Experimental Study on the Pathogenicity of Avian Influenza A/Ch/It/5093/99(H7N1) Virus in Chicken

In this study, the pathogenicity of A/Ch/It/5093/1999 H7N1 which had been isolated from chicken during the outbreak in Italy was assessed in chicken by experimental infection virus. Ten SPF chickens of four week-old were inoculated with this virus, and five chickens were inoculated with uninfected allantoic fluid. For determination of virus shedding, oropharyngeal and cloacal swabs were taken f...

A Study on Histopathologic Changes in Chicken Following Intravenous Inoculation with Avian Influenza Virus A/Chicken/Iran/259/1998(H9N2)

Evaluation of the Pathogenicity of A/Chicken/Iran/ZMT-173/99 H9N2 Strain of Avian Influenza Virus in Serologically Mycoplasma Galisepticum Positive and Negative Broiler Chickens

Thermal inactivation of H5N1 high pathogenicity avian influenza virus in naturally infected chicken meat.

Thermal inactivation of the H5N1 high pathogenicity avian influenza (HPAI) virus strain A/chicken/Korea/ES/2003 (Korea/03) was quantitatively measured in thigh and breast meat harvested from infected chickens. The Korea/03 titers were recorded as the mean embryo infectious dose (EID50) and were 10(8.0) EID50/g in uncooked thigh samples and 10(7.5) EID50/g in uncooked breast samples. Survival cu...

Experimental 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 ...

A model for emergence of high pathogenicity avian influenza virus from outbreaks with low pathogenicity avian influenza virus

In this article, we establish a mathematical model for emergence of high pathogenicity avian influenza (HPAI) viruses from outbreaks of low pathogenicity avian influenza (LPAI) A viruses (H5N2). The model is based on traditional mathematical epidemiology models and experiment evidences. It contains several submodels which are traditional SEIR models or SIR models. The experiments in [25] provid...
