Summary: Marine invertebrates, such as the brown shrimp, are known to ingest both natural and anthropogenic microplastics. In this study, it was found that exposure to various types of microplastics did not induce an oxidative stress response in the shrimp's digestive gland tissue. This suggests that the shrimp may have adapted to frequent ingestion of non-digestible particles and do not require continuous biochemical defense.

Summary: This study investigated the mortality rates of brown shrimp in the commercial shrimp fishery in the German Bight. It found that previous studies severely underestimated the mortality rates of undersized shrimps in the bycatch. The use of sieving methods also significantly affected shrimp mortality rates, and there might be an unknown additional source of mortality.

Summary: Crangon crangon shows high variability in recruitment and stock development. The share of ovigerous females is influenced by season and temperature, with warmer winters facilitating embryogenesis and larval hatch. The temperature sums from November to April are significantly correlated with the lowest winter water temperatures, providing an indication for the appearance of C. crangon larvae.

Summary: Experimental results indicate that brown shrimp only ingest sediment while feeding, not intentionally sand grains. This suggests that sand grains do not seem to have a crucial function in food processing and digestion in brown shrimp.

Summary: This study analyzed 35 years of brown shrimp monitoring in the western Dutch Wadden Sea, revealing that shrimp settlement on mudflats advanced in timing and increased in density, correlating with seawater temperature changes. Four interpretations were proposed to explain these changes, each potentially leading to different scenarios in a warming world.

Summary: This study aimed to investigate the impact of moisture content and temperature on fungal growth in rice under different storage conditions. The results showed that high temperature and moisture were favorable for the growth of dominant strains, and PCR-DGGE could identify some uncultured strains. This study provides a foundation for understanding the evolution of fungal flora in rice during storage in China and may contribute to the development of biological control methods for preventing mold contamination in rice.

Summary: This study aims to develop a direct polymerase chain reaction (PCR) method for the detection of trace levels of spoilage lactic acid bacteria (LAB) in beer, without the need for traditional culturing processes. By using pressure cycling technology and a mixed cellulose ester filter, the DNA recovery rate for PCR detection was improved, and the DNA extraction process was optimized. This method successfully detected 1 cell of LAB in every 300 ml of beer.

Summary: Biosecurity appears to be a promising tool for controlling Campylobacter on poultry farms, while partial depopulation seems to be a significant risk factor for introducing the bacteria. Campylobacter colonization in broilers typically occurs at four weeks of age, and cattle and swine do not appear to be sources of flock colonization. Metabarcoding analysis revealed that Campylobacter-free flocks carried high relative abundances of Megamonas in their ceca, suggesting potential competition with Campylobacter.

Summary: In this study, it was found that a resistance plasmid could transfer rapidly to coliforms and anaerobes in the human gut, independent of the initial donor concentration, antibiotic treatment, and individual differences. The presence and quantity of the plasmid were confirmed and antibiotic treatment showed a significant reduction in resistant coliforms.

Summary: The study found that antibiotic residues and antibiotic resistant bacteria are more prevalent in fattening calf slurry than in beef cattle farmyard manure used for agricultural field fertilization. Specifically, higher concentrations of antibiotics like oxytetracycline, ciprofloxacin, and enrofloxacin were detected in fattening calf slurry samples. Additionally, a greater percentage of E. coli isolates from fattening calf slurry were resistant to multiple antibiotics compared to those from beef cattle farmyard manure.

Summary: This study aimed to analyze acquired antibiotic-resistance genes (ARGs) in the intestinal microbiome of two important food-animal species in Hungary from a One Health perspective. The results revealed different types of acquired ARGs in domestic pigs and carp, some of which have not been reported in Hungarian food animals. The presence of certain ARGs in both domestic and wild animal populations suggests a possible relationship.

Summary: This article provides an overview of biogenic amines (BAs) in the context of food quality and safety, focusing on their detection and quantification in analytical laboratories and on-site detection throughout the food chain. Various types of sensors, including chemosensors and bio/biomimetic sensors, are discussed, along with different receptors such as enzymes, antibodies, molecularly imprinted polymers (MIPs), and aptamers. The article concludes with an assessment of the limitations of BA sensors, a technological forecast, and thoughts on short-term solutions.

Summary: This study investigated interspecies interactions in mixed-species biofilms and revealed dynamic social interactions among bacteria, including commensalism, exploitation, and amensalism. The keystone species M. lacticum was found to enhance the growth of other species, leading to synergy in biofilm mass. The findings can be applied to cultivate, engineer, and design synthetic bacterial communities based on interaction-mediated approaches.

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: The study found that CpxAR TCS is an important regulatory mechanism for the virulence of C. sakazakii. Mutants showed weakened adhesion, invasion, and survival ability, and exhibited attenuated virulence in animal models. In addition, CpxAR TCS is involved in regulating the expression of genes associated with bacterial virulence and cellular invasion.

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.
