Microscopic organisms that lack a rigid cell wall; some species cause infections in humans.
A type of microorganism, similar to a bacterium, associated with diseases such as pneumonia and urethritis.
Group of very small organisms, the smallest free-living organisms known, some of which produce disease in humans (e.g.. Mycoplasma pneumoniae)’, also called pleuropneumonia-like organism (PPLO).
A group of very small bacteria. Three types of Mycoplasma cause disease in humans. Mycoplasma pneumoniae is responsible for a mild type of bronchitis and pneumonia that is particularly common in adolescents and young adults. Mycoplasma hominis causes kidney disease, pelvic inflammatory disease, vaginal infections, and postpartum fever (after childbirth). Ureaplasma urealyticum infects the lower urinary tract, producing inflammation and a burning sensation upon urination. Mycoplasma infections are usually treated with antibiotics.
One of a group of minute nonmotile microorganisms that lack a rigid cell wall and hence display a variety of forms. They are regarded by some authorities as primitive bacteria. The group includes some species that cause severe respiratory disease in cattle, sheep, and goats; one of these. Mycoplasma pneumoniae, causes a pneumonialike disease in man. The group also includes the pleuro-pneumonialike organisms ( PPLO).
A genus of micro-organisms which differ from bacteria in that they lack a rigid cell wall. They are responsible for widespread epidemics in cattle and poultry. For a long time the only member of the genus known to cause disease in humans was Mycoplasma pneumoniae which is responsible for the form of pneumonia known as primary atypical pneumonia particularly common in children, for whom it is the single most common cause of the disease when contracted out of hospital. Another, Mycoplasma genitalium, has now been isolated and is responsible for certain cases of non-gonococcal urethritis. Mycoplasma infections respond to tetracyclines.
A group of bacteria that lack cell walls and are highly pleomorphic. There are more than 70 organisms in this group, including 12 species that infect humans. Tetracyclines or erythromycins are effective for treatment of M. pneumoniae and M. hominis infections. Other treatment choices include some cephalosporins or fluoroquinolones.
Mycoplasmas, a genus of microorganisms, possess a unit membrane but lack a rigid cell wall, making them highly pleomorphic in nature. Unlike bacteria, they are the smallest free-living microorganisms, and have both RNA and DNA, along with ribosomes. It is now understood that many plant diseases, which were previously believed to be caused by viruses, are actually the result of mycoplasmas.
Mycoplasmas are a unique type of microorganism that exists as free-living entities without a cell wall. These microorganisms are known to be responsible for certain types of pneumonia and urinary tract infections. Upon infection, they can trigger the body’s immune response to produce cold agglutinins, which are antibodies that promote the clumping of red blood cells at lower temperatures.
Mycoplasmas are a category of bacteria, the tiniest kind capable of independent existence. They are approximately the same size as viruses, but unlike viruses, they can replicate outside of living cells. Among these, Mycoplasma pneumoniae, a specific species, is responsible for causing primary atypical pneumonia.
