Diagnosing active tuberculosis based only on signs and symptoms is difficult, [99] as is diagnosing the disease in those who have a weakened immune system. [100] A diagnosis of TB should, however, be considered in those with signs of lung disease or constitutional symptoms lasting longer than two weeks. [ 100 ]
Mycobacterium africanum is a species of Mycobacterium that is most commonly found in West African countries, where it is estimated to cause up to 40% of pulmonary tuberculosis. [2] The symptoms of infection resemble those of M. tuberculosis. It is a member of the Mycobacterium tuberculosis complex. [3]
Symptoms of M. tuberculosis include coughing that lasts for more than three weeks, hemoptysis, chest pain when breathing or coughing, weight loss, fatigue, fever, night sweats, chills, and loss of appetite. M. tuberculosis also has the potential of spreading to other parts of the body. This can cause blood in urine if the kidneys are affected ...
Because MDR tuberculosis is an airborne pathogen, persons with active, pulmonary tuberculosis caused by a multidrug-resistant strain can transmit the disease if they are alive and coughing. [41] TB strains are often less fit and less transmissible, and outbreaks occur more readily in people with weakened immune systems (e.g., patients with HIV).
Management of tuberculosis refers to techniques and procedures utilized for treating tuberculosis (TB), or simply a treatment plan for TB.. The medical standard for active TB is a short course treatment involving a combination of isoniazid, rifampicin (also known as Rifampin), pyrazinamide, and ethambutol for the first two months.
Tuberculosis is back to being the leading infectious disease killer across the globe, surpassing COVID-19, according to a recent report from the World Health Organization.
A definitive diagnosis of tuberculosis can only be made by culturing Mycobacterium tuberculosis organisms from a specimen taken from the patient (most often sputum, but may also include pus, CSF, biopsied tissue, etc.). [1] A diagnosis made other than by culture may only be classified as "probable" or "presumed".
For example, hosts of Mycobacterium tuberculosis bacteria will only develop active tuberculosis in approximately one-tenth of cases; [6] the majority of those infected by Mtb bacteria have latent tuberculosis, a non-infectious type of tuberculosis that does not produce symptoms in individuals with sufficient immune responses.
