Placentitis (Mares) in Horses - Symptoms, Causes

Common signs of placentitis Clinical signs can be inconsistent and can often go unnoticed. Commonly reported signs are early udder development or 'bagging-up', and vaginal discharge from as early as five months of gestation. Normal mares undergo udder development 2-4 weeks prior to birth Mares suffering from placentitis may show a range of signs including a cloudy white to yellow or brown discharge from the vulva and milk dripping or running from the teats. Mares that show these external signs already have significant damage to the placenta and to the foal they are carrying Common signs of placentitis include premature udder development or lactation and sometimes vulvar discharge. In addition, often the thickened placenta can be seen on ultrasound along with separation of the membranes. Hormonal blood tests can be helpful in cases where it is unclear if placentitis is occurring mares aborting without premonitory signs. Although placentitis affects approximately 3% to 7% of pregnant mares, the value of the foals, both economically and emotionally, makes this an important disease to study. This manuscript will review endocrine changes associ-ated with placentitis, current diagnostics and treatment strategies. Endocrinolog

Common Signs Of Placentitis Unfortunately, there is not a consistent clinical sign apparent in all mares that have placentitis. Commonly reported signs are premature udder development or 'bagging-up', vaginal discharge from as early as five months gestation. Normal mares undergo udder development 2-4 weeks prior to birth Common signs of placentitis Unfortunately, there is not a consistent clinical sign apparent in all mares that have a placentitis. Commonly reported signs are premature udder development or 'bagging-up', and vaginal discharge from as early as five months of gestation. Normal mares undergo udder development 2-4 weeks prior to birth mares do not exhibit classical signs of infection, premature udder development and a vaginal discharge, so infections are commonly missed. Placentitis will occur in 3 to 7% of pregnant mares. Ninety percent of infections are due to bacteria entering the vagina, traveling up to the cervix and penetrating the cervical barrier

Placentitis: A Tricky Disease With Few Warning Signs

  1. Typically, the first sign is abortion or finding a fetus dead in utero by ultrasound. Late-term losses generally occur at 10 months of gestation to term, and the mare usually does not display signs of impending parturition. Most fetuses are expelled within 2 days to 2 weeks of dying and are autolytic
  2. Placentitis in mares is most often due to an ascending infection from the caudal genital tract that crosses the cervix and progresses cranially. The outcome often depends on the extent of infection at the time of parturition
  3. Viral placentitis: Equine herpes virus 1 (EHV1) (abortion strain) Abortion: EHV-1. Occasionally EHV4 involved. Respiratory signs in mare in early stages. Abortion rapid with early placental separation ('clean abortion'). Foals born alive are usually weak and non-viable. Chorion usually edematous, red and thickened. Fungal placentitis: Rare
  4. Placentitis is an important cause of abortion, stillbirth, and neonatal death in horses. The diagnosis of placentitis is based on occurrence of clinical signs (premature mammary gland development and vulvar discharge) and ultrasonography of the caudal placental pole. However, early and subtle cases can be missed
  5. Pregnant mares will be randomly enrolled and evaluated monthly for signs of placentitis onset. Physical exam, reproductive exam and blood samples will be collected at 90,150, 210, 240, 270 and 300 days of gestation
  6. Placentitis is a common cause of late-pregnancy abortion in mares and poses a significant threat to fetal and neonatal viability. Bacterial agents commonly associated with the occurrence of placentitis include Streptococcus equi subspecies zooepidemicus , Escherichia coli , Klebsiella pneumoniae , Pseudomonas aeruginosa , Leptospira spp.

The most common clinical signs of placentitis in mares are premature udder development and vulvar discharge. Ultrasonography is an excellent tool for monitoring fetal and placental changes in mares affected by placentitis. But since serial ultrasonographic evaluations are not commonly employed in late-gestation mares, a veterinarian can miss. Most cases of placentitis are caused by bacteria that have ascended from the mare's vulvar area up to and through the cervix. Toggle navigation. Home Signs, Symptoms and Diagnosis of Hyperthyroidism in Cats Equine Placentitis. One of the most common causes of late-term abortion in horses is placentitis. An inflammation of the placenta often caused by an infection invading the uterus via the cervix, placentitis is responsible for up to 40% of late-term abortions in mares. According to a report by C. Scott Bailey, DVM, an assistant professor of.

Placentitis in mares is caused by bacteria ascending through the caudal genital tract and is a common reason of equine abortion in late gestation, and foal deaths in the first 24 h of their lives. The most commonly isolated pathogens associated with placentitis is Streptococcus equi subspecies zooepidemicus. The bacteria, which enter the pregnant uterus through the cervix, cause inflammation of.. Bacterial placentitis is the main cause of infectious abortion in mares. Infection of the placenta via the ascending route from organisms found in the posterior genital area is the most common cause seen in practice. The most common bacteria are β-haemolytic streptococci and Escherichia coli, followed by other Gram-negative bacteria. In general the mare with ascending placentitis presents with..

Experimentally induced placentitis in late gestation mares with streptococcus equi zooepidemicus: prevention of pre-term birth. In: Uterine infections in Mares and Women: A comparative Study II, eds M. LeBlanc, J.F. Wade and L. Foster, Havemeyer Foundation Monograph Series #19, R and W Communications, Newmarket, UK, pp 13-14 Placentitis is an important condition for the veterinary surgeon because some cases are treatable if the infection is noticed early enough. Clinical Signs of Placentitis. Visible clinical signs may (but not always) include: Vaginal discharge; Premature udder development i.e. bagging up, waxing up or running milk The ability to diagnose placentitis in utero, before clinical signs of premature lactation or vaginal discharge are observed will improve the chances of successful treatment. Although it cannot be recommended to examine all mares routinely at intervals for placental abnormalities, mares with a history of problems or at high risk may be. cially in a mare that was difficult to get in foal or had an abnormally long gestation. The chorionic surface should be inspected closely for signs of placentitis, including discoloration, exu-dates, or abnormal thickening. If the placentitis has an ascending infection through the cervix, a thickened area extending from the cervical star will. PLACENTITIS. Obvious discolouration due to severe placentitis. Placentitis as the name suggests is an inflammation of the placenta. It is important as it is the single most important cause of mid to late term abortion in mares and it occurs in 3 -8 % mares. These are almost always infectious in nature, and in 90% of cases the bacteria enter via.

Ascending placentitis is a common cause of premature birth, abortion and delivery of compromised, ill foals. Recent experimental models have investigated diagnostic procedures and treatment strategie.. LEXINGTON, Ky., (Feb. 14, 2020) - The 2019-2020 foaling season has seen an increase in reports of Nocardioform placentitis, both in cases submitted to the University of Kentucky's Veterinary Diagnostic Laboratory and in reports from equine practitioners in the field. Nocardioform placentitis is an equine placental disease affecting pregnant mares and their foals during pregnancy

Placentitis in the Mare - Causes, Diagnosis, and Treatment. Placentitis, an inflammation of the placenta usually caused by an infectious agent, has emerged as a leading cause of reproductive loss in the equine breeding industry. This has a large economic and emotional impact when the pregnancy progresses until close to term but unfortunately. Mares aborting within 7 days had reduced progestin concentration (suggesting acute placentitis), while mares aborting after 8 days had an increase in progestins, suggesting chronic placentitis , probably because acute placentitis results in rapid pregnancy demise, whereas, the chronic placentitis allows for activation of fetal hypothalamic. in mares with ascending placentitis, transrectal ultrasonography is an excellent tool for monitoring foetal and placenta changes. l It has been suggested that measurements of the combined thickness of the uterus and placenta (CTUP) could be used to identify mares' risk of developing ascending placentitis or other placental disorders

Mares will be monitored using physical examination and ultrasonography for visual signs of placentitis beginning the day after inoculation. At the onset of clinical signs, drug treatment will begin for mares in treatment groups. Mares will be randomly assigned to one of three treatment groups The most common signs of placentitis in mares are premature udder development (± streaming of milk) and vulvar discharge. Transrectal and transabdominal ultrasound, combined with endocrinological assays, provide additional tools for early diagnosing and monitoring progression of placentitis in mares The broad-spectrum antibiotic might be a safe and viable option for treating infections, including placentitis, in late-term mares. Doxycycline has a long track record in both human and animal. The reasons concerning losses during the first months of pregnancy has special importance in equine reproduction. Most of these losses occur early in pregnancy and around 15-20% of mares that conceive will lose the embryo before day 50. Early pregnancy loss is generally characterized by the sudden disappearance of the embryonic vesicle and is due to different reasons

Placentitis: A Tricky Disease With Few Warning Sign

The postpartum mare: Managing basic problems (Proceedings) July 31, 2010. Michelle M. LeBlanc, DVM, DACT. The perinatal period in the mare is associated with many medical and surgical conditions that can be life threatening. These include retained placenta; metritis, laminitis, septicemia complex; colic, and rupture of a viscus, artery or uterus In pregnant mares, the uterus lies above the large colon and the caterpillar hairs can leave the colon and enter the pregnant uterus. The hairs migrate through the tissues and are commonly coated with environmental bacteria. Focal areas of infection (mucoid placentitis) occur when the hairs travel through the uteroplacental unit Blood samples were collected daily, and mares were assessed for signs of placentitis until the mare delivered, or for ten consecutive days after onset of treatment. Steroids were analyzed via RIA. Continuous data were analyzed by ANOVA, and categorical data analyzed by Fisher's exact test. Significance was set at p < 0.05 CHAPTER 60 Premature Lactation in Mares. Premature lactation in the pregnant mare can be defined as development of the mammary gland or milk production, or both, a minimum of 2 weeks before parturition. This condition is a dreaded clinical sign for the equine practitioner because it often is associated with impending abortion

Effective treatment of placentitis requires early diagnosis prior to the appearance of clinical Placentitis is a common cause of late-pregnancy abortion in mares and poses a significant threat the fetal and neonatal viability. anne m. eberhardt UK Researchers' Work Discussed at AAEP Kester News Hou Read Evidence for anti‐inflammatory effects of firocoxib administered to mares with experimentally induced placentitis, American Journal of Reproductive Immunology on DeepDyve, the largest online rental service for scholarly research with thousands of academic publications available at your fingertips Nocardioform placentitis (NP) continues to result in episodic outbreaks of abortion and preterm birth in mares and remains a poorly understood disease. The objective of this study was to characterize the transcriptome of the chorioallantois (CA) of mares with NP. The CA were collected from mares with confirmed NP based upon histopathology, microbiological culture and PCR for Amycolatopsis spp. Other conditions, such as colic, laminitis (founder) or endotoxemia, can be a consequence or occur independently from the pregnancy but threaten the life of the mare and foal. Placentitis is the number one cause of pregnancy loss in the mare. The high-risk mare program at the University of Florida specializes in mares with placentitis signs worse. With both types of CVSM, more than one of the cervical intervertebral joints can be affected. A complete neurologic examination is the first step in obtaining a diagnosis. Other diseases that can cause similar clinical signs and should be ruled out include equine protozoal myeloencephalitis (EPM), equine degenerativ

CONCLUSIONS: Mares with placentitis had significant increased SAA within 96 h post inoculation and concentrations remained increased until abortion in untreated mares. Successful treatment either prevented the rise of SAA concentration or decreased its concentration to baseline concentrations, followed by delivery of a live foal placentitis, the first clinical sign that the mare's pregnancy may be compromised is evident with bagging up early, which is horseman's lingo for premature lactation or increased udder size. Unlike ascending placentitis, there is usually no vulvar discharge in mares with nocardioform placentitis Common signs of placentitis and early detection Unfortunately, there is not a consistent clinical sign apparent in all mares that have a placentitis. Commonly reported signs are premature udder development or 'bagging-up', and vaginal discharge, as early as five months of gestation 12-24 hours after foaling. Additionally, be aware that the mare will not always develop overt clinical signs of placentitis. Occasionally, it is not determined an infection was present until post-foaling evaluation of the placental surface, further emphasizing the necessary prompt veterinary attention to the newborn foal

The equine placenta synthesizes and metabolizes progestagens, which are critical for pregnancy maintenance. Experimentally, mares that develop chronic placentitis often have increased plasma progestin concentrations, whereas mares with acute placentitis often demonstrate a rapid drop in plasma progestin concentrations occurrence of placentitis, veterinarians often recommend performing a Caslick's procedure (surgically closing the upper part of the vulva). Uterine torsion Uterine torsion (twisting of the uterus) results in a reduced blood supply to the foal. Mares will usually present with signs of colic: sometimes those signs ar

percentage of mares with placentitis exhibit clinical signs, have abnormal transrectal ultrasonographic findings, or experience changes in progestin concentra-tions. We have reported previously that ascending placentitis induced experimentally by infusion of an inoculum of S. equi subspecies zooepidemicus into th Premature placental separation and placentitis can both cause a vulval discharge. Abdominal swelling or oedema is relatively common. Healthy mares will develop some swelling on the lower belly as part of the normal process. Some mares will continue to show behavioural signs of oestrous or being in season during pregnancy for which no. I worked at an equine repro vet and was in charge of watching the mares there for signs of foaling, however it is somehow different when it's your mare foaling (she was my first horse too, so she's my baby). I'm not unfamiliar to the signs, but some people have mentioned things to me that can be watched for that I'd never heard before and I am. Mares will often lie down and continue to show signs of colic and uterine contractions as they attempt to expel the placenta. As a guideline, Manning likes to use the 1-2-3 rule of foaling: Your foal should stand within one hour, it should suckle within two hours, and your mare's fetal membranes should be discharged within three.

An external source of infection causing placentitis (ascending placentitis) migrates through the cervix, and into, most commonly, the cervical star area of the placenta. This is more commonly associated with mares that have poor reproductive conformation (tipped uterus and/or sunken anus) Some mares respond to the placentitis with premature mammary development and this can be a warning sign. Some infected mares develop a purulent vaginal discharge that can be usefully examined in the laboratory to identify the infecting organism

Foaling - Scone Equine Hospita

Placentitis is most commonly caused by bacteria from faecal contamination which ascends through the vagina and cervix. It is important to note that this infection does not occur between mares - that is, it is not contagious. Sometimes mares show signs of placentitis via a vaginal discharge or premature udder development The incidence of mares with clinical signs of placentitis was 9.5%. All of the mares that exhibited clinical signs of placentitis during gestation were treated. The treatment may explain the occurrence of only moderate placental infiltration (6/18, Table 3) and the lack of lesions (3/18, Table 3) in 50% of mares with clinica Signs on transrectal ultrasound examination consistent with placentitis and/or fetal death include: Abnormal thickening of the fetal membranes at or around the cervix. Separation of the fetal membranes from the uterine lining with or without pockets of fluid in between membranes and uterus Mares further along in their gestation, with an impending stillborn, typically provide the owner with some suspicion that all is not proceeding healthily. Clinical signs such as bagging up and or running milk prematurely, or visible vulval discharge may be noted (see information sheet on placentitis). A veterinarian should examine the mare and. In the current study, using the same inoculation model, mares were euthanized when they developed clinical signs of placentitis (i.e within 3-5 days of inoculation) before any experienced abortion. Although, our results revealed a significant decrease in CA tissue concentrations of 5α-DHP and 3α-DHP, we could not detect any significant.

Placentitis • Placentitis is a major cause of abortion in mares during the latter stages of pregnancy. o The most common route in which bacteria are introduced to the uteroplacental unit is via ascending infections, which result in inflammation and placental detachment at the cervical star region. o Hematogenous infections are also possible The clinical signs, laboratory findings, diagnosis, epidemiology, treatment, and prevention and control of two emerging causes of placentitis and abortion in horses are described in this article. Leptospirosis has been reported as a significant cause of fetal loss in horses in Kentucky, Northern Ireland, and England The issues in equine reproduction today may be as numerous as the potential advancements in the field tomorrow. Endometritis and cloning have grabbed the attention of some experts, while others, such as Scott Bailey, DVM, Dipl. ACT, are focused on contraception and placentitis. Dr. Bailey, an assistant professor of theriogenology at North. Common causes of prematurity include infection or inflammation of the placenta (placentitis) and illness in the mare. Signs of placentitis include early bagging up, dripping milk prior to foaling and occasionally vaginal discharge. If any of these signs are seen, contact your veterinarian as the mare will require treatment

Equine Placentitis - BRE

The goal for treatment of placentitis in mares is to arrest further placental damage by the infective agent and, if possible, to improve the function of the remaining normal placenta [33]. With few controlled studies in mares that evaluate drug penetration to the placenta or fetus, most treatment regimens for equine placentitis are empirical It leads to abortion or the birth of premature and weakened foals. Early detection and treatment of this condition is vital for ensuring the production of a viable foal.</p> <p>Mares with ascending placentitis often present in late term pregnancy with signs of premature udder development and premature lactation. There may be a vulvar discharge Can cause abortion, infection of sex organs in stallions, & infertility. Most common abnormality: suppurative bursitis, a pus-filled inflammation of connective tissue over the shoulders. Diagnosed through lab tests- isolate the bacteria in blood, semen, or milk of the infected horse. Antibiotics are the usual treatment; elimination of the.

Ascending Placentitis in the Mare: An Updat

The Kentucky Association of Equine Practitioners (KAEP) is circulating the notice. The VDL documented a dramatic increase in equine abortions in the second half of 2010, when 19 cases of nocardioform placentitis were diagnosed out of 247 cases. There were no known cases of nocardioform placentitis in 2009, when 218 abortions were documented While the use of estradiol cypionate in pregnant mares is generally avoided due to its reported teratogenic effects, it has nevertheless been used experimentally in late-term mares in conjunction with antimicrobials to determine its efficacy in preventing ascending placentitis. It has been reported that mares presenting with an estrogen level. Placentitis occurs most frequently during late gestation, and can be caused by a bacterial, fungal or viral infection [1,3]. Of these, ascending bacterial infection through the cervix is the most common cause of placentitis [1-4]. In many cases, mares with ascending bacterial placentitis abort acutely without any recognized clinical indicators The 2019-2020 foaling season has seen an increase in reports of Nocardioform placentitis, both in cases submitted to the University of Kentucky's Veterinary Diagnostic Laboratory (VDL) and in reports from equine practitioners in the field. Nocardioform placentitis is an equine placental disease affecting pregnant mares and their foals during pregnancy Androgens and progestins appear to be poor markers for placentitis. Serum estradiol 17β concentrations were reduced in mares with experimentally induced placentitis and appear to be a good marker for placentitis in mares. Different methods were used to study the protein composition of the fetal fluids

New Drug Protocol Holds Promise in Treating Placentitis in

All mares had blood sampled collected and were assessed for signs of placentitis daily until the mare delivered, or for 10 d after that. Steroids were analyzed via RIA. Continuous data were analyzed by ANOVA, and categorical data analyzed by Fisher's exact test. Significance was set at p0.05) Premature placental separation : Placentitis, uterine hemorrhage seen coming from the vulva to no signs of impending abortion are the variety of signs seen with this condition. Typically you see discreet pale areas on the placenta. Treatment of the underlying cause may help the mare continue the pregnancy

PLACENTITIS : Measuring placental thickness in mares

Nocardioform placentitis is a group of organisms that causes separation of the placenta from the mare's uterus. It stops nutrients and oxygen getting from the mare to the fetus, which can damage. Experimental models of placentitis are costly, foetal catheterization is difficult and commonly results in abortion, foetal size impedes a thorough, complete ultrasonographic evaluation, endocrinology of pregnancy of the mare differs from that of other species and the disease many times is silent with mares aborting without premonitory signs Currently, placentitis, an important cause of late pregnancy loss in mares, is diagnosed by clinical signs and ultrasonography. Acute phase proteins (APP) are mainly produced and secreted by the liver in response to acute inflammatory stimuli. We hypothesized that APP are increased in mares with placentitis The objective of this study was to determine the pharmacokinetics of CCFA in mares with placentitis and evaluate the disposition of the drug in fetal fluids, fetal membranes, colostrum, and serum of foals. A secondary objective was to obtain pilot data regarding the efficacy of CCFA for improving foal survival in mares with placentitis
