“…In this survey, Ronsse and colleagues demonstrate supportive evidence for the influence on antibody titers due to several factors including aging, estrous stage, number of pregnancies, experience with mating, cases of abortion, management and environmental hygiene. Similar to a Swedish study published in 2012 [ 46 ], our survey had no change in antibody titer in correlation with mating, pregnancy and parturition.…”

Canine herpesvirus-1 (CaHV-1) is a globally distributed pathogen causing reproductive, respiratory, ocular and neurological disorders in adult dogs and neonatal death in puppies. This pathogen is considered poorly immunogenic, and neutralizing antibodies are found for only a short time following exposure. Further, seroprevalence can be affected by several epidemiological factors. A virological survey was conducted in a high-density population breeding kennel in Central Italy. There were several factors predisposing animals to CaHV-1 infection, such as age, number of pregnancies, experience with mating and dog shows, cases of abortion, management and environmental hygiene. Serum neutralization (SN) and nested PCR assays were used to estimate prevalence of CaHV-1. None of the submitted samples tested positive for nested PCR, and none of the sera tested CaHV-1 positive. No association was observed between antibody titers and risk factors, and no sign of viral reactivation was detected in either males or females. These results suggest that CaHV-1 is not circulating within this kennel and that further studies are needed in order to better understand the distribution of the virus within Italy.

“…It is a recognized cause of foetal and neonatal deaths, but has also been associated with reproductive disorders, such as embryo resorption, infertility, and low conception rates [4,5]. Latent CHV-1 infection does not show any negative effect on pregnancy, and pregnancy itself does not cause viral reactivation or excretion [11]. Although high antibody titres at the beginning of pregnancy are likely to protect against infertility or embryonic resorption [8], these pathological conditions have also been observed in bitches with high antibody titres [4].…”

Canine herpesvirus-1 (CHV-1) can cause abortion and foetal and neonatal deaths in the bitch. The reactivation of latent infections with asymptomatic virus shedding represents a mechanism, whereby the virus can persist in a dog population. The aim of this study was to investigate the seroprevalence of CHV-1 in a population of breeding dogs in Piedmont, Northern Italy, and to investigate the distribution of herpesvirus vaccination. The study was carried out in 370 animals that were housed in 33 breeding kennels. Antibodies against CHV-1 in serum samples were measured by means of serum neutralization. Vaccination had been performed in 21.2% of the kennels and 8.4% of the dogs. The overall seroprevalence of CHV-1 was 50.3%. In ten kennels (30.3%), no seropositive dogs were identified. The percentage of seropositive dogs ranged from 7.1% to 100% in positive kennels. More than 40% of the seropositive dogs showed high titres. Sex had no significant effect on either seroprevalence or the category of the serum titre. The number of positive animals was significantly lower in the groups of prepuberal bitches and animals younger than 1.5 years. The majority of younger animals showed very high titres, suggesting recent contact with the virus. Our data show that CHV-1 is a common infection in breeding dogs in Piedmont. Vaccination is rarely performed but might be an option, because, although many animals of breeding age already show high antibody titres, seronegative pregnant bitches will be at high risk of contracting the infection due to viral circulation in kennels where the virus is enzootic.
