13. Iron from haemoglobin and haemin modulates nucleotide hydrolysis inTrichomonas vaginalis
Extracellular ATP may act as a danger signalling molecule, inducing inflammation and immune responses in infection sites. The ectonucleotidases NTPDase and ecto-5’-nucleotidase are enzymes that modulate extracellular nucleotide levels; these enzymes have been previously characterised in Trichomonas vaginalis. Iron plays an important role in the complex tri

14. The efficacy of 2-nitrovinylfuran derivatives againstLeishmania in vitro and in vivo
Despite recent advances in the treatment of some forms of leishmaniasis, the available drugs are still far from ideal due to inefficacy, parasite resistance, toxicity and cost. The wide-spectrum antimicrobial activity of 2-nitrovinylfuran compounds has been described, as has their activity against Trichomonas vaginalis and other protozoa. Thus, the aim of th

15. Salacia crassifolia (Celastraceae): CHEMICAL CONSTITUENTS AND ANTIMICROBIAL ACTIVITY
The phytochemical study of hexane extract from leaves of Salacia crassifolia resulted in the isolation of 3β-palmitoxy-urs-12-ene, 3-oxofriedelane, 3β-hydroxyfriedelane, 3-oxo-28-hydroxyfriedelane, 3-oxo-29-hydroxyfriedelane, 28,29-dihydroxyfriedelan-3-one, 3,4-seco-friedelan-3-oic acid, 3β-hydroxy-olean-9(11):12-diene and the mixture of α-amirin and β-

16. Trichomonas vaginalis infection among young pregnant women in Brazil
Our goal was to determine the prevalence of Trichomonas vaginalis and its associated risk factors in parturient women aged 15–24 years attending Brazilian public maternity units. Participants answered a demographic, behavioral, and clinical data questionnaire. A sample of urine was screened for T. vaginalis. A total 299 women participated in this study. Th

17. Isolation and antitrichomonal activity of the chemical constituents of the leaves of Maytenus phyllanthoides Benth. (Celastraceae)
Cyclolignan (+)-lyoniresinol (1), veratric acid (2), vanillic acid (3), lupeol, oleanolic acid, 3β-hydroxy-urs-11-en-28,13β-lactone (4), the mixture of α- and β-amyrin, trans-polyisoprene, and β-sitosterol were isolated from the leaves of Maytenus phyllanthoides. The structures of the isolated compounds were established based on spectroscopic data, main

18. Trichomonas vaginalis and associated factors among women living with HIV/AIDS in Amazonas, Brazil
OBJECTIVES: Our goal was to determine the prevalence of Trichomonas vaginalis and its associated factors among women living with HIV attending an AIDS clinic in Manaus, Amazonas, Brazil. METHODS: Cross-sectional study among women attending an AIDS clinic in Manaus between March and December 2010 for gynecological examination were invited to participate. Enro

19. IL-10 release by bovine epithelial cells cultured with Trichomonas vaginalis and Tritrichomonas foetus
Trichomonas vaginalis and Tritrichomonas foetus are parasitic protists of the human and bovine urogenital tracts, respectively. Several studies have described the cytotoxic effects of trichomonads on urogenital tract epithelial cells. However, little is known about the host cell response against trichomonads. The aim of this study was to determine whether T.

21. Trichomonas vaginalis and Tritrichomonas foetus: interaction with fibroblasts and muscle cells - new insights into parasite-mediated host cell cytotoxicity
Trichomonas vaginalis and Tritrichomonas foetus are parasitic, flagellated protists that inhabit the urogenital tract of humans and bovines, respectively. T. vaginalis causes the most prevalent non-viral sexually transmitted disease worldwide and has been associated with an increased risk for human immunodeficiency virus-1 infection in humans. Infections by

22. Validation of a modified fluorimetric assay for the screening of trichomonacidal drugs
A fluorimetric microassay that uses a redox dye to determine the viability of the flagellate Trichomonas vaginalis has been optimised to provide a more sensitive method to evaluate potential trichomonacidal compounds. Resazurin has been used in recent years to test drugs against different parasites, including trichomonadid protozoa; however, the reproducibil

23. Mycoplasmateceae species are not found in Fallopian tubes of women with tubo-peritoneal infertility
BACKGROUND: The role of mycoplasmas on the development and sequelae of pelvic inflammatory disease remains controversial. The objective of the present study is to correlate directly the presence of Mycoplasmateceae through polimerase chain reaction (PCR) determinations in cervix and Fallopian tubes of infertile patients with tubo-peritoneal factor diagnosed
