Dissertation: Exploring the epidemiology and population structure of Campylobacter jejuni in humans, broilers and wild birds

Submitted by ohsadmin

Petra Griekspoor Berglund defends her PhD thesis entitled Exploring the epidemiology and population structure of Campylobacter jejuni in humans, broilers and wild birds at Linnaeus University in Fullriggaren 28 May at 09:00. Faculty opponent is associate professor Hans Lindmark from the National Food Agency, Uppsala, Sweden.
 
In her work, Petra Griekspoor Berglund has used multilocus sequence typing to analyze genetic population differentiation and gene flow between different populations of C. jejuni isolated from humans, poultry and wild birds. The thesis shows very strong subdivision by hosts in wild bird bacterial population, indicating host specificity for certain C. jejuni lineages. Swedish broiler isolates collected over an eight year period did not show any large changes, and genotype distributions were similar to those observed in other countries. Wild bird campylobacters are rare in human disease, but a small proportion of poultry isolates showed affinity to wild bird strains.
