Detection of infectious bronchitis virus in experimentally infected chickens by an antigen-competitive ELISA
(2001-02-07)
An antigen-competitive enzyme-linked immunosorbent assay (Ag-C-ELISA) was developed for the detection of infectious bronchitis virus (IBV) antigens, M41 strain, in tissues from experimentally infected chickens, or in ...
Evaluation of an indirect ELISA method for the detection of chicken antibodies against infectious bronchitis virus
(1996-01-01)
An indirect ELISA method was developed and applied to detect antibodies against infectious bronchitis virus (IBV). Three hundred serum samples collected from vaccinated and non-vaccinated chickens under field conditions ...
First evidence of the emergence of novel putative infectious bronchitis virus genotypes in Cuba
(ELSEVIER SCI LTDOXFORD, 2012)
The emergence of new infectious bronchitis virus (IBV) genotypes or serotypes along with the poor cross-protection observed among IBV serotypes have complicated the avian infectious bronchitis (IB) control programs in ...
A liquid phase blocking ELISA for the detection of antibodies against infectious bronchitis virus
(Associação Brasileira de Divulgação Científica (ABRADIC), 1999-06-01)
A liquid phase blocking ELISA (LPB-ELISA) was developed for the detection and measurement of antibodies against infectious bronchitis virus (IBV). The purified and nonpurified virus used as antigen, the capture and detector ...
Avian infectious bronchitis: viral persistence in the harderian gland and histological changes after eyedrop vaccination
(American Association of Avian Pathologists, 1996)
The histological changes in the harderian gland (HG) induced by the attenuated H-120 infectious bronchitis virus (IBV) vaccine strain and the persistence of this virus in the stroma of the gland was evaluated in chickens ...
Gonadal pathogenicity of an infectious bronchitis virus strain from the Massachusetts genotype
(2019-01-23)
An outbreak of infectious bronchitis caused by the IBVPR03 strain of the Massachusetts genotype affected H-120 vaccinated laying hens in South Brazil. We investigated the cross protection of the vaccine by assessing the ...
Rapid detection and differentiation of avian infectious bronchitis virus: an application of Mass genotype by melting temperature analysis in RT-qPCR using SYBR Green I
(Japan Soc Vet Sci, 2018-04-01)
A method based on Melting Temperature analysis of Hypervariable regions (HVR) of S1 gene within a RT-qPCR was developed to detect different genotypes of avian infectious bronchitis virus (IBV) and identify the Mass genotype. ...
Increased expression of Interleukin-6 related to nephritis in chickens challenged with an Avian infectious bronchitis virus variant
(2015-01-01)
A Brazilian field isolate (IBV/Brazil/PR05) of avian infectious bronchitis virus (IBV), associated with development of nephritis in chickens, was previously genotyped as IBV variant after S1 gene sequencing. The aim of ...
Relationship between mucosal antibodies and immunity against avian infectious bronchitis virus
(2014-01-01)
Immunity against avian infectious bronchitis virus (IBV) was assessed in specific pathogen free (SPF) chickens vaccinated at age of three weeks with H120 attenuated vaccine strain and, after three weeks, by measuring the ...
Analysis of similarity of the SI gene in infectious bronchitis virus (IBV) isolates in Shanghai, China
(Facultad de Ciencias Veterinarias, Universidad Austral de Chile, 2007)
