The sand-fixing desert shrub Artemisia sphaerocephala produces a large amount of seed mucilage, which plays crucial roles in the adaptation of this species to desert environments. Seed mucilage has been shown to be degraded by Phanerochaete chrysosporium from habitat soils, but the process and products of this degradation remain unclear. To fill this gap, we explored the factors and processes involved in mucilage degradation.

This is a timely and important review that focuses on the appropriateness of established cleaning, disinfection, and sterilization methods to safely and effectively address infectious fungal drug-resistant pathogens that can potentially contaminate reusable medical devices used in healthcare environment in order to mitigate the risk of patient infection. The release of the World Health Organization (WHO) fungal priority pathogen list (FPPL) in 2022 highlighted the public health crisis of antimicrobial resistance (AMR) in clinically relevant fungal species. Contamination of medical devices with drug-resistant fungal pathogens (including those on the FPPL) in healthcare is a rare event that is more likely to occur due to cross-transmission arising from lapses in hand hygiene practices. Established disinfection and sterilization methods decontaminate fungal pathogens on single-use and reusable medical devices; however, there are assumptions that reusable devices destined for semi-critical use are appropriately cleaned and do not harbour biofilms that may undermine the ability to effectively decontamination these type devices in healthcare. International standards dictate that manufacturer's instructions for use must provide appropriate guidance to healthcare facilities to meet safe reprocessing expectations that include addressing drug-resistant fungal pathogens. Increased environmental monitoring and vigilance surrounding fungal pathogens in healthcare is advised, including adherence to hand hygiene/aseptic practices and appropriate cleaning encompassing the simplification of reusable device features for 'ease-of-reach'. There are emereging opportunities to promote a more integrated multiactor hub approach to addressing these sophisticated challenges, including future use of artificial intelligence and machine learning for improved diagnostics, monitoring/surveillance (such as healthcare and wastewater-based epidemiology), sterility assurance, and device design. There is a knowledge gap surrounding the occurrence and potential persistence of drug-resistant fungal pathogens harboured in biofilms, particularly for ascertaining efficacy of high-level disinfection for semi-critical use devices.

To characterize Escherichia coli O25 ST131 (O25-ST131) isolated from Georgia poultry-a "global high-risk" clonal strain.

This study evaluated the phenotypic and genotypic traits of mcr-1.1-harboring Escherichia coli isolates from chickens, pigs, humans, and farm environments. The resistome and the mobile genetic elements associated with the spread of mcr-1.1 in Southern Brazil were also characterized.

The purpose of this study was to investigate the effects of Bacillus subtilis supplementation on the health of weaned piglets and whether Bacillus subtilis supplementation can reduce the damage of piglets induced by ETEC K88.

To investigate the effects of Lactococcus lactis subsp. lactis strains LL100933 and LL12007 on the host defense mechanisms of Caenorhabditis elegans against pathogenic infections and stressors.

Supplementing Lactobacillus alongside antibiotic treatment was a curative strategy to modulate gut microbiota and alleviate antibiotic-associated dysbiosis. But the lactobacilli that are used as probiotics are sensitive or have a low level of resistance to antibiotics, so they usually cannot achieve their beneficial effect, since they are killed by the applied antibiotics. This work aimed to develop the highly resistant Lactiplantibacillus plantarum subsp. plantarum ATCC14917 to cephalexin and evaluate its recovery effects of antibiotic-resistant L. plantarum on the antibiotic-disturbed intestinal microbiota using a mice model.

Enterococcus faecium is one of the most important opportunistic pathogens threatening human health worldwide. Resistance to vancomycin (VAN) is increasing at an alarming rate. Resurrecting antibiotics using a combination approach is a promising alternative avenue. Galangin (GAL) is a bioactive compound constituted in herbal plants. This study aimed to evaluate the synergistic activity of the combination of GAL and VAN and mode of action against vancomycin-resistant E. faecium (VREfm) strains.

Antimicrobial resistance (AMR), arising from decades of imprudent anthropogenic use of antimicrobials in healthcare and agriculture, is considered one of the greatest One Health crises facing healthcare globally. Antimicrobial pollutants released from human-associated sources are intensifying resistance evolution in the environment. Due to various ecological factors, wildlife interact with these polluted ecosystems, acquiring resistant bacteria and genes. Although wildlife are recognized reservoirs and disseminators of AMR in the environment, current AMR surveillance systems still primarily focus on clinical and agricultural settings, neglecting this environmental dimension. Wildlife can serve as valuable sentinels of AMR in the environment, reflecting ecosystem health, and the effectiveness of mitigation strategies. This review explores knowledge gaps surrounding the ecological factors influencing AMR acquisition and dissemination in wildlife, and highlights limitations in current surveillance systems and policy instruments that do not sufficiently address the environmental component of AMR. We discuss the underutilized opportunity of using wildlife as sentinel species in a holistic, One Health-centred AMR surveillance system. By better integrating wildlife into systematic AMR surveillance and policy, and leveraging advances in high-throughput technologies, we can track and predict resistance evolution, assess the ecological impacts, and better understand the complex dynamics of environmental transmission of AMR across ecosystems.

Bacillus subtilis is usually found in soil, and their biocontrol and plant growth-promoting capabilities are being explored more recently than ever. However, knowledge about metabolite production and genome composition of endophytic B. subtilis from seeds is limited. In the present study, B. subtilis EVCu15 strain isolated from the seeds of Vasconcellea cundinamarcensis (mountain papaya) was subjected to whole genome sequencing and detailed molecular and functional characterization.

Wild bees foster diverse microbiota that may determine survival success of developing larvae. Here, we compare survivorship and microbial communities of Ceratina calcarata small carpenter bees reared from eggs across three treatments: maternally collected control provisions with diverse microbiota, sterile provisions, and probiotic provisions supplemented with a beneficial symbiont, Apilactobacillus kunkeei.

Expansion of the microbial drug discovery pipeline has been impeded by a limited and skewed appreciation of the microbial world and its full chemical capabilities and by an inability to induce silent biosynthetic gene clusters (BGCs). Typically, these silent genes are not expressed under standard laboratory conditions, instead requiring particular interventions to activate them. Genetic, physical, and chemical strategies have been employed to trigger these BGCs, and some have resulted in the induction of novel secondary metabolites. This review encompasses a wide range of literature and emphasizes selected successful induction of microbial secondary metabolites examples through unconventional approaches such as quorum sensing, epigenetic modulation, and ribosome engineering. Whenever applicable, we will also discuss their mechanisms and optimizations to improve the microbial drug discovery process.

In the present study, we tested if terrestrially-derived humic substances (HS) could mitigate the adverse effects of elevated temperature and UVB radiation on the bacterial communities of two hard corals (Montipora digitata and Montipora capricornis), one soft coral (Sarcophyton glaucum), sediment and water. We also examined the impact of temperature, UVB radiation and HS supplementation on coral photosynthetic activity, a proxy for coral bleaching.
