Zeldia punctata (Thorne, 1925) Thorne, 1937

CGC strain code:


Other codes:

alphaD, WCUG3, JB-040


Nebe, central Senegal: Sahel soil 5 km south of Diourbel along road Diourbel-Gossas. Collected in August 1991 by Pierre Baujard.


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.


Freely available on agar.

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.
