“…In general, equine herpesvirus-associated abortions are more prevalent than abortions caused by EAV. Numerous reports from different countries, where the percentage of EHV1 or EHV4 isolation is much higher than the isolation of EAV, confirm this thesis (Szeredi et al 2008, Laugier et al 2011). Often, EAV was not isolated at all during the observed period , Tengelsen et al 1997, Smith et al 2003.…”

“…EAV and EHV-1/4 are the causes of equine abortion in approximately 10-50% of cases, depending on the authors and horse populations studied (Tengelsen et al 1997, Laugier et al 2011, Bażanów et al 2012. In general, equine herpesvirus-associated abortions are more prevalent than abortions caused by EAV.…”

“…It is difficult to refer to similar results, because the available papers involve either a shorter observation period , Szeredi et al 2005, Szeredi et al 2008 or the isolation of EAV occurred only sporadically, e.g. the rate of EAV isolation in France in the years 1986-2009 amounted to 0.005% (Laugier et al 2011), whereas in Poland, in an comparable period, it was 17.5%. Simliarly in 1988-87 in the United Kingdom it was 0% (Smith et al 2003) (when it was 22.1% in Poland) and in 1985-89 in the United States (Michigan) it was 0% (Tengelsen et al 1997) (when it was 26.3% in Poland).…”

The purpose of the present review was a comparison of the abortions caused by EAV and EHV-1 viruses over the 34 years. A total of 452 tissues samples from aborted fetuses (347) or foals (105) stillborn or newborn that died within 72 hours were investigated. The material for the examinations came from different farms located throughout Poland. The tissue homogenates were examined by using virus isolation test in RK-13 and Vero cell lines and the cytopathic agent was confirmed as EHV-1 by the direct fluorescent antibody test or as EAV by the indirect fluorescent antibody test. The study indicated that EAV was isolated (104 cases, 23%) almost as equally often as EHV-1 (116 cases, 25.6%). Both, equid herpesvirus-associated abortion and the abortion induced by EAV were characterized by cyclicity. The percentage of EAV and EHV-1 isolation alternately reduced and increased, but the increase of isolation of one virus was accompanied by the decrease of the other. The domination of one virus over the other occurred in cycles of a few years.

“…A frequência da ocorrência de abortos nesta espécie pode variar de 8%-19% (Acland 1993, Laugier et al 2011. No Brasil em um estudo realizado no Paraná foi observado que 9,2% das perdas em propriedades de criação de equinos Puro Sangue Inglês na região de Curitiba eram devidas a abortos (Moreira et al 1998).…”

“…Em um estudo realizado na França foi encontrado que 14,5% dos abortos estavam associados à infecção por EHV-1 (Laugier et al 2011). Neste mesmo estudo a infecção bacteriana representou 50,9% dos abortos sendo que Streptococcus β-hemolítico foi responsável por 40,1% dos casos e Streptococcus equi subesp.…”

Foi realizado um estudo retrospectivo das causas de aborto ocorridas em equinos na área de influência do Laboratório Regional de Diagnóstico (LRD), da Faculdade de Veterinária da Universidade Federal de Pelotas (UFPel), no período entre janeiro de 2000 e junho de 2011. Foram revisados os protocolos de necropsia e de 1.154 equinos ou materiais de equinos recebidos 72 (6,2%) eram casos de abortos. A infecção bacteriana foi a principal causa de aborto neste estudo com 36,1% dos casos. As causas não infecciosas corresponderam a 8,3% dos casos, os abortos virais a 4,2%, os parasitários a 1,4% e os inflamatórios a 2,8%. Em 47,2% dos casos não foi possível determinar a causa/etiologia do aborto. Lesões macroscópicas e histológicas características foram observadas em casos de aborto por Leptospira sp. e por herpesvirus equino-1 sendo que nos demais casos as lesões foram inespecíficas. Ficou demonstrado que o envio do feto inteiro junto com a placenta, sob refrigeração, aumenta consideravelmente a eficiência do diagnóstico e o elevado número de abortos de causa não determinada foi atribuído em parte ao envio de material não adequado.
