Editor's Pick Research Article | Host-Microbe BiologyCandida auris Forms High-Burden Biofilms in Skin Niche Conditions and on Porcine SkinThe emerging fungal pathogen Candida auris causes invasive infections and is spreading in hospitals worldwide. Why this species exhibits the capacity to transfer efficiently among patients is unknown. Our findings reveal that C. auris forms high-burden biofilms in conditions mimicking sweat on the...
Commentary | Host-Microbe BiologyCandida auris Biofilm Colonization on Skin Niche ConditionsCandida auris, an emerging multidrug-resistant yeast, has recently been associated with outbreaks of invasive infections in health care facilities worldwide. Its success as a nosocomial pathogen lies in its capability to sustain for prolonged periods in the intensive care unit (ICU), adeptly colonize skin, and spread among patients. Little is known of the mechanism...
Commentary | Host-Microbe BiologymSphere of Influence: the Mycobiota in Human Health and DiseaseSoo Chan Lee works in the field of medical mycology. In this mSphere of Influence article, he reflects on how “Interactions between commensal fungi and the C-type lectin receptor Dectin-1 influence colitis” (Science 336:1314–1317, 2012, https://doi.org/10.1126/science.1221789) by I. D. Iliev, V. A. Funari, K. D. Taylor, Q.
Research Article | Host-Microbe BiologyLinking Sfl1 Regulation of Hyphal Development to Stress Response Kinases in Candida albicansCandida albicans is a commensal as well as a pathogen of humans. C. albicans is able to mount a cellular response to a diverse range of external stimuli in the host and switch reversibly between the yeast and hyphal growth forms. Hyphal development is a key virulence determinant. Here, we studied...
Commentary | Host-Microbe BiologymSphere of Influence: Positive Research Culture Enables Excellence and InnovationElizabeth Ballou works in the field of medical mycology. In this mSphere of Influence article, she reflects on how two papers by Okagaki et al. (PLoS Pathog 6:e1000953, 2010, https://doi.org/10.1371/journal.ppat.1000953) and Zaragoza et al. (PLoS Pathog 6:e1000945, 2010, https://doi.org/10.1371/journal.ppat.1000945) made...
Commentary | Host-Microbe BiologymSphere of Influence: It’s Not Me, It’s You—How Donor Factors Influence Kidney Transplant OutcomesDiana V. Pastrana works in the field of DNA tumor virus biology. In this mSphere of Influence article, she reflects on how the two papers “Donor origin of BKV replication after kidney transplantation” (C. Schmitt, L. Raggub, S. Linnenweber-Held, O. Adams, et al., J Clin Virol 59:120–125, 2014, https://doi.org/10.1016/j.jcv.2013.11.009) and “Neutralizing antibody-mediated response...
Research Article | Host-Microbe BiologyCampylobacter Abundance in Breastfed Infants and Identification of a New Species in the Global Enterics Multicenter StudyCampylobacter is the primary cause of bacterial diarrhea in the United States and can lead to the development of the postinfectious autoimmune neuropathy known as Guillain-Barré syndrome. Also, drug-resistant campylobacters are becoming a serious concern both locally and abroad. In low- and middle-income countries (LMICs), infection with Campylobacter is linked to high rates of morbidity, growth stunting, and mortality...
Research Article | Host-Microbe BiologyDual and Triple Epithelial Coculture Model Systems with Donor-Derived Microbiota and THP-1 Macrophages To Mimic Host-Microbe Interactions in the Human Sinonasal CavitiesDespite the relevance of the resident microbiota in sinonasal health and disease and the need for cross talk between immune and epithelial cells in the upper respiratory tract, these parameters have not been combined in a single in vitro model system. We have developed a coculture system of differentiated respiratory epithelium and natural nasal microbiota and incorporated an immune component. As indicated by absence of...
Opinion/Hypothesis | Host-Microbe BiologyPotential of Chemically Synthesized Oligosaccharides To Define the Carbohydrate Moieties of the Fungal Cell Wall Responsible for the Human Immune Response, Using Aspergillus fumigatus Galactomannan as a ModelMethodologies to identify epitopes or ligands of the fungal cell wall polysaccharides influencing the immune response of human pathogens have to date been imperfect. Using the galactomannan (GM) of Aspergillus fumigatus as a model, we have shown that synthetic oligosaccharides of distinct structures representing key fragments of cell wall polysaccharides are the most...
Observation | Host-Microbe BiologyInfluence of Plasmodium falciparum Calcium-Dependent Protein Kinase 5 (PfCDPK5) on the Late Schizont Stage PhosphoproteomeThe malaria parasite Plasmodium falciparum is a major cause of morbidity and mortality globally. The P. falciparum parasite proliferates inside red blood cells during the blood stage of infection, and egress from the red blood cell is critical for parasite survival....
