Genomic evidence of environmental and resident Salmonella Senftenberg and Montevideo contamination in the pistachio supply-chain.

Pistachios have been implicated in two salmonellosis outbreaks and multiple recalls in the U.S. This study performed an in-depth retrospective data analysis of Salmonella associated with pistachios as well as a storage study to evaluate the survivability of Salmonella on inoculated inshell pistachios to further understand the genetics and microbiological dynamics of this commodity-pathogen pair.

Complete Genome Sequences of Four Salmonella enterica Strains Associated with Pistachios Assembled Using a Combination of Short- and Long-Read Sequencing.

Here, we report the genomes of two subsp. serovar Montevideo strains (CFSAN005645 and FCC0123) and two subsp. serovar Senftenberg strains (FSW0104 and CFSAN087304) isolated from pistachios.

Complete Genome Sequences of Five Salmonella enterica Strains Used in Inoculation Cocktails in Low-Moisture Food Storage Studies.

Survival kinetics of Salmonella enterica have been previously studied using an inoculum cocktail composed of different strains that have been associated with low-moisture foods. Here, we report the closed genome sequences of five strains of Salmonella enterica that are commonly used in these storage studies.

Closed Genome Sequences of Two Clostridium botulinum Strains Obtained by Nanopore Sequencing.

Here we report the genome sequences of two toxin-producing Clostridium botulinum strains, one environmental sample (83F) and one clinical sample (CDC51232). The genomes were closed by a combination of long-read and short-read sequencing. The strains belong to C.

First Complete Genome Sequence of Salmonella enterica subsp. enterica Serovar Worthington Strain CFSAN051295, Isolated from Pistachio.

We report here, using third-generation, single-molecule, real-time DNA sequencing, the first complete genome sequence of Salmonella enterica serovar Worthington CFSAN051295, isolated from pistachios in the United States. The genome consists of a single 4.9-Mb chromosome.

Complete Genome Sequences of Four Salmonella enterica subsp. enterica Serovar Senftenberg and Montevideo Isolates Associated with a 2016 Multistate Outbreak in the United States.

A multistate outbreak of 11 infections linked to pistachio nuts occurred in 2016. In this announcement, we report the complete genome sequences of four subsp. serovar Senftenberg and subsp.

Asymmetric transfer efficiencies between fomites and fingers: Impact on model parameterization.

Background: Healthcare-associated infections (HAIs) affect millions of patients every year. Pathogen transmission via fomites and healthcare workers (HCWs) contribute to the persistence of HAIs in hospitals. A critical parameter needed to assess risk of environmental transmission is the pathogen transfer efficiency between fomites and fingers.

Nutrition in the management of gastrointestinal diseases and disorders: the evidence for the low FODMAP diet.

A growing interest from both physicians and patients is fueling research in the interaction of symptoms related to irritable bowel syndrome (IBS) and diet, particularly the low FODMAP diet. Recent studies further define the role of these short-chain fermentable carbohydrates on IBS symptoms and their effects in different parts of the gastrointestinal tract. Mounting evidence supports the use of a low FODMAP diet in the clinical setting, but this dietary approach is not without potential drawbacks.

Analysis of the polysaccharide capsule of the systemic pathogen Streptococcus iniae and its implications in virulence.

Systemic pathogens have developed numerous strategies for evading the defenses of the host, permitting dissemination and multiplication in various tissues. One means of survival in the host, particularly in the bloodstream, has been attributed to the ability to avoid phagocytosis via capsular polysaccharide. To further define the virulence capacity of Streptococcus iniae, a zoonotic pathogen with the ability to cause severe systemic disease in both fish and humans, we performed an analysis of the capsule locus.

Large-scale screen highlights the importance of capsule for virulence in the zoonotic pathogen Streptococcus iniae.

Zoonotic pathogens have the unique ability to cross the species barrier, causing disease in both humans and specific animal hosts. Streptococcus iniae is a zoonotic pathogen of both fish and humans, and the clinical presentations of S. iniae infections in fish and humans are very similar to those caused by various human-specific streptococcal pathogens.

Zebrafish as a model host for streptococcal pathogenesis.

Streptococcal pathogens continue to evade concerted efforts to determine clear-cut virulence mechanisms, although numerous genes have been implicated in pathogenesis. A single species can infect a diversity of tissues, suggesting the expression of specific virulence factors based on the local tissue environment or stage of infection. In an effort to identify the interactions that occur between the host and pathogen that lead to activation of virulence mechanisms and contribute to specific streptococcal disease states, we have developed a unique animal model, the zebrafish (Danio rerio), to characterize specific virulence mechanisms utilized within various tissues in vivo.
