What is the genus of Mycobacterium?
The genus Mycobacterium consists of a diverse group of species and subspecies ( http://www.bacterio.net/mycobacterium.html ). With the exception of Mycobacterium tuberculosis complex, Mycobacterium leprae complex, and Mycobacterium ulcerans the rest of the species are referred to as NTM, and they can be found throughout our environment. The most common clinical presentation is that of pulmonary disease, often occurring in the setting of underlying structural airway disease such as bronchiectasis or chronic obstructive pulmonary disease [ 4 ]. The incidence and prevalence of NTM pulmonary disease are increasing in many areas of the world with rates particularly high in older individuals and those with underlying bronchiectasis [ 44–48 ]. The reasons for the increases in prevalence are not fully understood but are likely multifactorial including environmental, host, and microbial factors. Regardless of the reasons for the increase, it is clear that healthcare providers will be encountering these patients increasingly frequently in the coming years.
How many species of nontuberculous mycobacteria are there?
Nontuberculous mycobacteria (NTM) represent over 190 species and subspecies, some of which can produce disease in humans of all ages and can affect both pulmonary and extrapulmonary sites. This guideline focuses on pulmonary disease in adults (without cystic fibrosis or human immunodeficiency virus infection) caused by the most common NTM pathogens ...

What are the comorbidities of M. kansasii?
kansasii pulmonary disease have underlying pulmonary comorbidities, such as smoking, chronic obstructive pulmonary disease, bronchiectasis, and prior or concurrent M. tuberculosis infection.
Is M. kansasii transmitted by humans?
Human-to-human transmission is thought not to occur. Clinical syndromes and radiological findings of M. kansasii infection are mostly indistinguishable from that of Mycobacterium tuberculosis, thus requiring microbiological confirmation.
Is M. kansasii a disseminated disease?
Disseminated disease is uncommon in HIV-negative patients and usually associated with severe immunosuppression. The majority of patients with M. kansasii pulmonary disease have underlying pulmonary comorbidities, such as smoking, chronic obstructive pulmonary disease, bronchiectasis, and prior or concurrent M. tuberculosis infection.
What are the sites of extrapulmonary disease?
Common sites of extrapulmonary disease include the lymph nodes, skin, and musculoskeletal and genitourinary systems. The specificity of gamma interferon release assays (IGRAs) for M. tuberculosis may be reduced by M. kansasii infection, as M. kansasii encodes CFP-10 and ESAT-6, two antigens targeted by IGRAs.
What is the best treatment for NTM lung infection?
Doctors treat mycobacterium avium complex (MAC) disease, the most common NTM lung infection, with a combination of three antibiotics: If you have more severe MAC disease that results from cavities in your lungs, your doctor may try rifabutin ( Mycobutin) instead of rifampin ( Rifadin, Rimactane ).
Do you need treatment for nontuberculous mycobacterial lung disease?
If you’re diagnosed with nontuberculous mycobacterial lung disease, your doctor will discuss the right treatment for you. Some people with NTM lung disease don’t need treatment. Others require ongoing treatments to keep their disease under control.
How to treat NTM lung disease?
Once you treat your NTM lung disease, you can take steps to prevent another infection. These bacteria are often found in water or moist places, so take these easy steps: Avoid hot tubs or spas. If you have a hot tub, make sure it’s outside your house.
Can a doctor check for a lung infection?
Your doctor may decide to watch and wait rather than treat your infection. They can check your symptoms and look at X-rays to make sure your lungs don’t start to show damage.

kansasii infection except localized lymphadenitis (see below) requires multidrug therapy over a long period of time. There are currently no universally accepted intermittent or short-course treatment regimens for M. kansasii disease in the United States as there are for tuberculosis.
Is M. kansasii a pulmonary disease?
Pulmonary disease is the most frequent clinical manifestation of M. kansasii infection in immun ocompetent patients. Of all NTM, M. kansasii lung disease most closely parallels the clinical course of M. tuberculosis . M. kansasii primarily affects middle aged men, but it can affect adult patients of any sex, race, or age. Until recently, symptoms and radiographic abnormalities with M. kansasii lung disease were felt to be essentially identical to those of patients with reactivation pulmonary tuberculosis. It is now apparent, and perhaps not surprising, that patients with M. kansasii lung disease can also present with non-cavitary (nodular/bronchiectatic) infiltrates similar to Mycobacterium avium complex (MAC) lung disease ( 11 ).
How much streptomycin is resistant to M. kansasii?
kansasii is less susceptible to these drugs in-vitro (but still susceptible to achievable blood/tissue levels of these drugs), all isolates will be reported resistant to INH at 0.2 mg/ml and many to 1.0 mg/ml and to streptomycin at 2.0 mg/ml.

and occurs most commonly in the southern and Central U.S. with the highest incidence of disease in the Southern states of Texas, Louisiana, and Florida and the Central states of Illinois, Kansas and Nebraska ( 27 ).
