متن کاملCryopreservation of Infective Third-Stage Larvae of Trichostrongylus axei and T. colubriformis
Trichostrongylus axei and T. colubriformis infective third-stage larvae were frozen and stored for varying periods at -170 C: 10 to 80 days for T. axei and 10 to 38 days for T. colubriformis. Thawed, surviving larvae were used to infect rabbits. Survival percentages changed little between worms stored for the period of the test. Larvae surviving freezing, storage, and thawing were as infective ...

متن کاملTrichostrongylus colubriformis: relationship between ageing of infective larvae, infectivity and egg production by adult female worms.
Relationships between egg production and infectivity were studied with infective larvae of Trichostrongylus colubriformis which had been stored for up to 22 weeks at 24 degrees C. After different storage times, larvae were administered to lambs and the number of parasites which reached the adult stage was counted five weeks after infection. Egg production was estimated for the same batches of a...
متن کاملIntraspecific Epitopic Variation in a Carbohydrate Antigen Exposed on the Surface of Trichostrongylus colubriformis Infective L3 Larvae
The carbohydrate larval antigen, CarLA, is present on the exposed surface of all strongylid nematode infective L3 larvae tested, and antibodies against CarLA can promote rapid immune rejection of incoming Trichostrongylus colubriformis larvae in sheep. A library of ovine recombinant single chain Fv (scFv) antibody fragments, displayed on phage, was prepared from B cell mRNA of field-immune shee...
