Second-generation Anticoagulant Rodenticides (ARs) can be critical for carnivores, due to their widespread use and impacts. However, although many studies explored the impacts of ARs on small mesocarnivores, none assessed extent which they could contaminate large carnivores in anthropized landscapes. We filled this gap by exploring spatiotemporal trends grey wolf (Canis lupus) exposure central northern Italy, subjecting a sample dead wolves (n = 186) LC-MS/MS method. Most 115/186, 61.8 %)...
Highly pathogenic avian influenza (HPAI) H5N1 viruses are now endemic in many Asian countries, resulting repeated outbreaks poultry and increased cases of human infection. The immediate precursor these HPAI is believed to be A/goose/Guangdong/1/96 (Gs/GD)-like first detected Guangdong, China, 1996. From 2000 onwards, novel reassortant or genotypes have emerged southern China. However, precursors the Gs/GD-like their subsequent reassortants not been fully determined. Here we characterize...
Background: infectious low pathogenic avian influenza viruses (LPaIVs) have been recently detected on feathers of wild ducks. Laboratory trial results suggested that the preen oil gland secretion, covering waterbirds’ feathers, may attract and concentrate virus particles from aIV-contaminated waters to birds’ bodies. We evaluated whether ducks can become infected by ingestion oil-associated viral particles, experimentally smeared their plumage. In addition, we compared virologic serologic...
Abstract Background Avian influenza viruses (AIVs) are endemic in wild birds and their introduction conversion to highly pathogenic avian virus domestic poultry is a cause of serious economic losses as well risk for potential transmission humans. The ability rapidly recognise AIVs biological specimens critical limiting further spread the disease poultry. advent molecular methods such real time polymerase chain reaction has allowed improvement detection currently used laboratories, although...
Abstract Background The wild boar ( Sus scrofa ) and the Apennine wolf Canis lupus italicus are two species that have both increased their presence in Italian territory, albeit varying numbers. They can be occasionally found peri-urban areas as well. Both of these serve intermediate hosts for Toxoplasma gondii , they become infected either through consumption oocysts water, soil, or on vegetables, ingestion meat containing bradyzoites. Consequently, animals regarded key indicators...
Even though dairy cows are known carriers of Arcobacter species and raw or minimally processed foods recognized as the main sources human infections in industrialized countries, data on excretion patterns milk scant. This study aimed to identify potentially pathogenic a herd investigate routes transmission among animals potential cattle infection contamination. A strategy sampling same 50 animals, feed, water, every month for 10-month period, well quarter milk, animal teats, milking...
Over the last 40 years gray wolf (Canis lupus) re-colonized its historical range in Italy increasing human-predator interactions. However, temporal and spatial trends mortality, including direct indirect persecution, were never summarized. This study aims to fill this gap by focusing on situation of Tuscany Emilia-Romagna regions, hosting a significant proportion Italian population, by: (i) identifying prevalent causes (ii) summarizing their patterns (iii) applying spatially-explicit...
The mechanisms of perpetuation influenza A viruses in aquatic birds, their main reservoir nature, have not yet been completely clarified. One hypothesis is that they continue to circulate waterfowl throughout the year, even though virus isolations during winter months are rare. We analyzed circulation wild ducks Italy six seasons (1993-99), using and serological analyses. It was apparent were constantly circulating birds all considered. Moreover, seroconversion rates (obtained from...
Wild aquatic birds in the Orders Anseriformes and Charadriiformes are main reservoir hosts perpetuating genetic pool of all influenza A viruses, including pandemic viruses. High viral loads feces infected permit a fecal-oral route transmission. Numerous studies have reported isolation avian viruses (AIVs) from surface water at bird habitats. These isolations indicate environments an important role transmission AIV among wild birds. However, progressive dilution infectious could decrease...

The increasing involvement of wild waterfowl in H5 Highly Pathogenic Avian Influenza Virus (HPAIV) circulation continues to pose a threat animal and public health worldwide. In winter 2020-2021, two field surveillance activities were carried out on weekly basis, through virological serological analyses, 823 hunted 521 trapped migratory aquatic birds northeast Italy. Sixty Eurasian teals recaptured several times, which allowed us follow the progression HPAI infection naturally infected...
Abstract Background The only natural hosts of Pseudorabies virus (PRV) are members the family Suidae ( Sus scrofa ). In mammals, infection is usually fatal and typically causes serious neurologic disease. This study describes four Aujeszky’s disease cases in free-ranging Italian wolves Canis lupus italicus Italy, wolf a strictly protected species demographic expansion. Case presentation Three (Wolf A, B, C) were found regional park Northern one D) was Central Italy. Wolf A D alive at time...
Avian influenza infections by high and low pathogenicity H7 viruses have caused several outbreaks in European poultry recent years, also resulting human infections. Although some cases the source of strains from domestic was shown to be circulating wild bird reservoir, a thorough characterization entire genome both Eurasian birds, their evolutionary relationships, has not been conducted. In our study, we analysed isolated ducks Italy southern China compared them with those reared terrestrial...
Two epidemics of avian influenza due to H5 and H7 highly pathogenic viruses occurred in poultry Italy 1997/98 1999/2000, respectively. The circulation these serotypes wild aquatic birds was investigated examining 638 cloacal swabs 621 sera collected from 150 gulls, 162 coots, 326 ducks trapped Italian wetlands 1998 2000. Seroprevalences against A viruses, detected by a double-antibody sandwich-blocking enzyme-linked immunosorbent assay (ELISA), were 11% 16% 45% ducks. Among the Anatidae...
Background Wild aquatic birds, reservoir of low-pathogenicity (LP) avian influenza viruses (AIVs), congregate in huge numbers Western Siberia wetlands, where major intra- and inter-continental bird flyways overlap. In 2005 2006, highly pathogenic (HP) AIV H5N1 epizootics affected wild domestic birds the Novosibirsk Region. 2012, we evaluated persistence Siberian natural anthropic ecosystems. Methodology/Principal Findings Region, 166 ecologically linked to environments 152 waterfowl were...
In this study, internal organs (tongue, intestine, and spleen) of 23 free-ranging Italian wolves (Canis lupus italicus) found dead between 2017 2019 were tested for Carnivore protoparvovirus 1, Canine adenovirus (CAdV), circovirus (CanineCV) using real-time PCR assays. Genetic characterisation the identified viruses was carried out by amplification, sequencing, analysis complete viral genome or informative genes. All positive at least one DNA screened, 11/23 coinfected. protoparvoviruses...
