Researcher Ali Ashare Publishes Paper in PLoS ONE
The paper, Throat Swabs and Sputum Culture as Predictors of P. aeruginosa or S. aureus Lung Colonization in Adult Cystic Fibrosis Patients, which was recently published in PLoS ONE, investigates the utility of throat swab cultures in detecting the most common CF pathogens. Dr. Alix Ashare, along with Pulmonary Fellow Dr. Darius Seidler and other Lung Biology Center colleauges, compared culture results of two of the most common CF pathogens obtained from throat swabs, sputum, and bronchoalveolar lavage fluid obtained from adult patients with CF. Their work demonstrates that the positive predictive value of P. aeruginosa when found on throat swab is excellent, but S. aureus on throat swab was not a good predictor of S. aureus in the lung. These data suggest that throat culture results in adult patients with CF need to be interpreted within the clinical context and may not reflect colonization of the lung.
Researcher Robert Cramer Publishes Paper in ASM Journal mBio
The paper, Heterogeneity among Isolates Reveals that Fitness in Low Oxygen Correlates with Aspergillus fumigatus Virulence, recently published in the ASM journal mBio, highlights the role of intraspecies heterogeneity in the important pulmonary fungal pathogen Aspergillus fumigatus in the specific host context of corticosteroid-mediated immune suppression. Dr. Robert Cramer, and his students and colleagues, report that A. fumigatus virulence, specifically in this host context, varies across clinical and environmental isolates, and that this variation correlates significantly with the ability of the strains to thrive in low oxygen (hypoxia), a known and prominent feature of the in vivo host microenvironment in this model. An experimental evolution approach through hypoxic conditions was utilized to illustrate this relationship between hypoxic fitness and virulence in this pathogen, and the authors' work to identify the precise causative mechanisms coordinating this relationship remain ongoing. Importantly, this report highlights the existence of clinically-relevant heterogeneity within the single pathogenic fungal species A. fumigatus, and further emphasizes the noteworthy differences in fungal virulence across different host contexts.
New COBRE Award for Biomolecular Targeting
Dartmouth has received a five-year, $12.5M National Institutes of Health (NIH) award to establish a new COBRE Institute for Biomolecular Targeting. The Institute is led by Lung Biology Center faculty members Dr. Dean Madden (PI/Director) and Dr. Deborah Hogan (Associate Director). The proposal highlighted four junior-faculty research programs focused on discovery and early-stage translational studies to identify new molecular targets for cancer, inflammation, and viral airway infections. The inflammation studies, spearheaded by Translational Research Core Co-Director Dr. Alix Ashare, have already received independent NIH funding. iTarget also funds shared scientific resources for producing molecular tools (proteins and small molecules) and for analyzing their interactions in vitro and in cells. The Institute also coordinates programs for mentoring, training, and pilot studies. It joins an interactive group of COBRE and INBRE Programs at Dartmouth and across the region. Dartmouth News story.

New Machine-Learning Technique Can be Applied to Study of Pseudomonas aeruginosa
There are now vast quantities of data that are uploaded and made available but rarely used. A collaboration between Deborah Hogan, Associate Professor in Microbiology and Immunology and Dartmouth Lung Biology Center Researcher and Casey Greene, Assistant Professor at the University of Pennsylvania and a former Dartmouth Lung Biology Center Researcher, developed a method to make these data useful to researchers. Their application of this method to the study of Pseudomonas aeruginosa, a major challenge for individuals with Cystic Fibrosis, has been published in the journal mSystems. For more information, see Penn Medicine News Release and the paper ADAGE-Based Integration of Publicly Available Pseudomonas aeruginosa Gene Expression Data with Denoising Autoencoders Illuminates Microbe-Host Interactions.
A Microbiome is Borne - Science Friday
"A baby in the womb is protected from most microorganisms. But when that baby enters the outside world, it's greeted by a welcoming committee of bacteria. Now, researchers are trying to sort out what effect factors like an infant's delivery method and early diet have on its community of microorganisms. Juliette Madan and Anne Hoen, two authors of a paper published recently in the journal JAMA Pediatrics, say that developing a better understanding of the infant microbiome could one day lead to healthier babies."
