  In this important study, the authors advance our understanding of copper uptake by chalkophores and their targeted metalloproteins in Mycobacterium tuberculosis. These convincing data demonstrate that chalkophore-acquired copper is solely incorporated into the Mtb bcc:aa3 copper-iron respiratory oxidase under low copper conditions, and that chalkophore-mediated protection of the respiratory chain is critical to Mtb virulence. These findings may be leveraged for drug discovery and will be of broad interest to those studying bacterial pathogenesis.

  This important work attempts to understand observed variability in oral shedding of SARS-CoV-2 and suggests that routine clinical factors are not determinative. The evidence supporting the conclusion is solid though the limited clinical heterogeneity of the included cohorts, the lack of COVID vaccination, and the absence of comprehensive viral load data for model training, makes the results difficult to generalize to contemporaneous COVID-19 conditions. This study may be of interest to virologists, public health officials and clinicians.

Apparent cooperativity between human CMV virions introduces errors in conventional methods of calculating multiplicity of infection

  eLife Assessment

  The authors combine experiments and mathematical modeling to determine how the infectivity of human cytomegalovirus scales with the viral concentration in the inoculum, i.e., considering the multiplicity of infection (MOI). They propose and test different model assumptions to explain a mechanism termed "apparent cooperativity" of virions based on an observed super-linear increase in the number of infected cells with increasing inocula. The authors present a solid study showing valuable findings for virologists and quantitative scientists working on the analysis and interpretation of viral infection dynamics. Some of the presented aspects would benefit from additional clarification.

  This study presents a role for heparin sulfate in SARS-CoV-2 entry that runs counter to prevailing data in the field. If the conclusions were firmly supported by the data, the work would be a significant contribution to the field. While the use of diverse cellular models, virological tools, and robust microscopy approaches constitutes a useful data set, the proposed model remains incomplete and requires clarification of entry mechanisms, host factors, and viral variant-specific fusion pathways to substantiate it against established entry models.

  Using a transposon sequencing (TN-seq) approach, the authors identified key genetic determinants of drug tolerance in Mycobacterium abscessus. Given that M. abscessus is inherently resistant to multiple antibiotics, this valuable study makes a significant contribution by uncovering how antibiotic tolerance is linked to reactive oxygen species (ROS) in this non-tuberculous mycobacterial (NTM) species. The solid findings further strengthen the growing evidence that ROS play a central role in the mechanism of antibiotic action and tolerance in mycobacteria. However, the manuscript would benefit from improved clarity of presentation and corrections in the reference section.

  The authors identify a novel, conserved link between glycolytic flux and sulfur amino acid metabolism that governs fungal morphological differentiation independently of the cAMP-PKA pathway. This represents an important conceptual advance in understanding metabolic control of development and virulence. While the evidence supporting this connection is compelling, the mechanistic basis of how glycolysis regulates the Met30/Met4 axis requires further experimental clarification.
