Since May 2022, an outbreak of monkeypox has been ongoing in non-endemic countries. We report four cases Italy young adult men reporting condomless sexual intercourse. The patients are good clinical condition with no need for specific antiviral drugs. Biological samples from seminal fluid were positive viral DNA. For many other viruses found semen there is evidence transmission. possibility transmission virus needs to be investigated.
Since December 2019, SARS-CoV-2 infection has been still rapidly spreading, resulting in a pandemic, followed by an increasing number of cases countries throughout the world. The severity disease depends on patient's overall medical condition but no appropriate markers are available to establish prognosis patients. We performed 16S rRNA gene sequencing, revealing altered composition nasal/oropharyngeal (NOP) microbiota 21 patients affected COVID-19, paucisymptomatic or Intensive Care Unit...
COronaVIrus Disease-2019 (COVID-19) is a pandemic respiratory infection caused by new betacoronavirus, the Severe Acute Respiratory Syndrome-CoronaVirus-2 (SARS-CoV-2). Few data are reported on gut microbiota in COVID-19 patients. 16S rRNA gene sequencing was performed to reveal an altered composition of patients with pneumonia admitted intensive care unit (ICU) (i-COVID19), or infectious disease wards (w-COVID19) as compared controls (CTRL). i-COVID19 showed decrease Chao1 index CTRL and...
Between August and September 2023, three distinct autochthonous dengue virus transmission events occurred in Lazio, Italy, with the main event Rome. The involved different serotypes. No link previous imported cases was identified. Here we describe epidemiological phylogenetic analysis of first implemented control actions. multiple call for a strengthening vector strategies future research to better characterise risk countries like Italy.
We report whole-genome and intra-host variability of SARS-Cov-2 assessed by next generation sequencing (NGS) in upper (URT) lower respiratory tract (LRT) from COVID-19 patients. The aim was to identify possible tissue-specific patterns signatures variant selection for each compartment. Six patients, admitted the Intensive Care Unit, were included study. Thirteen URT LRT analyzed NGS amplicon-based approach on Ion Torrent Platform. Bioinformatic analysis performed using both realized in-house...
Abstract We report phylogenetic and mutational analysis of severe acute respiratory syndrome coronavirus 2 virus strains from the Lazio region Italy provide information about dynamics spread. Data suggest effective containment clade V strains, but subsequently, multiple waves G were circulating widely in Europe.
With numbers of COVID-19 cases having substantially increased at the end 2022 in China, some countries have started or expanded testing and genomic surveillance travellers. We report screening results Italy late December 556 flight passengers provenance from two Chinese provinces. Among these passengers, 126 (22.7%) tested SARS-CoV-2 positive. Whole genome sequencing 61 passengers’ positive samples revealed Omicron variants, notably sub-lineages BA.5.2.48, BF.7.14 BQ.1.1, line with data...
Abstract Whole‐genome sequencing (WGS) has been widely used for the genomic characterization and phylogenesis of mpox virus (MPXV) 2022 multi‐country outbreak. To date, no evidence reported on intra‐host evolution within samples collected over time from a single patient with long‐term infection. Fifty‐one were five patients at different points post‐symptom onset. All confirmed as MPXV DNA positive, amplified by multiplexed PCR amplicon, sequenced WGS. Complete genomes assembled reference...
Our objectives for this study were to understand the biological basis of meat tenderness and provide an overview gene expression profiles related quality as a tool selection. Through deep mRNA sequencing, we analyzed in muscle tissues two Italian cattle breeds: Maremmana Chianina. We uncovered several differentially expressed genes that encode proteins belonging family tripartite motif proteins, which are involved growth, cell differentiation apoptosis, such TRIM45, or play essential role...
The continuous emergence of SARS-CoV-2 variants and subvariants poses significant public health challenges. latest designated subvariant JN.1, with all its descendants, shows more than 30 mutations in the spike gene. JN.1 has raised concerns due to genomic diversity potential enhance transmissibility immune evasion. This study aims analyse molecular characteristics JN.1-related lineages (JN.1*) identified Italy from October 2023 April 2024 evaluate neutralization activity against a subsample...
In January 2015, during a 3-week period, 12 captive Tonkean macacques at sanctuary in Italy died. An orthopoxvirus infection was suspected because of negative-staining electron microscopy results. The diagnosis confirmed by histology, virus isolation, and molecular analysis performed on different organs from all animals. epidemiologic investigation unable to define the source surrounding area. Trapped rodents were negative virologic testing, but specific IgG detected 27.27% small 14.28%...
The Republic of Congo (RoC) declared a chikungunya (CHIK) outbreak on 9 February 2019. We conducted ONE-Human-Animal HEALTH epidemiological, virological and entomological investigation.
