One-year monitoring of potentially pathogenic microorganisms in the waters and sediments of the Lesina and Varano lagoons (South-East Italy).

In this study, two Mediterranean coastal lagoons (Lesina and Varano) of southern Italy, located in the north of the Apulia region, were investigated for the presence of Shiga toxin (STEC) and potentially enteropathogenic species in parallel with norovirus (NoV), hepatitis A virus (HAV), hepatitis E virus (HEV), and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This study aimed to evaluate the presence of potentially pathogenic bacteria and viruses in the water and sediments of these ecosystems. From March 2022 to February 2023, a total of 98 samples were collected: 49 water samples and 49 sediment samples.

Duplex Droplet Digital PCR Assay for Quantification of Hepatitis E Virus in Food.

Hepatitis E virus (HEV) represents an emerging risk in industrialized countries where the consumption of contaminated food plays a pivotal role. Quantitative real-time RT-PCR (RT-qPCR) is one of the most suitable methods for the detection and quantification of viruses in food. Nevertheless, quantification using RT-qPCR has limitations.

-Acting Element at the 5' Noncoding Region of Tacaribe Virus S RNA Modulates Genome Replication.

Tacaribe virus (TCRV) is the prototype of New World mammarenaviruses, a group that includes several members that cause hemorrhagic fevers in humans. The TCRV genome comprises two RNA segments, named S (small) and L (large). Both genomic segments contain noncoding regions (NCRs) at their 5' and 3' ends.

Validation of the Italian version of the spirituality and spiritual care rating scale (SSCRS-ita).

Purpose: To translate and validate the Italian version of the Spirituality and Spiritual Care Rating Scale (SSCRS-ita).

Methods: A single-center cross-sectional study was performed from October 15 to November 15, 2019 in a public hospital in Milan, Italy. The scale was drafted using the back-translation method.

Fractional CO2 laser and vulvar lichen sclerosus: an alternative resource during maintenance therapy? A prospective study.

Background: Lichen sclerosus is an autoimmune dermatosis that in women typically involves vulvar area. This condition can strongly impact on the quality of life. To date, topical steroids are the most effective treatment, although adverse effects are possible, especially in long-term application.

Optimized Adenoviral Vector That Enhances the Assembly of FMDV O1 Virus-Like Particles Increases Its Potential as Vaccine for Serotype O Viruses.

Although replication-defective human adenovirus type 5 (Ad5) vectors that express the capsid-encoding region of foot-and-mouth disease virus (FMDV) have been proven to be effective as vaccines in relevant species for several viral strains, the same result was not consistently achieved for the O1/Campos/Brazil/58 strain. In the present study, an optimization of the Ad5 system was explored and was proven to enhance the expression of FMDV capsid proteins and their association into virus-like particles (VLPs). Particularly, we engineered a novel Ad5 vector (Ad5[P]) which harbors the foreign transcription unit in a leftward orientation relative to the Ad5 genome, and drives the expression of the FMDV sequences from an optimized cytomegalovirus (CMV) enhancer-promoter as well.

Pharyngeal microbiome alterations during Neisseria gonorrhoeae infection.

Pharyngeal gonorrhoea is a common sexually transmitted infection among 'men having sex with other men' (MSM). Neisseria gonorrhoeae (NG) pharyngeal infections are usually characterized by the absence of symptoms, acting as an important reservoir for their further spread. To the best of our knowledge, no information about the composition of the pharyngeal microbiome during an ongoing NG infection is currently available.

Rectal Microbiota Associated With and Infections in Men Having Sex With Other Men.

(CT) and (NG) represent the most common agents of sexually transmitted rectal infections among men having sex with other men (MSM). In this study, we assessed the bacterial composition of the rectal microbiota associated with CT and/or NG infections in a cohort of men reporting unsafe rectal intercourse. A total of 125 rectal swabs were collected and four groups were compared: non-infected subjects ( = 53), patients with CT ( = 37), or NG rectal infection ( = 17) and patients with contemporary positivity for CT/NG ( = 18).

Diversity of vaginal microbiome and metabolome during genital infections.

We characterized the vaginal ecosystem during common infections of the female genital tract, as vulvovaginal candidiasis (VVC, n = 18) and Chlamydia trachomatis infection (CT, n = 20), recruiting healthy (HC, n = 21) and bacterial vaginosis-affected (BV, n = 20) women as references of eubiosis and dysbiosis. The profiles of the vaginal microbiome and metabolome were studied in 79 reproductive-aged women, by means of next generation sequencing and proton based-nuclear magnetic resonance spectroscopy. Lactobacillus genus was profoundly depleted in all the genital infections herein considered, and species-level analysis revealed that healthy vaginal microbiome was dominated by L.

Syphilis in a high-density urban area in the North of Italy.

Although far less common now than in the past, syphilis continues to pose a danger to public health and should not be overlooked. In this study, we evaluated the presence and characteristics of syphilis in a group of patients attending an STI Clinic in the North of Italy. A retrospective study was carried out, analysing the data from the 5609 subjects who attended the STI Clinic of St.

Virus⁻Host Interactions Involved in Lassa Virus Entry and Genome Replication.

Lassa virus (LASV) is the causative agent of Lassa fever, a human hemorrhagic disease associated with high mortality and morbidity rates, particularly prevalent in West Africa. Over the past few years, a significant amount of novel information has been provided on cellular factors that are determinant elements playing a role in arenavirus multiplication. In this review, we focus on host proteins that intersect with the initial steps of the LASV replication cycle: virus entry and genome replication.

Insights Into Vaginal Bacterial Communities and Metabolic Profiles of Infection: Positioning Between Eubiosis and Dysbiosis.

The vaginal microbiota plays a crucial role in maintaining the health and functioning of the female genital tract, preventing the colonization of urogenital pathogens and sexually transmitted infections. In this study, we characterized the vaginal bacterial communities and the metabolome associated to infection (CT: 20 women), compared to healthy condition (H: 22 women) and bacterial vaginosis (BV: 19 women). A microarray-based tool (VaginArray), implemented with a real-time PCR for , was used to determine the vaginal bacterial composition, whereas the metabolic profiles were assessed by a proton-based nuclear magnetic resonance (H-NMR) spectroscopy.
