This prospective observational study aims to determine the incidence, predictors and clinical features of Mycoplasma hominis (MH), Ureaplasma urealyticum (UU) and Chlamydia trachomatis (CT) respiratory colonization in infants <37 weeks of gestation. A total of 200 preterm newborns admitted to a tertiary center in Malaysia between 2013 and 2015 for increased breathing effort had their respiratory secretions tested for these bacteria by polymerase chain reaction. Fifteen of the 200 (7.5%) infants were detected to have these organisms in their respiratory tracts...

Using simulations of Mn/Fe K-edge X-ray absorption spectroscopy (XAS), combined with DFT-optimized structural models and direct comparisons with available experimental data, we determine geometrical and electronic properties of the Mn-Fe active site of Chlamydia trachomatis (Ct) of ribonucleotide reductase (RNR). In the post-edge XAS energy range, we use extended X-ray absorption fine structure (EXAFS) data, to acquire absorber-scatterer geometrical information around each absorber metal center. For this task, we apply a protocol that evaluates Debye-Waller factors in scattering paths instead of scattering shells to fit the experimental EXAFS...

The risk of zoonoses spreading from birds to humans is lower, quantitatively speaking, than the risk of transmission between other host groups, because the two taxonomic groups share fewer pathogens. Nevertheless, birds have a number of epidemiological characteristics that make them extremely important hosts in the transmission and maintenance of zoonoses, including their susceptibility to pathogens that are extremely hazardous to humans (such as highly pathogenic avian influenza virus, West Nile virus and Chlamydia psittaci) and their ability to travel long distances, especially in the case of migratory birds...

Recruitment for HIV research among gay, bisexual, and other men who have sex with men (MSM) has increasingly moved to the online sphere. However, there are limited data comparing the characteristics of clinic-based respondents versus those recruited via online survey platforms. MSM were recruited from three sampling sites (STI clinic, MTurk, and Qualtrics) to participate in a survey from March 2015 to April 2016. Respondents were compared between each of the sampling sites on demographics, sexual history, substance use, and attention filter passage...

Obligate intracellular bacteria such as Chlamydia trachomatis depend on metabolites of the host cell and thus protect their sole replication niche by interfering with the host cells' stress response. Here, we investigated the involvement of host microRNAs (miRNAs) in maintaining the viability of C. trachomatis-infected primary human cells. We identified miR-30c-5p as a prominently up-regulated miRNA required for the stable down-regulation of p53, a major suppressor of metabolite supply in C. trachomatis-infected cells...

BACKGROUND: Chlamydia trachomatis (chlamydia) is the most commonly diagnosed sexually transmitted infection (STI) in England; approximately 70% of diagnoses are in sexually active young adults aged under 25. To facilitate opportunistic chlamydia screening in general practice, a complex intervention, based on a previously successful Chlamydia Intervention Randomised Trial (CIRT), was piloted in England. The modified intervention (3Cs and HIV) aimed to encourage general practice staff to routinely offer chlamydia testing to all 15-24 year olds regardless of the type of consultation...

The human oral cavity contains more than 500 different bacterial species. These organisms belong to several phyla including Bacteroidetes, Firmicutes, Tenericutes, Actinobacteria, Proteobacteria, Euryarchaeota, Chlamydiae, and Spirochaetes. Many of these have the ability to colonize the gingival crevices and the outer surface of the tooth forming biofilms often leading to dental plaque formation. These bacteria produce acid that erode teeth causing cavities or infections. The diagnosis of these infections is often clinical and antibiotics are used empirically to treat some infections or as prophylaxis...

Chlamydia trachomatis and HPV coinfections in the male population are often a disregarded issue. We performed a study to evaluate the prevalence of such infections in heterosexual HIV negative men from a Northern Italy multi-ethnic area at high prevalence for cervical malignancies. Urethral swabs (US) or first-voided urine were evaluated retrospectively from 1317 patients attending Sexually Transmitted Infections (STI) clinic and from 3388 outpatients attending private clinics. Informations about participants' demographic characteristics and attributes of Chlamydia trachomatis, including chronic infection, and HPV genotypes testing, were collected...

BACKGROUND: Understanding patterns of chlamydia prevalence is important for addressing inequalities and planning cost-effective control programs. Population-based surveys are costly; the best data for England come from the Natsal national surveys, which are only available once per decade, and are nationally representative but not powered to compare prevalence in different localities. Prevalence estimates at finer spatial and temporal scales are required. METHODS: We present a method for estimating local prevalence by modeling the infection, testing and treatment processes...

CONTEXT: Human papillomavirus (HPV) and Chlamydia trachomatis are the most frequent sexually transmitted infections, usually asymptomatic. Persistent infection with high-risk HPV types and other cofactors such as the concomitant infection with C. trachomatis can represent a higher risk to develop cervical lesions; therefore, screening with sensitive methods could aid to identify women at risk. AIMS: The aim is to determine the prevalence and concurrence of both infections, detected with in-house molecular methods, and to identify the risk factors associated to the infections in Mexican women...

Urogenital infection due to Chlamydia trachomatis (CT) is one of the most common bacterial sexually transmitted infections (STIs) and is a major public health problem worldwide. Molecular characterisation of CT is important for understanding the pathophysiological mechanisms of chlamydial disease and its transmission dynamics in sexual networks. Traditionally, strain typing of CT was based on serotyping methods characterising the major outer membrane protein (MOMP). With the advent of polymerase chain reaction and sequencing the era of molecular typing began...

The community structure of bacteria associated with the glacier ice worm Mesenchytraeus solifugus was analyzed by amplicon sequencing of 16S rRNA genes and their transcripts. Ice worms were collected from two distinct glaciers in Alaska, Harding Icefield and Byron Glacier, and glacier surfaces were also sampled for comparison. Marked differences were observed in bacterial community structures between the ice worm and glacier surface samples. Several bacterial phylotypes were detected almost exclusively in the ice worms, and these bacteria were phylogenetically affiliated with either animal-associated lineages or, interestingly, clades mostly consisting of glacier-indigenous species...
