It is generally accepted that Clostridium perfringens strains associated with food poisoning carry their enterotoxin gene, cpe, on the chromosome, while C. perfringens strains isolated from non-food-borne diseases, such as antibiotic-associated diarrhea and sporadic diarrhea, carry cpe on the plasmid. However, we recently encountered a food poisoning outbreak caused by C. perfringens bearing a plasmid cpe. We therefore investigated a total of 31 clinical and non-clinical C. perfringens strains to locate the cpe gene by PCR. The cpe of nine heat-sensitive (100 degrees C for 10min) strains isolated from three outbreaks of food poisoning were located on the plasmid, while those of six heat-resistant strains from other food poisoning outbreaks were located on the chromosome. Moreover, the cpe of 5 heat-sensitive strains isolated from healthy human feces and those of 11 heat-sensitive soil strains were also located on the plasmid. These findings indicate that heat-sensitive, cpe-plasmid-borne C. perfringens strains should not be disregarded as causative agents of food poisoning.

In the United States, typhoid vaccination is recommended for international travelers to areas with a recognized risk of typhoid exposure. Using MarketScan® Commercial Database from 2016 through 2022, we estimated typhoid vaccination costs by route (injectable vs. oral) and provider setting (clinic vs.

Bongkrekic acid (BA) toxin, produced by Burkholderia gladioli pathovar cocovenenans bacteria, has been implicated in foodborne illness outbreaks. BA poisoning is associated with rice noodle consumption; hence, this study investigated B. cocovenenans growth and BA production in wet rice noodles comprising varying starch ratios, starch types, rice nutrients, and saccharides.

Objective: Bongkrekic acid (BKA) is a life-threatening toxin linked to foodborne illnesses. Herein, we report two fatalities among 33 patients who ingested BKA in March 2024, East Taipei, Taiwan.
Case Report: Our first case involved a 40-year-old female who presented with nausea, vomiting, and diarrhea after consuming wet rice noodles.

() is a major pathogenic bacterium responsible for bacterial foodborne diseases, making its rapid, specific, and accurate detection crucial. In this study, we develop a ratiometric biosensor based on the recombinase polymerase amplification-clustered regularly interspaced short palindromic repeats/CRISPR associated protein 12a (RPA-CRISPR/Cas12a) system and Eu-metal-organic framework (Eu-MOF) fluorescent nanomaterials for the high-sensitivity detection of , combining with RPA for efficient isothermal amplification, this sensor enhances specificity and sensitivity by utilizing the target activation of CRISPR/Cas12a. The Eu-MOF serves a dual function, providing stable red fluorescence as a reference signal and adsorbing FAM-labeled probes for fluorescence quenching, forming a dual-signal system that significantly reduces background interference.
