Mycoplasma
Mycoplasma hominis
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.
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.
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
Mycoplasma pulmonis
Mycoplasma gallisepticum
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.
Mycoplasma agalactiae
A species of gram-negative bacteria causing contagious agalactia of SHEEP and GOATS.
Mycoplasma synoviae
Mycoplasma hyorhinis
Acholeplasma
Acholeplasma laidlawii
Pleuropneumonia, Contagious
A pleuropneumonia of cattle and goats caused by species of MYCOPLASMA.
Ureaplasma
Mycoplasma capricolum
A genus in the family ENTOMOPLASMATACEAE, order Entomoplasmatales. It is pathogenic to GOATS, causing caprine pleuropneumonia (PLEUROPNEUMONIA, CONTAGIOUS).
Mycoplasma salivarium
Mycoplasma conjunctivae
A species of gram-negative bacteria causing CONJUNCTIVITIS and KERATOCONJUNCTIVITIS in SHEEP and GOATS.
Ureaplasma urealyticum
A species of gram-negative bacteria found in the human genitourinary tract (UROGENITAL SYSTEM), oropharynx, and anal canal. Serovars 1, 3, 6, and 14 have been reclassed into a separate species UREAPLASMA parvum.
Mycoplasma iowae
Tenericutes
A phylum of gram-negative bacteria consisting of cells bounded by a plasma membrane. Its organisms differ from other bacteria in that they are devoid of cell walls. This phylum was formerly the class Mollicutes. Mollicutes is now the sole class in the phylum Tenericutes.
Mycoplasma ovipneumoniae
Ureaplasma Infections
Infections with bacteria of the genus UREAPLASMA.
Mycoplasmatales
Goats
Adhesins, Bacterial
Cell-surface components or appendages of bacteria that facilitate adhesion (BACTERIAL ADHESION) to other cells or to inanimate surfaces. Most fimbriae (FIMBRIAE, BACTERIAL) of gram-negative bacteria function as adhesins, but in many cases it is a minor subunit protein at the tip of the fimbriae that is the actual adhesin. In gram-positive bacteria, a protein or polysaccharide surface layer serves as the specific adhesin. What is sometimes called polymeric adhesin (BIOFILMS) is distinct from protein adhesin.
Spiroplasma
Complement Fixation Tests
Serologic tests based on inactivation of complement by the antigen-antibody complex (stage 1). Binding of free complement can be visualized by addition of a second antigen-antibody system such as red cells and appropriate red cell antibody (hemolysin) requiring complement for its completion (stage 2). Failure of the red cells to lyse indicates that a specific antigen-antibody reaction has taken place in stage 1. If red cells lyse, free complement is present indicating no antigen-antibody reaction occurred in stage 1.
Polymerase Chain Reaction
In vitro method for producing large amounts of specific DNA or RNA fragments of defined length and sequence from small amounts of short oligonucleotide flanking sequences (primers). The essential steps include thermal denaturation of the double-stranded target molecules, annealing of the primers to their complementary sequences, and extension of the annealed primers by enzymatic synthesis with DNA polymerase. The reaction is efficient, specific, and extremely sensitive. Uses for the reaction include disease diagnosis, detection of difficult-to-isolate pathogens, mutation analysis, genetic testing, DNA sequencing, and analyzing evolutionary relationships.
Molecular Sequence Data
Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories.
Hemadsorption
Arthritis, Infectious
Urethritis
Cat Diseases
Cattle Diseases
Culture Media
Any liquid or solid preparation made specifically for the growth, storage, or transport of microorganisms or other types of cells. The variety of media that exist allow for the culturing of specific microorganisms and cell types, such as differential media, selective media, test media, and defined media. Solid media consist of liquid media that have been solidified with an agent such as AGAR or GELATIN.
Bacterial Adhesion
RNA, Bacterial
Sexually Transmitted Diseases, Bacterial
Species Specificity
The restriction of a characteristic behavior, anatomical structure or physical system, such as immune response; metabolic response, or gene or gene variant to the members of one species. It refers to that property which differentiates one species from another but it is also used for phylogenetic levels higher or lower than the species.
RNA, Ribosomal, 16S
Mycoplasma dispar
Mycoplasmatales Infections
Infections with bacteria of the order MYCOPLASMATALES.
Keratoconjunctivitis, Infectious
Infectious diseases of cattle, sheep, and goats, characterized by blepharospasm, lacrimation, conjunctivitis, and varying degrees of corneal opacity and ulceration. In cattle the causative agent is MORAXELLA (MORAXELLA) BOVIS; in sheep, MYCOPLASMA; RICKETTSIA; CHLAMYDIA; or ACHOLEPLASMA; in goats, RICKETTSIA.
Sequence Analysis, DNA
Mycoplasma hyosynoviae
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.

Antigenic Variation
Change in the surface ANTIGEN of a microorganism. There are two different types. One is a phenomenon, especially associated with INFLUENZA VIRUSES, where they undergo spontaneous variation both as slow antigenic drift and sudden emergence of new strains (antigenic shift). The second type is when certain PARASITES, especially trypanosomes, PLASMODIUM, and BORRELIA, survive the immune response of the host by changing the surface coat (antigen switching).
