Hepatitis B core virus-like particles bearing Pgp3 antigen enhance immune response against genital chlamydial infection in mice.

Chlamydia trachomatis Pgp3 protein-induced immunoprotection is effective but incomplete, which requires the suitable adjuvants to enhance its immune response. Within this context, Hepatitis B core virus-like particles (HBc-VLP) emerge as nanoscale protein particles capable of incorporating either endogenous or exogenous antigens or epitopes. In this study, HBc-Pgp3 chimeric protein was accomplished by integrating the identified dominant epitope of the Pgp3 protein into the major immunodominant region of a truncated HBc-VLP, which was realized in the pET28a (+) vector and expressed via the E.

Chlamydia trachomatis infections in Kenya - sexually transmitted and ocular infections: a scoping review.

Background: (CT), a Gram-negative intracellular bacterium, is differentiated into three biovars associated with distinct clinical syndromes, ranging from trachoma, the world's cause of preventable blindness, to the most common sexually transmitted infection. This variability underscores CT's significant impact on public health, particularly in low-resource settings. In Kenya, where the demographic is predominantly younger, the burden of CT remains poorly understood and potentially underestimated.

Acute respiratory distress syndrome caused by : a case report and literature review.

Background: Psittacosis is a zoonotic disease with a low incidence rate and a lack of specificity in clinical manifestations, making it prone to be missed, misdiagnosed, and even cause delayed treatment for patients. Metagenomic next-generation sequencing (mNGS) was successfully performed for the diagnosis of a young patient with psittacosis progressing to acute respiratory distress syndrome (ARDS), and precisely targeted antibiotic treatment was promptly administered. Additionally, a comprehensive review was conducted on 68 cases of psittacosis complicated with ARDS, with the goal of improving the clinical awareness of this disease.

Molecular detection of in birds: a systematic review.

Molecular methods are currently the most sensitive for detecting in birds. Most laboratories have developed their own molecular assays or adapted published protocols, often making slight modifications to fit their specific study purposes. The sensitivity and specificity of a molecular test depend on the target genes, primer sequences, types of molecular tests, DNA extraction methods, and sampling methods.

Factors associated with bacterial sexually transmitted infection screening uptake and diagnosis among men who have sex with men in France.

Background: The prevalence of syphilis, Chlamydia trachomatis (CT), and Neisseria gonorrhoeae (NG) in men who have sex with men (MSM) is very high. As these bacterial sexually transmitted infections (bSTIs) are frequently asymptomatic, they are often undiagnosed and therefore untreated. We aimed to characterize the profile of MSM who reported bSTI screening and diagnosis in the previous 12 months, and to identify the factors associated with a diagnosis of a bSTI among MSM in France.

Dynamics of antibiotic resistance in poultry farms via multivector analysis.

This study examines the distribution of microbial communities and antibiotic resistance genes (ARGs) across various vectors in poultry farm environments. The results show that airborne particulate matter (PM) and soil harbor the highest counts of microbial genes, exceeding those found in poultry visceral samples, which display lower microbial diversity and ARG levels. This highlights environmental vectors, particularly soil and PM, as major reservoirs for ARGs.

Female Pelvic Conditions: Sexually Transmitted Infections.

Sexually transmitted infection rates are increasing in the United States, with significant increases in the rates of syphilis among patients of reproductive age and, subsequently, congenital syphilis. Syphilis screening is recommended in sexually active patients 15 to 44 years of age in communities with high syphilis rates and in all pregnant patients at the time of diagnosis or prenatal intake, in the third trimester, and at delivery. Screening for chlamydia and gonorrhea is currently recommended in asymptomatic, sexually active patients younger than 25 years, as well as in older patients with risk factors.

Regression analysis of group-tested current status data.

Group testing is an effective way to reduce the time and cost associated with conducting large-scale screening for infectious diseases. Benefits are realized through testing pools formed by combining specimens, such as blood or urine, from different individuals. In some studies, individuals are assessed only once and a time-to-event endpoint is recorded, for example, the time until infection.

We conducted a search using the terms "endometritis women" OR "female endometritis" OR "pelvic inflammatory disease" AND bacteria* OR "uterine microbiome" in two databases: PubMed and Web of Science, without language or publication year restrictions. The panel is based on an analysis of 40 studies published over the past 38 years.

Could APTIMA mRNA Assay Contribute to Predicting Cervical Bacterial Sexually Transmitted Co-Infections? A Colposcopy Population Study.

In addition to chronic hrHPV anogenital infection, continuing inflammatory cervical changes are intrinsic in the development of precancerous lesions. In younger women, much of this inflammatory background parallels the progressive maturation of squamous metaplasia, often rendering treatment interventions redundant; however, patients with persistent cervical precancer, as well as those harboring invasive bacterial pathogens, might benefit from controlling the active inflammatory process by shortening the HPV natural cycle and avoiding subsequent cervical surgery. In a colposcopy population of 336 predominantly young asymptomatic individuals, we explored the impact of molecularly detected bacterial STIs on HPV DNA and APTIMA positivity rates using validated assays.

Sexual wellness clinic collaborative initiative with a large urban emergency department: sexual health outcomes and linkage to HIV pre-exposure prophylaxis.

Introduction: Despite escalating rates of sexually transmitted infections (STIs) in the United States (US), there has been progressive divestment of sexual health services leading to the reliance on emergency departments (EDs) for sexual healthcare, particularly among vulnerable populations. The Sexual Wellness Clinic (SWC), a novel care delivery model operating in collaboration with the ED, offers comprehensive sexual health services.

Objectives: This study aims to analyze the demographics, STI positivity, and HIV Pre-Exposure Prophylaxis (PrEP) uptake among patients accessing the SWC.

The SWIB domain-containing DNA topoisomerase I of mediates DNA relaxation.

The obligate intracellular bacterial pathogen, (Ct), has a distinct DNA topoisomerase I (TopA) with a C-terminal domain (CTD) homologous to eukaryotic SWIB domains. Despite the lack of sequence similarity at the CTDs between TopA (CtTopA) and TopA (EcTopA), full-length CtTopA removed negative DNA supercoils and complemented the growth defect of an mutant. We demonstrated that CtTopA is less processive in DNA relaxation than EcTopA in dose-response and time course studies.
