Strain: CEW1
   Genotype: Oscheius species.
Description: 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.  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.
