  The gut microbiota influences many infectious diseases; however, its role Leptospirosis remains unclear. In this fundamental work, Xie et al. use a hamster model to show that Leptospira infection leads to gut pathology, an altered gut microbiota, and increased translocation. A combined use of antibiotics and LPS neutralization prolonged survival, providing a potential new therapeutic approach. This study utilizes compelling methods to provide new insights into this emerging disease, which could be dissected further in future studies aimed at gaining mechanistic insight and assessing the translational relevance of these discoveries.

  This important work identifies a p. aeruginosa strain and enzyme that can degrade 1-naphthylamine, a harmful industrial pollutant. Data resulting from in vivo and structural approaches are compelling, but additional mutagenesis would further test and establish the broad substrate specificity of NpaA1. With this additional data, this paper would be of high interest to biologists and enzymologists studying biodegradation of industrial pollutants.

A chemically induced attenuated strain of Candida albicans generates robust protective immune responses and prevents systemic candidiasis development

  This study presents a useful strategy in which the authors devised a simple method to attenuate Candida albicans and deliver a live whole-cell vaccine in a mouse model of systemic candidiasis. The reviewers are not convinced about the completeness of the study: the strength of the evidence is incomplete and could be augmented with additional experiments to more fully characterize vaccine efficacy and host immune responses.

  Wounds are commonly infected, which can lead to delayed or poor wound healing, thereby significantly impacting morbidity and overall quality of life for patients. This manuscript uses single cell RNA sequencing to try to understand the impact of infection on various cell types during wound healing in a mouse model. The methodology is solid and the results provide a valuable 'atlas' of the cellular changes associated with infected and uninfected wounds which will be of interest to the field.

  This study provides valuable insights into how chromatin-bound PfMORC controls gene expression in the asexual blood stage of Plasmodium falciparum. By interacting with key nuclear proteins, PfMORC is predicted to affect expression of genes relating to host invasion and variable subtelomeric gene families. Correlating transcriptomic data with in vivo chromatin analysis, the study provides convincing evidence for the role of PfMORC in epigenetic transcriptional regulation.
