BACKGROUND: Mycoplasma genitalium (MG) and Trichomonas vaginalis (TV) are common sexual transmitted infections (STI). However, most STI screening programmes do not include routinely detection of these pathogens. Consequently, epidemiological data about MG and TV in the general population is lacking. The current study aims to give insight into the prevalence of both infections, thereby guiding decisions whether testing for these pathogens should be included routinely. METHODS: Between February 2013 and August 2015, all samples sent to the laboratory of Diakonessenhuis Utrecht for STI testing (i...

The increased prevalence of metronidazole-resistant infections has resulted in a search for alternative drugs for the treatment of trichomoniasis. In the present study, we report the preparation and in vitro activity of three 1,3-dioxolanes that contain tellurium (PTeDOX 01, PTeDOX 02, and PTeDOX 03) against Trichomonas vaginalis. Six concentrations of these compounds were analyzed for in vitro activity against ATCC 30236 isolate of T. vaginalis. PTeDOX 01 reported a cytotoxic effect against 100% of T. vaginalis trophozoites at a final concentration of 90μM with an IC50 of 60μM...

PURPOSE OF REVIEW: This review aims to determine the effectiveness of the use of syndrome diagnosis in the evaluation of vaginitis and to make suggestions based on the review findings. RECENT FINDINGS: Vaginal discharge as the main symptom of vaginitis is unspecific. A randomized study of symptom-based diagnosis and treatment of vaginitis in the USA favored symptoms used for treatment; however, this was only a pilot study. Hence, a population-based study is necessary to validate these findings...

BACKGROUND: Human trichomoniasis caused by Trichomonas vaginalis is one of the most common sexually transmitted diseases with more than 200 million cases worldwide. It has caused a series of health problems to patients. For prevention and control of infectious diseases, vaccines are usually considered as one of the most cost-efficient tools. However, until now, work on the development of T. vaginalis vaccines is still mainly focused on the screening of potential immunogens. Alpha-actinin characterized by high immunogenicity in T...

To date there is no commercially-available serodiagnostic for women and men infected with Trichomonas vaginalis. Thirteen epitopes of the immunogenic T. vaginalis α-actinin (106.2-kDa) are detected by sera of women patients, and 5 epitopes, a subset of the 13, are detected by sera of men. A truncated recombinant protein called ACT-P2 (63.5-kDa) encoding the 5 epitopes is used for screening by ELISA for antibody in sera of women and men. Because ACT-P2 is poorly expressed in E. coli, we wanted alternative recombinant α-actinin proteins as serodiagnostic targets...

Trichomonas vaginalis is a major of non-viral sexually-transmitted infection and an important cause of serious obstetrical and gynecological complications. Treatment options for trichomoniasis are limited to nitroimidazole compounds. The increasing resistance and allergic reactions to nitroimidazole and recurrent trichomoniasis make it essential to identify and develop new drugs against trichomoniasis. Medicinal plants are an important source for discovery of new medications. This review discusses the anti-trichomonas effects of medicinal plants and their chemical constituents to find better options against this pathogenic protozoon...

INTRODUCTION: Adolescents are at high risk for acquiring and becoming re-infected with sexually transmitted infections (STIs). Partner notification and treatment are essential to preventing the spread of STIs. Expedited partner therapy (EPT) is a method of partner treatment utilized by medical providers to treat patients' sexual partners without direct medical evaluation or counseling. OBJECTIVE: The objective of this article is to review the current literature regarding EPT effectiveness, patients' attitudes and acceptance of EPT, and providers' views and practices surrounding the use of this method of partner treatment...

Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), and Trichomonas vaginalis (TV) are sexually transmitted infections (STIs) associated with adverse birth outcomes. Untreated partners contribute to high rates of STI reinfection; thus, partner notification and treatment remain important components of STI care and control. A prospective cohort study was conducted among 300 pregnant women presenting to the antenatal clinic at Princess Marina Hospital in Gaborone, Botswana who enrolled in an STI screening study...

Trichomoniasis, caused by the parasitic protozoan Trichomonas vaginalis, is the most common non-viral sexually-transmitted disease, and there can be severe complications from trichomoniasis. Antibiotic resistance in T. vaginalis is increasing, but there are currently no alternatives treatment options. There is a need to discover and develop new chemotherapeutic alternatives. Plant-derived natural products have long served as sources for new medicinal agents, as well as new leads for drug discovery and development...
