Commentary | Host-Microbe BiologymSphere of Influence: Finding a Direction—How Do Mitochondria Know Where To Go?Lena Pernas works in the field of metabolism of infection. In this mSphere of Influence article, she reflects on how work by Brian Cunniff (B. Cunniff, A. J. McKenzie, N. H. Heintz, and A. K. Howe, Mol Biol Cell 27:2662–2674, 2016, https://doi.org/10.1091/mbc.e16-05-0286) and Thomas Schwarz (G. Pekkurnaz, J. C. Trinidad, X. Wang, D. Kong, and T. L. Schwarz, Cell 158:54–68, 2014,...
Research Article | Host-Microbe BiologyMonoclonal Antibodies to Intracellular Stages of Cryptosporidium parvum Define Life Cycle Progression In VitroCryptosporidium is a protozoan parasite that causes gastrointestinal disease in humans and animals. Currently, there is a limited array of antibodies available against the parasite, which hinders imaging studies and makes it difficult to visualize the parasite life cycle in different culture systems. In order to alleviate this reagent gap, we created a library of novel antibodies against the intracellular life cycle stages of...
Research Article | Host-Microbe BiologyDeep Sequencing of RNA from Blood and Oral Swab Samples Reveals the Presence of Nucleic Acid from a Number of Pathogens in Patients with Acute Ebola Virus Disease and Is Consistent with Bacterial Translocation across the GutOur results highlight the identification of an array of pathogens in the blood of patients with Ebola virus disease (EVD). This has not been done before, and the data have important implications for the treatment of patients with EVD, particularly considering antibiotic stewardship. We show that EVD patients who were also infected with Plasmodium, particularly at higher loads, had more adverse outcomes than patients with lower...
Research Article | Host-Microbe BiologyToxoplasma gondii AP2IX-4 Regulates Gene Expression during Bradyzoite DevelopmentToxoplasma gondii is a single-celled parasite that persists in its host as a transmissible tissue cyst. How the parasite converts from its replicative form to the bradyzoites housed in tissue cysts is not well understood, but the process clearly involves changes in gene expression. Here we report that parasites lacking a cell cycle-regulated transcription factor...
