Summary: Escherichia coli that produce ESBLs and pAmpCs pose a serious threat to public health as these genes confer resistance to critically important antibiotics and can be transferred to non-resistant bacteria through plasmids. In this study, 102 ESBL/pAmpC-producing E. coli isolated from broiler production were found to have the ability to form biofilms, with certain genetic factors and virulence genes associated with increased biofilm capability. Efforts should be made to reduce the presence of ESBL/pAmpC-producing E. coli and biofilms in the broiler production pyramid to minimize the risk of dissemination of resistant bacteria and genes.

Summary: The development of bacterial resistance to antibiotics is a growing public health concern exacerbated by the formation of biofilms. The study aimed to evaluate the anti-quorum sensing (QS), anti-biofilm, and anti-virulence activities of the beta-adrenoreceptor blocker atenolol against Gram-negative bacteria. In silico studies showed that atenolol had a significant binding affinity to the QS receptors of the tested bacteria. In vitro and in vivo experiments demonstrated that atenolol effectively competed with QS proteins, downregulated the expression of QS- and virulence-encoding genes, and reduced bacterial biofilm formation, virulence enzyme production, and motility. It also protected mice from bacterial infection. These findings suggest that atenolol has potential as an adjuvant in the treatment of aggressive bacterial infections.

Summary: We investigated the antimicrobial activity of sertraline against Listeria monocytogenes, and its effects on biofilm formation and virulence gene expression. Sertraline showed inhibitory effects on L. monocytogenes at concentrations between 16-32 μg/mL and a bactericidal effect at 64 μg/mL. Sertraline damaged the cell membrane, decreased ATP and intracellular pH, and reduced biofilm formation efficiency. Importantly, low concentrations of sertraline down-regulated the expression of various virulence genes in L. monocytogenes.

Summary: The induction of natural competence in Staphylococcus aureus occurs in response to ROS and host defenses during infection. Bacteria cope with reduced respiration by increasing the rate of glycolysis and obtaining energy through fermentation. Natural competence provides S. aureus with additional nutritional and metabolic possibilities, fostering genetic variability and allowing it to proliferate during infection.

Summary: New antimicrobials are urgently needed for combatting drug-resistant Gram-negative bacteria, and a copolymer without a defined sequence shows promise in selectively targeting these bacteria. The copolymer interacts strongly with the bacterial lipopolysaccharides, but not with mammalian cell membranes, making it non-toxic. This new approach provides a concept for designing antibiotics specifically targeting drug-resistant and biofilm-forming Gram-negative bacteria.

Summary: The study found that the UASB bioreactor inoculated with flocculent sludge showed higher operational efficiency and methane production rate in treating olive mill wastewater, compared to the other bioreactors inoculated with granular sludge which exhibited lower performance possibly due to the negative impact of OMW phenolics. Acidogenesis in all reactors was mainly carried out by Clostridiales and Sporolactobacillus spp. The methane-producing archaeon Methanobacterium beijingense was the dominant species in the granular sludge inoculated reactors, while a novel archaeal methanogen was exclusively dominating in the UASB-F bioreactor.

Summary: Pollution from heavy metals is a significant global environmental concern caused by human activities such as mining, farming, and manufacturing. This pollution can harm crops, disrupt the food chain, and pose a threat to human health. Phytoremediation, a method that uses plants to remove heavy metals, is the most controllable and eco-friendly solution. However, the effectiveness of phytoremediation depends on the bioavailability of heavy metals in soil and the biomass of plants. This study examines different techniques and frameworks for heavy metal removal, emphasizing the challenges and limitations of phytoremediation and its potential application in addressing other harmful pollutants.

Summary: The accumulation of both natural and anthropogenic sources of metals in the ecosystem has led to increasing concerns over heavy metal (HM) pollution. Human exposure to HMs, such as mercury, arsenic, lead, chromium, and cadmium, has become a significant environmental and health issue. These HMs can cause acute or chronic poisoning through water, air, or food. Their bioaccumulation in the body leads to various toxic effects on organs and tissues, primarily through the production of reactive oxygen species, enzyme inactivation, and oxidative stress. Conventional techniques for HM removal are limited, especially when the HM concentration is low. Microbial bioremediation, utilizing organisms like fungi and bacteria, has emerged as a potential solution due to their superior biosorption and bioaccumulation capabilities. This review aims to provide insights into HM uptake, toxicity mechanisms, and the management of metal poisoning through the selection of microbial remediation technology.

Summary: In this study, two bacteriophages, PECP14 and PECP20, infecting Escherichia coli O157:H7 were isolated and found to be stable under different environmental conditions. These phages exhibited specificity in targeting different host receptors and demonstrated the ability to infect other foodborne pathogens. The efficacy of phage treatment was demonstrated through rapid adsorption and bacterial lysis. Furthermore, purified endolysins derived from these phages showed remarkable bacteriolytic activity not only against E. coli O157:H7 but also against other pathogens. These findings suggest that these phages and their endolysins can be used for biological control of E. coli O157:H7 in various stages of agricultural product production.

Summary: The effect of multiple sublethal doses of non-thermal plasma treatments on phenotypical changes and the reduction in phytopathogenicity of three species of fungi was investigated. The plasma damaged the surface of the fungal hyphae, decreased their dry biomass, and affected the activity of pectinase and xylanase. Furthermore, the plasma treatments increased the germination rate of artificially infected cucumber seeds and resulted in plants with higher biomass and longer roots and stems. However, the reduction in phytopathogenicity was not complete after the multiple plasma treatments.
