USPOULTRY and the USPOULTRY Foundation announce the completion of a funded research project at the University of Delaware in Newark, Del., in which researchers found that European infectious bronchitis vaccine does not protect against U.S. strains. The research is part of the Association’s comprehensive research program encompassing all phases of poultry and egg production and processing. A brief summary of the completed project is shown below. A complete report may be obtained by going to USPOULTRY’s website, www.uspoultry.org. The project summary is as follows.

Dr. Jack Gelb and colleagues recently completed a research project in which they examined the use of multiple strains of infectious bronchitis vaccines to induce protection against new infectious bronchitis variants. They found that combinations of existing vaccines did not provide protection to the new strains. Inclusion of the European 4/91 vaccine also failed to provide significant protection against current variant strains of infectious bronchitis.
