canine prostatic secretions kill trichomonas vaginalis.the zinc content of prostatic secretions is thought to be an important nonspecific defense against urinary tract infection in men. this investigation measured killing by prostatic fluid of trichomonas vaginalis, a common sexually transmitted pathogen, and related this activity to zinc concentration. we used a canine model which closely resembles the human male genital tract. prostatic secretions from all dogs killed all t. vaginalis isolates. there appear to be several mechanisms for killing of ...19826980837
zinc sensitivity of trichomonas vaginalis: in vitro studies and clinical implications.the high zinc concentration (2.3-15.3 mm) in human prostatic secretions may be an important defense of the male lower urinary tract against infection by trichomonas vaginalis. trichomonads were rapidly killed by zinc salts at concentrations similar to those in prostatic fluid of normal men. there was some variation in the zinc sensitivity of 15 clinical isolates of t. vaginalis (minimal inhibitory concentration, 0.8-6.4 mm). a time-kill technique showed subtle differences in the kinetics of zinc ...19826980958
[trichomonal infections in promiscuous women].vaginal swabs taken from 2,096 promiscuous women were examined microscopically and more swabs from 1,813 women were cultivated. the women examined were divided into 4 different age groups (15-20 years, 21-25 years, 26-30 years and over 30 years). the occurrence of trichomonadosis was diminishing with the age: 65.0%--51.2%--47.7%--41.8%. the occurrence of gonorrhoea was bit lower among the youngest women (25.9%) than among the older ones, the lowest occurrence being among the group of over 30 yea ...19826982010
evaluation of an enzyme-linked immunosorbent assay for the detection of antibody to trichomonas vaginalis in sera and vaginal secretions.using a whole-cell antigen antibody to trichomonas vaginalis was measured by an enzyme-linked immunosorbent assay (elisa). igg antibody was found in sera from only three of 99 children under 12 years of age. in contrast, serum igg or igm antibody or both were detected in 80.4% of women who had vaginal trichomoniasis and in 13.7% of uninfected women. although antibody was found in cervical and vaginal secretions, the correlation between current infection and the presence of antibody was poorer th ...19826982095
antibody to trichomonas vaginalis in human cervicovaginal secretions.human cervicovaginal secretions were obtained from patients at the gynecology and obstetrics clinics at national taiwan university hospital and cathay general hospital, republic of china. among the 500 patients examined, 33 (6.6%) were infected with trichomonas vaginalis as determined by the culture method. secretions from 24 of the infected patients and 30 noninfected women were assayed for anti-t. vaginalis immunoglobulins by the indirect immunofluorescent antibody technique. a few serum sampl ...19826982231

induction of lung tumors and lymphomas in balb/c mice by metronidazole.metronidazole, which is widely used in the treatment of "trichomonas vaginalis", "entamoeba histolytica" and "giardia lamblia" infections, was administered to balb/c mice by stomach tube in an aqueous solution at a dose rate of 2 mg/day for 100 days (total 200 mg) to test its carcinogenicity. the treatment induced a significant increase in lung tumors in male mice (p less than 0.001) and provoked the appearance of lymphomas in females (p less than 0.001). although there is insufficient evidence ...19836649066
[statistical evaluation and diagnostic consideration on trichomoniasis and candidiasis in vaginal pathology].from 1980 to 1982, we studied 1,827 cases of vaginal smears with particular interest in positive cases of trichomonas vaginalis and candida sp. moreover, we studied the statistical incidence of these microorganisms, and also some diagnostic problems, and the effects of these agents on vaginal microflora.19836675046
vaginal infections. how to identify and treat them.vaginal infection occurs at some time in the majority of women. most such infections are caused by candida albicans, trichomonas vaginalis, and gardnerella (hemophilus) vaginalis. some less common--but in many cases increasingly prevalent--causes include herpes-virus type 2, papillomavirus, chlamydia trachomatis, mycoplasma t strains, and toxic shock syndrome.19836681672
urine as a specimen for diagnosis of sexually transmitted diseases.the case of specimen collection has led to the suggestion that urine might be a useful specimen for the isolation of sexually transmitted disease agents. it would only be an appropriate specimen for agents that infect the urethra, such as neisseria gonorrhoeae or chlamydia trachomatis. comparative tests have shown that culture of urine for chlamydiae (from men with urethritis) or for gonococci from women is an insensitive procedure. gonococci can be isolated from urine from men at rates essentia ...19836309002
human milk kills parasitic intestinal protozoa.giardia lamblia, a common pathogenic intestinal parasite of humans, was rapidly killed by exposure to normal human milk in vitro. the killing did not depend on secretory immunoglobulin a. entamoeba histolytica, the dysentery amoeba, was also killed by normal human milk. giardia-cidal activity cochromatographed with an unusual lipase that is present in the milk of humans but not of lower mammals. human milk may play a protective role in infants exposed to this parasite.19836310751
the pathway of arginine catabolism in the parasitic flagellate trichomonas vaginalis.arginine is rapidly depleted from the medium during the cultivation of t. vaginalis in a defined or semi-defined medium. it is broken down to ornithine, ammonia and carbon dioxide by the three enzymes of the dihydrolase pathway: arginine deiminase, catabolic ornithine carbamyltransferase (octase) and carbamate kinase. arginase and urease as well as citrulline hydrolase appear to be absent. ornithine, a product of the pathway was further converted to putrescine by an active ornithine decarboxylas ...19836312311

antigen analysis of several pathogenic strains of trichomonas vaginalis.analysis of several human strains of trichomonas vaginalis and one bovine strain of tritrichomonas foetus was accomplished with standard sodium dodecyl sulfate-gel electrophoresis and fluorography technology. highly motile, live trichomonads were radiolabeled, and total trichloroacetic acid-precipitated proteins were electrophoresed. complex protein profiles of the various human strains of t. vaginalis were obtained with proteins ranging in molecular weight from 20,000 to greater than 200,000. t ...19836601618
acquisition of alpha 1-antitrypsin by a pathogenic strain of trichomonas vaginalis.the interaction of alpha 1-antitrypsin, the major serine protease inhibitor in plasma, with pathogenic trichomonas vaginalis and the acquisition by trichomonads of this host protein from normal human plasma were investigated. alpha 1-antitrypsin acquired by intact parasites could not be removed by repeated washings in phosphate-buffered saline. saturation kinetics were observed after incubation of glutaraldehyde-fixed organisms with 125i-labeled alpha 1-antitrypsin. evidence suggesting that spec ...19836601623

isolation of trichomonas vaginalis from the respiratory tract of infants with respiratory disease.trichomonas vaginalis was isolated from the respiratory tracts of two infants with respiratory disease. bacterial and viral cultures of tracheal aspirates and nasopharyngeal specimens did not detect bacterial pathogens or viruses; however, t vaginalis was found to be present in inoculated cell cultures. both infants were delivered vaginally by mothers with known previous episodes of t vaginalis infection. the possibility that this organism may, on occasion, cause respiratory tract disease needs ...19836602324
analysis of surface saccharides in trichomonas vaginalis strains with various pathogenicity levels by fluorescein-conjugated plant lectins.certain surface saccharides of organisms from clone-derived cultures of five trichomonas vaginalis strains, jh30a-cl. 1, jh31a-cl. 1, jh32a-cl. 1, jh34a-cl. 1, jh162a-cl. 1, and jh384a-cl. 2, which differed in their pathogenicity for women and experimental hosts, were compared with the aid of fluorescein-conjugated plant lectins using a quantitative fluorescence method. the lectins used were: concanavalin a (con-a), wheat germ agglutinin (wga), soybean agglutinin (sba), castor bean agglutinin (c ...19836602431

immune response to trichomonas vaginalis. iv. immunochemical and immunobiological analyses of t. vaginalis antigen.the immune response of patients with trichomoniasis vaginitis to trichomonas vaginalis was examined by using passive hemagglutination assay and skin reactions. trichomonas-specific immune responses could hardly be detected in the patients by these assay methods. in order to develop a simple and reliable assay for demonstration of t. vaginalis-specific immune responses in the patients, proliferation responses of peripheral mononuclear cells from the patients were examined. lymphocytes obtained fr ...19836603425
the antagonistic effects of acetate and lactate upon the trichomonacidal activity of metronidazole.lactate and acetate at 5 mm were found to be antagonistic to the killing action of metronidazole on trichomonas vaginalis under aerobic but not anaerobic conditions. these compounds had no effect on the growth of the parasite, or the rate of metronidazole reduction by, and the activities of nadh oxidase and nadph oxidase in, parasite homogenates. the phenomenon reported could be one reason why metronidazole is not always effective in the treatment of trichomoniasis.19836603456
natural macrophage cytotoxicity against trichomonas vaginalis is mediated by soluble lytic factors.mechanisms of lysis of the extracellular protozoan trichomonas vaginalis by uninduced resident macrophages were analyzed. supernatants obtained by culturing such macrophages with t. vaginalis were cytotoxic for the protozoa in a dose-dependent manner. supernatants from macrophages cultured alone were cytotoxic at lower levels, whereas those obtained from t. vaginalis alone and from macrophages cultured with unrelated cells (b77) were not cytotoxic. cytotoxic activity appeared after 4 h of contac ...19836604025
beta-hemolytic activity of trichomonas vaginalis correlates with virulence.the reasons that some women develop symptomatic trichomonal vaginitis, whereas many other infected women remain asymptomatic, are unclear, but it has been suggested that trichomonas vaginalis strains vary in their intrinsic virulence. we describe beta-hemolytic activity in t. vaginalis which correlates with virulence in patients as well as in an animal model and in tissue culture. fresh t. vaginalis isolates from four women with severe, symptomatic trichomoniasis had high-level (86.3 +/- 6.6%) h ...19836604026
amine content of vaginal fluid from patients with trichomoniasis and gardnerella associated non-specific vaginitis.amounts of putrescine, cadaverine, and tyramine were measured in vaginal washings from five patients with non-specific vaginitis (nsv) associated with gardnerella vaginalis, five patients with trichomoniasis, and five healthy controls. putrescine and cadaverine were present in all but one sample from the infected patients; tyramine was found in four of five samples from the women with nsv and in two of five samples from those with trichomoniasis. the mean cadaverine to putrescine ratio was signi ...19836604557
[diagnostic and epidemiologic significance of multinuclear and round forms of trichomonas vaginalis].trichomonas are analyzed in the material taken directly from the urogenital tract of male and female patients cultivated on roiron medium and using different methods for staining the preparations was carried out. it is observed that some of the preparations examined show round nuclear forms of t. vaginalis impossible the detect by laboratory methods used up to now. the techniques used in this study decrease the risk of false diagnosis of these forms of trichomoniasis by less experienced examiner ...19836605001

viability of trichomonas vaginalis in vitro at four temperatures.the effect of temperature as a possible factor on the survival of trichomonas vaginalis for shipment or routine laboratory maintenance was studied. ten strains of t. vaginalis, atcc 30001, atcc 30238, and eight clinical isolates, were examined for viability when kept incubated at 37 degrees c or removed from this temperature and held at 42, 22, or 5 degrees c for increasing lengths of time without subculture or reincubation at 37 degrees c. the order in which the strains remained viable without ...19836605364
purine salvage networks in giardia lamblia.purine metabolism in giardia lamblia was investigated by monitoring incorporation of radiolabeled precursors into purine nucleotides in the log-phase trophozoites cultivated in vitro in axenic media and incubated in buffered saline glucose. the lack of incorporation of formate, glycine, hypoxanthine, inosine, and xanthine into the nucleotide pool suggests the absence of de novo purine nucleotide synthesis and the inability to form imp as the precursor of amp and gmp in g. lamblia. only adenine, ...19836605408
