Zeldia punctata (Thorne, 1925) Thorne, 1937
|
|
CGC strain code:
PDL0003
Other codes:
alphaD, WCUG3, JB-040
Locality:
Nebe, central Senegal: Sahel soil 5 km south of Diourbel along road Diourbel-Gossas.
Collected in August 1991 by Pierre Baujard.
Classification:
Secernentea - Rhabditida - Cephalobina - Cephaloboidea - Cephalobidae
Culture conditions:
Xenic: E. coli on 1.5% pure agar (with or without 0.1% NA) + 5 µg/ml
cholesterol. Currently kept on "wet plates" (1% agar + cholesterol + 5
ml 0.05M phosphate buffer at pH 7.3 + E. coli). No attempts to remove
other bacteria have so far been made.
Long-term storage:
No survival after freezing in glycerin. Z. punctata can be stored
6-12 months on slowly desiccated plates. Dry slivers of such plates can
be stored permanently by freezing them at -80°C. However, it is difficult
in practice to achieve gradual desiccation of sufficient numbers of worms
to guarantee proper recovery. Always check a sliver of the desiccated plate
for recovery, both before and after freezing at -80°C.
Availability:
Freely available on agar.

Notes:
Do not keep below 20°C - thrives at 34°C according to Pierre Baujard!
Parthenogenic. Multiplies moderately fast (for a cephalobid). Males not
yet observed.
