multiple technological levels the necessity of developing vaccine quality control systems is one of the requirements of our country Coordinated tests of the absence of externous agents in biological substances are considered as a major international concern for veterinary vaccines. Exogenous agents such as Newcastle disease virus, avian leukosis virus, infectious laryngotracheitis virus (ILTV)...
infectious bursal disease (ibd) is a highly contagious disease of chickens caused by the infectious bursal disease virus (ibdv). this study was conducted to characterize three ibdv strains from iran. a reverse transcriptase-polymerase chain reaction (rt-pcr) procedure was used to amplify a 715-bp fragment of the vp1 gene from ibdv strains. amplified vp1 fragments of the three iranian ibdv strai...
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...
Infectious salmon anaemia (ISA) is a severe disease in farmed Atlantic salmon Salmo salar that has caused epidemic outbreaks in most salmon-producing countries worldwide. The disease is caused by virulent ISA virus (ISAV). Low virulent variants of the virus, characterised by a full-length sequence in the highly polymorphic region of segment 6 in the virus genome, have been reported with increas...
Avian influenza virus A/chicken/Jiangsu/1001/2013(H5N2) was identified from a healthy chicken in an eastern China poultry market. Whole-genome analysis demonstrated that the H5N2 virus originated from a reassortance between a previous A/chicken/Hebei/1102/2010(H5N2) virus and an endemic H5N1 virus. The results indicated that continuing reassortance of H5N2 has been occurring in domestic poultry...
BACKGROUND Chicken Mx belongs to the Mx family of interferon-induced dynamin-like GTPases, which in some species possess potent antiviral properties. Conflicting data exist for the antiviral capability of chicken Mx. Reports of anti-influenza activity of alleles encoding an Asn631 polymorphism have not been supported by subsequent studies. The normal cytoplasmic localisation of chicken Mx may i...
