| pathobiology of h9n2 avian influenza virus in japanese quail (coturnix coturnix japonica). | clinical signs, serologic response, viral contents of the trachea and intestine, and histopathological and ultrastructural changes of the tracheal epithelium of japanese quail experimentally infected with field isolate of h9n2 avian influenza were studied. vaccinated and unvaccinated quail were inoculated with 10(6.3) 50% embryo infectious dose/bird of a/ chicken/iran/sh-110/99 (h9n2) virus via nasal inoculation. clinical signs such as depression, ruffled feathers, diarrhea, and nasal and eye di ... | 2007 | 17494591 |
| susceptibility and intra-species transmission of the h9n2 g1 prototype lineage virus in japanese quail and turkeys. | avian influenza viruses of the h9n2 subtype have circulated in the poultry population in asia, far and middle east since the mid-1990 s. one of the most widespread lineages established in poultry is the g1 lineage. this lineage has undergone further evolution and reassortment since its first detection in 1997 and g1-like h9n2 viruses still circulate. in this study we have investigated the susceptibility of quail and turkeys to the h9n2 g1-lineage prototype strain (a/quail/hong kong/g1/97). conta ... | 2013 | 23597652 |
| effect of omega-3 rich diet on the response of japanese quails (coturnix coturnix japonica) infected with newcastle disease virus or avian influenza virus h9n2. | this study was performed to evaluate the effects of omega-3 supplementation on growth performance, clinical signs, post-mortem lesions, haemagglutination inhibition (hi) antibody titres, gene expression and histopathology in quails (coturnix coturnix japonica) infected with newcastle disease virus (ndv) and avian influenza virus (aiv) h9n2. one hundred, 40-day-old male quails were divided into 5 groups: g1, fed a control basal diet; g2a, infected with ndv; g2b, infected with h9n2; g3a, infected ... | 2020 | 31712184 |
| study of infection with an iranian field-isolated h9n2 avian influenza virus in vaccinated and unvaccinated japanese quail. | in the present study, we examined the mortality rate, egg production, and clinical signs of quail experimentally infected with a field isolate of a/chicken/iran/339/02 (h9n2) avian influenza virus obtained from an infected commercial layer farm with severe morbidity and mortality. a total of 120 quail at 14 days old were randomly divided into four groups of vaccinated (b and c) and unvaccinated (a and d) birds. vaccination was done on days 20 and 32, and viral inoculation of birds in groups c an ... | 2011 | 21793433 |
