Corynebacterium uropygiale is an actinobacterium of the genus Corynebacterium , which so far has onlybeen detected in the rump glands (Latin: Glandula uropygialis ) of turkeys ( Meleagris gallopavo ), where it belongs to the natural microbiome . Although bacteria - including corynebacteria - are often found on birds, C. uropygiale has been a constant since it was re-described in 2016 by Braun et al. the only representative of its genus so far, whose habitat is the rump gland.

General properties

Corynebacterium uropygiale is a club-shaped Gram-positive rod, which is often arranged in palisades or V-formations. They are non -acid-fast , non- spore-forming facultative anaerobes . As with most Corynebacteria, the cell wall of C. uropygiale contains mycolic acids . The G + C content of the type strain is 60.7 mol% in the. The closest relative of the species is also found on individuals of the class of birds : In 2003, Corynebacterium spheniscorum was identified by Goyache et al. (2003 ) isolated from Magellanic penguins ( Spheniscus magellanicus ).

Cultivation

Corynebacterium uropygiale grows on complex media that contain monounsaturated fatty acids, such as B. Tween-80 included. Good growth is recorded on such agar media after incubation at 37 ° C for 48 hours. However, the bacterium grows poorly on Columbia agar with 5% sheep blood. C. uropygiale does not grow on media such as Lysogeny Broth , Tryptic Soy Agar or Müller-Hinton Agar .

Lipophilicity

C. uropygiale is able to reproduce in a lipid-rich environment such as the uterine gland. Instead of using energy to produce the necessary fatty acids itself, it uses substances from the rump gland secretion. This can be seen as an evolutionary adaptation to the habitat , because the energy saved as a result can now be used for other metabolic processes , resulting in a potential increase in biological fitness .
