Vaccine-mediated control of shell-less egg syndrome (ses) caused by a variant infectious bronchitis virus (ibv) in Western Canada

Project Details

Status: Active
Investment: $193,000
Commodity: Chicken, Eggs, Multiple Livestock
Organization: University of Calgary
Investigator: Faizal Careem

How will this research impact Alberta’s agriculture industry?

Infectious Bronchitis Virus (IBV) causes an economically important infectious disease in chickens which can be controlled by vaccination. Although IBV is known to cause defective eggs and decreased egg production, in Western Canada, it led to a condition known as Shell-less Egg Syndrome (SES) in vaccinated flocks. This projects will evaluate available live attenuated vaccines and also develop an inactivated vaccine for the control of SES with a view of mitigating SES in Western Canada.

Why did RDAR invest in this project?

Over the last six years, a disease syndrome characterized by a sudden drop in egg production and shell-less eggs has been increasing in the Saskatchewan egg layer industry. Similar outbreaks have also been noted in table egg layer flocks in Alberta and Manitoba.

It is well known that IBV is associated with problems in egg quality and production in poultry and this has caused significant losses for the table egg layer industry in Canada. Infectious Bronchitis (IB) is considered to be primarily a respiratory viral infection, caused by IBV, and is the leading cause of economic loss in poultry globally. The IBV infection is prevalent in commercial chickens in Canada including Alberta. Although vaccination is employed for the control, the existence of large number of serotypes and strains of IBV leads to vaccination failure.

How will research knowledge from this project be transferred and shared with producers?

The outcomes of this project will be communicated to major stakeholders such as Alberta Agriculture and Irrigation, Egg Farmers of Alberta, and Saskatchewan Egg Producers. The project outcomes will also be communicated to poultry producers in a number of ways:

  • Non-scientific publications in magazines, newsletters, and websites such as Canadian Poultry, AB Chicken Producers, and ThePoultrySite.

  • Poster and oral presentations in poultry industry meetings such as poultry innovation conference, Prairies poultry meeting and Western Poultry Diseases Conference.

  • Publication in scientific peer-reviewed journals such as “PLOS One”, “Virology”, “Vaccine”, “Viral Immunology”, “Avian Diseases”, and “Avian Pathology”.
