Induction of IBV strain-specific neutralizing antibodies and broad spectrum protection in layer pullets primed with IBV Massachusetts (Mass) and 793B vaccines prior to injection of inactivated vaccine containing Mass antigen

Avian Pathology, 2019
In an initial study in specified pathogen free (SPF) chickens, a heterologous virus neutralizing (VN) antibody response to IBV variants Q1, Variant 2 (Var 2), D388/QX (D388), D274 and Arkansas (DPI) was observed using a vaccination programme ...

A Recombinant La Sota Vaccine Strain Expressing Multiple Epitopes of Infectious Bronchitis Virus (IBV) Protects Specific Pathogen-Free (SPF) Chickens against IBV and NDV Challenges

Vaccines, 2019
Infectious bronchitis (IB) and Newcastle disease (ND) are two major infectious diseases that are a threat to the domestic poultry industry. In this study, we successfully generated a recombinant LaSota candidate vaccine strain, rNDV-IBV-T/B, which ...

Shaping Up the Tumor Microenvironment With Cellular Fibronectin

Frontiers in Oncology, 2020
Normal tissue homeostasis and architecture restrain tumor growth. Thus, for a tumor to develop and spread, malignant cells must overcome growth-repressive inputs from surrounding tissue and escape immune surveillance mechanisms that curb cancer ...

Think globally, act locally: Phylodynamic reconstruction of infectious bronchitis virus (IBV) QX genotype (GI-19 lineage) reveals different population dynamics and spreading patterns when evaluated on different epidemiological scales

PLoS ONE, 2017
Infectious bronchitis virus (IBV) represents one of the poultry industry major threats, particularly in high density producing countries. The emergence and spread of new IBV genotypes have frustrated the various disease control efforts implemented over ...

Phylogeny of antigenic variants of avian coronavirus IBV

Virology, 1989
The sequences of the peplomeric S1 protein of four serologically distinct strains of the infectious bronchitis virus (IBV), an avian coronavirus, have been determined. The S1 protein is thought to contain the serotype-specific neutralization epitopes and to be the main target of antigenic variation.

Shell-Less Egg Syndrome (SES) Widespread in Western Canadian Layer Operations Is Linked to a Massachusetts (Mass) Type Infectious Bronchitis Virus (IBV) Isolate

Viruses, 2018
A disease with a sudden drop in egg production and shell-less eggs called, shell-less egg syndrome (SES) has been observed in Western Canada egg layer flocks since 2010. The etiology of this disease is not known.

Comparative features of infections of two Massachusetts (Mass) infectious bronchitis virus (IBV) variants isolated from Western Canadian layer flocks

BMC Veterinary Research, 2018
BackgroundInfectious bronchitis virus (IBV) is one of the leading causes of mortality and morbidity in chickens. There are numerous serotypes and variants, which do not confer cross protection resulting in failure of currently used IBV vaccines. Although
