Mycobacterium avium complex organisms predominantly

Medical treatment of pulmonary Mycobacterium avium complex (MAC) disease does not always provide curative effects and is frequently hampered by recurrence. This suggests the presence of a reservoir for MAC in the environment surrounding patients. We previously reported the recovery of MAC isolates from the residential bathrooms of outpatients MAC lung disease is an infection caused a group of bacteria called Mycobacterium avium complex (MAC). MAC includes two closely related species, Mycobacterium avium and Mycobacterium intracellulare, and may also be referred to as MAI Mycobacterium avium complex (MAC) currently comprises eight species of environmental and animal-associated, slowly-growing mycobacteria: Mycobacterium avium, Mycobacterium intracellulare, Mycobacterium chimaera, Mycobacterium colombiense, Mycobacterium arosiense, Mycobacterium bouchedurhonense, Mycobacterium marseillense and Mycobacterium timonense

MYCOBACTERIUM AVIUM complex (MAC) consists of nontuberculous mycobacteria that cause disease in immunocompromised and immunocompetent hosts. The organisms are ubiquitous in the environment, and acquisition occurs through ingestion or inhalation of aerosols from soil, water, or biofilms Group 1 organisms are photochromogens; colonies form pigment only after exposure to light, and include Mycobacterium kansasii and Mycobacterium marinum.35 Group 2 organisms are scotochromo-gens, capable of forming pigment in the dark, and include Mycobacterium gordonae. Organisms in the group 3 belong to the M avium-intracellulare family and. Mycobacterium avium complex (MAC) is caused by a group of organisms (over 30 serovars) including, Mycobacterium avium. The organisms may cause disease not only in birds, but other warm and cold-blooded vertebrate species. In humans it tends to be an opportunistic infection that is primarily found in immunocompromised individuals Mycobacterium avium complex (MAC) organisms, which are thought to be acquired by inhalation or ingestion, are found throughout the environment. Environmental sites harboring MAC include water, soil, animals, birds, foods, and, in one study, tobacco products

Mycobacterium avium complex is a group of mycobacteria comprising Mycobacterium intracellulare and Mycobacterium avium that are commonly grouped because they infect humans together; this group, in turn, is part of the group of nontuberculous mycobacteria The electrophoretic mobilities (EPMs) of 30 Mycobacterium avium complex organisms were measured. The EPMs of 15 clinical isolates ranged from -1.9 to -5.0 microM cm V(-1) s(-1), and the EPMs of 15 environmental isolates ranged from -1.9 to -4.6 microM cm V(-1) s(-1) at pH 7. PMCID: PMC520856 PMID: 15345456 [Indexed for MEDLINE] MeSH terms. Pulmonary Mycobacterium avium complex (MAC) infection is a type of non-tuberculous mycobacterial (NTM) infection. It is relatively common and continues to pose significant therapeutic challenges. In addition, the role of MAC in pulmonary pathology remains controversial in many instances Mycobacterium avium Complex (MAC) Mycobacterium avium complex (MAC) includes the organisms Mycobacterium avium and Mycobacterium intracellulare and are ubiquitous in the environment

Mycobacterium avium complex (MAC) contains 28 serovars of two species of mycobacteria: Mycobacterium avium and Mycobacterium intracellulare. These species are rod-shaped and non-motile. They are slow-growing species that cause opportunistic infections to animals, and immunosuppressed humans. MAC is prevalent in the environment Mycobacterium avium and Mycobacterium intracellulare, known collectively as Mycobacterium avium-intracellulare or Mycobacterium avium complex (MAC), are acid-fast bacilli that have been recognized primarily for their role in cases of atypical tuberculosis. These organisms are now recognized as causative agents of diarrheal symptoms as well Mycobacterium avium complex organisms. Mycobacterium avium complex is a group of mycobacteria comprising Mycobacterium intracellulare and Mycobacterium avium that are commonly grouped because they infect humans together; this group, in turn, is part of the group of nontuberculous mycobacteria Genotyping of Mycobacterium avium complex organisms using multispacer sequence typing Mycobacterium avium complex (MAC), also called Mycobacterium avium-intracellulare complex, is a microbial complex of three Mycobacterium species (i.e. M. avium, M. intracellulare, and M. chimaera. It causes Mycobacterium avium-intracellulare infection. Some sources also include Mycobacterium avium subspecies paratuberculosis (MAP)

Mycobacterium avium complex, or MAC, includes three species; Mycobacterium avium, Mycobacterium Chimaera, and Mycobacterium intracellulare. MAC is the most common nontuberculous mycobacteria, or NTM. The three different species of MAC are difficult to differentiate and cause the same spectrum of diseases, so they are often grouped together Growth temperature profiles for MAC organisms indicate that most M. avium strains may survive in hot water plumbing systems whereas the majority of M. intracellulare and MX strains may not survive temperatures greater than 49 degrees C. The optimum growth temperature of MX differed significantly from M. avium but not from M. intracellulare

A: Mycobacterium avium intracellulare (MAI) or Mycobacterium avium Complex (MAC) is an atypical NON-TB germ (micro-organism). MAC is related to the tuberculosis germ, but is not contagious and the MAC microbes live in the environment. It comprises more than one type of microorganism (both M. avium and M. intracellulare). It causes. Organisms of the Mycobacterium avium complex cause disseminated blood-borne infection in patients with AIDS, who acquire the infection mainly through the gastrointestinal tract. Prior to causing infection, M. avium must colonize and invade the intestinal mucosa. This study examined the ability of several serovars of the M. avium complex to bind.

An infection caused by a group of bacteria called Mycobacterium avium complex (MAC). MAC includes Mycobacterium avium, Mycobacterium intracellulare, and other similar mycobacteria species.MAC bacteria can be found in drinking water, dirt, and household dust. MAC infection usually starts in the lungs and intestines, but can spread throughout the body (disseminated) Mycobacterium avium complex (MAC) refers to infections caused by one of two nontuberculous mycobacterial species, either M. avium or M. intracellulare. Infection with these organisms can occur in patients with or without HIV infection. The two principal forms of MAC infection in patients with HIV are disseminated disease and focal lymphadenitis Mycobacterium avium complex (MAC) bacteria are the most frequent causative agents of non-tuberculous mycobacterial pulmonary disease. MAC pulmonary disease has two main manifestations: a fibrocavitary disease, which is diagnosed in patients with underlying lung pathology such as chronic obstructive pulmonary disease; and a nodular/bronchiectatic disease, which is diagnosed in elderly patients. Members of the Mycobacterium avium complex (MAC) are important environmental pathogens that are implicated in several chronic, idiopathic diseases. Diagnosis of MAC-based diseases is compromised by the need to cultivate these fastidious and slowly growing organisms in order to identify which mycobacterial species are present

A particularly pathogenic group of mycobacteria belong to the Mycobacterium avium complex (MAC), which includes M. avium and M. intracellulare. MAC organisms cause disease in children, the elderly, and immuno-compromised individuals. A critical step in preventing MAC infections is identifying the source of infection and preventing exposure to that source Mycobacterium avium complex is a nonmotile, non-spore-forming, gram-positive acid-fast bacillus. Mycobacterium avium complex is a nonchromogen and slow growing and takes about 10 to 20 days to develop mature colonies 8). Mycobacterium avium complex belongs to class III of the Runyon classification MYCOBACTERIUM AVIUM COMPLEX PULMONARY DISEASE (MAC/MAI) and/or BRONCHIECTASIS. I found only 1 thread on mycobacterium accidently under the catagory Lungs. I'm hoping by starting a subject matter directly related to MYCOBACTERIUM AVIUM COMPLEX PULMONARY DISEASE (MAC/MAI) I may find others out there! I was diagnosed by a sputum culture. Mycobacterium avium complex (MAC) is widely distributed in the environment, and exposure to the organisms is common. However, while many persons are transiently colonized with MAC, disease due to MAC is rare. Persons with AIDS are particularly susceptible to MAC disease, and in such persons the organisms disseminate widely


Mycobacterium tuberculosis is a bacterium that causes tuberculosis (TB) in humans. When inhaled, the bacterium can settle in the lungs, where it begins to grow. If not treated, it can spread to. The incidence of nontuberculous mycobacterial (NTM) pulmonary disease caused by Mycobacterium avium complex (MAC) in apparently immune-competent people is increasing worldwide. We performed a systematic review of the published literature on five-year all-cause mortality in patients with MAC lung disease, and pooled the mortality rates to give an overall estimate of five-year mortality from. Figure 2. Hypothesis for the causes of the steep global increase in pulmonary Mycobacterium avium complex (MAC) diseases. MAC organisms are ubiquitous in the environment. Many studies have indicated that these organisms tend to occur in the household Mycobacterium Avium Complex (MAC) refers to species M. avium and M. intracellulare; Clinical Features. MAC primarily affects immunocompromised patients; Most commonly affects lungs Productive cough, fever, dyspnea, fatigue, night sweats; May present as: disseminated infection, lymphadenitis, abscess (cutaneous or brain) Antibiotic Sensitivitie Activity of subinhibitory concentrations of dapsone alone and in combination with cell-wall inhibitors against Mycobacterium avium complex organisms.
