Resumen: Campylobacter fetus fetus (Cff) es una importante causa de abortos en ovinos y un patógeno oportunista en humanos. La información sobre Cff como abortifaciente en ovinos en Sudamérica es limitada. Describimos un caso de aborto causado por una cepa de Cff multirresistente a antibióticos en una oveja en Uruguay. En agosto de 2017, 3/57 ovejas prenadas ?(5,3%) abortaron en una semana. El examen histopatológico de la placenta de una de ellas reveló placentitis neutrofílica fibrinonecrosante severa, vasculitis y trombosis. Cff fue aislado en microaerobiosis en agar Skirrow, y confirmado mediante amplificación del ADNr 16S por PCR seguida de secuenciación, y por PCR punto final y qPCR. Las pruebas de sensibilidad antimicrobiana revelaron resistencia a tetraciclinas, ácido nalidíxico, telitromicina y clindamicina. No se detectaron otros abortifacientes. Son necesarios más estudios para determinar la distribución geográfica, ecología, epidemiología, el impacto económico y la resistencia antimicrobiana de Cff en majadas ovinas de Uruguay.
Abstract Campylobacter fetus fetus (Cff) is a major infectious cause of abortion in sheep worldwide, and an opportunistic human pathogen. Information on Cff as an ovine abortifacientin South America is limited. We describe a case of abortion caused by a multidrug resistant
strain of Cff in a sheep in Uruguay. In August 2017, 3/57 pregnant ewes (5.3%) aborted whithin one week. Histopathologic examination of the placenta of an aborted ewe revealed severe neutrophilic and fibrinonecrotizing placentitis with vasculitis and thrombosis of the chorionic
arterioles. Cff was isolated on microaerobic culture in Skirrow agar, and further confirmed by 16S rDNA PCR amplification and sequencing, and endpoint and real time PCR assays. Antimicrobial sensitivity testing revealed resistance to tetracyclines, nalidixic acid, telithromycin and
clindamycin. Other abortifacients were not detected. Further studies are necessary to determine the geographic distribution, ecology, epidemiology, economic impact, and antimicrobial resistance of Cff in sheep flocks in Uruguay.

Abstract: Rice is an important source of methane (CH4) and other crops may be sources of nitrous oxide (N2O), both of which are powerful greenhouse gases. In Uruguay, irrigated rice rotates with perennial pastures and allows high productivity and low environmental impact. A long-term experiment with contrasting rice rotation intensification alternatives, including rice?soybean and continuous rice, was recently carried out in an Argialboll located in a temperate region of South America. To know if rotation systems influence soil microbial activity involved in CH4 and N2O emissions, the abundance and potential rate for gas production or consumption of microbial populations were measured during the rice crop season. CH4 was only emitted when rice was flooded and N2O emission was not detected. All rotational soils showed the highest rate for methanogenesis at tillering (30 days after rice emergence), while for methanotrophy, the maximum rate was reached at flowering. The abundance of related genes also followed a seasonal pattern with highest densities of mcrA genes being observed at rice flowering whereas pmoA genes were more abundant in dry soils after rice harvest, regardless of the rotation system. Differences were found mainly at tillering when soils with two consecutive summers under rice showed higher amounts of mcrA and pmoA gene copies. The potential denitrification rate was highest at the tillering stage, but the abundance of nirK and nirS genes was highest in winter. Regarding ammonium oxidation, bacterial amoA abundance was higher in winter while the archaeal amoA gene was similar throughout the year. A strong influence of the rice growth stage was registered for most of the parameters measured in rice paddy soils in this no-till rice intensification experiment. However, differences among rotations begin to be observed mainly at tillering when the abundance of populations of the methane and nitrous oxide cycles seemed to respond to the rice intensification.
