EU reference laboratory for Campylobacter - Proficiency test 28 - 2020. EURL-Campylobacter PT28

Proficiency test (PT) number 28 on sequencing of Campylobacter was sent out by the EU reference laboratory (EURL) for Campylobacter in March 2020. The objective of PT 28 was to quantify differences between whole genome sequence (WGS) data from Campylobacter, produced at different laboratories.The strains used in PT-28, one Campylobacter jejuni strain and one Campylobacter coli strain, were isolated from broiler chicken samples collected in the Campylobacter surveillance program in Sweden. The C. jejuni strain was a sequence type (ST)-464 and was isolated in 2016. The C. coli strain was a ST-4709 and was isolated in 2017
