Host-pathogen relationships and the population structure of Campylobacter jejuni in urban wild birds and pets are poorly understood. Using multilocus sequence typing and two cell surface antigens Ms Mohan studied the prevalence and population structure of C. jejuni in ducks, starlings and pets in urban Palmerston North. The ST-45 complex, a clonal complex predominantly reported in human campylobacteriosis cases, was found to be the predominant clone present in all the species investigated. She also analysed the ST-474 C. jejuni genotype, considered to be the endemic strain in New Zealand, by sequencing seven samples of ST-474 and studying a subset of 50 full length genes. These studies provide a better understanding of the evolution and dynamism of C. jejuni as a species.
