“…In addition, several enteropathogenic bacteria use bile salt components to trigger and/or regulate virulence factors, allowing the microorganism to maintain infection (Table 2). Some archetypal Gram-negative enteropathogens, such as V. cholerae, Salmonella, Shigella, and Pseudomonas aeruginosa (although this bacterium preferentially infects the urinary tract, it occasionally reaches the gastrointestinal tract, as it is resistant to a variety of compounds, including bile salts and brilliant green [54,71]) exploit this mechanism to assist in pathogenicity. Conversely, certain Gram-positive bacteria, including Staphylococcus, Listeria monocytogenes and Clostridium perfringens, are known to colonize the human gut, hence posing the question: how can they overcome the challenge posed by bile salts?…”

The microbiota present in the gastrointestinal tract is involved in the development or prevention of food allergies and autoimmune disorders; these bacteria can enter the gallbladder and, depending on the species involved, can either be benign or cause significant diseases. Occlusion of the gallbladder, usually due to the presence of calculi blocking the bile duct, facilitates microbial infection and inflammation, which can be serious enough to require life-saving surgery. In addition, the biliary salts are secreted into the intestine and can affect the gut microbiota. The interaction between the gut microbiota, pathogenic organisms, and the human immune system can create intestinal dysbiosis, generating a variety of syndromes including the development of food allergies and autoimmune disorders. The intestinal microbiota can aggravate certain food allergies, which become severe when the integrity of the intestinal barrier is affected, allowing bacteria, or their metabolites, to cross the intestinal barrier and invade the bloodstream, affecting distal body organs. This article deals with health conditions and severe diseases that are either influenced by the gut flora or caused by gallbladder obstruction and inflammation, as well as putative treatments for those illnesses.

“…[23] Another wellknown selective agent is the dye, Brilliant Green, used to inhibit gram-positive bacteria as well as some gram-negatives. [24,25] A further advancement in the field of selective culture media was the addition of specific fluorogenic or chromogenic enzyme substrates to selective agar. These allow for the detection and enumeration of target bacteria based on the presence of fluorescence or a distinct color change due to the release of a chromogen.…”

In order to prevent microbial contamination of food, monitoring of the production environment, together with the rapid detection of foodborne pathogens have proven to be of utmost importance for Food Safety. Environmental monitoring should detect harmful pathogens at the earliest point in time in order for the necessary interventions to be taken. However, current detection methods fall short with regards to speed, ease of use, and cost. This article aims to present the idea behind NEMIS Technologies, a startup company making use of the novel AquaSparkTM technology for the development of a new generation of bacterial detection methods. These methods utilize chemiluminescence in order to detect live target bacteria in a short period of time compared to that of conventional methods. We show that dry-stressed Listeria monocytogenes can be detected within 24 hours, using small-molecule chemiluminescent probes, together with a bacteria-specific proprietary enrichment broth containing a cocktail of bacteriophages, which enhance the specificity and sensitivity. This novel platform technology has the potential to extend beyond environmental monitoring towards food analyses as well as veterinary and human health.
