Human Salmonella Isolates, 2019

The number of Salmonella isolates confirmed this year (n=1153) showed an increase in comparison with 2018 (n= 1125). Salmonella Typhimurium phage type 108/170 was the predominant serotype, representing 7.2% of total isolates (0.4% in 2018). Salmonella serotypes showing an increase this year in comparison with 2017 included: S. Enteritidis phage type 8 (from 0.4% to 1.6%), S. Enteritidis phage type 26 (from 0.5% to 1.8%), S. Typhimurium phage type 2 (from 0% to 1.6%) and S. Subsp. (I) ser. 4,5,12 : i : - (from 2.3% to 4.2%)
In the last week of October phage typing was phased out, Whole Genome Sequencing (WGS) was introduced, and from that, point on a Multi Locus Sequence Type (MLST) will be reported as a Sequence Type (ST) number instead for Serotypes Enteritidis, Typhi, and Typhimurium. Multi Locus Sequence Type (MLST or ST) is instead now included in line with standard international practice.
