| growth of trichomonas vaginalis in a serum-free mccoy cell culture system. | axenic cultures of trichomonas vaginalis normally require serum for proliferation, yet serum-containing medium may interfere with the detection of t. vaginalis-secreted virulence factors. trichomonas vaginalis can, however, grow in coculture with a mccoy cell monolayer in both the presence and absence of serum. for 6 t. vaginalis isolates examined, growth in this serum-free system shows lower peak concentrations of t. vaginalis and longer doubling times than those apparent in a serum-containing ... | 1990 | 2254829 |
| characterization of trichomonas vaginalis haemolysis. | the haemolytic activity of live trichomonas vaginalis organisms was investigated. optimal haemolysis of human erythrocytes was observed at a parasite to erythrocyte ratio of 1:5 during a 2 h incubation period. no haemolytic activity was detected in concentrated culture supernatants after overnight growth of trichomonads or when parasites were separated from erythrocytes by a 3 microns filter, suggesting a contact-dependent mechanism for haemolysis. the haemolytic activity was temperature-depende ... | 1990 | 2263411 |
| dot-immunobinding assay with monoclonal antibody for detection of trichomonas vaginalis in clinical specimens. | a rapid and specific dot-enzyme immunoassay (diba) using monoclonal antibody was introduced for detection of trichomonas vaginalis antigen in vaginal and urethral materials. the results of diba were compared with culture findings of the parasite in 245 female patients. taking culture as the reference method, diba had a sensitivity of 92% and a specificity of 93%. the predictive value of a positive test was 98% and that of a negative test 77%. the efficacy of wet mount, culture and diba were comp ... | 1990 | 2265844 |
| [detection of igg and igm antibodies with elisa technique in human trichomoniasis]. | the direct wet mount examination of vaginal secretion, widely applied for the diagnosis of trichomonas vaginalis infection in woman patients, is rapid and economical, however, the sensitivity of this technique is not so high. in this study enzyme-linked immunosorbent assay (elisa) was employed for the detection of serum anti-t. vaginalis igg and igm antibodies from 30 vaginal trichomoniasis patients and 30 non-infected healthy persons. the results were as follows: 1. serum elisa-igg value was 0. ... | 1990 | 2271497 |
| histopathology of endocervical infection caused by chlamydia trachomatis, herpes simplex virus, trichomonas vaginalis, and neisseria gonorrhoeae. | we determined the histologic correlates of clinically identified mucopurulent cervicitis, culture-proven cervical infection with chlamydia trachomatis, neisseria gonorrhoeae, herpes simplex virus (hsv), and vaginal infection with trichomonas vaginalis by examining cervical biopsies from 83 women. clinical mucopurulent cervicitis and culture-documented infection with one or more of these pathogens correlated histologically with intraepithelial neutrophils, reactive endocervical cells, edema, lumi ... | 1990 | 2387574 |

| characteristics of trichomonas vaginalis isolates from women with and without colpitis macularis. | colpitis macularis, the most specific clinical sign for diagnosis of trichomoniasis, was detected by colposcopy in 52 of 118 infected women. patients with colpitis macularis had a mean (+/- sd) of 18 +/- 20 trichomonas vaginalis organisms/field (x 400 magnification) compared with 7 +/- 17 in patients with colpitis macularis (p less than .003). to compare possible virulence markers in isolates from women with and without colpitis macularis, isolates were analyzed for hemolytic activity, abscess p ... | 1990 | 2299210 |
| geographic variation among isolates of trichomonas vaginalis: demonstration of antigenic heterogeneity by using monoclonal antibodies and the indirect immunofluorescence technique. | although trichomonas vaginalis causes one of the most common sexually transmitted diseases, little is known about the antigenic variation of the parasite or about differences between strains in epidemiology or virulence. variation among isolates of t. vaginalis was investigated by using a panel of monoclonal antibodies, each reactive with different antigens, to test 88 isolates from diverse geographic areas of north america. all isolates of t. vaginalis reacted with at least one of the nine mono ... | 1985 | 2413147 |
| transvaginal-peritoneal migration of trichomonas vaginalis as a cause of ascites. a report of two cases. | genital tract colonization with trichomonas vaginalis usually results in vaginitis without systemic manifestations. there are only four recorded cases of trichomonas recovered from pelvic organs or peritoneal fluid. this report describes two additional women in whom motile flagellate organisms were recovered from abdominopelvic ascites. we hypothesize that an ascending trichomonal infection may have played an etiologic role in the development of their acute disease. | 1990 | 2304041 |
| the specificity of trichomonad cysteine proteinases analysed using fluorogenic substrates and specific inhibitors. | the multiple cysteine proteinases of trichomonas vaginalis and tritrichomonas foetus, both those retained intracellularly and those released, were separated using gelatin-sds-page, and their activity towards a range of 15 fluorogenic peptidyl aminomethylcoumarins determined together with their relative sensitivity to inhibitors. three types of enzyme were apparent in t. vaginalis: (i) an 86-kda enzyme active only on z-arg-arg-nhmec; (ii) a 54-kda proteinase which was most active on z-phe-arg-nhm ... | 1990 | 2320056 |
| phenotypic variation and diversity among trichomonas vaginalis isolates and correlation of phenotype with trichomonal virulence determinants. | the extent and nature of heterogeneity among representative trichomonas vaginalis isolates were evaluated by flow cytofluorometry analysis. monoclonal antibody and monospecific antiserum to an immunodominant trichomonad surface glycoprotein with a molecular weight of 267,000 (267k glycoprotein) were used to evaluate fresh isolates (jhh and ru375) and long-term grown isolates (nyh286, ir78, and jh31a) of t. vaginalis. isolates nyh286, jh31a, and jhh were made up of heterogeneous staining (positiv ... | 1986 | 2426199 |
| [the effect of nitrofuran and asymmetrically substituted urea on trichomonas vaginalis and tritrichomonas foetus in vitro and in vivo]. | antitrichomonal activity of selected nitrofuran derivatives and asymmetrically substituted ureas was investigated in vitro and in vivo and compared with the activity of the effective therapeutic agent tinidazole. in experimental infection with trichomonas vaginalis and tritrichomonas foetus in mice, some substituted urea derivatives exhibited an antiparasitic effect slightly lower than that of tinidazole. the substance n1-(3-nitrophenyl)-n3-(2-pyrimidinyl)urea proved to be the most effective of ... | 1990 | 2322865 |
| inhibition of pyruvate:ferredoxin oxidoreductase from trichomonas vaginalis by pyruvate and its analogues. comparison with the pyruvate decarboxylase component of the pyruvate dehydrogenase complex. | pyruvate:ferredoxin oxidoreductase and the pyruvate dehydrogenase multi-enzyme complex both catalyse the coa-dependent oxidative decarboxylation of pyruvate but differ in size, subunit composition and mechanism. comparison of the pyruvate:ferredoxin oxidoreductase from the protozoon trichomonas vaginalis and the pyruvate dehydrogenase component of the escherichia coli pyruvate dehydrogenase complex shows that both are inactivated by incubation with pyruvate under aerobic conditions in the absenc ... | 1990 | 2188649 |
| cdna sequence analysis of a 29-kda cysteine-rich surface antigen of pathogenic entamoeba histolytica. | a gamma gt11 cdna library was constructed from poly(u)-sepharose-selected entamoeba histolytica trophozoite rna in order to clone and identify surface antigens. the library was screened with rabbit polyclonal anti-e. histolytica serum. a 700-base-pair cdna insert was isolated and the nucleotide sequence was determined. the deduced amino acid sequence of the cdna revealed a cysteine-rich protein. dna hybridizations showed that the gene was specific to e. histolytica since the cdna probe reacted w ... | 1990 | 2201027 |
| glucokinase and fructokinase of trichomonas vaginalis and tritrichomonas foetus. | trichomonas vaginalis and tritrichomonas foetus contain glucokinase and not a hexokinase of broad hexose specificity. tritrichomonas foetus also contains a specific fructokinase which could be resolved from glucokinase by anion exchange chromatography. native t. vaginalis glucokinase had a mr of 76,000, and sds-pag electrophoresis showed two equally stained bands corresponding to mr 40,000 and 38,000. glucose and atp were by far the best substrates for both trichomonad glucokinases, with km valu ... | 1990 | 2213652 |
| diagnosis of chlamydia trachomatis infection--culture versus serology. | the diagnostic value of different laboratory methods in detecting chlamydia trachomatis infections in high risk groups was analysed. the efficiency of a direct specimen test was compared with serology (igg and igm elisa) and culture in l929 cells, stained either with fluorescein conjugated monoclonal antibodies or with iodine. patients (no. = 1041) with localized genital infections attending a std clinic, sexual contacts and patients with ascending infections from urological and gynecological cl ... | 1988 | 2451616 |
| [bound amino acids in local strains of trichomonas vaginalis]. | amino acid composition of water-soluble and water-insoluble proteins of 8 strains of tr. vaginalis is studied. 17 amino acids are found in both protein hydrolyzates. despite the complete coincidence of their qualitative compositions there are reliable differences in the quantitative contents of some amino acids. differences in the contents of main amino acids of water-soluble proteins of different strains reflect the belonging of the latter to different sero-groups. no reliable differences in th ... | 1990 | 2216532 |
| reduced lymphocyte responses to mitogens in natural and experimental trichomoniasis. | proliferative responses to mitogens were determined by using peripheral blood mononuclear cells from women with active trichomoniasis, with serological evidence of past infection with trichomonas vaginalis, and with no evidence of current or past infection. even after the human immunodeficiency virus antibody status of the patients was taken into account, cells from women with active trichomoniasis showed reduced responses to phytohemagglutinin, concanavalin a, pokeweed mitogen, and bacterial li ... | 1990 | 2228226 |
| antioxidant enzymes in trichomonas vaginalis. | the activities of artificial donor peroxidase, catalase, and superoxide dismutase in clinical isolates of t. vaginalis were studied. none of the tested strains exhibited activity of the three enzymes. inclusion of catalase in diamond-tym solid medium did not support growth under aerobic conditions. the correlation between the absence of these enzymes and the growth conditions of the organism is discussed. | 1990 | 2230334 |
| semen characteristics of asymptomatic males affected by trichomonas vaginalis. | trichomonas vaginalis is a sexually transmitted anaerobic parasite which causes vaginitis and cervicitis. the present study was carried out to determine the incidence of trichomonas infection in semen samples of asymptomatic men and also to understand the changes of semen characteristics in the infected individuals before treatment and after treatment with metronidazole (flagyl, 400 mg x 3x a day for 10 days). the semen obtained from 1131 men was examined for different characteristics and tricho ... | 1990 | 2380623 |
| rapid eradication of trichomonads by single-dosed nimorazole. | previous in vitro studies demonstrated the rapidity of trichomonacidal action of nimorazole (naxogin 500) which was twice that of metronidazole and many times that of tinidazole. since rapid eradication of parasites can lead to a significant decrease in transmission rate, and hence, a lower prevalence of this sexually transmitted disease, a pilot study was designed to investigate the in vivo speed of action of nimorazole. twenty females with positive wet smears for trichomonas vaginalis were tre ... | 1990 | 2380642 |
| persistent vaginitis caused by metronidazole-resistant trichomonas. | persistent trichomonal vaginitis is usually considered the result of either patient noncompliance with therapy or reinfection. drug-resistant trichomoniasis may also cause continued infection despite repeated courses of conventional metronidazole therapy. we report two cases of exceptionally persistent and prolonged infection despite repetitive and varied treatments, including parenteral metronidazole. an unconventional approach combining oral and topical therapy resulted in clinical and microbi ... | 1990 | 2381638 |
