Abstract

Escherichia coli tagged with radiophosphorus was incorporated with faecal cultures containing eggs of Cooperia oncophora, Ostertagia ostertagi, and Trichostrongylus axei. The resulting infective larvae from such cultures did not exhibit any radioactivity, although it was expected that the...

There was no evidence that Haemonchus sp. and Oesophagostomum...

Abstract

Bayer 21/199, (XO-diethyl O-(3-chloro-4-methyl-7-coumarinyl) phosphorothioate, was tested for anthelmintic activity in cattle and sheep. Tests indicated that, when administered at 25 mg./kg. live wt., it was highly efficient against species of the genera Haemonchus, Ostertagia, Trichostrongylus,...

Abstract

A high proportion of parasitic larvae present in cattle at the end of a period of grazing persisted as larval forms for an additional period of 28 days after the animals were transferred to a barn. The great majority of fourth-stage larvae recovered at necropsy from eight animals after barn...
