Project description:C. jejuni HPC5 is a Campylobacter strain isolated from chickens. Following bacteriophage CP34 treatment on chickens colonised by C. jejuni HPC5, a series of CP34 insensitive strains like C. jejuni HPC5 R14 and C. jejuni HPC5 R20 were obtained which compromised their ability to colonise chickens. Reintroduction of C. jejuni HPC5 R14 and R20 in to chickens led to reversion of these strains and the MRPs of the revertant strains fell in to different classes termed C. jejuni HPC5 R14A, R14B, R20A, R20B and R20C and these strained were tested positive for colonisation proficient and bacteriophage sensitive.
