A Survey For Selected Avian Viral Pathogens In Backyard Chicken Farms In Finland. Avian Pathol. 2016 Sep 13;:1-10 Authors: Pohjola L, Tammiranta N, Ek-Kommonen C, Soveri T, Hänninen ML, Fredriksson-Ahomaa M, Huovilainen A Abstract Backyard poultry is regaining popularity in Europe and increased interest in the health and management of non-commercial farms has resulted. Furthermore, commercial poultry farm owners have become concerned about the risk represented by contagious animal diseases that nearby backyard poultry could transmit. Fifty-one voluntary backyard chicken farms were visited between October 2012 and January 2013. Blood samples and individual cloacal swabs were collected from 457 chickens. In 44 farms (86%), one or more of the tested chickens had antibodies against avian encephalomyelitis and chicken infectious anemia viruses, 24 farms (47%) had chickens seropositive for infectious bronchitis virus, 10 farms (20%) had chickens seropositive for infectious bursal disease virus, six farms (12%) had chickens seropositive for infectious laryngotracheitis virus and two farms (5.4%) had chickens seropositive for avian influenza virus. No farms had chickens seropositive for Newcastle disease virus. Five of the 51 farms (10%) had chickens positive for coronavirus-RT-PCR. Phylogenetic analysis showed that all backyard chicken coronaviruses collected were QX type infectious bronchitis viruses. All chickens tested for avian influen...
