Goose circovirus (GCV) presents an immunosuppressive problem in production of geese. The infection’s clinical symptoms include growth retardation or feathering disorders but the infection process may remain non-symptomatic what makes the infected birds more susceptible for secondary viral, bacterial and fungal infections. Diagnosis of GCV infection is made(More)
BACKGROUND The identity of herpesviruses isolated in Europe from domestic pigeons (Columbid herpesvirus-1 - CoHV-1) as well as falcons and owls remains unknown. All these herpesviruses are antigenically and genetically related. The falcons and owls are thought to have become infected during the ingestion of pigeon meat thus suggesting the virus's capacity(More)
The aim of the foregoing study was the determination of the occurrence of parvovirus in chicken flocks from different regions of Poland during 2002-2011. The material used for this study originated from chickens showing clinical symptoms of stunting and emaciation. For the quick detection of genetic material of the viruses in field samples, real-time PCR(More)
Duck plague (DP) caused by anatid herpesvirus 1, also called duck enteritis virus (DEV), presents one of the most important concerns in mass waterfowl production. Apart from geese and ducks, free-ranging water birds are the most notorious infection carriers. The epidemiology of DEV in Western Europe remains unknown. Therefore, it was reasonable to conduct a(More)
Herpesviruses of humans and animals cause severe diseases that influence not only the health and epidemiological status but are also economically important in the context of food production. The members of Herpesviridae are host specific agents that also share many properties that potentially make them capable of crossing the species barriers. The objective(More)
AIMS The aim of this study was to investigate the common occurrence of reticuloendotheliosis virus (REV) among Gallid herpesvirus 2 (GaHV-2) infected chickens. The possible cause of this co-occurrence may be linked to contaminated vaccine stocks, which were also examined. METHODS AND RESULTS The study was conducted on 25 field isolates of GaHV-2 collected(More)
In Poland, African swine fever (ASF) emerged in February 2014; by August 2015, the virus had been detected in >130 wild boar and in pigs in 3 backyard holdings. We evaluated ASF spread in Poland during these 18 months. Phylogenetic analysis indicated repeated incursions of genetically distinct ASF viruses of genotype II; the number of cases positively(More)
Marek's disease (MD) remains a serious problem in the production of poultry. The disease is caused by Marek's disease virus (MDV), and despite the ubiquitous use of vaccination to control losses, MD still affects poultry farming worldwide. The aim of this study was to develop a loop-mediated isothermal amplification (LAMP) method for the simple and(More)
BACKGROUND Waterfowl parvoviruses cause serious loss in geese and ducks production. Goose parvovirus (GPV) is infectious for geese and ducks while Muscovy duck parvovirus (MDPV) infects Muscovy ducks only. So far, for these viruses' sensitive detection polymerase chain reaction (PCR) and loop-mediated isothermal amplification (LAMP) were applied. However,(More)
Mycoplasma synoviae (MS) remains a serious concern in production of poultry and affects world production of chickens and turkeys. Loop-mediated isothermal amplification (LAMP) of DNA has been recently used for the identification of different economically important avian pathogens. The aim of this study was to develop LAMP for simple and inexpensive(More)
