<strong>Review</strong> summary<br />
Project OZ0606 focused on <strong>the</strong> dynamics <strong>of</strong> intestinal colonisation <strong>of</strong> chickens with<br />
campylobacter, including <strong>the</strong> effect <strong>of</strong> competitive exclusion and immune responses<br />
during colonisation. This project has demonstrated a clear link between maternal<br />
immunity and <strong>the</strong> colonisation lag phase in chicks, and also identified factors that could<br />
be used in control <strong>of</strong> campylobacter. OZ0606 has also increased knowledge <strong>of</strong> <strong>the</strong> use <strong>of</strong><br />
competitive exclusion products in <strong>the</strong> laboratory environment. The results from this<br />
project showed promise but unfortunately <strong>the</strong> researchers have had difficulty replicating<br />
<strong>the</strong>ir work in <strong>the</strong> subsequent project (OZ0614). This is a difficult research area, however<br />
<strong>the</strong> widespread nature <strong>of</strong> campylobacter, and <strong>the</strong> lack <strong>of</strong> success in controlling this<br />
organism through biosecurity, highlights <strong>the</strong> necessity <strong>of</strong> progressing <strong>the</strong> vaccination<br />
approach.<br />
