Myopia development in humans depends on a complex interplay between genetic and environmental factors. Many of those who become myopic when exposed to a myopigenic environment are likely to do so because of a genetic susceptibility, whereas others somehow remain immune. In the most intensively studied model of environmentally induced myopia, form-deprivation myopia in the chick, there is convin...
In this study, seroprevalence of avian reovirus (ARV) infections in broiler and broiler breeder chicken farms in Aydin, İzmir and Manisa provinces were investigated. Serum samples (n = 631) collected from 8 broiler breeder and 18 broiler flocks were tested for ARV antibodies using a commercially available ARV Enzyme Linked Immunosorbent Assay (ELISA) kit. The sampled flocks were not vaccinated ...
OBJECTIVES This study investigated the prevalence of vancomycin-resistant enterococci (VRE) in the broiler production environment after the avoparcin ban and their epidemiological relationship with human clinical VRE from the same geographical regions in Greece. METHODS Caecal contents from broilers (n = 500) from eight livestock farms and faecal samples from poultry slaughterers (n = 50), al...
The study aims to identify phylogenetic groups and antibiotic susceptibility of poultry Escherichia coli (APEC) isolates. E. was phenotypically biochemically characterized. Isolates from 8/30 (26.66%) liver, 7/30 (23.33%) heart, 4/30 (13.33%) spleen 37-42 days old vaccinated broiler chickens were assessed. Then the isolates (19/90; 21.11%) phylogrouped by quadruplex genotyping based on presence...
