| tissue tropism of a thailand strain of high-pathogenicity avian influenza virus (h5n1) in tissues of naturally infected native chickens (gallus gallus), japanese quail (coturnix coturnix japonica) and ducks (anas spp.). | the tropism of a thailand strain of highly pathogenic avian influenza h5n1 virus was demonstrated on tissues (lung, trachea, heart, liver, spleen, pancreas, rectum, kidney, brain, skeletal muscle, duodenum, and oviduct) from naturally infected native chickens (gallus gallus), japanese quail (coturnix coturnix japonica) and ducks (anas spp.) by indirect immunofluorescence assay. in chickens and quail, the distribution and localization of nucleoprotein viral antigen was similar and detected at the ... | 2006 | 16753617 |
| isolation of avian influenza virus a subtype h5n1 from internal contents (albumen and allantoic fluid) of japanese quail (coturnix coturnix japonica) eggs and oviduct during a natural outbreak. | avian influenza virus (aiv) was recovered from the internal contents of eggs, including mixture of albumen and allantoic fluid, and from the oviduct of naturally infected japanese quail (coturnix coturnix japonica) flocks in the southern part of thailand. the virus titers of 10(4.6)-10(6.2) eld(50)/ml were directly measured from the internal content of infected eggs. the virus was isolated by chorioallantoic sac inoculation of embryonating chicken eggs. infected allantoic fluid was identified as ... | 2006 | 17135508 |
| pathobiology and transmission of highly and low pathogenic avian influenza viruses in european quail (coturnix c. coturnix). | european quail (coturnix c. coturnix) may share with japanese quail (coturnix c. japonica) its potential as an intermediate host and reservoir of avian influenza viruses (aiv). to elucidate this question, european quail were experimentally challenged with two highly pathogenic aiv (hpaiv) (h7n1/hp and h5n1/hp) and one low pathogenic aiv (lpaiv) (h7n2/lp). contact animals were also used to assess the viral transmission among birds. severe neurological signs and mortality rates of 67% (h7n1/hp) an ... | 2013 | 23537387 |
| pathogenicity in quails and mice of h5n1 highly pathogenic avian influenza viruses isolated from ducks. | in our study, the pathogenicity of h5n1 influenza a viruses circulating in waterfowls in southern china was investigated. three h5n1 highly pathogenic avian influenza (hpai) viruses isolated from ducks, a/duck/guangdong/383/2008(dk383), a/duck/guangdong/378/2008(dk378) and a/duck/guangdong/212/2004(dk212) were inoculated at 10(6) fifty-percent egg infectious doses (eid(50)) into ducks, quails and mice and showed varying levels of pathogenicity. in ducks, the mortality rates ranged from 0 to 60% ... | 2011 | 21665388 |
| the quail genome: insights into social behaviour, seasonal biology and infectious disease response. | the japanese quail (coturnix japonica) is a popular domestic poultry species and an increasingly significant model species in avian developmental, behavioural and disease research. | 2020 | 32050986 |
