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)
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)

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)
The progressive decline in the hare population across Europe has been associated with the occurrence of European brown hare syndrome (EBHS), a highly contagious disease considered endemic in all European countries. This study aimed to evaluate the in-field temporal dynamics of European brown hare syndrome virus (EBHSV) infection in wild European brown hares(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)
In Italy a national Plan for the surveillance of imported and autochthonous human vector-borne diseases (chikungunya, dengue, Zika virus disease and West Nile virus (WNV) disease) that integrates human and veterinary (animals and vectors) surveillance, is issued and revised annually according with the observed epidemiological changes. Here we describe(More)
From 1 May 2015 to 31 October 2015 over 20 million visitors from all over the world visited the Universal Exhibition (EXPO) hosted by Milan (Lombardy region, Italy), raising concerns about the possible introduction of mosquito-borne diseases from endemic countries. The entomological surveillance protocol performed in Lombardy over the last three years was(More)
BACKGROUND Salmonella spp. have been isolated from a wide range of wild animals. Opportunistic wild carnivores such as red foxes (Vulpes vulpes) and badgers (Meles meles) may act as environmental indicators or as potential sources of salmonellosis in humans. The present study characterizes Salmonella spp. isolated from the intestinal contents of hunted or(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)
