are mycoplasma and mycobacterium the same?

The key difference between mycoplasma and mycobacterium is the presence of a cell wall. Mycobacterium is a genus of bacteria where all species possess a thick, protective and waxy cell wall. Mycoplasma is another unique bacterial genus in which all species do not contain a cell wall around their cell membrane.

Prokaryotes. Bacteria are amongst the simplest of organisms - they are made of single cells. ... These cells do not contain membrane bound organelles such as a nucleus and mitochondria. Bacterial cells are called prokaryotic cells .

1. PPLO - a mycoplasma resistant to antibiotics that causes a kind of pneumonia in humans. pleuropneumonialike organism. mycoplasma - any of a group of small parasitic bacteria that lack cell walls and can survive without oxygen; can cause pneumonia and urinary tract infection.

Acid-fast bacillus (AFB) is a type of bacteria that causes tuberculosis and certain other infections. Tuberculosis, commonly known as TB, is a serious bacterial infection that mainly affects the lungs. It can also affect other parts of the body, including the brain, spine, and kidneys.

Mycoplasma is spread through contact with droplets from the nose and throat of infected people especially when they cough and sneeze. Transmission is thought to require prolonged close contact with an infected person. Spread in families, schools and institutions occurs slowly.

Nontuberculous mycobacterial (NTM) lung disease is a general term for a group of disorders characterized by exposure to specific bacterial germs known as mycobacteria. These germs are found in the water and soil and are common throughout the environment as a whole. They usually do not cause illness.

We can split pathogens into two categories cellular (living) and non cellular (non-living) pathogens. Bacteria are prokaryotes, thus they are simple, single celled organisms. ... Protozoa are unicellular organisms, however unlike bacteria they are Eukaryotes.

On March 24, 1882, Dr. Robert Koch announced the discovery of Mycobacterium tuberculosis, the bacteria that causes tuberculosis (TB).

Bacterial cells and human cells: Both have ribosomes, plasma membrane, cytoplasm, 70S ribosomes and DNA. Both have vesicles and vacuoles. ... Some bacteria (eg Vibrio cholerae, the bacteria that causes cholera) and human sperm cells have flagella.

Most M. pneumoniae infections are self-limiting; however, clinicians routinely treat pneumonia caused by Mycoplasma pneumoniae with antibiotics. All mycoplasmas lack a cell wall and, therefore, all are inherently resistant to beta-lactam antibiotics (e.g., penicillin).

Rickettsia. The rickettsia are bacteria which are obligate intracellular parasites. They are considered a separate group of bacteria because they have the common feature of being spread by arthropod vectors (lice, fleas, mites and ticks).

Mycoplasma bovis is a bacterium that causes illness in cattle, including udder infections (mastitis), abortion, pneumonia, and arthritis. It affects only cattle – dairy cows and beef cattle. It does not infect humans and presents no food safety risk.

They have the following characteristics: (1) the smallest mycoplasmas are 125–250 nm in size; (2) they are highly pleomorphic because they lack a rigid cell wall and instead are bounded by a triple-layered “unit membrane” that contains a sterol (mycoplasmas require the addition of serum or cholesterol to the medium to ...

Acid-fast bacteria are gram-positive, but in addition to peptidoglycan, the outer membrane or envelope of the acid-fast cell wall of contains large amounts of glycolipids, especially mycolic acids that in the genus Mycobacterium, make up approximately 60% of the acid-fast cell wall (Figure 2.3C.

Mycobacteria contain mycolic acids and have a high GC content in their DNA. A Gram stain cannot penetrate the waxy cell wall. The hydrophobic lipids cause the Gram stain to give no staining or a variable result.

In the treatment of mycoplasmal pneumonia, antimicrobials against M pneumoniae are bacteriostatic, not bactericidal. Tetracycline and erythromycin compounds are very effective. The second-generation tetracyclines (doxycycline) and macrolides are the drugs of choice.

Antibiotics that are used to treat walking pneumonia caused by Mycoplasma pneumoniae include: Macrolide antibiotics: Macrolide drugs are the preferred treatment for children and adults. Macrolides include azithromycin (Zithromax®) and clarithromycin (Biaxin®).
