Bacillus cereus sensu lato organisms are an ecologically diverse group that includes etiologic agents of food poisoning, periodontal disease, and anthrax. The recently identified Bcp1 bacteriophage infects B. cereus sensu lato and is being developed as a therapeutic decontamination agent and diagnostic countermeasure. We announce the complete genome sequence of Bcp1.

sensu lato () comprises mesophilic and psychrotolerant bacteria commonly found in natural environments as well as in organic and conventional milk. Due to their potential toxigenicity and antibiotic resistance, these bacteria pose a significant threat to consumer health. Organic milk production, which prohibits the use of antibiotics and artificial additives, may influence the composition of microbiota between milk types.

The diagnosis of anthrax, a zoonotic disease caused by Bacillus anthracis can be complicated by detection of closely related species. Conventional diagnosis of anthrax involves microscopy, culture identification of bacterial colonies and molecular detection. Genetic markers used are often virulence gene targets such as B.

As the interest in plant-based alternative food products has increased significantly in the last years, it is also important to investigate these products regarding microbiological aspects. The aim of this study was to assess the microbiological quality and the occurrence of selected foodborne pathogens in plant-based meat alternative products (PBMA) collected at retail level in Switzerland. A total of 100 PBMA (84 vegan and 16 vegetarian products) was analyzed qualitatively for the presence of Salmonella, Listeria monocytogenes and quantitatively for Staphylococcus aureus, Bacillus cereus group members, Enterobacteriaceae, and the total viable count.

The group represents a serious risk in powdered and amylaceous foodstuffs. Cold plasma (the fourth state of matter) is emerging as an alternative effective nonthermal technology for pasteurizing a wide range of matrices in solid, liquid, and powder form. The present study aims to evaluate the mechanisms involved in inactivation via cold plasma, focusing on (i) the technology's ability to generate damage in cells (at the morphological and molecular levels) and (ii) studying the effectiveness of cold plasma in biofilm mitigation through the direct effect and inhibition of the biofilm-forming capacity of sublethally damaged cells post-treatment.
