Interaction between the SifA Virulence Factor and Its Host Target SKIP Is Essential for Salmonella Pathogenesis [Membrane Transport, Structure, Function, and Biogenesis]Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
SifA is a Salmonella effector that is translocated into infected cells by the pathogenicity island 2-encoded type 3 secretion system. SifA is a critical virulence factor. Previous studies demonstrated that, upon translocation, SifA binds the pleckstrin homology motif of the eukaryotic host protein SKIP. In turn, the SifA-SKIP complex regulates the mobilization of the molecular motor kinesin-1 on the bacterial vacuole. SifA exhibits multiple domains containing functional motifs. Here we performed a molecular dissection and a mutational study of SifA to evaluate the relative contribution of the different domains to SifA func...

Why Is Your Turkey Dry?Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
While watching the History Channel, I learned why I haven't made a dry turkey. The secret of my success? Impatience. My family circles the roasting turkey, ready to pounce the instant it hits the minimum cooking temperature, which in my house is 170°F. Depending on what you read, the safe/optimum cooking temperature is 160°F to 180°F. The minimum temperature is supposed to protect you from bacteria (mainly Salmonella) and parasites (eww). If you shoot for the lower temperature then the dark meat of the turkey (the legs and thigh) will be tough and underdone. If you aim at the upper end of the temperature ran...

The path to Crohn's disease: Is mucosal pathology a secondary event?Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Current models of Crohn's disease (CD) invoke an initial disturbance of the epithelial interface between the gut mucosa and intestinal microbiota. This "outside-in" paradigm, mirroring the pathophysiology of acute gastroenteritis, suggests that mucosal damage by luminal bacteria is an early, initiating factor in the etiopathogenesis of disease. However, a number of features of CD argue against a primary mucosal process, including phenotypic studies of CD patients that point to a macrophage defect and genetic studies that predict impaired innate immunity to intracellular bacteria. Intracellular pathogens, such as Listeria, ...

Conclusions: The recent epidemic of S. Enteritidis infection in Uruguay has been driven by the introduction of closely related strains of phage type 4 lineage. Our results confirm previous reports demonstrating a high degree of genetic homogeneity among S. Enteritidis isolates. However, 10 of the regions of variability described here are for the first time reported as being variable in S. Enteritidis. In particular, the oldest pre-epidemic isolates carry phage-associated genetic regions not previously reported in S. Enteritidis. Overall, our results support the view that phages play a crucial role in the generation of gene...

Genome wide evolutionary analyses reveal serotype specific patterns of positive selection in selected Salmonella serotypesEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Background: The bacterium Salmonella enterica includes a diversity of serotypes that cause disease in humans and different animal species. Some Salmonella serotypes show a broad host range, some are host restricted and exclusively associated with one particular host, and some are associated with one particular host species, but able to cause disease in other host species and are thus considered "host adapted". Five Salmonella genome sequences, representing a broad host range serotype (Typhimurium), two host restricted serotypes (Typhi [two genomes] and Paratyphi) and one host adapted serotype (Choleraesuis) were used to id...

Small non-coding RNAs (sRNAs) are an emerging class of post-transcriptional regulators of bacterial gene expression. To study sRNAs and their potential protein interaction partners, it is desirable to purify sRNAs from cells in their native form. Here, we used RNA-based affinity chromatography to purify sRNAs following their expression as aptamer-tagged variants in vivo. To this end, we developed a family of plasmids to express sRNAs with any of three widely used aptamer sequences (MS2, boxB, eIF4A), and systematically tested how the aptamer tagging impacted on intracellular accumulation and target regulation of the Salmon...

A SYBR® Green real-time quantitative polymerase chain reaction (qPCR) assay for specific detection and quantification of airborne Salmonella cells in livestock housings is presented. A set of specific primers was tested and validated for specific detection and quantification of Salmonella-specific invA genes of DNA extracted from bioaerosol samples. Application of the method to poultry house bioaerosol samples showed concentrations ranging from 2.2 x 101 to 3 x 106 Salmonella targets m–3 of air. Salmonella were also detected by a cultivation-based approach in some samples, but concentrations were two to three mag...

Epidemic multiple drug resistant Salmonella Typhimurium causing invasive disease in sub-Saharan Africa have a distinct genotype [LETTERS]Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Whereas most nontyphoidal Salmonella (NTS) are associated with gastroenteritis, there has been a dramatic increase in reports of NTS-associated invasive disease in sub-Saharan Africa. Salmonella enterica serovar Typhimurium isolates are responsible for a significant proportion of the reported invasive NTS in this region. Multilocus sequence analysis of invasive S. Typhimurium from Malawi and Kenya identified a dominant type, designated ST313, which currently is rarely reported outside of Africa. Whole-genome sequencing of a multiple drug resistant (MDR) ST313 NTS isolate, D23580, identified a distinct prophage repertoire a...

Transfer of plasmid-mediated CTX-M-9 from Salmonella enterica Virchow to Enterobacteriaceae in human flora-associated rat (HFA-rat) treated with cefixime.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Food animals are a potential source of CTX-M resistance genes for human pathogens. We evaluated the transfer of the blaCTX-M-9 gene from animal strain of Salmonella enterica Virchow to Enterobacteriaceae of the human intestinal flora, using human flora-associated rats (HFA-rat) with and without cefixime treatment. In the absence of antibiotic, no transconjugant enterobacteria were found in the feces of HFA-rats. However, the transfer rate was high if Escherichia coli J5 recipient strains were co-inoculated orally with Salmonella. S. enterica Virchow persisted in the rat fecal flora, both during and after treatment with...

On the other hand, melioidosis is a newly emerging disease from this region, which is most often misdiagnosed or underdiagnosed by clinicians. It is well accepted that false-positive Widal reactions following certain non-typhoid Salmonella infections may occur commonly. Three cases of high titers...
