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 - A better understanding of the key characteristics influencing consumers' perception and purchase decisions of mandarins can contribute to the selection of new cultivars that assertively meet their needs and expectations, as well as to the development of strategies to increase mandarin consumption in the different markets. In this context, the aims of the present work were: i) to explore Uruguayan consumers' perception of mandarins, and ii) to identify the key characteristics that drive mandarin purchase decisions. A consumer study with 197 con-sumers was conducted in a supermarket in the metropolitan area of Montevideo (Uruguay). A word-association task was used to identify consumers' associations with mandarins, whereas a best-worst scaling was used to estimate the relative importance of specific characteristics. Results from the word association task revealed that sensory characteristics (juiciness, sweetness, color, flavor and odor) were the most salient concepts associated with a mandarin, followed by fruit characteristics and consumption context. Mandarin flavor was identified as the most important characteristic underlying consumers' purchase decisions in the best-worst scaling, followed by juiciness and high vitamin content; while packaging, size or price resulted less relevant. Consumer segments who attached different relative importance to vitamin content, price, lack of seeds and easiness to peel were identified. Results from the present work suggest that strategies to increase mandarin consumption should focus on sensory and hedonic aspects rather than package appearance or health-related oneS.

RESUMEN - Conocer las características de las mandarinas que más influyen en la percepción y la decisión de compra de los consumidores contribuye a la selección de nuevos cultivares que cumplan sus expectativas, así como las estrategias que promuevan su consumo en diferentes mercados. En este contexto, los objetivos de este trabajo fueron: i) explorar la percepción de las mandarinas por parte de los consumidores uruguayos, y ii) identificar las características que influyen en la intención de compra de mandarinas. Para ello, se desarrolló un estudio en un supermercado del área metropolitana de Montevideo (Uruguay) que incluyó 197 consumidores. Para identificar las características que el consumidor asocia con las mandarinas se utilizó el método de asociación libre, mien-tras que el método de escala mejor-peor (best-worst scaling -BWS) se aplicó para estimar la importancia relativa de determinadas características. Los resultados del primer estudio revelaron que las características sensoriales (jugosidad, dulzor, color, sabor y olor) fueron los conceptos más destacados asociados con las mandarinas, seguidos por características de la fruta y del contexto de consumo. El sabor fue identificado como la caracte-rística más importante que determina la intención de compra de los consumidores uruguayos, seguido por el contenido de jugo y de vitaminas, mientras que el envase, el tamaño del fruto o su precio resultaron menos relevantes. Se identificaron diferentes segmentos de consumidores que difieren en la importancia relativa del contenido de vitaminas, el precio, la ausencia de semillas o la facilidad de pelado. Los resultados del presente trabajo sugieren que los esfuerzos para promover el consumo de mandarinas deberían centrarse en aspectos sensoriales y hedónicos más que en aspectos relacionados con la apariencia o la salud.

RESUMO - O melhor entendimento das principais características que influenciam a percepção dos consumidores e as de-cisões de compra de tangerina pode contribuir para a seleção de novas cultivares que atendam de forma as-sertiva às suas necessidades e expectativas, bem como para o desenvolvimento de estratégias para aumentar o consumo de tangerina nos diferentes mercados.
