Blattabacterium cuenoti is a bacterial species of the Bacteroidetes . It is the only species in the Blattabacteriaceae family . The species forms a symbiosis with cockroaches and a termite species and was only found within these insects .

Appearance

The cells are either straight or slightly curved rods with rounded ends. The diameter is 1 µm and the length is between 1.6 and 9.0 µm. The length varies a little depending on the type of cockroach. Within cells of the cockroach's abdomen , the bacteria are present in specialized cells called mycetocytes. Here they are slightly longer than in cells within the gonads and embryos of insects.

ecologist

Blattabacterium cuenoti forms a symbiosis with the termite species Mastotermes darwiniensis and with almost all cockroach species. Within the genus scraping Nocticola was Blattabacterium not yet been found. The bacterium is vital for the insects. It is an intracellular symbiont (within cells of the host) and inhabits cells in the abdomen. Blattabacterium cuenoti supplies certain amino acids . It also forms reusable nitrogen compounds from the uric acid formed by the host . So far it has not been possible to cultivate Blattabacterium outside the host.
