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.Tetracyclines: Closely congeneric derivatives of the polycyclic naphthacenecarboxamide. (Gilman et al., Goodman and Gilman's The Pharmacological Basis of Therapeutics, 8th ed, p1117)Trichomonas vaginalis: A species of TRICHOMONAS that produces a refractory vaginal discharge in females, as well as bladder and urethral infections in males.Sexually Transmitted Diseases, Bacterial: Bacterial diseases transmitted or propagated by sexual conduct.Doxycycline: A synthetic tetracycline derivative with similar antimicrobial activity.Sexually Transmitted Diseases: Diseases due to or propagated by sexual contact.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)Spectinomycin: An antibiotic produced by Streptomyces spectabilis. It is active against gram-negative bacteria and used for the treatment of gonorrhea.Probenecid: The prototypical uricosuric agent. It inhibits the renal excretion of organic anions and reduces tubular reabsorption of urate. Probenecid has also been used to treat patients with renal impairment, and, because it reduces the renal tubular excretion of other drugs, has been used as an adjunct to antibacterial therapy.Urine: Liquid by-product of excretion produced in the kidneys, temporarily stored in the bladder until discharge through the URETHRA.Genital Diseases, Male: Pathological processes involving the male reproductive tract (GENITALIA, MALE).Urethral Diseases: Pathological processes involving the URETHRA.Chlamydia: A genus of the family CHLAMYDIACEAE whose species cause a variety of diseases in vertebrates including humans, mice, and swine. Chlamydia species are gram-negative and produce glycogen. The type species is CHLAMYDIA TRACHOMATIS.Uterine Cervical Erosion: Loss or destruction of the epithelial lining of the UTERINE CERVIX.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.Cefixime: A third-generation cephalosporin antibiotic that is stable to hydrolysis by beta-lactamases.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.Limulus Test: Sensitive method for detection of bacterial endotoxins and endotoxin-like substances that depends on the in vitro gelation of Limulus amebocyte lysate (LAL), prepared from the circulating blood (amebocytes) of the horseshoe crab, by the endotoxin or related compound. Used for detection of endotoxin in body fluids and parenteral pharmaceuticals.Pyuria: The presence of white blood cells (LEUKOCYTES) in the urine. It is often associated with bacterial infections of the urinary tract. Pyuria without BACTERIURIA can be caused by TUBERCULOSIS, stones, or cancer.Demeclocycline: A TETRACYCLINE analog having a 7-chloro and a 6-methyl. Because it is excreted more slowly than TETRACYCLINE, it maintains effective blood levels for longer periods of time.Arthritis, Reactive: An aseptic, inflammatory arthritis developing secondary to a primary extra-articular infection, most typically of the GASTROINTESTINAL TRACT or UROGENITAL SYSTEM. The initiating trigger pathogens are usually SHIGELLA; SALMONELLA; YERSINIA; CAMPYLOBACTER; or CHLAMYDIA TRACHOMATIS. Reactive arthritis is strongly associated with HLA-B27 ANTIGEN.Tetracycline: A naphthacene antibiotic that inhibits AMINO ACYL TRNA binding during protein synthesis.Male Urogenital Diseases: Pathological processes of the male URINARY TRACT and the reproductive system (GENITALIA, MALE).Heterosexuality: The sexual attraction or relationship between members of the opposite SEX.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.Urination: Discharge of URINE, liquid waste processed by the KIDNEY, from the body.Urination Disorders: Abnormalities in the process of URINE voiding, including bladder control, frequency of URINATION, as well as the volume and composition of URINE.Toilet Training: Conditioning to defecate and urinate in culturally acceptable places.Generalization, Response: The principle that after an organism learns to respond in a particular manner to a stimulus, that stimulus is effective in eliciting similar responses.RestaurantsReference Books, Medical: Books in the field of medicine intended primarily for consultation.Toilet Facilities: Facilities provided for human excretion, often with accompanying handwashing facilities.Food: Any substances taken in by the body that provide nourishment.Dietetics: The application of nutritional principles to regulation of the diet and feeding persons or groups of persons.Coffee: A beverage made from ground COFFEA beans (SEEDS) infused in hot water. It generally contains CAFFEINE and THEOPHYLLINE unless it is decaffeinated.Urethral Stricture: Narrowing of any part of the URETHRA. It is characterized by decreased urinary stream and often other obstructive voiding symptoms.MedlinePlus: NATIONAL LIBRARY OF MEDICINE service for health professionals and consumers. It links extensive information from the National Institutes of Health and other reviewed sources of information on specific diseases and conditions.Urologic Surgical Procedures, Male: Surgery performed on the male genitalia.Urinary Fistula: An abnormal passage in any part of the URINARY TRACT between itself or with other organs.Cystoscopes: Endoscopes for visual examination of the urinary bladder.
