Isolated in 1991 by Carlos E. Winter in soil samples taken at the University of Sao Paulo in Brazil. Hermaphrodite strain. Adults are smaller than C. elegans. 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.
