Most infections show no symptoms, in which case it is known as latent tuberculosis. [1] Around 10% of latent infections progress to active disease that, if left untreated, kill about half of those affected. [1] Typical symptoms of active TB are chronic cough with blood-containing mucus, fever, night sweats, and weight loss. [1]
When the bacteria multiply and cause symptoms, this is called active tuberculosis disease or active TB. People with active TB can spread the infection to others.
Other parts of the medical history include prior TB exposure, infection or disease and medical conditions that increase risk for TB disease such as HIV infection. Depending on the sort of patient population surveyed, as few as 20%, or as many as 75% of pulmonary tuberculosis cases may be without symptoms. [2]
These days, the disease, which is caused by the bacterium Mycobacterium tuberculosis, is treated with specific antibiotics — sometimes for as long as nine months, the Cleveland Clinic says. TB ...
Mycobacterium tuberculosis (M. tb), also known as Koch's bacillus, is a species of pathogenic bacteria in the family Mycobacteriaceae and the causative agent of tuberculosis. [ 1 ] [ 2 ] First discovered in 1882 by Robert Koch , M. tuberculosis has an unusual, waxy coating on its cell surface primarily due to the presence of mycolic acid .
Lupus vulgaris (also known as tuberculosis luposa [1]) are painful cutaneous tuberculosis skin lesions with nodular appearance, most often on the face around the nose, eyelids, lips, cheeks, ears [2] and neck. It is the most common Mycobacterium tuberculosis skin infection. [3] The lesions may ultimately develop into disfiguring skin ulcers if ...
Miliary tuberculosis is a form of tuberculosis that is characterized by a wide dissemination into the human body and by the tiny size of the lesions (1–5 mm). Its name comes from a distinctive pattern seen on a chest radiograph of many tiny spots distributed throughout the lung fields with the appearance similar to millet seeds—thus the term "miliary" tuberculosis.
The history of tuberculosis encompasses the origins of the disease, tuberculosis (TB) through to the vaccines and treatments methods developed to contain and mitigate its impact. Throughout history, the disease tuberculosis has been variously known as consumption, phthisis, and the White Plague.
