Summary: This study confirmed that spoilage bacteria can enter the VBNC state and identified a case of beer spoilage caused by VBNC Pediococcus damnosus cells using a novel procedure. The combination of genomic sequencing, flow cytometry, and routine culturing can provide direct evidence of VBNC cells in spoiled food samples and aid in further research on food safety issues caused by VBNC microbes.

Summary: The viable but nonculturable (VBNC) state is a survival strategy for bacteria in unfavorable conditions. Resuscitation is the recovery of VBNC cells, which is necessary for proof of their existence. The resuscitation of VBNC cells has been widely studied for risk control and potential applications in the food industry.

Summary: It was found that Rhodococcus biphenylivorans TG9 enters a viable but nonculturable (VBNC) state under anaerobic conditions, leading to a significant reduction in metabolic activity and degradation ability. However, resuscitation by providing oxygen can restore the degrading capacity of TG9 in the VBNC state, providing a new strategy to cope with survival under anaerobic conditions.

Summary: The viable but nonculturable (VBNC) state of Staphylococcus aureus can be induced in citric acid buffer at -20 degrees C, causing changes in some biological characteristics, but can be successfully resuscitated under various conditions. The food industry should pay attention to the potential hazard posed by VBNC S. aureus under frozen conditions.

Summary: Members of the Proteobacteria can enter a viable but non culturable (VBNC) state as a survival strategy under stressful conditions. Using Vibrio parahaemolyticus as a model organism, distinct subpopulations in the VBNC state with different resuscitation potentials and proteomic profiles were identified. Deletion of the lactate dehydrogenase gene triggered cells to enter VBNC state, while lactate addition extended resuscitation potential. The ability to survive in VBNC state may be linked to overcoming oxidative stress.

Summary: Salmonella spp. is a major cause of foodborne outbreaks worldwide. This study found that Salmonella can enter a viable but nonculturable (VBNC) state in liquid egg products, and under certain conditions, can resuscitate. This has important implications for food safety and understanding the health risks associated with Salmonella.

Summary: The natural compound zerumbone extracted from Zingiber zerumbet Smith was found to inhibit the urease activity of H. pylori by forming dimers, trimers, or tetramers, suggesting its potential as a therapeutic agent for treating H. pylori infections in humans.

Summary: This study reviewed 12 clinical studies and found that the vonoprazan-sitafloxacin-amoxicillin regimen is a good option for third-line Helicobacter pylori eradication treatment, although extending the treatment duration may further improve eradication rates. Confirmation of drug susceptibility before using sitafloxacin is recommended due to safety concerns related to fluoroquinolones.

Summary: This study evaluated humoral responses to a nearly complete H. pylori immunoproteome among GC cases and controls, finding higher prevalence of certain antibodies in controls and lower seroprevalence in GC cases, suggesting immune protection and potential changes in specific proteins.

Summary: This study evaluated the antibiotic resistance of H. pylori in Egyptian patients. The results showed that H. pylori has high resistance to metronidazole and amoxicillin, while having low resistance to quinolones. This has important implications for the choice of eradication therapy for H. pylori in Egypt.

Summary: The study found a correlation between age, endoscopic manifestations, and the effectiveness of H. pylori eradication therapy. Patients over 60 years old and those with multiple white and flat elevated lesions in endoscopic examination were more likely to fail H. pylori eradication with empirical quadruple therapy. On the other hand, patients with diffuse redness in endoscopic examination were more likely to succeed in H. pylori eradication therapy with empirical quadruple therapy.

Summary: The study found that Urolithin A (UA) effectively attenuates the inflammation caused by Helicobacter pylori (H. pylori) and reduces tissue damage in mice. In addition, UA decreases the relative abundance of Helicobacteraceae in the feces of H. pylori-infected mice.

Summary: Microbial-driven nitrogen removal is crucial in full-scale wastewater treatment plants (WWTPs), and understanding the nitrogen cycling networks is essential for optimizing these processes. This study used metagenomics and metatranscriptomics to investigate the microbial nitrogen removal processes in a full-scale WWTP. The study found a simultaneous nitrification-anammox-denitrification (SNAD) process, where ammonia was oxidized by AOB, AOA, and NOB, and the resulting nitrite and nitrate were reduced to N2 by anammox and denitrifying bacteria. The study also identified specific anammox bacteria and highlighted their potential for efficient nitrogen removal.
