NBC San Diego

Four more people have reported being sickened by an E. coli outbreak linked to Miguel’s Cocina in the 4S Ranch community of San Diego within the past two days, bringing the total to 17 cases, county health officials said Thursday.

Seven people had to be hospitalized, including four children, according to the county’s Health and Human Services Agency.

“The joint public health and environmental health investigation is ongoing,” HHSA spokesperson Fernanda Lopez said.

Those who fell ill, or their families, reported eating at Miguel’s 4S Ranch location from Oct. 6 to Oct. 18 and developed symptoms from Oct. 13 to Oct. 19, according to the HHSA.

County health officials are still investigating the specific food items that were the source of the Shiga-toxin-producing E. coli (STEC) at the restaurant. Miguel’s voluntarily closed its doors on Tuesday and has been working closely with the County to identify the outbreak.

Research – Haemolytic uraemic syndrome in children England, Wales, Northern Ireland, and Ireland: A prospective cohort study

Posted on October 29, 2023 by | Leave a comment

Cambridge Org

Abstract

Haemolytic uraemic syndrome (HUS) caused by infection with Shiga toxin-producing Escherichia coli (STEC) is a relatively rare but potentially fatal multisystem syndrome clinically characterised by acute kidney injury. This study aimed to provide robust estimates of paediatric HUS incidence in England, Wales, Northern Ireland, and the Republic of Ireland by using data linkage and case reconciliation with existing surveillance systems, and to describe the characteristics of the condition. Between 2011 and 2014, 288 HUS patients were included in the study, of which 256 (89.5%) were diagnosed as typical HUS. The crude incidence of paediatric typical HUS was 0.78 per 100,000 person-years, although this varied by country, age, gender, and ethnicity. The majority of typical HUS cases were 1 to 4 years old (53.7%) and female (54.0%). Clinical symptoms included diarrhoea (96.5%) and/or bloody diarrhoea (71.9%), abdominal pain (68.4%), and fever (41.4%). Where STEC was isolated (59.3%), 92.8% of strains were STEC O157 and 7.2% were STEC O26. Comparison of the HUS case ascertainment to existing STEC surveillance data indicated an additional 166 HUS cases were captured during this study, highlighting the limitations of the current surveillance system for STEC for monitoring the clinical burden of STEC and capturing HUS cases.

Research – Role of Bacillus cereus biofilm formation behavior in virulence and pathogenic characteristics

Posted on October 29, 2023 by | Leave a comment

Wiley Online

Abstract

This study aimed to examine the potential link between Bacillus cereus biofilm formation, virulence, and pathogenicity. The biofilm formation abilities of nine B. cereus strains isolated from food and two reference strains (ATCC 10876 and ATCC 25621) were measured using a crystal violet assay. Among the tested strains, three strains (GIHE 617-5, GIHE 86-09, and GIHE 728-17) and both reference strains were capable of biofilm formation. A positive correlation was obtained for higher cell surface hydrophobicity and increased biofilm formation. In contrast, HPLC analysis for elevated autoinducer-2 (Al-2) production revealed a negative impact on biofilm formation. PCR data indicated that all tested strains were capable of producing common B. cereus enterotoxins, including Hbl—A, C, and D, CytK, Nhe—B and C, EntFM, and BceT, but were negative for production of the emetic toxin cereulide and the pore-forming toxin Hly II. Meanwhile, RT-PCR data revealed a close correlation between high biofilm formation and the upregulation of several tested virulence genes for selected strains. However, elevated upregulation of virulence genes was not consistent in all of the higher biofilm-forming strains. Cytotoxicity analysis revealed higher virulence characteristics compared to those of low biofilm-forming strains.

Research Dry-surface foodborne pathogens under scrutiny at Purdue

Maintaining sanitary conditions without using water presents special challenges

WEST LAFAYETTE, Ind. – During 2021 and 2022, national news reported on four infants being hospitalized and two dying after consuming infant formula tainted with Cronobacter sakazakii. The reports sparked the prolonged shutdown of a production plant that produced large quantities of the formula, leading to a monthslong nationwide shortage of infant formula.

The incident motivated Purdue University’s Haley Oliver to launch a project to improve the safety of low-moisture food-processing facilities. Oliver, a professor of food science, will collaborate with Old Dominion University’s Rishi Drolia on the project, which will target the C. sakazakii pathogen.

“It was a massive-scale food safety challenge that led to a food security challenge,” Oliver said.
