Bovine alphaherpesvirus type 2 (BoHV-2) belongs to family Herpesviridae, subfamily Alphaherpesviridae and can cause two distinct, well-defined conditions: a generalized benign skin infection that somewhat mimics lumpy skin disease (LSD), referred to as Pseudo-Lumpy Skin Disease (PSLD) and a localized ulcerative mammillitis, referred to as Bovine Herpetic Mammillitis (BHM). BHM is a localized form of BoHV-2 infection that causes erosive-ulcerative self-limiting lesions on breast and nipples. BHM is chiefly a disease of lactating dairy cows and has been described sporadically in several countries. In this study we describe an outbreak of bovine herpetic mammillitis caused by BoHV-2 occurred in a dairy farm in Southern Italy. Clinical signs were observed in 26/59 lactating cows with the age ranging between 2 and 6 years. The affected animals were afebrile, showed lesions on the skin of nipples, breast and ventral surface of the abdomen, near the mammary veins and spontaneously recovered within 2 months.

Abstract

Bovine alphaherpesvirus type 2 (BoHV-2) belongs to family Herpesviridae, subfamily Alphaherpesviridae and can cause two distinct, well-defined conditions: a generalized benign skin infection that somewhat mimics lumpy skin disease (LSD), referred to as Pseudo-Lumpy Skin Disease (PSLD) and a localized ulcerative mammillitis, referred to as Bovine Herpetic Mammillitis (BHM). BHM is a localized form of BoHV-2 infection that causes erosive-ulcerative self-limiting lesions on breast and nipples. BHM is chiefly a disease of lactating dairy cows and has been described sporadically in several countries. In this study we describe an outbreak of bovine herpetic mammillitis caused by BoHV-2 occurred in a dairy farm in Southern Italy. Clinical signs were observed in 26/59 lactating cows with the age ranging between 2 and 6 years. The affected animals were afebrile, showed lesions on the skin of nipples, breast and ventral surface of the abdomen, near the mammary veins and spontaneously recovered within 2 months.
