Shigella Isolates 2019

Wednesday 21st April 2021


Summary

The majority of Shigella isolates were typed using phenotypic methods but four also underwent whole genome sequencing to assist in identification. One of these was then reported as Shigella boydii, one as Shigella species and two as Shigella dysenteriae. 

These Shigella dysenteriae were evaluated in comparison with previous NZ isolates and four isolates from 2018 and 2019 were subsequently confirmed as Shigella dysenteriae serotype E112707/96 ST148. This type has been associated with travel to Central Asia and Africa and typically exhibits increased antimicrobial resistance [Terry et al., Journal of Medical Microbiology DOI 10.1099/jmm.0.000779 Antimicrobial resistance profiles of Shigella dysenteriae isolated from travellers returning to the UK, 2004–2017].
