Plant expression vector's construction of VP2 gene of infectious bursal disease virus

浙江大学学报. 农业与生命科学版, 2003
The VP2 gene of infectious bursal disease virus (IBDV, HZ96 strain) was amplified by polymerase chain reaction with special primers containing Kpn Ⅰ and Sal Ⅰ. The purified PCR product was digested by restricted enzymes Kpn Ⅰ and Sal Ⅰ.

Apoptosis induced by infectious bursal disease virus

Journal of General Virology, 1994
Chicken peripheral blood lymphocytes (PBLs) show morphological and biochemical features of apoptosis (programmed cell death) when infected in vitro with infectious bursal disease virus (IBDV). DNA extracted from IBDV-infected lymphocytes displayed an intense laddering pattern when visualized after agarose gel electrophoresis.

Transcriptomic Analysis of Inbred Chicken Lines Reveals Infectious Bursal Disease Severity Is Associated with Greater Bursal Inflammation In Vivo and More Rapid Induction of Pro-Inflammatory Responses in Primary Bursal Cells Stimulated Ex Vivo

Viruses, 2021
In order to better understand differences in the outcome of infectious bursal disease virus (IBDV) infection, we inoculated a very virulent (vv) strain into White Leghorn chickens of inbred line W that was previously reported to experience over 24% flock

Simultaneous detection of vaccinal and field infectious bursal disease viruses in layer chickens challenged with a very virulent strain after vaccination [PDF]

, 2014
Infectious bursal disease virus is an important poultry pathogen. It is distributed worldwide and causes significant economic losses. In this study, a system was adopted for the simultaneous monitoring of vaccine and virulent strains using reverse ...

Infectious bursal disease virus: identification of the novel genetic group and reassortant viruses

Ветеринария сегодня, 2022
The results of the phylogenic analysis of the nucleotide sequence of the IBDV A and B genome segments have been presented. Traditionally the IBDV isolates are classified based on the phylogenic analysis of the hypervariable region of the VP2 gene.

Biochemistry and Immunology of Infectious Bursal Disease Virus

Journal of General Virology, 1988
Introduction. The aetiological agent of infectious bursal disease (IBD), IBD virus (IBDV), belongs to a new group of viruses referred to as ‘birnaviruses’ (Dobos et al., 1979), which has been characterized only recently (Brown, 1986). There are excellent reviews dealing with the clinical, pathological, serological and epidemiological aspects of IBDV ...

A proposed nomenclature for infectious bursal disease virus isolates [PDF]

Avian Pathology, 2018
Infectious bursal disease virus (IBDV) was initially identified in the USA. For decades, these viruses were not categorized using a typing system because they were considered to be antigenically and pathogenically similar. In the 1980s, a second major serotype, serotype 2, was found in turkeys.
