“…Lesions include placentitis (oedema and areas of necrosis in the chorion) that does not involve the cervical star . Placental disease may occasionally result in the development of hydrallantois . Macroscopically, the fetal liver may be swollen, have yellow discoloration with small nodules and microscopic disease includes a multifocal necrosis with lymphocytic/plasmacytic infiltration of hepatic portal triads and sometimes giant cell hepatopathy .…”

Summary North American horses are commonly exposed to Leptospira organisms. Leptospira Bratislava is the most common infecting serovar but this serovar has not been confirmed to cause clinical disease in North American horses. Leptospira Pomona type kennewicki is responsible for most of the clinical diseases (leptospirosis) in North American horses. Leptospirosis is most commonly associated with diseases of the placenta and fetus, the kidneys and the eyes in horses. In‐utero infections in pregnant mares may result in abortion, neonatal illness or birth of an antibody positive healthy foal. Acute renal failure in younger horses and recurrent uveitis in adult horses are other well documented clinical syndromes of leptospirosis. Abortions, neonatal disease and acute renal failure are caused by a subacute infection, while horses with Leptospira associated recurrent uveitis develop ocular disease months or years after the initial Leptospira infection. Diagnosis of Leptospirosis is made by a combination of antigen or antibody testing methods. Mares that abort following Leptospira infection have no additional clinical signs at the time of abortion but may shed the offending Leptospira spp. in the urine for several weeks. Antibiotic treatments are sometimes used in hopes of decreasing Leptospira shedding in infected horses or prophylactically in exposed pregnant mares but documentation of efficacy is lacking. Horses with Leptospira ‐ associated acute renal failure can be successfully treated with antibiotics and supportive care. Recurrent uveitis is commonly associated with leptospirosis in North American horses and although horses may have chronic intraocular infection triggering an immune disease, systemic antimicrobial therapy has not been effective in eliminating the organism from the eye. An equine approved Leptospira Pomona type kennewicki vaccine is now available in North America.

“…Hydrops of the fetal membrane is a very rare condition in all species, including the pregnant mare (Allen, 1986;Christensen et al, 2006;Govaere et al, 2013;Button et al, 2017;de Amorim et al, 2018). It is very important to recognize this condition to institute the appropriate therapy and possible hospitalization of the affected animal.…”

A case of presumptive allantois or amniotic hydrops of the fetal membranes was diagnosed in a young Intracytoplasmic Sperm Injection (ICSI) derived embryo recipient. Hydrops is a rare condition and treatment is usually focused on saving the mare. This case report describes the successful management of hydrops of the fetal membranes diagnosed in an Anglo-Argentine mare at 316 days of gestation, which resulted in a live foal. The mare was treated with broad-spectrum antibiotic therapy (30 mg/kg twice a day sulfadiazine-trimethoprim per os), an anti-inflammatory (flunixin meglumine 1.1 mg/kg once a day Intravenously (IV)), plus progestin's (altrenogest 0.44 mg/kg once daily per os) at day 328 of pregnancy, an immature foal was delivered and was immediately treated with antibiotics (ampicillin 10-20 mg/kg three times a day IV and amikacin 25-30 mg/kg once a day IV), antiacid therapy (ranitidine 1.5-2 mg/kg IV twice a day), as well as hyperimmune plasma and fluid therapy. Oxygen therapy was introduced while the foal was asleep. A commercial IgG blood test confirmed the passage of immunoglobulins. The histological architecture of the placenta revealed that both the amnion and allantois cavities were involved. This report describes one of the few hydrops pregnancy cases reported with a positive outcome for both the mare and foal. Early suspicion was found to be crucial for the positive outcome, enabling rapid hospitalization for the monitoring, treatment, and supportive care of both the mare and foal.
