The aims of this study were firstly to evaluate the pathogenicity an Italian isolate QX strain infectious bronchitis (IB) virus using 1-day-old female specific pathogen free chicks (layer type) and commercial broiler type chickens, secondly assess level protection induced in these birds by a vaccination programme including IB Massachusetts 4/91 serotype live attenuated vaccines. Unvaccinated showed clinical signs varying severity, predominantly affecting upper respiratory tract. Vaccinated...
Diet and lifestyle have a strong influence on gut microbiota, which in turn has important implications variety of health-related aspects. Despite great advances the field, it remains unclear to extent composition microbiota is modulated by intake animal derived products, compared vegetable based diet. Here specific impact vegan, vegetarian omnivore dietary choicesfeeding type 101 adults was investigated among groups homogeneous for variables known role modulating microbial such as age,...
Commercial poultry farms (n° 523), located in all the six regions of Nigeria were sampled with a view to generate baseline information about distribution Salmonella serovars this country. Five different matrices (litter, dust, faeces, feed and water) collected from each visited farm. was isolated at least one five 228 farms, farm prevalence 43.6% (CI95[39.7–48.3%]). Altogether, 370 2615 samples (14.1%, CI95[12.8; 15.5%]) contained Salmonella. Considering number positive samples, it evident...
The emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has highlighted the importance having proper tools and models to study pathophysiology emerging infectious diseases test therapeutic protocols, assess changes in viral phenotypes, evaluate effects evolution. This provided a comprehensive characterization Syrian hamster (Mesocricetus auratus) as an animal model for SARS-CoV-2 infection using different approaches (description clinical signs, load, receptor profiling,...
Abstract Viral encephalopathy and retinopathy ( VER ), otherwise known as viral nervous necrosis VNN is a severe pathological condition caused by RNA viruses belonging to the N odaviridae family, genus B etanodavirus . The disease, described in more than 50 fish species worldwide, considered most serious threat affecting marine farmed Mediterranean region, thus representing one of bottlenecks for further development aquaculture industry. To date, four different genotypes have been...
Betanodaviruses are the causative agents of viral nervous necrosis (VNN), a devastating disease for Mediterranean mariculture. Four different betanodavirus species recognized, Striped jack-, Redspotted grouper-, Tiger puffer-, and Barfin flounder virus (SJNNV, RGNNV, TPNNV BFNNV), but there is little knowledge on their antigenic properties. In order to describe serological relationships among genotypes, serum neutralization assays were performed using rabbit polyclonal antisera against eight...
Betanodaviruses are the causative agents of viral nervous necrosis and affect a broad range fish species worldwide. Their bi-segmented genome is composed RNA1 RNA2 molecules encoding polymerase coat protein, respectively. In southern Europe presence RGNNV SJNNV genotypes, RGNNV/SJNNV reassortants has been documented. Several studies have reported correlation between water temperature disease onset. To explore replication efficiency betanodaviruses with different genomes in relation to...
Salmonella is a major cause of food-borne infections in Europe, and the majority human are caused by only few serotypes, among them enterica subsp. serotype Enteritidis (hereafter Enteritidis), Typhimurium, monophasic variant S. Typhimurium. The reason for this not fully understood, but could include virulence factors as well increased ability to transfer via external environment. Formation biofilm considered an adaptation strategy used bacteria overcome environmental stresses. In order...
Molecular methods are widely accepted as gold standard techniques for the laboratory diagnosis of most human and animal pathogens. However, molecular protocols rely on reagents that need to be transported stored at a freezing temperature, requirement might affect their reliability in areas where cold chain cannot guaranteed. Over years, several lyophilized products have been marketed circumvent this issue. We therefore evaluated feasibility replacing liquid with freeze-dried formulations...
Summary This study was conducted to estimate the prevalence of Salmonella spp. and their antimicrobial susceptibilities on poultry swine farms, sampled in 2 regions Central Vietnam. A total 67 farms 46 were a period 5 months (from September 2012 January 2013). prevalent 46.3% 71.7% respectively. Altogether, 99 non‐typhoidal isolated most common serovars Weltevreden (19%), followed by Typhimurium (12%) 4,[5],12:i:‐ (11%). Overall, 71 (72%) isolates resistant at least one 14 agents tested....
Since the 1990s, influenza A viruses of H9N2 subtype have been causing infections in poultry population around globe. This is widely circulating and human cases AI sporadically reported countries where this virus endemic domestic birds. The wide circulation throughout Europe Asia along with their ability to cause direct infection mammals humans, raises public health concerns. was for first time Iran 1998 at present it poultry. study carried out evaluate exposure among workers from Fars...
Since 2006 Egypt has been facing an extensive epidemic of H5N1 highly pathogenic avian influenza (HPAI) with a huge number outbreaks both in rural and intensively reared poultry areas. The use efficacious vaccines this country been, still remains, essential for the control possible eradication HPAI. present study was performed to establish whether administration inactivated containing H5 virus belonging different lineage Eurasian HPAI viruses guarantees protection from clinical signs,...
Eating raw or insufficiently cooked bivalve molluscs contaminated with human noroviruses (NVs) can result in acute cases of gastroenteritis humans. Manila clams (Ruditapes philippinarum) are particularly prone to exposure NVs due the brackish environment which they farmed is known be susceptible faecal contamination. High hydrostatic pressure processing (HHP) a food treatment technique that has been shown inactivate NV.In this study we investigated ability HHP murine norovirus (MNV-1),...
Salmonella is one of the leading food-borne pathogens in Europe and involved several production chains. Understanding most common sources infection important to address valuable control strategies for this pathogen. In present study, a Bayesian model, implemented by EFSA, was used attribute domestic human infections, that occurred Italy over period 2018–2020, four putative food animal sources, namely laying hen eggs, broilers, fattening turkeys pigs addressing national production. The...
Avian influenza (AI) infections have become of growing importance both for animal and human health. Vaccination has a recommended tool to support eradication efforts limit the economic losses caused by this disease. The "DIVA" system, using vaccine containing heterologous neuraminidase field virus, been shown be an effective in increasing resistance birds challenge, preventing clinical signs reducing viral shedding environment. companion diagnostic test vaccine, however, only partially...
Giardia duodenalis (Giardia) is a worldwide cause of acute diarrheal disease both in humans and animals. The primary aim this study was to investigate possible variations gut microbiota population asymptomatic dogs (n = 31), naturally infected or not by Giardia. Gut the hematological, biochemical, fecal parameters related intestinal function were investigated. infection associated with significant shift beta diversity, showing relevant reduction Gammaproteobacteria an increase Fusobacteria...
Salmonella enterica 4,[5],12:i:- is a monophasic variant of S. Typhimurium. In the last decade, its prevalence rose sharply. Although and Typhimurium are known to pose considerable public health risk, there no detailed information on circulation these serovars in Italy, particularly as far veterinary isolates concerned. For this reason, data set 877 strains isolated north-east Italy from foodstuffs, animals environment was analysed during 2005-2010. The Random Forests (RF) method used...
