Highly Pathogenic Fowlpox Virus in Cutaneously Infected Chickens, China
نویسندگان
چکیده
We investigated an acute outbreak of the cutaneous form of fowlpox among chickens in China in November 2009. Using pathologic and virologic methods, we identified a novel type of fowlpox virus that carried an integrated genomic sequence of reticuloendotheliosis virus. This highly pathogenic virus could lead to severe ecologic effects and economic losses.

Subclinical Highly Pathogenic Avian Influenza Virus Infection among Vaccinated Chickens, China
Subclinical infection of vaccinated chickens with a highly pathogenic avian influenza A(H5N2) virus was identified through routine surveillance in China. Investigation suggested that the virus has evolved into multiple genotypes. To better control transmission of the virus, we recommend a strengthened program of education, biosecurity, rapid diagnostics, surveillance, and elimination of infecte...
متن کاملPathological lesions observed in chickens pre-infected with LP H7N1 A/CK/Italy/1279/99 avian influenza and challenged with homologous HP H7N1 A/ostrich/Italy/984/00
Most highly pathogenic avian influenza viruses (AIV) emerge after field passage of non-pathogenic AIVs in birds. The outbreak of low-pathogenic H7N1 avian influenza virus in Italy during 1999-2000 followed by outbreak of highly pathogenic H7N1 avian influenza virus is one example in this regard. This experiment has been designed to investigate the effect of pre-infection of birds with LPAI on s...
متن کاملAvian influenza vaccination: the experience in China.
Highly pathogenic H5N1 avian influenza virus was first detected in the People's Republic of China (China) in 1996 and has caused over 100 outbreaks of disease in poultry since 2004. The Chinese Government has pursued a vaccination strategy to control avian influenza infection in poultry. A series of vaccines including whole-virus inactivated vaccine, recombinant fowlpox vaccine and recombinant ...
متن کاملExperimental study to determine if low-pathogenicity and high-pathogenicity avian influenza viruses can be present in chicken breast and thigh meat following intranasal virus inoculation.
Two low-pathogenicity (LP) and two high-pathogenicity (HP) avian influenza (AI) viruses were inoculated into chickens by the intranasal route to determine the presence of the AI virus in breast and thigh meat as well as any potential role that meat could fill as a transmission vehicle. The LPAI viruses caused localized virus infections in respiratory and gastrointestinal (GI) tracts. Virus was ...
متن کاملImprovements to the hemagglutination inhibition test for serological assessment of recombinant fowlpox-H5-avian-influenza vaccination in chickens and its use along with an agar gel immunodiffusion test for differentiating infected from noninfected vaccinated animals.
In general, avian influenza (AI) vaccines protect chickens from morbidity and mortality and reduce, but do not completely prevent, replication of wild AI viruses in the respiratory and intestinal tracts of vaccinated chickens. Therefore, surveillance programs based on serological testing must be developed to differentiate vaccinated flocks infected with wild strains of AI virus from noninfected...
