Oral microbiome and hyposalivation or caries, COPD, nasal microbiome, and bacterial communities in human semen.
Human oral microbiome

Book chapter: Xerostomia and the Oral Microflora – Antoon J. M. Ligtenberg PhD, Annica Almståhl – SpringerLink

“Hyposalivation changes the oral microbiome with the most dramatic changes after radiation therapy.”

Metatranscriptomics reveals overall active bacterial composition in caries lesions – Aurea Simón-Soro – Journal of Oral Microbiology

“A mean of 4,900 sequences of the 16S rRNA gene with an average read length of 661 bp was obtained per sample, giving a comprehensive view of the active bacterial communities in caries lesions. “

Comparison of bacterial culture and 16S rRNA community profiling by clonal analysis and and pyrosequencing for the characterisation of the caries-associated microbiome – Kathrin Schulze-Schweifing – Frontiers in Microbiology

“In this study, five pairs of broad range primers targeting 16S rRNA genes were used in clonal analysis of 6 samples collected from tooth lesions involving dentine in subjects with active caries. Samples were also subjected to cultural analysis and pyrosequencing by means of the 454 platform. “

Human respiratory microbiome

Review: The potential impact of the pulmonary microbiome on immunopathogenesis of Aspergillus-related lung disease – Eva Kolwijck and Frank L. van de Veerdonk – European Journal of Immunology

“In this perspective, we review this emerging area of research and discuss the role of the microbiome in aspergillosis, role of Aspergillus in the microbiome, and the influence of the microbiome on anti-Aspergillus host defense and its role in preventing aspergillosis.”

Novosphingobium and Its Potential Role in Chronic Obstructive Pulmonary Diseases: Insights from Microbiome Studies – Alleluiah Rutebemberwa – PLOS ONE

“We sought to elucidate the presence and types of lung bacterial populations in different stages of COPD, aimed at revealing important insights into the pathobiology of the disease”

The Nasal and Sinus Microbiome in Health and Disease – Michael T. Wilson and Daniel L. Hamilos – Current Allergy and Asthma Reports

“This review will focus on recent advances in the appreciation and understanding of these relationships in terms of the upper respiratory tract, specifically the nose and paranasal sinuses.”

Bacterial Communities in Semen from Men of Infertile Couples: Metagenomic Sequencing Reveals Relationships of Seminal Microbiota to Semen Quality – Shun-Long Weng – PLOS ONE

“Ninety-six semen samples collected were examined for bacterial communities, measuring seven clinical criteria for semen quality”
