| Description | Mycobacterium avium is a mesophilic microbe, preferring temperatures between 25-40°C, and is a heterotroph, deriving its energy from organic molecules. It employs aerobic respiration as its primary method of energy production, utilizing oxygen to break down its carbon-based energy sources. As a Gram-positive bacterium, M. avium's cell wall is composed of a thick peptidoglycan layer, which gives it a distinctive staining characteristic. Its shape is typically coccobacillary, with smooth, non-motile, and non-spore-forming cells. M. avium can be found in various body sites, including the respiratory tract, skin, and gastrointestinal tract, across all mammalian species. Its presence is often asymptomatic, but it can also cause opportunistic infections in individuals with compromised immune systems. The microbe is an obligate aerobe, requiring a constant supply of oxygen to survive. It thrives in environments with moderate to high levels of oxygen, such as the human lung and intestinal tract. One notable characteristic of M. avium is its ability to form biofilms, complex communities of microorganisms attached to surfaces. This allows it to adapt to its environment and resist host immune responses. In addition to its biological characteristics, M. avium has gained significant attention in recent years due to its potential role in the development of disease. The microbe's ability to form biofilms and evade host immune responses makes it a challenging target for treatment, and its presence has been implicated in various respiratory and gastrointestinal disorders. Furthermore, the increasing prevalence of antibiotic-resistant strains has led to increased research into the development of novel therapeutic strategies against M. avium. |
