Project description:The gut of chicken is mostly colonised with Campylobacter jejuni and with 100 fold less C. coli. The competitive ability of C. coli OR12 over C. jejuni OR1 has been examined in experimental broiler chickens following the observation that C. coli replaced an established C. jejuni intestinal colonisation within commercial chicken flocks reared outdoors (El-Shibiny, A., Connerton, P.L., Connerton, I.F., 2005. Enumeration and diversity of campylobacters and bacteriophages isolated during the rearing cycles of free-range and organic chickens. Applied Environmental Microbiology. 71, 1259-1266).
Project description:An integrated genomic and proteomic analysis was undertaken to determine the physiological response of Escherichia coli O157:H7 Sakai to steady-state conditions relevant to low temperature and water activity conditions experienced during meat carcase chilling in cold air. The response of E. coli during exponential growth at 25°C aw 0.985, 14°C aw 0.985, 25°C aw 0.967 and, 14°C aw 0.967 was compared to that of a reference culture (35°C aw 0.993).
