Hepatitis E virus (HEV) is responsible for sporadic acute hepatitis in developed countries, where the infection is acquired probably through ingestion of contaminated food, in addition to travel-related cases. In this study, the circulation of HEV in wild boar from nine Italian provinces was evaluated. An overall seroprevalence of 10.2% was found, although(More)
In the last decade an increase of the number of red foxes in anthropized habitats across European countries, including Italy, has been observed. This pones implications in terms of disease transmission between wildlife and domestic animals; in fact, there are evidences of the role of foxes as reservoirs and amplifiers of a broad spectrum of parasites(More)
We investigate the problem how to lift the non-8 b 1 ()-conservativ-ity of T 2 2 () over S 2 2 () to the expected non-8 b i ()-conservativity of T i+1 2 () over S i+1 2 (), for i > 1. We give a non-trivial reenement of the "lifting method" developed in 4, 8], and we prove a suucient condition on a 8 b 1 (f)-consequence of T2(f) to yield the non-conservation(More)
Mycoplasma hyopneumoniae (Mhyo) is the principal etiological agent of enzootic pneumonia (EP), one of the most economically important diseases in the pig production industry worldwide. Although swine and wild boars (Sus scrofa) share susceptibility to Mhyo infection, information regarding the dynamics of Mhyo infections and pathology in wild boars is(More)
We investigate the possibility to characterize (multi)functions that are b i-deenable with small i (i = 1; 2; 3) in fragments of bounded arithmetic T2 in terms of natural search problems deened over polynomial-time structures. We obtain the following results: 1. A reformulation of known characterizations of (multi)functions that are b 1-and b 2-deenable in(More)
Aujeszky's disease (AD) is one of the most economically important diseases of farmed pigs. Wild boars can act as reservoirs and might represent a potential threat for domestic animals, including dogs. The aim of this study was to report the results of an AD survey based on the Pseudorabies virus (PRV) genome detection in samples of dogs clinically suspected(More)
BACKGROUND Salmonella species (spp.) are zoonotic enteric bacteria able to infect humans, livestock and wildlife.However, little is known about the prevalence and the presence of the different serovars in wildlife. Considering the wide distribution of wild boars and the feeding behaviour (omnivorous scavengers), wild boars may be a good indicator for(More)
West Nile virus (WNV) is a recently re-emerged health problem in Europe. In Italy, an increasing number of outbreaks of West Nile disease, with occurrences of human cases, have been reported since 2008. This is particularly true in northern Italy, where entomological surveillance systems have been implemented at a regional level. The aim of this study was(More)
Mycobacterium microti has recently been described as the causative agent of tuberculosis-like lesions in wild boar (Sus scrofa), a reservoir specie of Mycobacterium tuberculosis complex (MTBC) in some European Mediterranean ecosystem. Through a five-year survey on tuberculosis in free-living wild boars, the epidemiological trend of M. microti infections and(More)
In 2013, the circulation of West Nile virus (WNV) was detected in the Lombardy region and the following year a surveillance programme was activated with the aim of early identification of the viral distribution in mosquitoes and wild birds. A total of 50 959 Culex spp. mosquitoes grouped in six hundred and forty-seven pools as well as 1400 birds were(More)
