| genotyping of canadian isolates of fowl adenoviruses. | five hundred and seventy-three clinical submissions with fowl adenovirus (fadv) involvement were examined to investigate the association of different types of fadv with clinical problems related to fadv infection. samples were received from 2000 to 2006 and originated from seven canadian provinces. four hundred and eighty-seven submissions were inclusion body hepatitis (ibh) related, while 86 were not ibh related. viruses isolated from 287 samples were further analysed by hexon gene loop 1 seque ... | 2008 | 18202956 |
| flock prevalence of exposure to avian adeno-associated virus, chicken anemia virus, fowl adenovirus, and infectious bursal disease virus among ontario broiler chicken flocks. | samples from 231 randomly selected commercial broiler chicken flocks in ontario were tested at slaughter for exposure to chicken anemia virus (cav), fowl adenovirus (fadv), and infectious bursal disease virus (ibdv). fifteen blood samples per flock were collected and analyzed for the presence of antibodies against cav, fadv, and ibdv by elisa or agar gel immunodiffusion test. fifteen cecal tonsils and cloacal swabs per flock were analyzed for the presence of cav, fadv, and ibdv by pcr. the preva ... | 2014 | 24758116 |
