Caenorhabditis brenneri

C. brenneri is a small, free-living round worm found in decaying plant material throughout the tropics. The worms feed on the bacteria and other microorganisms associated with plant decay. The biology of C. brenneri is similar to that of C. elegans with a short generation time through four larval stages into an adult. C.brenneri has both male and female adults unlike the hermaphroditic species such as C. elegans and C. briggsae.

C. brenneri has previously been known as Caenorhabditis n. sp. 4 or PB2801 prior to the type description and renaming in 2007 (Sudhaus & Kiontke). The sequenced strain PB2801 was derived from a wild isolate LKC28 isolated by Hernan Ruiz from the roots of Liriope (Convallariaceae) in 2003 grown in an Costa Rican nursery. The wild isolate was inbred for 20 generations in the lab of Scott Baird by transferral of a single gravid female per generation.
