The central metabolism regulator EIIAGlc switches Salmonella from growth arrest to acute virulence through activation of virulence factor secretion [PDF]

, 2014
The ability of Salmonella to cause disease depends on metabolic activities and virulence factors. Here, we show that a key metabolic protein, EIIAGlc, is absolutely essential for acute infection, but not for Salmonella survival, in a mouse typhoid fever ...

The Metabolic Pathway of Bile Secretion Is Vulnerable to Salmonella enterica Exposure in Porcine Intestinal Epithelial Cells

Animals
Pigs can be colonized with Salmonella enterica and become established carriers. However, the mechanisms of the host’s response to Salmonella enterica infection are largely unclear.

Salmonella enterica serovars co‐exist sporadically and at low abundance in US mid‐Atlantic irrigation ponds

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Spring or rain‐fed ponds are frequent features on US mid‐Atlantic farms. The need to conduct preharvest agricultural water assessments to identify microbial hazards, as required by the US Produce Safety Rule, highlights knowledge gaps pertaining to pond water adequacy for vegetable production.

Characterization of multidrug-resistant Salmonella enterica serovars Indiana and Enteritidis from chickens in Eastern China.

PLoS ONE, 2014
A total of 310 Salmonella isolates were isolated from 6 broiler farms in Eastern China, serotyped according to the Kauffmann-White classification. All isolates were examined for susceptibility to 17 commonly used antimicrobial agents, representative ...

Rapid and quantitative phage susceptibility test by ramanome

mLife, EarlyView.
Abstract Antimicrobial resistance poses an escalating global threat, renewing interest in bacteriophage therapy as a precision alternative to antibiotics. However, clinical translation remains hindered by the lack of rapid and quantitative phage susceptibility testing (PST) platforms capable of evaluating host range, infection potency, and effective ...

Proteomic Changes in Cancer Cell Lines as a Result of Bacterial Infection

PROTEOMICS, EarlyView.
ABSTRACT Bacterial infections have been implicated in shaping the tumor microenvironment (TME), but their effects on cancer cell proteomes remain unexplored. In this study, we analyzed proteomic changes in melanoma (A375) and ovarian cancer (OVCAR3) cell line models following infection with Staphylococcus aureus strain USA300 or Salmonella enterica ...

Amino acid vectorization of salicylic acid enables efficient activation of NPR1‐dependent defense without phytotoxicity

Pest Management Science, EarlyView.
Amino acid‐vectorized salicylic acid activates PR1/NPR1‐dependent defenses without phytotoxicity, showing an efficient strategy for controlled delivery and enhanced plant immunity. Abstract BACKGROUND Addressing global food security under rapid population growth and climate change requires sustainable strategies to protect crops from pathogens while ...

How the structure of the large subunit controls function in an oxygen-tolerant [NiFe]-hydrogenase [PDF]

, 2014
Salmonella enterica is an opportunistic pathogen that produces a [NiFe]-hydrogenase under aerobic conditions. In the present study, genetic engineering approaches were used to facilitate isolation of this enzyme, termed Hyd-5.
