The Capnocytophaga are a genus of bacteria . It belongs to the Flavobacteriaceae family . The type species is Capnocytophaga ochracea .

Appearance

The cells are short or long and fusiform in shape; that is, they are lanceolate or spindle-shaped and have pointed ends. Rod-shaped cells also appear. The cells can also occasionally appear helically wound. The diameter is in the range from 0.42 to 0.6 µm, the length is between 2.5 and 5.7 µm. Filaments can also be formed, i.e. coherent, elongated individual cells. The cells can be pleomorphic . The Gram test is negative, the bacteria are gram- negative. The movement is smooth. The optimal growth temperature is between 35 and 37 ° C.

Growth and metabolism

The genus Capnocytophaga is facultatively anaerobic. The species are capnophilic ("carbon dioxide-loving"), for growth in air (ie aerobic growth) they need a CO₂ content of 5%. Capnocytophaga is chemo-organotrophic , the metabolic type is fermentation . Carbohydrates are fermented; is glucose used, produced as end products mainly acetate and succinate .

ecology

The species Capnocytophaga gingivalis , C. ochracea , C. sputigena , C. granulosa and C. haemolytica are found in the oral flora of humans, Capnocytophaga canimorsus and C. cynodegmi in the oral flora of dogs and cats. The pathogenicity in humans is uncertain, but cases involving species of Capnocytophaga have been reported .
