We report a novel anaerobe causing abscess in four patients at three hospitals. In the clinical specimen, bacilli were branching, Gram positive, and acid fast. The organism grew slowly and was not identified by 16S rRNA sequencing. Our findings support the description of a new genus and species of the suborder Corynebacterineae.

We announce the draft genome sequence of Clostridium sp. JC272, isolated from a sediment sample collected from marine habitats of Gujarat, India. Clostridium sp. JC272 is an obligate anaerobe and has the ability to produce antimicrobial compounds. The genome sequence indicates the strain's capability of producing small peptides (microcins), which are potential novel antibiotics.

The first case of infective endocarditis caused by the anaerobe Staphylococcus saccharolyticus is reported. The infection occurred in a previously healthy 61-year-old male with no known predisposing valvular heart disease. The patient was successfully treated with a combination of 2 g of nafcillin every 4 h and 90 mg of gentamicin every 8 h for 6 weeks.

Metronidazole- and carbapenem-resistant Bacteroides fragilis are rare in the United States. We isolated a multidrug-resistant anaerobe from the bloodstream and intraabdominal abscesses of a patient who had traveled to India. Whole-genome sequencing identified the organism as a novel Bacteroides genomospecies. Physicians should be aware of the possibility for concomitant carbapenem- and metronid...

An Edwardsiella piscicida-like species is a Gram-negative facultative anaerobe that causes disease in some fish species. In this report, we present the complete and annotated genome of isolate LADL05-105, recovered from cultured tilapia reared in Louisiana, which contains a chromosome of 4,142,037 bp and no plasmids.

We generated a high-quality draft genome sequence of Bacteroidales strain 6E, a strict anaerobe newly isolated from Japanese rice paddy field soil. The genome consists of 61 contigs, with a total size of 4,436,542 bp and mean G+C content of 45.4%. Annotation predicted 3,620 protein-coding and 54 RNA genes.

Mycobacterium tuberculosis is a facultative anaerobe and its characteristic pathological hallmark, the granuloma, exhibits hypoxia in humans and in most experimental models. Thus the host and bacillary adaptation to hypoxia is of central importance in understanding pathogenesis and thereby to derive new drug treatments and vaccines.

The draft genome sequence of Clostridium sp. Ne2 was reconstructed from a metagenome of a hydrogenogenic microbial consortium. The organism is most closely related to Clostridium magnum and is a strict anaerobe that is predicted to ferment a range of simple sugars.

Edwardsiella piscicida is a recently described Gram-negative facultative anaerobe and an important pathogen to many wild and cultured fish species worldwide. Here, we report the complete and annotated genome of E. piscicida isolate S11-285 recovered from channel catfish (Ictalurus punctatus), consisting of a chromosome of 3,923,603 bp and 1 plasmid.

Geobacter sulfurreducens, previously classified as a strict anaerobe, tolerated exposure to atmospheric oxygen for at least 24 h and grew with oxygen as the sole electron acceptor at concentrations of 10% or less in the headspace. These results help explain how Geobacter species may survive in oxic subsurface environments, being poised to rapidly take advantage of the development of anoxic cond...
