Pandemic influenza A/H1N1 virus in a swine farm house in Sicily, Italy.

2012

This report describes a pandemic A/H1N1 (H1N1 pdm) virus outbreak occurred in December, 2009 in a swine farm used as research facility (Istituto Mediterraneo Trapianti e Terapie ad Alta Specializzazione) for preclinical studies, located in Sicily, Italy. All the 13 pigs of the farm, showed cough, fever, inappetence and weakness. At the same time, an unvaccinated worker of the stabling showed influenza-like symptoms. RNAv extracted from two swabs collected from infected pigs resulted positive by Real Time RT-PCR for Influenza A virus. Furthermore, after growth on embryonated eggs, viral isolates were identified by Real Time RT-PCR specific for H1N1 pdm virus and characterized antigenically. …

Local adaptation, coadaptation, and population boundaries

1986

Coadaptation can occur either because of local adaptation in a geographically widespread population and/or because of intrinsic adaptation to the state of other genes or chomosomes. In either event, hybridization between animals with differently coadapted gene or chromosomal complexes can result in a decrease in fertility, viability, etc. in the initial hybrids and especially in later generations. This is known as an outbreeding depression. Moreover, releasing animals not adapted to the local environment can seriously hamper the effectiveness of a reintroduction program, and hybridization can also destroy the local adaptation. Coadapted gene complexes are best detected through studies on na…

Google Searches for Taste and Smell Loss Anticipate Covid-19 Epidemiology

2020

AbstractBackgroundAs evidence emerged that loss of taste and/or loss of smell is frequently triggered by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, we investigated whether Google searches volume for these two disease-specific symptoms could be associated with disease epidemiology in United States (US).Materials and MethodsWe performed an electronic search in Google Trends using the keywords “taste loss” and “smell loss” within the US. The Google searches volume was correlated with the number of new weekly cases of coronavirus disease 2019 (COVID-19) in the country.ResultsThe weekly Google searches for taste and smell loss exhibited a trend similar to that of new…

Phytochemical composition, anti-inflammatory and antitumour activities of four Teucrium essential oils from Greece

2009

Abstract The essential oils of four Teucrium species were studied and 150 components, in all, were identified. All oils were rich in sesquiterpenes (50.1–55.8%). Spathulenol and δ-cadinene were the main compounds of Teucrium brevifolium oil; caryophyllene and 4-vinyl guaiacol predominated in Teucrium flavum . Carvacrol and caryophyllene oxide predominated in Teucrium montbretii ssp. heliotropiifolium , while carvacrol and caryophyllene were the most abundant components in Teucrium polium ssp. capitatum . The oil which most effectively inhibited LPS-induced NO production in macrophage cell line RAW 264.7 was that from T. brevifolium (IC 50  = 7.1 μg/ml), followed by T. montbretii ssp. heliot…

Genomic Analysis of Bacterial Outbreaks

2016

The study of outbreaks of infectious diseases has been revolutionized by the current availability of fast and efficient, high-throughput methods capable of yielding the nucleotide sequence of complete genomes of viruses and bacteria within a few days, or even hours. These methods are replacing previous molecular techniques which have been used for the past 30 years, although many of them are still the usual approach for many such investigations. Here we review the major technologies currently in use for high-throughput sequencing of bacterial genomes emphasizing their advantages and drawbacks for the analysis of outbreaks. The use of more efficient methods does not necessarily mean that all…

New Coronavirus (SARS-CoV-2) Crossing Borders Beyond Cities, Nations, and Continents: Impact of International Travel

2021

The third outbreak of coronavirus in the form of the COVID-19 infection started in Wuhan, China, in December 2019. The early and rapid spread of this infection across borders can be largely attributed to international air travel that has become a part of modern globalization. In this article, we analyze the spread of the novel coronavirus (SARS-CoV-2) along the routes of international travel, both by air and by sea. Pitfalls of various screening methods used at the airports and the importance of optimal aircraft ventilation are discussed. Also, we suggest measures that can be taken to reduce the risk of transmission associated with air travel.

COVID-19 and orientations towards solidarity: the cases of Spain, Hungary, and Romania

2020

Solidarity is core to Europe's societal organisation and was intensively addressed in recent research. Using data collected before and during the lockdown in spring 2020, we examine whether value o...

Media constructions of fear in the outbreak of an epidemic disease

2016

Purpose – After almost a decade, the re-appearance of dengue fever in Argentina caused panic and fears. Unlike Bolivia, Brazil and Paraguay, where prevention policies have been followed, the future of dengue is uncertain in Argentina; the present paper does not have political affiliation but the purpose of this paper is to emphasizes the role that mass media plays in the coverage of epidemics. Design/methodology/approach – In moments of disorder, uncertainness or disaster, societies experience a shift in the ways they perceive their reality. Findings – In the times, media plays a dominant role in constructing the reality that the authors get to consume. Such reality is reflective of media’…

Thrombotic complications of vaccination against SARS-CoV-2: what pharmacovigilance reports tell us – and what they don't

2021

In the present issue of the Journal [1], Smadja et al. present an analysis of global pharmacovigilance reports of thrombotic events following severe acute respiratory distress syndrome coronavirus (SARS-CoV)-2 vaccination. More specifically, the authors analysed the data entered into the World Health Organization (WHO) Global Database for Individual Case Safety Reports (VigiBase) between December 13, 2020 and March 16, 2021, covering, at that time, a population of almost 362 million vaccinated individuals across the world. The study focuses on three of the coronavirus disease (COVID)-19 vaccines available to date, namely the Pfizer-BioNtech (BNT162b2), Moderna (mRNA-1273), and OxfordAstraZe…
