Antibiotic Resistance Patterns and mcr-1 Detection in Avian Pathogenic Escherichia coli Isolates from Commercial Layer and Layer Breeder Flocks Demonstrating Colibacillosis in Greece
(2021)Objectives: The aim of this study was to investigate the antimicrobial resistance (AMR) patterns of Escherichia coli strains isolated from poultry flocks suffering from colibacillosis in Greece and to detect the presence ... -
Cyanotoxins as the “common suspects” for the Dalmatian pelican (Pelecanus crispus) deaths in a Mediterranean reconstructed reservoir
(2018)Toxic cyanobacterial blooms have been implicated for their negative consequences on many terrestrial and aquatic organisms. Water birds belong to the most common members of the freshwater food chains and are most likely ... -
Detection and molecular characterization of a new genotype of infectious bursal disease virus in Portugal
(2022)Infectious bursal disease virus (IBDV) is an immunosuppressive pathogen with a bi-segmented, double-stranded RNA genome. Two serotypes, named 1 and 2, are recognized, and serotype 1 is traditionally divided into classical, ... -
Evaluation of 793/B-like and Mass-like vaccine strain kinetics in experimental and field conditions by real-Time RT-PCR quantification
(2018)Infectious bronchitis virus (IBV) is a great economic burden both for productive losses and costs of the control strategies. Many different vaccination protocols are applied in the same region and even in consecutive cycles ... -
First Identification and Molecular Characterization of Avian metapneumovirus Subtype B from Chickens in Greece
(2017)Avian metapneumovirus (aMPV) is considered a major pathogen for turkeys but its impact on chicken production is still partially neglected, even though it is fully acknowledged as a primary pathogen in chickens as well. The ... -
Infectious bronchitis virus gel vaccination: evaluation of Mass-like (B-48) and 793/B-like (1/96) vaccine kinetics after combined administration at 1 day of age
(2018)Infectious bronchitis (IB) control has a strong impact on poultry farming, because of the necessary epidemiological knowledge for planning the best strategy, the optimal strain association, the priming and boosting ... -
Molecular epidemiology of fowl adenoviruses in Greece
(2020)Outbreaks of inclusion body hepatitis (IBH) and adenoviral gizzard erosion have been anecdotally reported in Greece since approximately 2011. However, a relevant increase in clinical outbreaks compatible with IBH has been ... -
Molecular epidemiology of infectious bronchitis virus and avian metapneumovirus in Greece
(2019)Respiratory diseases like infectious bronchitis virus (IBV) and avian metapneumovirus (aMPV) have been held accountable for major losses for poultry production. Nevertheless, scarce information was present dealing with the ... -
No good vaccination quality without good control: the positive impact of a hatchery vaccination service program
(2020)Vaccination is currently one of the most relevant control strategies in poultry production to reduce infectious disease–induced economic losses and decrease antimicrobial use. Besides intrinsic vaccine efficacy, a proper ... -
Phylogenetic analysis of bird-virulent West Nile virus strain, Greece
(2019)We report the full polyprotein genomic sequence of a West Nile virus strain isolated from Eurasian magpies dying with neurologic signs in Greece. Our findings demonstrate the local genetic evolution of the West Nile virus ... -
Vaccine or field strains: the jigsaw pattern of infectious bronchitis virus molecular epidemiology in Poland
(2019)Infectious bronchitis (IB), caused by infectious bronchitis virus (IBV), account for severe economic losses in the poultry industry. The continuous emergence of a multitude of IBV variants poses many challenges for its ... -
Viral subpopulation variability in different batches of Infectious bronchitis virus (IBV) vaccines based on GI-23 lineage: Implications for the field
(2022)The control of infectious bronchitis (IB) is largely based on routine vaccine administration, often using live-attenuated vaccines. However, their capability to replicate and be transmitted among animals and farms implies ...
