Quantitative IgG response to SARS-CoV-2 membrane protein in infected individuals strongly correlates with lung injury.

The clinical manifestations of SARS-CoV-2 infection may range from asymptomatic or minor conditions to severe and life-threatening outcomes. The respiratory system is a principal target of the virus and in the majority of cases of severe disease, an acute form of pneumonia develops. Despite concerted global efforts to elucidate the pathogenic mechanisms of COVID-19, the progression of the infection leading to pulmonary damage remains poorly understood.

Pan-yellow fever virus detection and lineage assignment by real-time RT-PCR and amplicon sequencing.

Yellow fever disease is a viral zoonosis that may result in a severe hemorrhagic disease. A safe and effective vaccine used in mass immunization campaigns has allowed control and mitigation against explosive outbreaks in endemic areas. Since the 1960's, re-emergent of the yellow fever virus has been observed.

Durability of neutralizing antibodies against yellow fever virus after vaccination in healthy adults.

In accordance with the World Health Organization, one dose of yellow fever vaccine may guarantee protection lifelong in healthy adults. However, relatively little information is still available from ad hoc studies. We evaluated the persistence of neutralizing antibodies, which are considered to be an immune correlate of protection, in a large number of military personnel vaccinated up to 47 years before.

Analysis of Genomic Characteristics of SARS-CoV-2 in Italy, 29 January to 27 March 2020.

We performed next-generation sequencing (NGS), phylogenetic analysis, gene flows, and - and -glycosylation prediction on SARS-CoV-2 genomes collected from lab-confirmed cases from different Italian regions. To this end, a total of 111 SARS-CoV-2 genomes collected in Italy between 29 January and 27 March 2020 were investigated. The majority of the genomes belonged to lineage B.
