Broiler chickens with clinical signs of uneven growth, depression, and dull feathers were submitted to our laboratory and, at necropsy, lesions in proventriculus, gizzard, and intestines were detected. Fowl adenovirus serotype 1 (FAdV-1) was isolated from digestive tissues. The virus, assigned as FAdV-PL/G068/08, showed 99.5% nucleotide homology and 99.2%(More)
Between 2008 and 2011, commercial turkey and chicken flocks in Poland were examined for the presence of turkey parvovirus (TuPV) and chicken parvovirus (ChPV). Clinical samples (10 individual faecal swabs/flock) from 197 turkey flocks (turkeys aged 1 to 19 weeks) and 45 chicken flocks (chickens aged 3 to 17 weeks) were collected in different regions of the(More)
The virulence of pigeon paramyxovirus type 1 (PPMV-1) for different species of birds was investigated in two independent sets of experiments in which groups of pigeons, chickens, turkeys, quails, and geese (10 birds per group) were inoculated with 10(6) median embryo infectious doses of PPMV-1 isolate: 1) nonpassaged (nPPMV-1, intracerebral pathogenicity(More)
The comparison of the conventional (aimed at the UTR’3 fragment) and nested RT-PCR (aimed at the N gene fragment) based methods revealed that nested PCR was about 1000 times more sensitive for the detection of infectious bronchitis virus (IBV). Molecular differentiation of 793/B, D274, and Mass IBV types was also achieved in multiplex nested PCR. Eight from(More)
Avian astroviruses (aAstVs) are divided into three species, Avastrovirus 1, Avastrovirus 2, and Avastrovirus 3, but there are a few strains are waiting to be assigned to an official taxonomic group. This study presents the molecular characterization of chicken astrovirus (CAstV), PL/G059/2014, which is involved in the induction of “white chicks” condition.(More)
Chicken astrovirus (CAstV) was recently indicated as the factor of the "white chicks" condition associated not only with increased embryo/chick mortality but also with weakness and white plumage of hatched chicks. In February 2014, organ samples (livers and kidneys) from dead-in-shell embryos, as well as 1-day-old whitish and normal chicks, were delivered(More)
The presence of turkey astrovirus (TAstV) was monitored in meat-type turkey flocks in Poland in 2008. Clinical samples (10 individual faecal swabs/flock) from 77 flocks aged 1-19 weeks were collected from different regions of the country. RT-PCR experiments were performed for detection and molecular characterization of TAstV using four sets of primers(More)
We examined 884 wild birds mainly from the Anseriformes, Charadriiformes and Galliformes orders for infectious bronchitis (IBV)-like coronavirus in Poland between 2008 and 2011. Coronavirus was detected in 31 (3.5%) of the tested birds, with detection rates of 3.5% in Anseriformes and 2.3% in Charadriiformes and as high as 17.6% in Galliformes. From the 31(More)
Avian astrovirus infections are widespread in many countries, and infections have been connected with enteritis and increased mortality in young birds. In the present study, fecal samples were collected during 2009-2012 from a total of 156 meat turkey flocks. Astrovirus presence and type differentiation was performed with the use of two molecular diagnostic(More)
