Highly pathogenic H5N1 avian influenza virus outbreak in cattle: the knowns and unknowns Nat. Rev. Microbiol. (IF 69.2) Pub Date : 2024-07-25 Gabriele Neumann, Yoshihiro Kawaoka
Highly pathogenic avian influenza (HPAI) viruses have occasionally infected humans, often with severe outcomes. Reports of HPAI in dairy cattle and the detection of high titres of the virus in cattle milk in the United States are therefore a cause for concern. Documented human infections linked to cattle infections, though mild, highlight the urgent need for enhanced biosecurity and vigilant monitoring

Scarcity of fixed carbon transfer in a model microbial phototroph-heterotroph interaction ISME J. (IF 10.8) Pub Date : 2024-07-25 Sunnyjoy Dupuis, Usha F Lingappa, Xavier Mayali, Eve S Sindermann, Jordan L Chastain, Peter K Weber, Rhona Stuart, Sabeeha S Merchant
Although the green alga Chlamydomonas reinhardtii has long served as a reference organism, few studies have interrogated its role as a primary producer in microbial interactions. Here, we quantitatively investigated C. reinhardtii’s capacity to support a heterotrophic microbe using the established coculture system with Mesorhizobium japonicum, a vitamin B12-producing α-proteobacterium. Using stable

Dark carbon fixation (DCF), conducted mainly by chemoautotrophs, contributes greatly to primary production and the global carbon budget. Understanding the response of DCF process to climate warming in coastal wetlands is of great significance for model optimization and climate change prediction. Here, based on a four-year field warming experiment (average annual temperature increase of 1.5°C), DCF

Divergent molecular strategies drive evolutionary adaptation to competitive fitness in biofilm formation ISME J. (IF 10.8) Pub Date : 2024-07-25 Mingxing Tang, Ruixue Yang, Zilin Zhuang, Shuhong Han, Yunke Sun, Peiyu Li, Kewei Fan, Zhao Cai, Qiong Yang, Zhijian Yu, Liang Yang, Shuo Li
Biofilm is a group of heterogeneously structured and densely packed bacteria with limited access to nutrients and oxygen. These intrinsic features can allow a mono-species biofilm to diversify into polymorphic subpopulations, determining the overall community’s adaptive capability to changing ecological niches. However, the specific biological functions underlying biofilm diversification and fitness

From vacant to vivid: The nutritional landscape drives infant gut microbiota establishment Mol. Microbiol. (IF 2.6) Pub Date : 2024-07-24 Reut Melki, Yael Litvak
From the moment of birth, the newborn gastrointestinal tract is infiltrated by various bacteria originating from both maternal and environmental sources. These colonizing bacteria form a complex microbiota community that undergoes continuous changes until adulthood and plays an important role in infant health. The maturation of the infant gut microbiota is driven by many factors and follows a distinct

Chlamydiae as symbionts of photosynthetic dinoflagellates ISME J. (IF 10.8) Pub Date : 2024-07-23 Justin Maire, Astrid Collingro, Kshitij Tandon, Vanta J Jameson, Louise M Judd, Matthias Horn, Linda L Blackall, Madeleine J H van Oppen
Chlamydiae are ubiquitous intracellular bacteria and infect a wide diversity of eukaryotes, including mammals. However, chlamydiae have never been reported to infect photosynthetic organisms. Here, we describe a novel chlamydial genus and species, Candidatus Algichlamydia australiensis, capable of infecting the photosynthetic dinoflagellate Cladocopium sp.

Vertical confinement enhances surface exploration in bacterial twitching motility Environ. Microbiol. (IF 4.3) Pub Date : 2024-07-23 Xiao Chen, Rongjing Zhang, Junhua Yuan
Bacteria are often found in environments where space is limited, and they attach themselves to surfaces. One common form of movement on these surfaces is bacterial twitching motility, which is powered by the extension and retraction of type IV pili. Although twitching motility in unrestricted conditions has been extensively studied, the effects of spatial confinement on this behaviour are not well

When the going gets tough, the tough get going—Novel bacterial AAA+ disaggregases provide extreme heat resistance Environ. Microbiol. (IF 4.3) Pub Date : 2024-07-23 Valentin Bohl, Axel Mogk
Heat stress can lead to protein misfolding and aggregation, potentially causing cell death due to the loss of essential proteins. Bacteria, being particularly exposed to environmental stress, are equipped with disaggregases that rescue these aggregated proteins. The bacterial Hsp70 chaperone DnaK and the ATPase associated with diverse cellular activities protein ClpB form the canonical disaggregase

Arthropods, such as houseflies, play a significant role on the dissemination of antimicrobial resistance (AMR); however, their impact has often been overlooked in comparison to other AMR vectors. Understanding the contribution of arthropods to the spread of AMR is critical for implementing robust policies to mitigate the spread of AMR across “One Health” sectors. Herein, we investigated the in-situ

Globally distributed bacteriophage genomes reveal mechanisms of tripartite phage-bacteria-coral interactions ISME J. (IF 10.8) Pub Date : 2024-07-18 Bailey A Wallace, Natascha S Varona, Poppy J Hesketh-Best, Alexandra K Stiffler, Cynthia B Silveira
Reef-building corals depend on an intricate community of microorganisms for functioning and resilience. The infection of coral-associated bacteria by bacteriophages can modify bacteria-host interactions, yet very little is known about phage functions in the holobiont. This gap stems from methodological limitations that have prevented the recovery of high-quality viral genomes and bacterial host assignment

Phenotypic plasticity, which involves phenotypic transformation in the absence of genetic change, may serve as a strategy for organisms to survive in complex and highly-fluctuating environments. However, its reaction norm, molecular basis, and evolution remain unclear in most organisms, especially microbial eukaryotes. In this study, we explored these questions by investigating the reaction norm, regulation

In recent years, phylogenetic reconciliation has emerged as a promising approach for studying microbial ecology and evolution. The core idea is to model how gene trees evolve along a species tree, and to explain differences between them via evolutionary events including gene duplications, transfers, and losses. Here, we describe how phylogenetic reconciliation provides a natural framework for studying
