Chronic obstructive pulmonary disease (COPD) is an inflammatory disorder characterized by incompletely reversible airflow obstruction. Bacterial infection of the lower respiratory tract contributes to approximately 50% of COPD exacerbations. Even during periods of stable lung function, the lung harbors a community of bacteria, termed the microbiome. The role of the lung microbiome in the pathogenesis of COPD remains unknown. The COPD lung microbiome, like the healthy lung microbiome, appears to reflect microaspiration of oral microflora. Here we describe the COPD lung microbiome of 22 patients with Moderate or Severe COPD compared to 10 healthy control patients. The composition of the lung microbiomes was determined using 454 pyrosequencing of 16S rDNA found in bronchoalveolar lavage fluid. Sequences were analyzed using mothur, Ribosomal Database Project, Fast UniFrac, and Metastats. Our results showed a significant increase in microbial diversity with the development of COPD. The main phyla in all samples were Actinobacteria, Firmicutes, and Proteobacteria. Principal coordinate analyses demonstrated separation of control and COPD samples, but samples did not cluster based on disease severity. However, samples did cluster based on the use of inhaled corticosteroids and inhaled bronchodilators. Metastats analyses demonstrated an increased abundance of several oral bacteria in COPD samples.

“…Strains belonging to other species in the genus Dysgonomonas were isolated from human clinical specimens (Hofstad et al, 2000;Lawson et al, 2002Lawson et al, , 2010, while strain Dy73 T was isolated from a CE-MFC bioreactor with paddy field soil as the inoculum. In addition to habitats, other distinguishing features include 16S rRNA gene sequence, DNA G+C content, bile resistance, substrate utilization patterns and fatty-acid composition.…”

“…This strain was isolated from a human clinical specimen of an abdominal drain (Lawson et al, 2002). The second closest relative was Dysgonomonas gadei CCUG 42882 T (94.3 %) isolated from an infected human gall bladder (Hofstad et al, 2000), and the third and fourth were Dysgonomonas hofstadii CCUG 54731 T (92.8 %) isolated from a human clinical sample of a postoperative abdominal wound (Lawson et al, 2010) and Dysgonomonas capnocytophagoides CCUG 17996 T (91.5 %) isolated from a human clinical specimen (Hofstad et al, 2000). In addition to these isolates, strain Dy73 T showed 16S rRNA gene sequence similarity to some uncultured bacterial clones that were retrieved from MFC reactors inoculated with activated sludge, domestic wastewater, or anaerobic digester slurry; these included GG8 (GenBank accession no.…”

A Gram-stain-negative, non-motile and coccoid-to short-rod-shaped bacterium, designated strain Dy73 T , was isolated from a microbial fuel cell that had been inoculated with rice paddy field soil and fed starch, peptone and fish extract as fuels. On the basis of 16S rRNA gene sequence phylogeny, strain Dy73 T was affiliated with the genus Dysgonomonas in the phylum Bacteroidetes, and most closely related to Dysgonomonas mossii CCUG 43457 T with a 16S rRNA gene sequence similarity value of 99.7 %. However, the DNA-DNA relatedness value between strain Dy73 T and Dysgonomonas mossii CCUG 43457 T was 34.8 %. In addition, strain Dy73 T was found to be different from other recognized species of the genus Dysgonomonas in taxonomically important traits, including habitat, DNA G+C content, bile resistance and fatty-acid composition. Based on these characteristics, strain Dy73 T represents a novel species of the genus Dysgonomonas for which the name Dysgonomonas oryzarvi sp. nov. is proposed. The type strain is Dy73 T (5JCM 16859 T 5KCTC 5936 T ).
