  The valuable study by Dumeaux et al examines the transcriptional response to antifungal treatment in the major opportunistic human fungal pathogen Candida albicans. Using solid methodology, including a novel droplet-based single cell transcriptomics platform, the authors report that fungal cells exhibit heterogeneity in their transcriptional response to antifungal drug treatment. The ability to study the trajectories of individual cells in a high-throughput manner provides a novel perspective on studying the emergence of drug tolerance and resistance in fungal pathogens.

  This is a valuable addition to the literature as it helps us understand the role of tRNA modifying enzymes in Mycobacterium tuberculosis. By knocking out one of the enzymes, the authors convincingly demonstrate the importance of tRNA-modifying enzymes for intra-host growth of tubercle bacteria. Some of the claims regarding modification as well as the role in virulence could be strengthened through further bioinformatics and phylogenetic analyses as well as experimental approaches. The work will be of interest to microbiologists.

  Resistance of Plasmodium falciparum to artemisinin, which has become a threat to malaria control, has been linked to mutations in the parasite protein K13. This study provides important new insights into the function of K13 in the endocytosis of hemoglobin, a central process for the activation of artemisinin derivatives. Conditional protein mislocalization combined with high-resolution imaging provides convincing evidence that K13 is involved in the formation of cytostomes, the structures involved in the endocytosis of host cytosol. This study will be of interest to scientists working on parasite biology as well as antimalarial drug resistance.
