Cardiobacteriaceae

Cardiobacterium hominis on blood agar

  • Cardiobacterium
  • Dichelobacter
  • Suttonella

Cardiobacteriaceae form a family of Proteobacteria and are the only member of the order Cardiobacteriales. It is in gram- negative facultative anaerobic bacteria. The genus Dichelobacter but seems less to tolerate oxygen well. The rod-shaped cells usually appear in pairs or chains. Also the formation of rosettes may occur. You have pili but no flagella. The pili are type IV pili (N- methylphenylalanine pilus - class ), bacteria that can have this type of pili is " twitching " move on solid ground. Growth in media is rather slow. Dichelobacter except for the pathway of all types is by fermentation ( fermentation with the presence of oxygen). You are chemoorganotroph, they require organic substances such as glucose to the diet.

Characteristics of each species

Cardiobacterium: The first description of Cardiobacterium probably occurred in the examination of endocarditis ( endocarditis ) in 1962, which identified not even closer to the genus Pasteurella similar ( Pasteurella -like) isolated bacterium was first by the Centers for Disease Control and Prevention to " Group II D asked " and in 1964 finally called Cardiobacterium hominis. This bacterium is pleomorphic. As Suttonella the cells are rod-shaped with rounded ends. C. hominis seems a harmless inhabitant of the Nasensraum of people to be, but in rare cases, the causative agent of bacterial endocarditis.

Dichelobacter: This bacterium is the causative agent of foot rot (also called Schafpanaritium ) in sheep. It is regarded as obligate anaerobes, but it also increases at a time more oxygen. The cells are long, straight or slightly curved rods.

Suttonella: The long, straight rod-shaped cells of Suttonella have rounded ends. Little is known about the bacteria as pathogen, it has been found in eye infections, and however, in endocarditis.

System

On the basis of 16S rRNA analysis and the GC - content is provided to the family Kingella indologenes Cardiobacteriaceae of the family Neisseriaceae, Bacteroides nodosus, and in Suttonella indologenes ( Bacteroidaceae ) Dichelobacter nodosus and renamed with Cardiobacterium hominis.

This family consists of the following genera and species:

  • Cardiobacterium Slotnick and Dougherty 1964 Cardiobacterium hominis Slotnick and Dougherty 1964
  • Cardiobacterium valvarum Han et al. 2004 emend. Han and Falsen 2005
  • Dichelobacter Dewhirst et. al, 1990 Dichelobacter nodosus ( Beveridge 1941) Dewhirst et al. 1990
  • Suttonella ( Dewhirst et al., 1990) Suttonella indologenes ( Snell and Lapage 1976) Dewhirst et al. 1990
  • Suttonella ornithocola Foster et al. 2005
