Oesophagostomum radiatum: The nodular worm infection in calves and larval recovery from nodules
Sudhakar Kommu, GS Sreenivasa Murthy and G Rajeshwari
The pathogenic effect of Oesophagostomum radiatum in cattle is attributed to the nodules in the intestine and it is the most damaging worm to cattle when present in large number. Repeated exposure to the infective larvae may result in the accumulation of large numbers of fourth stage worms in nodules. The calf intestines having nodules were collected and processed both by acid pepsin method and by pressing the nodules in between two slides. Both of the procedures revealed the presence of larvae which lateron was confirmed to be fourth stage (L4) male larvae based on the its morphological characters such as presence of buccal capsule; the size of the tail which is generally short, dorsally directed and ended abruptly with a ventral truncation.
