Pneumonia, Mycoplasma: Interstitial pneumonia caused by extensive infection of the lungs (LUNG) and BRONCHI, particularly the lower lobes of the lungs, by MYCOPLASMA PNEUMONIAE in humans. In SHEEP, it is caused by MYCOPLASMA OVIPNEUMONIAE. In CATTLE, it may be caused by MYCOPLASMA DISPAR.Mycoplasma pneumoniae: Short filamentous organism of the genus Mycoplasma, which binds firmly to the cells of the respiratory epithelium. It is one of the etiologic agents of non-viral primary atypical pneumonia in man.Mycoplasma: A genus of gram-negative, mostly facultatively anaerobic bacteria in the family MYCOPLASMATACEAE. The cells are bounded by a PLASMA MEMBRANE and lack a true CELL WALL. Its organisms are pathogens found on the MUCOUS MEMBRANES of humans, ANIMALS, and BIRDS.Mycoplasma Infections: Infections with species of the genus MYCOPLASMA.Pneumonia, Bacterial: Inflammation of the lung parenchyma that is caused by bacterial infections.Pneumonia: Infection of the lung often accompanied by inflammation.Klebsiella pneumoniae: Gram-negative, non-motile, capsulated, gas-producing rods found widely in nature and associated with urinary and respiratory infections in humans.Pneumonia, Pneumococcal: A febrile disease caused by STREPTOCOCCUS PNEUMONIAE.Streptococcus pneumoniae: A gram-positive organism found in the upper respiratory tract, inflammatory exudates, and various body fluids of normal and/or diseased humans and, rarely, domestic animals.Mycoplasma hominis: A common inhabitant of the vagina and cervix and a potential human pathogen, causing infections of the male and female reproductive tracts. It has also been associated with respiratory disease and pharyngitis. (From Dorland, 28th ed)Mycoplasma genitalium: A species of gram-negative bacteria originally isolated from urethral specimens of patients with non-gonoccocal URETHRITIS. In primates it exists in parasitic association with ciliated EPITHELIAL CELLS in the genital and respiratory tracts.Klebsiella Infections: Infections with bacteria of the genus KLEBSIELLA.Mycoplasma fermentans: A species of the genus MYCOPLASMA, originally isolated infrequently from the lower genital tract of humans, and possessing uncertain pathogenicity. The incognitus strain of M. fermentans has been identified in necrotizing lesions of multiple organs from AIDS and non-AIDS patients dying of an acute influenza-like disease.Mycoplasma mycoides: The etiological agent of contagious pleuropneumonia (PLEUROPNEUMONIA, CONTAGIOUS) of cattle and goats.Community-Acquired Infections: Any infection acquired in the community, that is, contrasted with those acquired in a health care facility (CROSS INFECTION). An infection would be classified as community-acquired if the patient had not recently been in a health care facility or been in contact with someone who had been recently in a health care facility.Chlamydophila pneumoniae: A species of CHLAMYDOPHILA that causes acute respiratory infection, especially atypical pneumonia, in humans, horses, and koalas.Mycoplasma hyopneumoniae: A species of gram-negative bacteria that causes MYCOPLASMA PNEUMONIA OF SWINE. The organism damages the CILIA in the airways of the pig, and thus compromises one of the most effective mechanical barriers against invading pathogens. The resulting weakening of the IMMUNE SYSTEM can encourage secondary infections, leading to porcine respiratory disease complex.Mycoplasma bovis: A species of gram-negative bacteria causing MASTITIS; ARTHRITIS; and RESPIRATORY TRACT DISEASES in CATTLE.Macrolides: A group of often glycosylated macrocyclic compounds formed by chain extension of multiple PROPIONATES cyclized into a large (typically 12, 14, or 16)-membered lactone. Macrolides belong to the POLYKETIDES class of natural products, and many members exhibit ANTIBIOTIC properties.Mycoplasma gallisepticum: A species of gram-negative bacteria causing chronic respiratory disease in POULTRY.Anti-Bacterial Agents: Substances that reduce the growth or reproduction of BACTERIA.Mycoplasma pulmonis: A species of gram-negative bacteria highly pathogenic to RATS and MICE. It is the primary cause of murine respiratory mycoplasmosis.Mycoplasma penetrans: A species of gram-negative, facultatively anaerobic bacteria. This organism shows remarkable pathobiologic properties: it adheres to cell surfaces, deeply penetrates into the cell, and strongly adsorbs human red blood cells and human CD4+ lymphocytes and monocytes. M. penetrans was first isolated from the urogenital tract of patients with AIDS and high frequencies of antibodies to it are seen in HIV-infected patients.Antibodies, Bacterial: Immunoglobulins produced in a response to BACTERIAL ANTIGENS.PubMed: A bibliographic database that includes MEDLINE as its primary subset. It is produced by the National Center for Biotechnology Information (NCBI), part of the NATIONAL LIBRARY OF MEDICINE. PubMed, which is searchable through NLM's Web site, also includes access to additional citations to selected life sciences journals not in MEDLINE, and links to other resources such as the full-text of articles at participating publishers' Web sites, NCBI's molecular biology databases, and PubMed Central.Electronic Mail: Messages between computer users via COMPUTER COMMUNICATION NETWORKS. This feature duplicates most of the features of paper mail, such as forwarding, multiple copies, and attachments of images and other file types, but with a speed advantage. The term also refers to an individual message sent in this way.Microbiology: The study of microorganisms such as fungi, bacteria, algae, archaea, and viruses.Microbiological Techniques: Techniques used in microbiology.Periodicals as Topic: A publication issued at stated, more or less regular, intervals.Journal Impact Factor: A quantitative measure of the frequency on average with which articles in a journal have been cited in a given period of time.Canada: The largest country in North America, comprising 10 provinces and three territories. Its capital is Ottawa.Blue Toe Syndrome: A condition that is caused by recurring atheroembolism in the lower extremities. It is characterized by cyanotic discoloration of the toes, usually the first, fourth, and fifth toes. Discoloration may extend to the lateral aspect of the foot. Despite the gangrene-like appearance, blue toes may respond to conservative therapy without amputation.Republic of Korea: The capital is Seoul. The country, established September 9, 1948, is located on the southern part of the Korean Peninsula. Its northern border is shared with the Democratic People's Republic of Korea.Genomics: The systematic study of the complete DNA sequences (GENOME) of organisms.
  • Several species of pathogenic mycoplasmas, for example, M hyorhinis , Mycoplasma bovis, and Mycoplasma gallisepticum, have sophisticated genetic machinery for altering their surface characteristics by mechanisms such as phase variation, size variation, and epitope masking and demasking of surface proteins.

  • Proteogenomic mapping resulted in the identification of previously unannotated genes gatC and rpmF and 5-prime extensions to genes mhp063, mhp073, and mhp451, all conserved and annotated in other M. hyopneumoniae strains and Mycoplasma species. (biomedcentral.com)
  • Mycoplasma pneumoniae-specific antibody-secreting cells (ASCs) in the peripheral blond were enumerated with an enzyme-linked immunospot assay in 12 children with mycoplasma pneumonia. (elsevier.com)
  • The serum level of M. pneumoniae antibody measured by enzyme-linked immunosorbent assay remained high in the convalescent phase, while the number of specific ASCs decreased. (elsevier.com)
  • Whereas this observation may be explained by declined degeneration or consumption of the antibody in the convalescent phase, it may be suggestive of the source of M. pneumoniae antibody other than ASCs in the peripheral blood. (elsevier.com)
  • Well, I've noticed that already in my practice, because I've been applying the variety of tests to patients based on your early work, I've been finding that the standard antibody testing which is typical IgG and IgM for mycoplasma pneumoniae, for example, is not at all a valid test compared to PCR.

  • Such a great increase in the numbers of total IgSCs in comparison with that in M. pneumoniae-specific ASCs suggests that the majority of the IgSC increase in the course of mycoplasmal infection was nonspecific to M. pneumoniae. (elsevier.com)
