    Los mamíferos domésticos y silvestres cumplen un rol importante en la epidemiología de la leptospirosis. El visón americano Neogale vison es un mustélido introducido en Argentina que podría actuar como portador/reservorio de leptospiras en la región. Nuestro objetivo fue estudiar la presencia de Leptospira spp. en muestras de orina y riñón de visones capturados (n = 25) en el sur de la provincia de Neuquén. No detectamos la bacteria en ninguna de las muestras analizadas. Sin embargo, consideramos importante profundizar estos estudios dados los hábitos semiacuáticos del visón americano, su interacción con especies silvestres, domésticas y con humanos, y su continua expansión.Both wild and domestic mammal species play an important role in the epidemiology of leptospirosis. The American mink Neogale vison has been introduced in Argentina, where it could act as a carrier or reservoir of leptospiras. Our objective was to study the presence of Leptospira spp. in urine and kidney samples of individuals (n= 25) captured in Southern Neuquén province. No Leptospira spp. were detected in the analyzed samples. However, we highlight the importance of broadening these studies given the semiaquatic habits of the American mink, its interaction with wild and domestic species and also with people, and its continuous expansion.Instituto de BiotecnologíaFil: Gozzi, Ana Cecilia.

    NEOTROPICAL ALIEN MAMMALS: a data set of occurrence and abundance of alien mammals in the Neotropics

    Biological invasion is one of the main threats to native biodiversity. For a species to become invasive, it must be voluntarily or involuntarily introduced by humans into a nonnative habitat. Mammals were among first taxa to be introduced worldwide for game, meat, and labor, yet the number of species introduced in the Neotropics remains unknown. In this data set, we make available occurrence and abundance data on mammal species that (1) transposed a geographical barrier and (2) were voluntarily or involuntarily introduced by humans into the Neotropics. Our data set is composed of 73,738 historical and current georeferenced records on alien mammal species of which around 96% correspond to occurrence data on 77 species belonging to eight orders and 26 families. Data cover 26 continental countries in the Neotropics, ranging from Mexico and its frontier regions (southern Florida and coastal-central Florida in the southeast United States) to Argentina, Paraguay, Chile, and Uruguay, and the 13 countries of Caribbean islands. Our data set also includes neotropical species (e.g., Callithrix sp., Myocastor coypus, Nasua nasua) considered alien in particular areas of Neotropics. The most numerous species in terms of records are from Bos sp. (n = 37,782), Sus scrofa (n = 6,730), and Canis familiaris (n = 10,084); 17 species were represented by only one record (e.g., Syncerus caffer, Cervus timorensis, Cervus unicolor, Canis latrans). Primates have the highest number of species in the data set (n = 20 species), partly because of uncertainties regarding taxonomic identification of the genera Callithrix, which includes the species Callithrix aurita, Callithrix flaviceps, Callithrix geoffroyi, Callithrix jacchus, Callithrix kuhlii, Callithrix penicillata, and their hybrids. This unique data set will be a valuable source of information on invasion risk assessments, biodiversity redistribution and conservation-related research. There are no copyright restrictions.
