Summary: Aeromonas spp. is an opportunistic bacterium that can cause infections in animals and humans. This study investigated the prevalence, virulence profile, and antimicrobial resistance of Aeromonas spp. in ready-to-eat foods. The results showed that temaki, a type of sushi, is a carrier of potentially pathogenic Aeromonas spp. and should be avoided by certain vulnerable populations. Constant monitoring of these microorganisms is necessary due to the presence of antimicrobial-resistant strains.

Summary: Ready-to-eat salads and berries are increasingly consumed in industrialized countries, but they can be contaminated by pathogenic parasites. In Italy, there is a lack of data on contamination of these products with parasite transmission stages, and more investigations are needed. This study found several species and assemblages of Cryptosporidium and Giardia duodenalis, as well as Entamoeba spp., in both local and imported fresh salads and berries. The results highlight the potential consequences on human health due to inadequate management of fresh produce.

Summary: Adjunct cultures are beneficial in enhancing the sensory characteristics and ripening process of cheeses through the production of specific enzymes that hydrolyze caseins. The study evaluated the effects of adjunct cultures on proteolytic activity and ACE inhibitors in cheese models during ripening, showing that adjunct cultures promoted primary and secondary proteolysis, accelerating the ripening process. Additionally, the cheese models with adjunct cultures had lower levels of bacteria during ripening compared to control cheeses.

Summary: Bacterial cellulose (BC) produced by acetic bacteria has various properties that make it suitable for wide-ranging industrial applications. BC, known for its high mechanical strength, thermal stability, and selective permeability, can be used as immobilizing material or carrier for living cells. It can enhance the quality of dairy products by emulsion stabilization, low-calorie food filling, and dietary fiber provision. Additionally, BC holds potential as a bioactive packaging material. Despite its potential, BC's use in the dairy industry is currently limited. Existing literature mainly discusses BC's applications as an emulsifier, fat substitute, carrier of bioactive substances, probiotics, and enzymes. This review presents recent advancements in BC's potential applications in the dairy industry.

Summary: This study investigated the growth kinetics of foodborne pathogen B. cereus during the commercial production of liquid egg yolk using PLA(2) treatment. The results showed that B. cytotoxicus NVH391-98 can grow prolifically at 50 degrees C, with estimated minimum, optimum, and maximum temperatures of 16.7-18.5, 47.8-48.1, and 52.1-52.4 degrees C, respectively. The dynamic model was validated with isothermal curves and it was found that holding the temperature below 15 degrees C or above 55 degrees C can effectively prevent the growth of B. cytotoxicus in egg yolk.

Summary: The infection mechanisms of Arcobacter are still uncertain. This study found that Arcobacter isolates from food and water sources were able to adhere and invade Caco-2 cells, and carried at least two virulence markers. A. butzleri showed higher virulent activity compared to A. cryaerophilus, while A. lanthieri, A. skirrowii, and A. vitoriensis exhibited even higher adhesion and invasion values. Sewage isolates were more adherent and invasive, and had a higher gene content. The association between cadF and hecA with high adhesion capability was identified for the first time.

Summary: Interactions between bacterial species in the formation of dual-species biofilms in the food industry are affected by environmental stresses, such as temperature and pH. This study found that the combination of cold and acid stresses significantly increased biofilm formation, and different temperatures resulted in variations in the presence of specific bacterial species and the secretion of extracellular substances. The findings provide valuable insights for addressing mixed biofilms in food processing under diverse stressful conditions.

Summary: This research investigates the role of flagella-related genes in the adhesion of E. coli O157:H7 and the effects of certain cations on bacterial adhesion and motility. The results demonstrate that flagellar-mediated motility is critical in the early stage of adhesion, and the presence of Fe2+, Ca2+, and Mn2+ affects the adhesion and motility of wildtype strains but not flagellar function-impaired strains. These findings provide new insights into the mechanisms of bacterial adhesion and have implications for the development of anti-adhesion agents.
