Avian infectious bronchitis virus in Africa: a review [PDF]

open access: yesVeterinary Quarterly, 2016
Infectious bronchitis virus (IBV) is worldwide in distribution, highly infectious, and extremely difficult to control because it has extensive genetic diversity, a short generation time, and a high mutation rate. IBV is a Gammacoronavirus, single-stranded, and positive-sense RNA virus.

The construction of plant expression vector of S1 gene of avian infectious branchitis virus

open access: yes浙江大学学报. 农业与生命科学版, 2001
The S1 gene of avian infectious bronchitis virus (ZJ971 strain) was amplified by polymerase chain reaction with special primers containing XbalI and BamHI. The purified PCR product was digested by the restricted enzyme XbalI and BamHI.

Molecular characterisation of membrane glycoprotein and 5b protein of nephropathogenic infectious bronchitis virus [PDF]

open access: yes, 2013
Background: Infectious bronchitis virus (IBV) affects the upper respiratory tract and the reproductive tract, and some strainscan cause nephritis. Large number of serotypes and genotypes of the virus have been identified and for the most part do notcross-

Ribonucleoprotein of Avian Infectious Bronchitis Virus

open access: yesJournal of General Virology, 1981
The ribonucleoprotein (RNP) of avian infectious bronchitis virus (IBV) was examined by electron microscopy after shadowing with carbon/platinum. Linear RNP strands up to 6.7 microns in length, from three IVB strains, were sensitive to both pancreatic RNase and to proteases. These strands were obtained from spontaneously disrupted complete particles but

Diagnosis of infectious bronchitis: an overview of concepts and tools

open access: yesBrazilian Journal of Poultry Science, 2010
Infectious bronchitis (IB) casues multi-systemic infection in chickens with signs similar caused by other poultry pathogens and thus a high diagnostic accuracy can only be achieved by s series of laboratory assays. This article reviews in a brief way the

Infectious bronchitis vaccine virus detection and part-S1 genetic variation following single or dual inoculation in broiler chicks. [PDF]

open access: yes, 2017
An investigation was undertaken of the extent of genetic variation occurring within infectious bronchitis virus (IBV) vaccine strains following vaccination of day-old broiler chicks. Chicks were divided into seven groups, with two groups receiving single
