“…Surveillance of S. Enteritidis at poultry facilities was expanded in response to its transition to endemic status. The outbreak has previously been contextualized within global S. Enteritidis lineages ( 11 ). As previously reported ( 4 ), the total NSW S. Enteritidis population was found to consist of 78 unique SNP clusters, including the outbreak-associated cluster, SalEnt-18-0030, containing 197 isolates collected from May 2018 onwards.…”

We examined 5 years of genomic and epidemiological data for the significant global foodborne pathogen, Salmonella enterica . Although Salmonella enterica subspecies enterica serovar Enteritidis ( S. Enteritidis ) is the leading cause of salmonellosis in the USA and Europe, prior to 2018 it was not endemic in the southern states of Australia.

“…Enteritidis typically causes acute gastrointestinal symptoms (nausea, vomiting, fever with diarrhea), like other non-typhoidal Salmonella. However, invasive strains of S. Enteritidis have emerged as a leading cause of bloodstream and other invasive infections globally [23,24]. S. Enteritidis ST11 is one of the most common ST among S. Enteritidis isolates in food, animals, and humans in many countries.…”

Non-typhoidal salmonellosis (NTS) caused by ingesting Salmonella enterica contaminated food or drink remains a major bacterial foodborne disease. Clinical outcomes of NTS range from self-limited gastroenteritis to life-threatening invasive NTS (iNTS). In this study, we isolated Salmonella spp. from the stool and blood of patients hospitalized at Maharaj Nakorn Chiang Mai Hospital, Chiang Mai, Thailand, between 2016–2021 (a total of 395 cases). Then, serovar Typhimurium and Enteritidis were identified and further characterized by multiplex PCR, and multi-locus sequence typing. Our data show that multidrug resistance (MDR) sequence type 34 (ST34) and ST11 are the predominant sequence types for serovars Typhimurium and Enteritidis, respectively. Most S. Typhimurium ST34 lacks spvB, and most S. Enteritidis ST11 harbor sseI, sodCI, rpoS and spvB genes. NTS can be found in a wide range of ages, and anemia could be a significant factor for S. Typhimurium infection (86.3%). Both S. Typhimurium (6.7%) and S. Enteritidis (25.0%) can cause iNTS in immunocompromised patients. S. Typhimurium conferred MDR phenotype higher than S. Enteritidis with multiple antibiotic resistance indexes of 0.22 and 0.04, respectively. Here, we characterized the important S. Typhimurium, S. Enteritidis, and human clinical factors of NTS within the region.

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

Abstract: Salmonella enterica serovar Enteritidis is a leading cause of foodborne infections. We previously developed a genomic typing database (MGTdb) for S. Enteritidis to facilitate global surveillance of this pathogen.
