MASTITIS AFTER INDUCED MAMMOGENESIS IN A NULLIPAROUS GOAT

ABSTRACT This is a case report on a nulliparous Toggenbourg goat, one year of age that, after being submitted to superovulation with human menopause gonadotrophin, presented mammogenesis and lactogenesis. Both neoformed mammary glands were naturally infected with β-hemolytic Staphylococcus aureus and evolved clinically in different forms. The left half evolved to acute catarrhal mastitis that responded positively to treatment using sodium cloxacillin, whereas right mammary gland evolved to phlegmonous gangrenous mastitis, with teat loss. The mammary tissue remaining had to be surgically removed. The present report emphasizes that multi-tissue effect should not be ignored when hormonal therapy is used. The potential risk of induced mammogenesis in nulliparous animals and the nosological diversity that mastitis may present should be considered, once the etiological agent and host were the same, and different inflammatory responses were observed in the two halves.
