Fatal trichuris spp. infection in a Holstein heifer persistently infected with bovine viral diarrhea virus.
Whipworms (Trichuris spp.) were identified in the colon of a recently purchased, 10-month-old dairy heifer that died suddenly. A skin test was positive for bovine viral diarrhea virus (BVDV). Signs of BVDV occurred in other heifers in the group, but fecal flotations were negative for whipworm eggs.
