Immunology of infective preterm delivery in the mare

Abstract: Placentitis is reported to be the cause of 9.8-33.5% of abortions, stillbirths and perinatal losses in horses. Bacterial infections are responsible for 53% of placentitis cases with Streptococcus equi ssp. zooepidemicus being isolated in 28% of these cases. Clinically, mares may have a vaginal discharge, show udder development, lactate prenatally and deliver a premature or dead foal. Major aspects of the pathogenesis of infectious preterm delivery that may require more effective therapeutic targeting are myome… Show more

“…With respect to the possible relevance of equine to human birth, it is noteworthy that parturition can be induced in mares with oxytocin [181], where in most other species, it can only hasten delivery of fetuses once parturition has already begun [182]. More importantly, mares experience a significant incidence of preterm delivery and fetal loss due to placentitis [183] with a similar cytokine response [184]. This is a spontaneous and naturally occurring syndrome and surely has greater potential value for that reason over experimentally manipulated "models" [185].…”

“…En yeguas con placentitis, el cuadro hemático puede evidenciar leucocitosis con neutrofília. Este resultado paraclínico es variable porque la infección no suele ser de importancia sistémica, así mismo en casos avanzados puede existir una hiperfibrinogenemia, Lyle (2014). En la mucosa múltiples nodulaciones entre 0.1-0.3 cm de coloración entre roja y amarilla.…”

“…Las infecciones ascendentes intrauterinas están asociadas con bacterias que migran desde la vagina infectando los tejidos cercanos al cérvix, estableciendo un foco inflamatorio primario. El huésped responde con procesos inflamatorios agudos, caracterizado en las primeras 48 horas con la producción de prostaglandinas (prostaglandina E2 y prostaglandina F2α); así mismo, citoquinas pro-inflamatorias (IL-6 e IL-8, principalmente) que favorecen la mayor producción de prostaglandinas por parte del amnios y corion Lyle, 2014), éstas pueden generar una hipermovilidad posterior que puede impedir el flujo de sangre de la placenta a medida de que se contrae, reduciendo la oxigenación que debe recibir el feto y favoreciendo su estrés, Reed et al, (2005). El objetivo del presente reporte es describir un caso de aborto asociado a placentitis aguda de origen infeccioso por posibles enterobacterias (E.coli, Salmonella sp) en una yegua de raza silla francesa de 10 años de la ciudad de Bogotá (Colombia).…”

“…Of all abortions, premature deliveries and perinatal deaths in horses, about 10 to 30% can be attributed to placentitis. As such, placentitis is a common cause of perinatal mortality (Giles et al, 1993;Hong et al, 1993b;Smith et al, 2003;Troedsson, 2003;Laugier et al, 2011;Lyle, 2014).…”
