Bovine Respiratory Syncytial Virus
(NY) Bovine Respiratory Syncytial Virus (BRSV) and Dictyocaulus viviparus (lungworms) were both detected in a fresh lung sample from an adult Holstein cow who had been euthanized while in severe respiratory distress. BRSV was detected by PCR on the lung tissue. The lungworms were seen grossly upon examination of the tissue on arrival in our Receiving section and were confirmed to be Dictyocaulus viviparus within our Parasitology section. Multiple animals in this herd have been affected and two have died.
