Multi‐country outbreak of Salmonella Enteritidis phage type 8, MLVA profile 2‐9‐7‐3‐2 and 2‐9‐6‐3‐2 infections

Abstract

A multi-country outbreak of Salmonella Enteritidis phage type (PT) 8 with multiple locus variablenumber tandem repeat analysis (MLVA) profiles 2-9-7-3-2 and 2-9-6-3-2, linked to eggs, is ongoing in the EU/EEA. Based on whole genome sequencing (WGS), isolates are part of two distinct but related genetic clusters. ECDC and EFSA are liaising with relevant authorities in the Member States and the European Commission to facilitate the coordination of investigation and response measures. From 1

Infection, colonization and shedding of Campylobacter and Salmonella in animals and their contribution to human disease: A review

“…Animal food products are implicated in human Salmonella infection outbreaks related to local and multinational food distribution networks (Dallman et al, 2016;EFSA & ECDP, 2017;Zenner et al, 2014), and international in-flight catering (Rebolledo et al, 2014). The isolation of Campylobacter strains from chicken carcases similar to those frequently isolated in humans is not uncommon and signifies the importance of animals in human infections (Devane et al, 2013;Nielsen et al, 2006;Stone et al, 2013).…”

Modern Salmonella subtyping methods in outbreak investigations

“…MLVA-профили штаммов меняются достаточно быстро, что позволяет идентифицировать клоны и дифференцировать эпидемические штаммы при расследовании вспышек [8,11,13,16,17]. В странах Евросоюза и США метод MLVA широко используется при расследовании вспышек, в том числе международных, вызванных штаммами двух ведущих серотипов (S.Enteritidis, S.Typhimurium), для субтипирования которых разработаны стандартизированные протоколы [18][19][20][21][22][23][24][25]. По сравнению с PFGE этот метод имеет большую разрешающую способность.…”

Genomic Epidemiology and Multilevel Genome Typing of Australian Salmonella enterica Serovar Enteritidis

“…In many countries (e.g., United States, United Kingdom, Uruguay, Lebanon), S. Enteritidis is ranked as the most common serovar responsible for human infections ( 5 – 8 ). In the past few years, large-scale multinational outbreaks of S. Enteritidis were reported ( 9 – 13 ). From 2017 to 2020, a multistate outbreak of S. Enteritidis in Europe resulted in 656 confirmed cases ( 14 ).…”
