Summary: Researchers have developed a chimeric protein-based vaccine targeting seven virulence factors of Shiga toxin-producing Escherichia coli (STEC), which elicited significant immune responses in mice and provided protection against infection. However, further improvement is needed to enhance the vaccine's efficacy and explore other potential mechanisms of protection.

Summary: In a murine model of STEC infection, the stx(2a) phage lytic genes were found to be unnecessary for the virulence of pathogenic O157:H7 clinical isolates or for the release of Stx2a into bacterial cultures. These findings suggest an alternative mechanism for Stx2a release from STEC strains.

Summary: This study investigated the occurrence of STEC in Canadian retail raw ground pork and found the presence of both O157 and non-O157 STEC strains. The virulence gene profiles suggest that non-O157 STEC capable of causing severe human illness are rare in Canadian retail pork, with O157 STEC occasionally occurring. Education regarding the potential risks associated with STEC contamination of pork would be beneficial to help reduce foodborne illnesses.

Summary: Analysis of fecal samples from veal calves slaughtered in France showed that O103:H2 and O26:H11 accounted for 73% of the seven serotypes of Shiga toxin-producing Escherichia coli (STEC), followed by O145:H28 and O157:H7. There were two peaks of higher prevalence during spring and fall, indicating a seasonal variation in STEC carriage. It is necessary to implement interventions in veal calf farming to reduce the risk of STEC contamination in meat production and the food chain.

Summary: The objective of this study was to characterize six colicinogenic Escherichia coli strains and test their inhibitory activity against STEC O157:H7. The results showed that these strains and their colicins have inhibitory activity against STEC O157:H7. PCR and genome sequencing identified various colicins and microcins in these strains, and no genes coding for stx1 and stx2 were detected. The results suggest that colicins could be a potential alternative for reducing the presence of STEC O157:H7.

Summary: After introducing faecal multiplex PCR targeting stx1 and stx2 genes, we detected stx genes in 120 specimens from 111 patients over a 31-month period. The proportion of stx1 only, stx2 only, and co-detection of stx1 and stx2 was 35%, 22%, and 42% respectively. There were 54 culture-positive specimens with 33 different serotypes identified, predominantly O157:H7 (19%). Clinical data available for 82 patients showed high rates of fever (35%), bloody diarrhea (34%), acute kidney injury (27%), hospital admission (80%), and detection of co-pathogens (23%). Only one patient developed haemolytic uraemic syndrome. There was no significant association between stx genotypes and specific symptoms or complications. Serotypes O157:H7 and O26:H11 were significantly associated with bloody stool, but no other symptom or complication showed significant association.

Summary: The foodborne pathogen E. coli O157:H7 poses a serious threat to human life and health. The emergence of bacterial resistance and limitations of traditional food additives have created an unprecedented risk to human food safety. Therefore, there is an urgent need for new food additives that effectively eliminate Shiga toxin producing E. coli (STEC) O157:H7 from food and food processing equipment. Bacteriophage, a highly versatile and safe option in the food chain, has gained renewed attention. This study developed a novel phage cocktail that can effectively remove STEC O157:H7 from liquid food, solid food, and food processing materials simultaneously, without altering the appearance and nutritional content. This study presents a new strategy of utilizing phage cocktail as a food preservative to safeguard human food safety.

Summary: This study examines the pathogenic potential of Shiga toxin-producing Escherichia coli (STEC) O145:H28 in clinical and environmental strains using comparative genomics. The core genes-based tree failed to differentiate between environmental and clinical strains, while the accessory genes-based tree grouped all clinical strains together. Loss-of-function mutations were common in virulence genes related to adherence and secretion systems. Differences in pathogenicity islands and other genetic elements were observed between O145:H28 and reference strains. The study reveals the genetic diversity and evolution of virulence in STEC.

Summary: Extraintestinal pathogenic Escherichia coli (ExPEC) is a major cause of infections in humans and animals globally. In a surveillance study, an E. coli strain from human blood culture was identified with unique characteristics on chromogenic agar and lacking certain biochemical traits. Genomic analysis revealed it to be of sequence type 59 (ST59), belonging to phylogroup F. Further evaluation of ST59 complex showed most strains to have a virulent genotype and unique biochemical behavior, potentially misclassifying them in epidemiological studies relying on typical phenotypes.

The results showed that the different cooking methods did not affect the physicochemical characteristics of the cheese, and sensory evaluation confirmed that the modified production protocol did not significantly alter the product characteristics and overall acceptance. Therefore, cooking under hot water proved to be an effective way to reduce the transformation duration while maintaining the typicality of PDO Pecorino Siciliano cheese.

Summary: In this study, two bacteriophages, PECP14 and PECP20, infecting Escherichia coli O157:H7 were isolated and found to be stable under different environmental conditions. These phages exhibited specificity in targeting different host receptors and demonstrated the ability to infect other foodborne pathogens. The efficacy of phage treatment was demonstrated through rapid adsorption and bacterial lysis. Furthermore, purified endolysins derived from these phages showed remarkable bacteriolytic activity not only against E. coli O157:H7 but also against other pathogens. These findings suggest that these phages and their endolysins can be used for biological control of E. coli O157:H7 in various stages of agricultural product production.

Summary: The effect of multiple sublethal doses of non-thermal plasma treatments on phenotypical changes and the reduction in phytopathogenicity of three species of fungi was investigated. The plasma damaged the surface of the fungal hyphae, decreased their dry biomass, and affected the activity of pectinase and xylanase. Furthermore, the plasma treatments increased the germination rate of artificially infected cucumber seeds and resulted in plants with higher biomass and longer roots and stems. However, the reduction in phytopathogenicity was not complete after the multiple plasma treatments.
