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 Infections: Infections with species of the genus MYCOPLASMA.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.Sexually Transmitted Diseases, Bacterial: Bacterial diseases transmitted or propagated by sexual conduct.Urethritis: Inflammation involving the URETHRA. Similar to CYSTITIS, clinical symptoms range from vague discomfort to painful urination (DYSURIA), urethral discharge, or both.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 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.Uterine Cervicitis: Inflammation of the UTERINE CERVIX.Pelvic Inflammatory Disease: A spectrum of inflammation involving the female upper genital tract and the supporting tissues. It is usually caused by an ascending infection of organisms from the endocervix. Infection may be confined to the uterus (ENDOMETRITIS), the FALLOPIAN TUBES; (SALPINGITIS); the ovaries (OOPHORITIS), the supporting ligaments (PARAMETRITIS), or may involve several of the above uterine appendages. Such inflammation can lead to functional impairment and infertility.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.Ureaplasma Infections: Infections with bacteria of the genus UREAPLASMA.Ureaplasma: A genus of gram-negative, nonmotile bacteria which are common parasitic inhabitants of the urogenital tracts of humans, cattle, dogs, and monkeys.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.Trichomonas Infections: Infections in birds and mammals produced by various species of Trichomonas.Urethra: A tube that transports URINE from the URINARY BLADDER to the outside of the body in both the sexes. It also has a reproductive function in the male by providing a passage for SPERM.DNA, Bacterial: Deoxyribonucleic acid that makes up the genetic material of bacteria.Chlamydia trachomatis: Type species of CHLAMYDIA causing a variety of ocular and urogenital diseases.Trichomonas vaginalis: A species of TRICHOMONAS that produces a refractory vaginal discharge in females, as well as bladder and urethral infections in males.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.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.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.Cervix Uteri: The neck portion of the UTERUS between the lower isthmus and the VAGINA forming the cervical canal.Azithromycin: A semi-synthetic macrolide antibiotic structurally related to ERYTHROMYCIN. It has been used in the treatment of Mycobacterium avium intracellulare infections, toxoplasmosis, and cryptosporidiosis.Mycoplasma bovis: A species of gram-negative bacteria causing MASTITIS; ARTHRITIS; and RESPIRATORY TRACT DISEASES in CATTLE.Genome, Bacterial: The genetic complement of a BACTERIA as represented in its DNA.Chlamydia Infections: Infections with bacteria of the genus CHLAMYDIA.Mycoplasma pulmonis: A species of gram-negative bacteria highly pathogenic to RATS and MICE. It is the primary cause of murine respiratory mycoplasmosis.Parametritis: Inflammation of the parametrium, the connective tissue of the pelvic floor, extending from the subserous coat of the uterus laterally between the layers of the BROAD LIGAMENT.Urine: Liquid by-product of excretion produced in the kidneys, temporarily stored in the bladder until discharge through the URETHRA.Mycoplasma gallisepticum: A species of gram-negative bacteria causing chronic respiratory disease in POULTRY.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.Sexually Transmitted Diseases: Diseases due to or propagated by sexual contact.Mycoplasma agalactiae: A species of gram-negative bacteria causing contagious agalactia of SHEEP and GOATS.Vagina: The genital canal in the female, extending from the UTERUS to the VULVA.

It causes disease in a wide variety of organs and tissues including JOINTS, tendon sheaths and the RESPIRATORY TRACT.Bacterial Adhesion: Physicochemical property of fimbriated (FIMBRIAE, BACTERIAL) and non-fimbriated bacteria of attaching to cells, tissue, and nonbiological surfaces. It is a factor in bacterial colonization and pathogenicity.Mycoplasma hyorhinis: A species of gram-negative bacteria and a common inhabitant of the NASAL CAVITY of both healthy and diseased PIGS. It is a common secondary invader in MYCOPLASMAL PNEUMONIA OF SWINE.Genes, Bacterial: The functional hereditary units of BACTERIA.Gravidity: The number of pregnancies, complete or incomplete, experienced by a female. It is different from PARITY, which is the number of offspring borne. (From Stedman, 26th ed)Gonorrhea: Acute infectious disease characterized by primary invasion of the urogenital tract.
