| pigeon rotavirus a genotype g18p17-associated disease outbreaks after fancy pigeon shows in germany - a case series. | pigeon rotavirus a (rva) isolates of genotype g18p[17] are causing disease outbreaks and fatalities in pigeon lofts in australia, germany, belgium, denmark and usa since 2016. most disease outbreaks have been reported from juvenile pigeons (columba livia forma domestica). however, reports on rva-associated disease outbreaks in fancy pigeons in connection with fancy pigeon shows in germany are rare. | 2021 | 33588462 |
| immunogenicity and protective activity of pigeon circovirus recombinant capsid protein virus-like particles (picv rcap-vlps) in pigeons (columba livia) experimentally infected with picv. | pigeon circovirus (picv) is the most recurrent virus diagnosed in pigeons and is among the major causative agents of young pigeon disease syndrome (ypds). due to the lack of an established laboratory protocol for picv cultivation, development of prophylaxis is hampered. alternatively, virus-like particles (vlps), which closely resemble native viruses but lack the viral genetic material, can be generated using a wide range of expression systems and are shown to have strong immunogenicity. therefo ... | 2021 | 33525416 |
| no detection of sars-cov-2 in animals exposed to infected keepers: results of a covid-19 surveillance program. | sars-cov-2, the causative agent of the covid-19 pandemic, has rarely been associated with transmission from humans to animals (reverse zoonotic transmission). in this retrospective study, the authors reviewed data obtained from 236 animals, including buffaloes, goats/sheep, horses, carrier pigeons, rabbits, hens, snakes, pigs and cows that were screened for sars-cov-2 infection because they had been in contact with their sars-cov-2-positive breeder for at least 2 weeks. none of the tested animal ... | 2021 | 34254029 |
| the first study of west nile virus in feral pigeons (columba livia domestica) using conventional reverse transcriptase pcr in semnan and khorasane-razavi provinces, northeast of iran. | west nile virus (wnv) is an arboviral infection continuing to be as major threat to human health as well as the livestock industry all around the world. birds including pigeons are one of the potential reservoirs for wnv. this study aimed to detect the presence of wnv genome in feral pigeons circulating in semnan and khorasane-razavi provinces (iran) including 10 urban and 10 suburban areas. | 2021 | 34277862 |
| subclinical infection and transmission of clade 2.3.4.4 h5n6 highly pathogenic avian influenza virus in mandarin duck (aix galericulata) and domestic pigeon (columbia livia domestica). | since 2014, h5nx clade 2.3.4.4 highly pathogenic avian influenza viruses (hpaiv) have caused outbreaks in wild birds and poultry in multiple continents, including asia, europe, africa, and north america. wild birds were suspected to be the sources of the local and global spreads of hpaiv. this study evaluated the infectivity, pathogenicity, and transmissibility of clade 2.3.4.4 h5n6 hpaiv in mandarin ducks (aixgalericulata) and domestic pigeons (columbia livia domestica). none of the birds used ... | 2021 | 34199847 |
| in vitro and in vivo characterization of a pigeon paramyxovirus type 1 isolated from domestic pigeons in victoria, australia 2011. | significant mortalities of racing pigeons occurred in australia in late 2011 associated with a pigeon paramyxovirus serotype 1 (ppmv-1) infection. the causative agent, designated apmv-1/pigeon/australia/3/2011 (p/aus/3/11), was isolated from diagnostic specimens in specific pathogen free (spf) embryonated eggs and was identified by a newcastle disease virus (ndv)-specific rt-pcr and haemagglutination inhibition (hi) test using reference polyclonal antiserum specific for ndv. the p/aus/3/11 strai ... | 2021 | 33800329 |
| innate immune responses of domestic pigeons to the infection of pigeon paramyxovirus type 1 virus. | pigeon paramyxovirus type 1 (ppmv-1) is a globally distributed, virulent member of the avian paramyxovirus type-1. the ppmv-1-associated disease poses a great threat to the pigeon industry. the innate immune response is crucial for antiviral infections and revealing the pathogenic mechanisms of ppmv-1. in this study, we evaluated the pathogenicity of a ppmv-1 strain lhlj/110822 in one-month-old domestic pigeons, as well as the host immune responses in ppmv-1-infected pigeons. we observed typical ... | 2020 | 33518113 |
| pigeons as carriers of clinically relevant multidrug-resistant pathogens-a clinical case report and literature review. | pigeons are widespread bird species in urban regions (columba livia forma urbana) and may carry pathogens with zoonotic potential. in recent years, more and more data indicate that these zoonotic pathogens are multidrug resistant. our results confirmed that global trend. three different multidrug-resistant pathogens were isolated from an oral cavity of a racing pigeon with lesions typical for pigeon pox virus infection. staphylococcus aureus was recognized as methicillin resistant, thus resistan ... | 2021 | 34109235 |
