Outbreaks of bovine herpesvirus 2 infections in calves causing ear and facial skin lesions

Abstract: We describe 3 outbreaks of superficial dermatitis caused by bovine herpesvirus 2 (BoHV-2) in dairy breed calves. Clinically, all of the affected calves were 12-26 d of age, had alopecia and crusts on the face and ears, and were non-pruritic and afebrile. Affected animals recovered spontaneously without any treatment within 2-4 wk after onset of clinical signs based on 1 herd with follow up. Histologic examination of all skin crust or tissue samples identified neutrophilic inflammation, mild hyperkeratosis, mul… Show more

“…The natural mode of transmission of BoHV-2 is not clear but it is presumed to involve mechanical vectors, particularly the milking machine, or the dermal inoculation by biting flies, such as Stomoxys calcitrans [1,9]. Intact teat skin is refractory to virus penetration, indicating that some form of teat trauma precedes infection [1].…”

“…The aetiological agent is associated with two different clinical forms, a localized skin disease named bovine mammillitis, bovine herpes mammillitis, or bovine ulcerative mammilitis and a generalized disease called Pseudo-Lumpy Skin Disease (PLSD). BoHV-2 infection has been reported in Africa (South Africa, Kenya, Tanzania, Rwanda-Burundi), Europe, the United States, and Australia (2)(3)(4)(5). Recently, the virus was isolated from a clinical case of PLSD in northern Italy (6).…”

“…Likewise, there is no evidence of human infection, in spite of attempts to reproduce the infection upon inoculation of volunteers (Martin et al 1966). Large outbreaks of BoHV-2-associated cutaneous disease occurring in a 10-year-period were described in dairy breed calves in California, US (Watanabe et al 2017). These findings suggest that, like to other simplex viruses, BoHV-2 may circulate silently in susceptible host populations, occasionally producing clinical cases or outbreaks.…”
