- Abstract:
- ... Coral reefs are rapidly declining because of widespread mass coral bleaching causing extensive coral mortality. Elevated seawater temperatures are the main drivers of coral bleaching, and climate change is increasing the frequency and severity of destructive marine heatwaves. Efforts to enhance coral thermal bleaching tolerance can be targeted at the coral host or at coral-associated microorganism ...

- Abstract:
- ... Birds harbor complex gut bacterial communities that may sustain their ecologies and facilitate their biological roles, distribution, and diversity. Research on gut microbiomes in wild birds is surging and it is clear that they are diverse and important – but strongly influenced by a series of environmental factors. To continue expanding our understanding of how the internal ecosystems of birds wor ...

- Abstract:
- ... Candida auris is a recently emerged yeast pathogen of humans causing severe hospital-acquired systemic infections. It is of the utmost importance to understand the genetic and cellular basis of its virulence and pathogenicity. In a recent study, Santana and O’Meara generated forward and reverse genetic tools to manipulate C. auris. ...

- Abstract:
- ... Paleovirology is the study of ancient viruses and how they have coevolved with their hosts. An increasingly detailed understanding of the diversity, origins, and evolution of the DNA viruses of eukaryotes has been obtained through the lens of paleovirology in recent years. Members of multiple viral families have been found integrated in the genomes of eukaryotes, providing a rich fossil record to ...

- Abstract:
- ... Fatty acids (FAs) are potent antimicrobials which hold great promise as viable alternatives or complements to conventional antibiotics. Intriguingly, bacteria are well equipped to use environmental FAs as energy sources and/or building blocks for their membrane lipids. Furthermore, these microbes display a wide array of mechanisms to prevent or mitigate FA toxicity. In this review we discuss strat ...

- Abstract:
- ... Disposal of electrons generated during the fermentation of ingested feed is a fundamental feature of anaerobic microbial gut ecosystems. Here, we focus on the well-studied rumen environment to highlight how electrons are transferred through anaerobic fermentation pathways and how manipulating this electron flow is important to reducing methane emissions from ruminants. Priorities for research that ...

- Abstract:
- ... Glycans are expressed on the surface of nearly all host and bacterial cells. Not surprisingly, glycan-mediated molecular interactions play a vital role in bacterial pathogenesis and host responses against pathogens. Glycan-mediated host–pathogen interactions can benefit the pathogen, host, or both. Here, we discuss (i) bacterial glycans that play a critical role in bacterial colonization and/or im ...

- Abstract:
- ... Iron is an essential micronutrient for the ecologically important photoautotrophic cyanobacteria which are found across diverse aquatic environments. Low concentrations and poor bioavailability of certain iron species exert a strong control on cyanobacterial growth, affecting ecosystem structure and biogeochemical cycling. Here, we review the iron-acquisition pathways cyanobacteria utilize for ove ...

- Abstract:
- ... The composition of the gut microbiome is greatly influenced by nutrition and dietary alterations which can also induce large temporary microbial shifts. However, the molecular mechanisms that promote these changes remain to be determined. Species of the family Lactobacillaceae and Bacillus species are genetically manipulatable bacteria that are naturally found in the human gastrointestinal (GI) tr ...

- Abstract:
- ... Autophagy can restrict virus replication so efficiently that viruses have evolved means to avoid or oppose the autophagic response. Two recent studies (Ames et al. and Martin-Sancho et al.) have revealed that the autophagy receptor optineurin restricts HSV-1 replication in neurons and have elucidated how the M2 protein of IAV inhibits the completion of autophagy. ...

A new study (Shelton et al.) highlights how Salmonella manipulates the mammalian host to produce anaerobic respiratory electron acceptors, allowing catabolism of propionate and providing a competitive edge to Salmonella residing in the gut. ...
