Abstract: The aim of this work was to identify causes of abortion through laboratory investigations in sheep flocks in Uruguay. One hundred cases of abortion, comprising 58 fetuses, 36 fetuses with their placentas, and 6 placentas were investigated in 2015?2021. Cases were subjected to gross and microscopic pathologic examinations, and microbiological and serological testing for the identification of causes of abortion, including protozoal, bacterial, and viral pathogens. An etiologic diagnosis was determined in 46 (46%) cases, including 33 (33%) cases caused by infectious pathogens, as determined by the detection of a pathogen along with the identification of fetoplacental lesions attributable to the detected pathogen. Twenty-seven cases (27%) were caused by Toxoplasma gondii, 5 (5%) by Campylobacter fetus subspecies fetus, and 1 (1%) by an unidentified species of Campylobacter. Fourteen cases (14%) had inflammatory and/or necrotizing fetoplacental lesions compatible with an infectious etiology. Although the cause for these lesions was not clearly identified, T. gondii was detected in 4 of these cases, opportunistic bacteria (Bacillus licheniformis, Streptococcus sp.) were isolated in 2 cases, and bovine viral diarrhea virus 1 subtype i (BVDV-1i) was detected in another. Campylobacter jejuni was identified in 1 (1%) severely autolyzed, mummified fetus. BVDV-2b was identified incidentally in one fetus with an etiologic diagnosis of toxoplasmosis. Microscopic agglutination test revealed antibodies against ?1 Leptospira serovars in 15/63 (23.8%) fetuses; however, Leptospira was not identified by a combination of qPCR, culture, fluorescent antibody testing nor immunohistochemistry. Neospora caninum, Chlamydia abortus, Chlamydia pecorum, Coxiella burnetii and border disease virus were not detected in any of the analyzed cases. Death was attributed to dystocia in 13 (13%) fetuses delivered by 8 sheep, mostly from one highly prolific flock. Congenital malformations including inferior prognathism, a focal hepatic cyst, and enterohepatic agenesis were identified in one fetus each, the latter being the only one considered incompatible with postnatal life. Toxoplasmosis, campylobacteriosis and dystocia were the main identified causes of fetal losses. Despite the relatively low overall success rate in establishing an etiologic diagnosis, a systematic laboratory workup in cases of abortion is of value to identify their causes and enables zoonotic pathogens surveillance.

ABSTRACT.
In Brazil sodium monofluoroacetate (MFA) containing plants are represented by 16 species that belong to three principle genera: Palicourea ( Rubiaceae ), Amorimia ( Malpighiaceae ), and Tanaecium ( Bignoniaceae ). These plants can cause acute cardiac failure often referred to as sudden death syndrome. The objective of this paper was to determine if N. stannea contains MFA and to report the clinical signs and pathology of cattle experimentally poisoned by this plant. MFA was detected in all N. stannea plant parts except mature leaves. Niedenzuella stannea was dosed to cattle at single doses of 15-30g kg-1 bw. Clinical signs and pathology observed were similar to those reported by other MFA-containing plants. Animals showed marked tachycardia, labored breathing, muscle tremors, loss of balance, ataxia, falling, recumbence, pedaling movements, and opisthotonous leading to death in few minutes. Gross lesions included engorgement of the large veins, severe lung edema, and petechiae , ecchymosis and suffusions in the pericardium, epicardium and pleura. Histologically, hydropic vacuolar degeneration and necrosis of epithelial cells of the kidney were observed. Cattle that received daily doses of 4g kg-1 body weight for 24 days showed no clinical signs. In summary, this is the first report that N. stannea contains monofluoroacetate and causes sudden death in cattle.

RESUMO.
No Brasil as plantas que contêm monofluoroacetato de sódio (MFA) são representadas por 16 espécies e pertencem a três principais gêneros: Palicourea ( Rubiaceae ), Amorimia ( Malpighiaceae ) e Tanaecium ( Bignoniaceae ). Estas plantas podem causar falha cardíaca aguda que frequentemente é referida como síndrome da morte súbita. O objetivo deste trabalho é determinar se N. stannea contêm MFA e relatar os sinais clínicos e patológicos em bovinos associados à intoxicação experimental por esta planta. Monofluoroacetato foi detectado em todas as partes da N. stannea , exceto em folhas maduras. Niedenzuella stannea foi fornecida a bovinos em doses únicas de 15-30g kg-1 peso vivo. Os sinais clínicos e patológicos observados foram similares aos relatados pelas intoxicações por outras plantas que contêm monofluoroacetato. Os animais apresentaram taquicardia acentuada, respiração profunda, tremores musculares, perda de equilíbrio, ataxia, queda, decúbito, movimentos de pedalagem e opistótono, seguido de morte em poucos minutos. As lesões macroscópicas observadas foram ingurgitamento de grandes vasos, edema pulmonar acentuado, petéquias, equimoses e sufusões no pericárdio, epicárdio e pleura. Histologicamente foi observado degeneração hidrópica vacuolar e necrose de células do epitélio renal. Bovinos que receberam doses diárias de 4g kg-1 peso vivo por 24 dias seguidos não apresentaram sinais clínicos. Este é o primeiro relato que N. stannea contêm MFA e causa morte súbita em bovinos.
