| propagation of viruses infecting waterfowl on continuous cell lines of muscovy duck (cairina moschata) origin. | duck circovirus, duck hepatitis a virus 1, goose parvovirus and goose haemorrhagic polyomavirus are economically damaging pathogens of waterfowl, and replicate poorly or not at all in established cell lines. age1.cr, age1.cr.pix and age1.cs cell lines, originating from the muscovy duck, were tested for their suitability to isolate and identify these viruses. immunofluorescence (if) and quantitative polymerase chain reaction investigations verified that all cell lines are permissive for all four ... | 2014 | 24992264 |
| comparative pathogenicity of duck hepatitis a virus-1 isolates in experimentally infected pekin and muscovy ducklings. | duck hepatitis virus (dhv) has always been considered one of the threats endangering duck farming in egypt since the 1960s. in the current study, suspected dhv samples (n = 30) were obtained from commercial pekin, mulard (hybrid), and muscovy duck farms and backyards in beheira, alexandria, gharbia, kafr el-sheikh, and giza provinces between 2012 and 2017. diseased 3-21-day-old ducklings showed a clinical history of high mortality rates and nervous signs. samples were screened by rt-pcr targetin ... | 2020 | 32671102 |
