摘要：

Salmonella enterica subsp. enterica serovar Weltevreden is a dominant serovar associated with foodborne gastroenteritis in South-East Asia and emerging in Europe associated with fresh vegetables. Here we compared the genome of strain 2007-60-3289-1 linked to an alfalfa sprout outbreak in Scandinavia with a S. Weltevreden strain isolated from scallops in the USA and with other S. enterica serovars. A unique plasmid pSW82 was identified for S. Weltevreden carrying a two-component type II non-ribosomal peptide synthase/polyketide synthase. Analysis of all available completes. enterica genomes identified differences for presence of type VI secretion systems and carbohydrate metabolic pathways. Differential transcription thereof was observed when S. Weltevreden strains were grown in vitro or on sprouts. (C) 2012 Elsevier B.V. All rights reserved.
