In densely populated urban environments, the distribution of microbes and the drivers of microbial community assemblages are not well understood. In sprawling metropolitan habitats, the "urban microbiome" may represent a mix of human-associated and environmental taxa. Here we carried out a baseline study of automated teller machine (ATM) keypads in New York City (NYC). Our goal was to describe the biodiversity and biogeography of both prokaryotic and eukaryotic microbes in an urban setting while assessing the potential source of microbial assemblages on ATM keypads...

BACKGROUND: Trichomonas vaginalis is the most common curable sexually transmitted infection worldwide. Although the Centers for Disease Control and Prevention and the World Health Organization recommend a single 2-g dose of metronidazole for the first line of treatment for T. vaginalis among human immunodeficiency virus (HIV) negative women, high rates of repeat infections are found. The purpose of this meta-analysis was to compare treatment failure between single versus multidose metronidazole for the treatment of T...

Mycoplasma genitalium is an emerging agent of sexually-transmitted infection and is responsible for clinically-significant genital tract disease in both females and males. Similar to scenarios recently experienced with the urogenital flagellate Trichomonas vaginalis, an evolving molecular diagnostic reference standard based on transcription-mediated amplification allows for accurate detection of the organism, plus additional insight into disease epidemiology. Areas covered. The basis for this article includes primary peer-reviewed literature plus compilations of data derived from routine clinical laboratory screening of females and males for agents of sexually-transmitted infection...

BACKGROUND: Gonorrhoea is a common sexually transmitted infection which causes genital pain and discomfort; in women it can also lead to pelvic inflammatory disease and infertility, and in men to epididymo-orchitis. Current treatment is with ceftriaxone, but there is increasing evidence of antimicrobial resistance which is reducing its effectiveness against gonorrhoea. A small, but increasing, number of patients have already been found to have highly resistant strains of gonorrhoea which has been associated with clinical failure...

Muriel Robertson (1883-1973) was a pioneering protozoologist who made a staggering number of important contributions to the fields of parasitology, bacteriology and immunology during her career, which spanned nearly 60 years. These contributions were all the more remarkable given the scientific and social times in which she worked. While Muriel is perhaps best known for her work on the life cycle and transmission of the African trypanosome, Trypanosoma brucei, which she carried out in Uganda at the height of a major Sleeping Sickness epidemic, her work on the Clostridia during the First and Second World Wars made significant contributions to the understanding of anaerobes and to the development of anti-toxoid vaccines, and her work on the immunology of Trichomonas foetus infections in cattle, carried out in collaboration with the veterinarian W...

Trichomonas vaginalis causes the most common non-viral sexually transmitted disease worldwide. The cytoadherence and cytotoxicity upon the vaginal epithelial cells are crucial for the infection. Extracellular nucleotides are released during cell damage and, along with their nucleosides, can activate purinoceptors. The opposing effects of nucleotides versus nucleosides are regulated by ectonucleotidases. Herein we evaluated the hemolysis and cytolysis induced by T. vaginalis, as well as the extracellular nucleotide hydrolysis along with the effects mediated by nucleotides and nucleosides on cytotoxicity...

BACKGROUND: In Germany, local public health departments (LPHD) are required to offer low-threshold access to confidential counselling and testing for sexually transmitted infections (STI) for sex workers. We collected data from LPHD in Germany to estimate the number of performed STI tests and the proportion of positive STI tests among attending female sex workers (FSW) in order to formulate recommendations for improving STI testing and care for FSW in Germany. METHODS: We recruited LPHD across Germany to collect aggregated data on attending FSW between January 2010 and March 2011...

PURPOSE: Infection with and persistence of high-risk human papillomavirus (HR HPV) are the strongest risk factors for cervical cancer. Little is known about the prevalence and role of concurrent sexually transmitted infections (STIs) found in HPV-infected female sex workers (FSW) in Africa. This study purports to test our a priori hypotheses that STIs are associated with genotypes pertaining to the α-group species 9. The objectives were to determine the prevalence of bacterial vaginosis (BV), Trichomonas vaginalis, and Candida spp in FSW, the association between these STIs and the prevalence of any potential HR and HR HPV genotypes in FSWs...

Avian trichomonosis, caused by the flagellated protozoan parasite Trichomonas gallinae, has variable pathogenicity among bird species ranging from asymptomatic infections to severe disease periodically manifesting in epidemic mortality. Traditionally, columbids are identified as highly susceptible to infection with occasional spillover into raptors that prey on infected birds. We identified avian trichomonosis in two dead California spotted owls (Strix occidentalis occidentalis) and three dead northern spotted owls (S...

Pentatrichomonas hominis is an anaerobic flagellated protist that colonizes the large intestine of a number of mammals, including cats, dogs, nonhuman primates, and humans. The wide host range of this organism is alarming and suggests a rising zoonotic emergency. However, knowledge on in-depth biology of this protist is still limited. Similar to the human pathogen, Trichomonas vaginalis, P. hominis possesses hydrogenosomes instead of mitochondria. Studies in T. vaginalis indicated that hydrogenosome is essential for cell survival and associated with numerous pivotal biological functions, including drug resistance...

Comparative protein structure modeling predicts the three-dimensional structure of a given protein sequence (target) based primarily on its alignment to one or more proteins of known structure (templates). The prediction process consists of fold assignment, target-template alignment, model building, and model evaluation. This unit describes how to calculate comparative models using the program MODELLER and how to use the ModBase database of such models, and discusses all four steps of comparative modeling, frequently observed errors, and some applications...
