Weakly gram-positive, strongly acid-fast, aerobic bacilli (rod). Lipid-rich cell wall, making the organism resistant to disinfectants, detergents, common antimicrobial drugs and traditional stains.
Capable of intracellular growth in inactivated alveolar macrophages.
Disease primarily from host response to infection.
Arranged in colonies
What else can I help you with?
Where does Mycobacterium tuberculosis hide?
Mycobacterium tuberculosis does not hide; it simply has a coating that makes it hard to detect. This waxy coating on its cell surface makes the cell impervious to gram staining.
Does mycobacterium tuberculosis produce an exotoxin?
No, Mycobacterium tuberculosis does not produce exotoxins. It mainly causes disease through its cell wall components and induces an inflammatory response in the host.
Is mycobacterium an eubacteria?
Yes, mycobacterium is a genus of eubacteria. Eubacteria are a major group of bacteria that are characterized by their simple cell structure and lack of membrane-bound organelles. Mycobacterium species include pathogenic bacteria that can cause diseases such as tuberculosis and leprosy.
Is Pyrazinamide bactericidal or bacteriostatic?
Pyrazinamide is considered bactericidal against Mycobacterium tuberculosis. It works by disrupting the mycolic acid synthesis in the cell wall, leading to cell death.
Which organism has the most complex cell wall?
Mycobacterium tuberculosis, the bacterium that causes tuberculosis, has a complex cell wall that includes unique lipids and high levels of mycolic acids, making it one of the most complex cell walls among bacteria.
Which specific Mycobacterium organism was Ehrlich trying to stain when he developed the acid-fast stain?
Ehrlich was trying to stain Mycobacterium tuberculosis, the bacterium that causes tuberculosis. The acid-fast stain he developed allows for the visualization of the unique cell wall properties of this bacterium, which resists conventional staining methods.
Is mycobacterium tuberculosis asexual or sexual?
Mycobacterium tuberculosis is primarily asexual, reproducing through binary fission. This process involves the bacterial cell dividing into two identical daughter cells, allowing for rapid population growth. While horizontal gene transfer can occur among bacteria, M. tuberculosis does not engage in sexual reproduction like some eukaryotic organisms.
What are examples of acid-fast organisms?
Examples of acid-fast organisms include Mycobacterium tuberculosis, Mycobacterium leprae, and Nocardia species. Acid-fast staining is a technique used to detect these bacteria, as they have a waxy substance in their cell walls that makes them resistant to standard staining methods.
Why is mycobacterium tuberculosis considered acid fast?
Saprophytic mycobacteria are acid fast and do not cause serious disease.
What are mycobacterium?
Mycobacterium are a type of bacteria that can cause various diseases in humans and animals, including tuberculosis and leprosy. They have a unique cell wall structure that makes them resistant to many antibiotics and disinfectants. Mycobacterium can be transmitted through respiratory droplets, contaminated food or water, or direct contact with infected individuals.
What is bycobacteria?
There is no listing for bycobacteria. Mycobacterium are groups of bacteria that are responsible for conditions such as leprosy and tuberculosis. Mycobacterium are generally considered gram positive strains of bacteria.
What do mycobacterium tuberculosis eat?
Mycobacterium tuberculosis, the bacterium that causes tuberculosis, primarily relies on the host's cellular environment for nutrients. It absorbs fatty acids, amino acids, and other organic compounds present in the host's tissues and cells. Unlike many bacteria, it has a unique cell wall structure that allows it to survive in harsh conditions and utilize a limited range of nutrients. Its metabolic processes are adapted to thrive within the macrophages of the immune system.
