The aim of the research was to study impact white striping and wooden breast myopathies on technological quality, mineral, sensory profile poultry meat. With this purpose, a total 138 breasts were selected for control group with normal (N), characterised by (WS) myopathy, having both (WSWB). Data revealed that simultaneous presence two myopathies, respect WS lesion individually considered, had further detrimental effect pH (6.04 vs. 5.96; P < 0.05), yellowness (11.4 10.3; 0.01), cooking...
The purposes of the study were to investigate effects Wooden Breast (WB) myodegeneration on poultry meat quality and give a contribution in typing lesions morphology. At cutting facility, 474 carcasses high-breast-yield hybrid chickens inspected for WB condition, 30 normal (N) affected breast fillets (Pectoralis major) randomly selected. condition represented 53.2% examined carcasses. Weight, cross sectional area (CSA), pH, L*, a*, b* colour values, water-holding capacity, Warner-Bratzler...
Abstract Since their commercialization, vaccines against Porcine circovirus type 2 (PCV2) have been the cornerstone control strategy. Nevertheless, periodic emergence of new genotype waves and recent reports vaccine failure outbreaks raised question if widespread vaccination strategies could driven viral evolution affected different fitness. To investigate this issue an in-deep analysis, based on a bioinformatics biostatistics approach, has implemented. ORF2 sequences from vaccinated...
Infectious bronchitis virus (IBV) represents one of the poultry industry major threats, particularly in high density producing countries. The emergence and spread new IBV genotypes have frustrated various disease control efforts implemented over time. Despite that, few comprehensive large scale studies been performed to understand international local spreading dynamics this virus. In present work, these phenomena were evaluated by implementing a Bayesian phylodynamic approach reconstruct...
Infectious bronchitis is considered to be one of the most devastating diseases in poultry. Control its spread typically attempted through biosecurity measures and extensive vaccination. However, remarkable genetic antigenic variability virus, which originate from both mutations recombination events, represents an unsolved challenge for this disease. The present study reports on emergence recombinant clusters detected Italy Spain between 2012 2014. A total 36 Spanish Italian infectious virus...
Despite the fact that vaccine resistance has been typically considered a rare phenomenon, some episodes of failure have reported with increasing frequency in intensively-raised livestock. Infectious bronchitis virus (IBV) is widespread avian coronavirus, whose control relies mainly on extensive administration. Unfortunately, continuous emergence new vaccine-immunity escaping variants prompts development vaccines. In present work, molecular epidemiology study was performed to evaluate...
The genus Circovirus includes one of the most relevant infectious agents affecting domestic pigs, Porcine circovirus type 2 (PCV-2). wild boar susceptibility to this pathogen has also been demonstrated although actual epidemiological role populations is still debated. In recent times, a new circovirus, 3 (PCV-3), discovered and reported in presence several clinical conditions. However, no information currently available about PCV-3 circulation prevalence boar. To fill gap, 187 serum samples...
Avian metapneumovirus (aMPV) has been identified as an important cause of respiratory and reproductive disease, leading to significant productive losses worldwide. Different subtypes have found circulate in different regions, with aMPV-A B posing a burden especially the Old World, aMPV-C North America, albeit limited exceptions marginal economic relevance. Recently, both aMPV-B reported U.S.; however, route introduction not investigated. In present study, potential importation pathways...
Since the identification of species Porcine circovirus 2, relevance genus Circovirus has increased given its impact on swine industry. A new ( 3, PCV-3) been detected in association with various clinical conditions. Consequently, there is an urgent need for reliable and widely accessible tests both routine diagnostic research purposes. We developed a direct PCR (requiring no DNA extraction) quantitative (q)PCR targeting conserved rep gene to detect PCV-3 genome. Test performance was assessed...
A distinctive infectious bursal disease (IBD) virus genotype (ITA) was detected in IBD-live vaccinated broilers Italy without clinical signs of IBD. It isolated specific-pathogen-free eggs and molecularly characterized the hypervariable region protein (VP) 2. Phylogenetic analysis showed that ITA strains clustered separately from other homologous reference sequences IBDVs, either classical or very virulent, retrieved GenBank previously reported Italy, vaccine strains. The new shows peculiar...
Marek's disease (MD) is an important lymphoproliferative of chickens, caused by Gallid alphaherpesvirus 2 (GaHV-2). Outbreaks are commonly reported in commercial flocks, but also backyard chickens. Whereas the molecular characteristics GaHV-2 strains from poultry sector have been reported, no recent data available for rural sector. To fill this gap, 19 detected Italian chicken flocks during suspected MD outbreaks were molecularly characterized through analysis meq gene, major oncogene. The...
Respiratory diseases like infectious bronchitis virus (IBV) and avian metapneumovirus (aMPV) have been held accountable for major losses poultry production. Nevertheless, scarce information was present dealing with the prevalence molecular epidemiology of these infections in Greece efficacy currently applied control strategies. To fill this gap, a specific epidemiological study designed. A total 106 broiler layer farms, including 10 backyard 96 commercial flocks, were sampled between March...
Avian Metapneumovirus (aMPV) has been recognized as a respiratory pathogen of turkey and chickens for long time. Recently, crescent awareness aMPV, especially subtype B, clinical economic impact risen among European researchers veterinarians. Nevertheless, the knowledge its epidemiology evolution is still limited. In present study, broadest available collection partial G gene sequences obtained from aMPV-B strains was analyzed using different phylodynamic biostatistical approaches to...
The prevention of avian colibacillosis has historically been investigated through vaccination, with variable outcomes. Commercial live (attenuated) and inactivated vaccines are reported to have limited efficacy in the context heterologous challenge. Autogenous using field isolates, is widely used, but scarcely documented. Different vaccination programs, including a commercial vaccine and/or an autogenous vaccine, were compared for three different pathogenic Escherichia coli (APEC) strain...
Bovine coronavirus (BoCV) is an important pathogen of cattle, causing severe enteric disease and playing a role in the bovine respiratory complex. Similar to other coronaviruses, remarkable variability characterizes both its genome biology. Despite their potential relevance, different aspects evolution BoCV remain elusive. The present study reconstructs history using phylodynamic approach based on complete spike protein sequences. results demonstrate high mutation recombination rates...
Colibacillosis is the most common bacterial disease in poultry and it caused by avian pathogenic Escherichia coli (APEC), which assigned to various O-serogroups. Previous studies have shown that APEC strains are more often related certain O-serogroups such asO78, O2 O1. E. has been reported act either as a primary or secondary agent complicating other infections. The aim of this study was investigate occurrence characterize isolated from commercial layer breeder flocks showing macroscopic...
Recent insights into the genetic and antigenic variability of avian metapneumovirus (aMPV), including discovery two new subtypes, have renewed interest in this virus. aMPV causes a well-known respiratory disease poultry. Domestic species show different susceptibility to whereas sporadic detections wild birds revealed links between epidemiology migration routes. To explore species, molecular survey was conducted on samples that were collected from during influenza surveillance activity Italy....
