The two Hong Kong strains were isolated from a 48-year-old man with intestinal obstruction and secondary sepsis (strain HKU16<jats:sup>T<\/jats:sup>) and from a 39-year-old man with acute appendicitis (strain HKU17), while the two Canadian strains were isolated from a 74-year-old man with biliary sepsis (strain CA1) and from a 66-year-old woman with metastatic carcinoma and sepsis (strain CA2). While the first three patients survived, the last patient died 2 weeks after the episode of bacteremia. All four isolates are strictly anaerobic, nonsporulating, gram-positive coccobacilli that were unidentified by conventional phenotypic tests and commercial identification systems. They grow on sheep blood agar as nonhemolytic pinpoint colonies after 48 h of incubation at 37\u00b0C in an anaerobic environment. All are catalase positive and motile, with flagella. They produce acid from arabinose, glucose, mannose, and xylose. They do not produce indole or reduce nitrate. They are sensitive to penicillin, vancomycin, and metronidazole but resistant to cefotaxime. 16S rRNA gene sequence analysis showed 16.0%, 16.8%, and 21.0% base differences from<jats:italic>Clostridium propionicum<\/jats:italic>,<jats:italic>Clostridium neopropionicum<\/jats:italic>, and<jats:italic>Atopobium minutum<\/jats:italic>, respectively. The G+C content of strain HKU16<jats:sup>T<\/jats:sup>is 40.2% \u00b1 2.2%. Based on their phylogenetic affiliation, unique G+C content, and phenotypic characteristics, we propose a new genus and species,<jats:italic>Catabacter hongkongensis<\/jats:italic>gen. nov., sp. nov., to describe the bacterium, for which HKU16 is the type strain, and suggest that it be assigned to a new family,<jats:italic>Catabacteriaceae<\/jats:italic>. The gastrointestinal tract was probably the source of the bacterium for at least three of the four patients. The isolation of a catalase-positive, motile, nonsporulating, anaerobic gram-positive bacillus in clinical laboratories should raise the possibility of<jats:italic>C. hongkongensis.<\/jats:italic>Further studies should be performed to ascertain the epidemiology and other disease associations of this bacterium.<\/jats:p>","DOI":"10.1128\/jcm.01831-06","type":"journal-article","created":{"date-parts":[[2006,11,23]],"date-time":"2006-11-23T01:54:00Z","timestamp":1164246840000},"page":"395-401","update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":60,"title":["<i>Catabacter hongkongensis<\/i>gen. nov., sp. nov., Isolated from Blood Cultures of Patients from Hong Kong and Canada"],"prefix":"10.1128","volume":"45","author":[{"given":"Susanna K.
