is an Enterobacteriaceae that is abundant in water and causes food and waterborne infections in fish, animals, and humans. The bacterium causes Edwardsiellosis in farmed fish and can lead to severe economic losses in aquaculture worldwide. is an intracellular pathogen that can also cause systemic infection. Type III and type VI secretion systems are the bacterium's most lethal weapons against host defenses. It also possesses multi-antibiotic resistant genes and is selected and enriched in the environment due to the overuse of antibiotics. Therefore, the bacterium has great potential to contribute to the evolution of the resistome. All these properties have made this bacterium a perfect model to study bacteria virulence mechanisms and the spread of antimicrobial genes in the environment. We summarize recent advance in biology and provide insights into future research in virulence mechanisms, vaccine development and novel therapeutics.

Introduction: Molecular surveillance is an important tool for detecting chains of transmission and controlling the HIV epidemic. This can also improve our knowledge of molecular and epidemiological factors for the optimization of prevention. Our objective was to illustrate this by studying the molecular and epidemiological evolution of the cluster including the new circulating recombinant form (CRF) 94_cpx of HIV-1, detected in 2017 and targeted by preventive actions in 2018.

Carbon catabolite repression (CCR) and de-repression (CCDR) are critical for fungal development and pathogenicity, yet the underlying regulatory mechanisms remain poorly understood in pathogenic fungi. Here, we identify a serine/threonine protein phosphatase catalytic subunit, Pp4c, as essential for growth, conidiation, virulence, and the utilization of carbohydrates and lipids in Magnaporthe oryzae. We demonstrate that the protein phosphatase 4 complex (Pp4c and Smek1 subunits), the AMP-activated protein kinase (AMPK) Snf1, and the transcriptional regulators CreA (repressor) and Crf1 (activator) collaboratively regulate the utilization of non-preferred carbon sources.

Single-cell transcriptomics of bronchoalveolar lavage during PRRSV infection with different virulence.

Nat Commun

Porcine reproductive and respiratory syndrome virus (PRRSV) causes significant economic losses in the global swine industry due to its high genetic diversity and different virulence levels, which complicate disease management and vaccine development. This study evaluated longitudinal changes in the immune cell composition of bronchoalveolar lavage fluid and the clinical outcomes across PRRSV strains with varying virulence, using techniques including single-cell transcriptomics. In highly virulent infection, faster viral replication results in an earlier peak lung-damage time point, marked by significant interstitial pneumonia, a significant decrease in macrophages, and an influx of lymphocytes.

Microcosm experiments deciphered resistome coalescence, risks and source-sink relationship of antibiotic resistance in the soil irrigated with reclaimed water.

College of Water Sciences, Beijing Normal University, No 19, Xinjiekouwai Street, Beijing 100875, China; Engineering Research Center of Groundwater Pollution Control and Remediation, Ministry of Education, Beijing, 100875, China. Electronic address:

Reclaimed water is widely used in agriculture irrigation to alleviate water scarcity, whereas the dissemination of antibiotic resistance genes (ARGs) in the soil it introduces has attracted widespread attention. Currently, few studies have systematically elucidated the coalescence of the resistome originating from reclaimed water with the soil's native community. Also, the effects and mechanisms of irrigation on the dissemination of ARGs in soils have yet to be demonstrated.

Bioorganic compounds in quorum sensing disruption: strategies, Mechanisms, and future prospects.

Quorum Sensing Laboratory, Centre for Research in Infectious Diseases (CRID), School of Chemical and Biotechnology, SASTRA Deemed to be University, Thanjavur 613401, India. Electronic address:

Recent research has shed light on the complex world of bacterial communication through quorum sensing. This sophisticated intercellular signalling mechanism, driven by auto-inducers, regulates crucial bacterial community behaviours such as biofilm formation, expression of virulence factors, and resistance mechanisms. The increasing threat of antibiotic resistance, coupled with quorum sensing mediated response, necessitates alternative strategies to combat bacterial infections.
