Egg output of Graphidium strigosum (Nematoda ) in low-level prime infection of rabbits.

Rabbits of Moroccan local breed were infected with larvae of G. strigosum obtained from a wild strain (100 larvae/animal) which had undergone two different durations of storage at +4 degrees C. A long storage (10 months) induced the inhibition of the larval development at a low-rate. A shorter storage of 3 months permitted the development into adults: the prepatent period was 5 weeks and the patent period lasted over 21 weeks post infection. The egg output expressed in eggs per gram was negatively correlated to the dry matter of faeces.
