The effects of single and multiple doses of thiabendazole on growing and arrested stages of the rabbit stomach worm Obeliscoides cuniculi

Preliminary observations, using 5 rabbits carrying long-standing infections, indicated that single doses of thiabendazole were effective against adult O. cuniculi and that repeated doses may have had some effect on arrested larvae. A multiple dosing regime, consisting of 1 dose at 110 mg kg −1 body weight followed by 8 doses at 70 mg kg −1 body weight at 4-h intervals, was successful in removing 99.12% of developing worms and 86.04% of arrested larvae.
