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 trichomonal pathogenesis. Herein, the effe...

Avian trichomoniasis caused by Trichomonas gallinae is a serious protozoan disease worldwide. The domestic pigeon (Columba livia domestica) is the main host for T. gallinae and plays an important role in the spread of the disease. Based on the internal transcribed spacers of nuclear ribosomal DNA of this parasite, a pair of primers (TgF2/TgR2) was designed and used to develop a PCR assay for th...

Trichomonas vaginalis is a pathogen that triggers severe immune responses in hosts. T. vaginalis α-actinin 2, Tvα-actinin 2, has been used to diagnose trichomoniasis. This study was undertaken to examine the role of Tvα-actinin 2 as an antigenic molecule to induce immune responses from humans. Western blot analysis using anti-Tvα-actinin 2 antibodies indicated its presence in the secreted prote...

PURPOSE To obtain reliable estimates of the sensitivity and specificity of the cervical Papanicolaou (Pap) smear and wet mount to diagnose vaginal trichomoniasis. METHODS Articles indexed in MEDLINE (1976-1998) about diagnostic tests for trichomoniasis and their listed references were retrieved. Thirty studies (9,501 patients) that used trichomonas culture as a gold standard were selected. St...

BACKGROUND Metronidazole is drug of choice recommended by WHO for treatment of trichomoniasis, however, some reports claims drug resistance in Trichomonas vaginalis isolates recently. The objective of this study was to determine the minimum lethal concentration (MLC) of metronidazole in resistant and sensitive strains, as well as genetic patterns of these stains by PCR method. METHODS From Fe...

Trichomonal infestation has spread in every continent, in every class, in every race and climate. It may be asked whether this is due to the misfortunes of war or to improved methods of detecting the organism. Does it affect the vagina or the whole uro-genital system? Is it acquired and transmitted solely by sexual contact? What are the different forms of T. vaginalis? Does the parasite infect ...

INTRODUCTION Microscopy of genital secretions is routinely performed in female patients attending genitourinary medicine clinics. It diagnoses only 50-70% of gonorrhoea, 40-80% of trichomoniasis and has no value in the diagnosis of chlamydial infection. This study was therefore conducted to reassess the role of routine microscopy in female patients. SUBJECTS AND METHODS One thousand consecuti...

In Iranian folk medicine Artemisia sieberi has been used for treatment of parasite infections in human and animals. The present study was designed to evaluate the in vitro and in vivo effects of A. sieberi essential oil (EO) against Trichomonas gallinae. Trichomonas gallinae were recovered by wet mount method from infected native pigeons. The in vitro assays were accomplished in multi-well plat...

BACKGROUND Cervical cancer is the predominant cancer among women in Kenya and second most common in women in developing regions. Population-based cytological screening and early treatment reduces morbidity and mortality associated with the cancer. We determined the occurrence of cervical precancerous changes and cervical microbial infections (Trichomonas vaginalis, Candida albicans, Neisseria g...
