Distribution of Salmonella enterica serovars from humans, livestock and meat in Vietnam and the dominance of Salmonella Typhimurium phage type 90.
Many sero- and phage types found in humans were also found in cattle, pigs, and poultry suggesting that food producing animals are an important source of human non-typhoid Salmonella infection in Vietnam. Expand
Antibiotic resistance, integrons and Salmonella genomic island 1 among non-typhoidal Salmonella serovars in The Netherlands.
Investigation of antimicrobial resistance patterns, integron characteristics and gene cassettes as well as the presence of Salmonella genomic island 1 (SGI1) in non-typhoidal Salmonellosis isolates from human and animal origin found the same resistance phenotype, integrons profile and SGI1 structure could be observed.

Evaluation of the Premi Test Salmonella, a commercial low-density DNA microarray system intended for routine identification and typing of Salmonella enterica.
A new commercial system based on genetic profiling and aimed at identifying Salmonella enterica serovars was evaluated by comparing its performance with classical serotyping on 443 strains and showed interesting potential for routine laboratory testing. Expand
Class 1 integrons in Dutch Salmonella enterica serovar Dublin isolates from clinical cases of bovine salmonellosis.
Analysis of plasmid profiles and pulsed field gel electrophoresis (PFGE) patterns showed at least some clonality among the Salmonella Dublin isolates, but 11 different types could be distinguished based on both XbaI and BlnI-PFGE patterns, thus, the Dutch Salmoneella Dublin strains were closely related but not clonal.

Escherichia coli in bacteremia: O-acetylated K1 strains appear to be more virulent than non-O-acetylated K1 strains
A total of 174 blood isolates of Escherichia coli, collected during a 5-year period at the University Hospital Utrecht, were serotyped with rabbit sera against 171 O antigens and 73 capsule (K)Expand
Serotypes of bovine Escherichia coli producing cytotoxic necrotizing factor type 2 (CNF2).
The serotypes of CNF2 NTEC were different from those found in NTEC producing CNF1 and in enterotoxigenic, verotoxigeic, enteropathogenic, enteroinvasive and enteroadherent E. coli strains that cause infections in humans and animals. Expand
Outbreak of Salmonella Bovismorbificans associated with the consumption of uncooked ham products, the Netherlands, 2016 to 2017
This investigation illustrates the importance of laboratory surveillance for all Salmonella serotypes and the usefulness of WGS in an outbreak investigation. Expand
Sources and transmission routes of campylobacteriosis: a combined analysis of genome and exposure data.
Poultry and cattle are the main livestock sources of campylobacteriosis, while pets and surface water are important non-livestock sources, while foodborne transmission is only partially consistent with the attributions. Expand
