First report of the invasive mosquito Aedes koreicus (Diptera: Culicidae) and of its establishment in Liguria, northwest Italy.

Background: Invasive mosquito species (IMS) of the genus Aedes are a cause of increasing concern in Europe owing to their ability to vector important human viral diseases. Entomological surveillance to early detect alien mosquito and flavivirus circulation in Liguria, northwest Italy, has been carried out since 2011.

Results: The invasive species Aedes koreicus was first detected in Genoa in September 2015, when a male specimen was caught near the international airport; species identity was confirmed by genetic analysis.

Pseudorabies virus in North-West Italian wild boar (Sus scrofa) populations: prevalence and risk factors to support a territorial risk-based surveillance.

Although  the  eradication  of  Pseudorabies  virus  (PrV)  in  domestic  pigs  is  ongoing,  the circulation  of  this  virus  in  wild  boars  remains  a  threat  in  the  currently  unprotected, 'low prevalence', pig population. In this study, we reported PrV prevalence data and the influence of  possible  risk  factors  in  2  North-West  Italian  wild  boar  populations  (free  and  enclosed) with the goal of supporting the implementation of a risk-based AD surveillance system. Sera from  1,425  wild  boars  were  collected  between  2011  and  2015  and  tested  by  ELISA  for  the presence  of  PrV  antibodies;  the  overall  raw  seroprevalence  was  30.

One after the other: A novel Bluetongue virus strain related to Toggenburg virus detected in the Piedmont region (North-western Italy), extends the panel of novel atypical BTV strains.

In this rapid communication, a novel atypical bluetongue virus (BTV) strain detected in goats in the Piedmont region (north-western Italy) is described. This strain, BTV-Z ITA2017, is most related in Seg-2/VP-2 (83.8% nt/82.

Control of Mosquito-Borne Diseases in Northwestern Italy: Preparedness from One Season to the Next.

Introduction: Mosquito-borne diseases (MBDs) are spreading worldwide due to globalization and climate change, representing a threat for both humans and animals. Of great concern are the infections caused by viruses belonging to the Flavivirus genus as West Nile virus (WNV) and Usutu virus (USUV) transmitted by Culex sp. or Dengue virus and Zika virus (ZIKV), transmitted by Aedes sp.

Detection of West Nile and Usutu Viruses in Italian Free Areas: Entomological Surveillance in Piemonte and Liguria Regions, 2014.

West Nile virus and Usutu virus have established in different parts of Italy over the past 10 years. Piemonte and Liguria Regions (Northwestern Italy) are known to be nonendemic areas, despite the presence of competent vectors and environmental conditions conducive to maintaining infection. This work evidences for the first time, through an entomological surveillance implemented on the basis of risk factor approach, the presence of West Nile and Usutu viruses in Piemonte and Liguria Regions (Northwestern Italy).

Molecular characterization of flaviviruses from field-collected mosquitoes in northwestern Italy, 2011-2012.

Background: The genus Flavivirus comprises several mosquito-borne species, including the zoonotic pathogens West Nile and Usutu virus, circulating in animals and humans in Italy since 1998. Due to its ecological and geographical features, Piedmont is considered a risk area for flavivirus transmission. Here we report the results of a flavivirus survey (detection and genetic characterization) of mosquitoes collected in Piedmont in 2012 and the genetic characterization of three strains detected in 2011.

Food Allergens: State of the Art in Piedmont Region in the Period 2011-2012.

The US National Institutes of Allergy and Infectious Diseases defines food allergy as . Undeclared allergens in food label represent a risk for consumers, as there is no therapy for food allergies. According to Directive 2003/89/EC, declaration of all ingredients and derived substances in the label is mandatory.
