fast aerobic rod that reproduces slowly and is hypersensitive to heat and ultraviolet light. TB primarily affects the respiratory system; however, it can also affect the pericardium, lymph nodes, meninges, kidneys, intestines, bones, joints, and reproductive organs” (The Merck Manual, 2014). “The transmission of the Mycobacterium tuberculosis is spread from person to person via airborne droplets through actions such as coughing, talking and sneezing. The smaller the droplet, the longer it can stay in the air after the infected person has left the area. This causes an increase in the probability of inhalation by another individual. Passing TB from a family member or co-worker is more likely than a stranger in a store or on the streets”. (Reichler et. al, 2002). Mycobacterium tuberculosis, the infectious disease agent, is readily transmitted to susceptible humans, the host, through respiratory exposure in communal settings or public gatherings, the environment. Individuals with compromised immune systems, such as cancer, being on corticosteroid therapy, and HIV/AIDS, are at greatest risk for getting TB infection. Healthcare workers are continuously exposed to illnesses at the hospitals and long term care facilities, which puts them at risk for
