Respiratory disease was identified in 86 cattle postmortem submissions between October and December 2018. The most common pathogens identified included Mycoplasma bovis (21 cases), Dictyocaulus viviparus (14 cases), Mannheimia haemolytica (14 cases), Pasteurella multocida (12 cases), respiratory syncytial virus (10 cases) and Trueperella pyogenes (nine cases).
Pulmonary thromboembolism was diagnosed on postmortem examination of a 10-year-old dairy cow that had died following respiratory signs. Phlebitis of the left milk vein was detected with localised cellulitis, skin ulceration and spread to the lungs of thrombi containing bacterial organisms. T pyogenes was recovered from the lesions.
Parasitic pneumonia (husk)
Parasitic pneumonia due to D viviparus was diagnosed in a group of calves being reared in calf paddocks that had been grazed by similar animals the previous season. Parasitic gastroenteritis (PGE) was also diagnosed in the group and it was considered that the paddocks had likely been contaminated by the previous year’s calves.
A total of 14 outbreaks of parasitic pneumonia were investigated through the submission of carcases for postmortem examination during the reporting period. This was in addition to the testing of 151 faecal samples from cattle in different herds for the presence of lungworm larvae.
