“…Isto sugere que os abortos por infecções bacterianas ocorrem com maior frequên- cia quando as éguas estão na metade ϐinal da gestação. Tem sido mencionado que a alta incidência de aborto bacteriano em equinos ocorre entre o 5º e 10º mês de gestação (Swerczek & Caudle 2007) e que a placentite ascendente contribuiria para esta alta incidência (Hong et al 1993a, Immegart & Threlfall 2000. A idade gestacional aparentemente desempenha um importante papel no desenvolvimento da placentite que quando ocorre no ϐinal da gestação em geral é crônica e focal (Hong et al 1993b).…”

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.

“…Streptococcus zooepidemicus is one of the most common bacteria isolated from mares with uterine disease [62]. Whereas the uterus of a healthy mare is more likely to clear the infection, the uterus of a mare with impaired defense mechanisms or poor genital conformation might become inflamed or develop an infection leading to infertility.…”

“…Whereas the uterus of a healthy mare is more likely to clear the infection, the uterus of a mare with impaired defense mechanisms or poor genital conformation might become inflamed or develop an infection leading to infertility. As well, Streptococcus zooepidemicus can cause abortion via ascension through the cervix and infection of the fetus and placenta, or possibly through a maternal systemic infection [62,63]. Bacterial abortions usually occur at 5-10 months of gestation [62].…”

In addition to bacterial culture, diagnosis of infection is coupled with evidence of autolysis and inflammation of the fetus and placenta.…”

Infectious causes of embryonic and fetal mortality

The purpose of this review is to summarize bacterial, fungal, protozoan, and viral causes of reproductive dysgenesis in cattle, sheep, goats, pigs, horses, dogs, and cats. The clinical presentations of disease due to reproductive pathogens are emphasized, with a focus on assisting development of complete lists of causes that result in abortion and infertility in these species. Clinicians are encouraged to assess clinical presentation, create complete lists of differential diagnoses, obtain appropriate diagnostic samples, maximize diagnostic laboratory support, and avoid zoonotic infections resulting from reproductive pathogens of animals. The foundation of an accurate diagnosis of reproductive loss due to infectious pathogens facilitates the prudent use of immunization and biosecurity to minimize reproductive losses.

High mortality in foals associated with Salmonella enterica subsp. enterica Abortusequi infection in Italy

et al. 2018

Salmonella enterica subsp. enterica serovar Abortusequi is frequently reported as a cause of abortion in mares and neonatal septicemia and polyarthritis in Asian and African countries, but only sporadically in Europe and the United States. We report an outbreak of S. Abortusequi in foals in Italy, characterized by high mortality. In a herd of Murgese horses, 10 of 34 newborns died at birth and a further 7 died, after developing severe clinical signs, during the first 10 d of life. Tissue specimens from different organs of 2 dead foals, synovial fluids from 4 sick foals, and vaginal and rectal swabs from their dams were cultured. A total of 16 isolates, all as pure cultures, were obtained and identified as Salmonella. The isolates exhibited the same antimicrobial resistance pattern and the same sequence type, ST251, a type that has been associated with S. Abortusequi. Six of 16 isolates were serotyped and found to be S. Abortusequi 4,12:-:e,n,x. Equine practitioners should be aware of S. Abortusequi infection as a cause of neonatal mortality in foals.
