Mycobacterium Avium Complex (MAC) is a family of opportunistic bacterial pathogens related to mycobacterium tuberculosis that are found almost everywhere in our environment, including food, water and soil. Incidence; Risk Factors


The prevalence of MAC disease was 1.1 per 100,000 in the pre-AIDS era and these cases were most often recognized in persons with underlying lung disease.

Some types of MAC bacteria cause disease, primarily in individuals with compromised immune systems but also rarely in individuals without identified susceptibilities.

Potentially, water is a route of exposure to MAC through ingestion and inhalation of aerosols. However, given a lifetime of exposure to a ubiquitous agent and the limited number of individuals with recognized disease, the lifetime risk from MAC for the normal immunocompetent host is negligible.





Conditions that suggest Mycobacterium Avium Complex (MAC) Disease:
Skin-Hair-Nails  Night Sweats
 Micobacterium avium infection can cause night sweats. A micobacterium avium complex (MAC) diagnostic test can be done to identify the infection or rule it out. MAC is common in women with HIV/AIDS and can be deadly if left untreated.

GLOSSARY

AIDS
Acquired Immune Deficiency Syndrome. An immune system deficiency disorder that suddenly alters the body's ability to defend itself. The AIDS virus invades the T4 helper/inducer lymphocytes and multiplies, causing a breakdown in the body's immune system, eventually leading to overwhelming infection and/or cancer, with ultimate death.

Bacteria (Bacterial, Bacterium)
Microscopic germs. Some bacteria are "harmful" and can cause disease, while other "friendly" bacteria protect the body from harmful invading organisms.

Human Immunodeficiency Virus (HIV)
A retrovirus associated with onset of advanced immunodeficiency syndrome (AIDS).

Lung (Lungs, Pulmonary)
Organ of the body, located in the chest cavity which is designed to bring oxygen from the air into the blood stream, while also expelling carbon dioxide and other waste gases out of the body. Pulmonary: Related to the lungs.

Tuberculosis
Also known as TB, Consumption or "The White Plague", tuberculosis is an infectious disease caused by a bacterium called Mycobacterium tuberculosis, usually affecting the lungs but possibly also the brain, kidneys and bones. Patients may at first be symptom-free or experience a flu-like illness. In the secondary stage, there might be a slight fever, night sweats, weight loss, fatigue and various other symptoms, depending on the part of the body affected. Tuberculosis of the lung is usually associated with a dry cough that eventually leads to a productive cough with blood-stained sputum. There might also be chest pain and shortness of breath.
