Alistipes is a genus of bacteria. The type species is Alistipes putredinis .
Appearance
The cells are straight or slightly curved rods. The diameter is 0.2 to 0.9 µm, the length 0.5 to 4 µm. The gram test is negative. You are not agile . Spores are not formed. The cells usually appear alone or in pairs. In alistipes finegoldii even longer filaments may occur. Alistipes is mandatory anaerobic . With the exception of Alistipes putredinis , the catalase test is positive for all species .
Growth and metabolism
Optimal growth is seen at 37 ° C. Alistipes is chemo-organotrophic . The metabolism is fermentation . The products are succinyl acid (succinic acid) and small amounts of acetic acid . The Alistipes putredinis species is saccharolytic, which means that it is able to digest carbohydrates and does not produce pigment .
Occurrence
Alistipes occurs in the intestines of humans and animals. It is rarely pathogenic , as has been demonstrated in infections of the abdominal cavity .
