Isolated in Memorial Park in Madison, WI. No hermaphrodites. Lots of SDS resistant dauers. Can survive between 15-28C, but grows very slowly at 15C.

Isolated in Towers Hill State Park in WI. Males are rare. No SDS resistant dauers. Animals are osmosensitive, can be dried competely and recover in water. Rhabditidae. Previously known as Rhabditis sp.

Isolated in 1991 by Carlos E. Winter in soil samples taken at the University of Sao Paulo in Brazil. Hermaphrodite strain. Adults are 1.5mm. The life cycle is a little longer than C. elegans at 22C. Each lays about 300 eggs in the three days following the moult from L4 to adult. Eggs are laid just after being fertilized resulting sometimes in plates with many eggs (much more than C. elegans). See Comp. Biochem. Physiol 103B: 189, 1992. See Nematology 2(1): 89-98, 2000. Can be grown and maintained on NGM. L1s easily frozen and stored in liquid nitrogen. This strain is deposited in Paul Sternberg's collection under the name PS1022. The species has not yet been determined; Lynn Carta will publish a paper proposing Oscheius brevesophaga. DO NOT use this name before the paper is published. Contact Carles E. Winter or Lynn Carta before publishing anything official about this strain. See also WBPaper00004471 and WBPaper00004485. AKA Oscheius sp. 1.

WT strain. Rhabditis (Oscheius) dolichuroides. Isolated by W. Sudhaus in April 1978 from decaying matter in a hole in a tree in Malindi, Kenya. See WBG 12(5) 14. Male/Female strain.

0020. Formerly known as Rhabditis (Rhabditis) myriophila. Taxonomy ID: 281680 Isolated by G. O. Poiner (see Poiner, 1986).

WT strain. Oscheius sp. See WBG 12(5) 14. Male/Female strain. Collected by a Belgian expedition to the Galapagos archipelago. From Gaetan Borgonie, Gent University, Belgium.

WT strain. Isolated by D. Fitch in June 1990 from soil in Scott Emmons' compost heap in the Fort Greene section of Brooklyn, NY. A second strain, DF5038, was isolated from the same location one year later from the head and ventral segments of a male pill bug (Armadillidium vulgare). Hermaphroditic. Males are easily isolated by heat shocking L4 or early adult hermaphrodites at 30C for 6-12 hrs. Grows well at 6-25C on OP50. Dauer larvae accumulate under starved or overcrowded conditions. Freezes easily using C. elegans protocols with 90% viability. Previously called Rhabditis sp. See also WBPaper00003418. Formerly known as Oscheius myriophila.
