title: Clinical, bacteriological, cytological and pathological features of teat disorders in ewes.
abstract: We describe the features of 13 cases of teat disorders in ewes, as follows: lengthy teats (one case), papilloma infection (two), staphylococcal dermatitis (one), nodules and abscesses (two), teat bites (three), stenosis (one), orf (two), compressed teat (one). Mannheimia haemolytica, Staphylococcus epidermidis, Staphylococcus simulans or Staphylococcus aureus were isolated from samples. Sub-epithelial leucocytic infiltration at the teat duct-teat cistern border, but not lymphoid nodules, was the salient histological finding in the teat. Leucocytic infiltration and destruction of parenchyma were evident in the mammary gland. The results provide field evidence suggesting that teat lesions predispose ewes to mastitis.
