Resumen: Describimos un caso de encefalitis asociada a infección por astrovirus bovino neurotrópico en una vaca lechera, raza Jersey, del departamento de San José, Uruguay. Este representa el segundo caso reportado de esta condición en el hemisferio sur. La vaca, única
afectada de un rodeo de 70 bovinos, manifestó signos clínicos neurológicos con curso de 2 días, luego de los que murió espontáneamente. El examen histopatológico reveló meningoencefalitis linfocítica, histiocítica y plasmacítica, con necrosis neuronal, sin cuerpos de inclusión. No se
detectaron en el cerebro otros agentes infecciosos, incluyendo el virus de la rabia (Lyssavirus), alfaherpesvirus bovino-1 y alfaherpesvirus bovino-5 (Varicellovirus), virus de la diarrea viral bovina (Pestivirus), virus del Nilo Occidental (Flavivirus), Listeria monocytogenes, Histophilus somni y otras bacterias. Dado que el descubrimiento de astrovirus neurotrópicos en varias especies de mamíferos, incluidos humanos, es reciente, proponemos que los casos de encefalitis por astrovirus pudieron haber pasado inadvertidos en Sudamérica. Discutimos brevemente
el diagnóstico patológico diferencial de encefalitis infecciosas en bovinos. bstract We describe a case of neurotropic bovine astrovirus-associated encephalitis in a Jersey dairy cow from the department of San José, Uruguay. This represents the second case of this
condition reported in the Southern Hemisphere. The cow was the only one affected in a herd of 70 cows, showing neurological signs with a 2-day clinical course, before dying spontaneously. Histopathological examination revealed lymphocytic, histiocytic, and plasmacytic meningoencephalitis with neuronal necrosis, without detectable inclusion bodies. Other infectious agents, including Rabies virus (Lyssavirus), Bovine alphaherpesvirus-1 and Bovine alphaherpesvirus-5 (Varicellovirus), Bovine viral diarrhea virus (Pestivirus), West Nile virus (Flavivirus), Listeria monocytogenes, Histophilus somni and other bacteria, were not detected in the brain. We propose that given the recent discovery of neurotropic astroviruses in various mammalian species, including humans, cases of astrovirus encephalitis may have gone undetected in South America.We briefly discuss the differential pathologic diagnosis of infectious bovine encephalitis.

ABSTRACT.
Background: Asian soybean rust (SBR) caused by Phakopsora pachyrhizi Syd. & Syd., is one of the main diseases affecting soybean and has been reported as one of the most economically important fungal pathogens worldwide. Knowledge of the genetic diversity of this fungus should be considered when developing resistance breeding strategies. We aimed to analyze the genetic diversity of P. pachyrhizi combining simple sampling with a powerful and reproducible molecular technique. Results: We employed Amplified Fragment Length Polymorphism (AFLP) technique for the amplification of P. pachyrhizi DNA extracted from naturally SBR-infected plants from 23 production fields. From a total of 1919
markers obtained, 77% were polymorphic. The high percentage of polymorphism and the Nei's genetic diversity coefficient (0.22) indicated high pathogen diversity. Analysis of molecular variance showed higher genetic variation within countries than among them. Temporal analysis showed a higher genetic variation within a year than between years. Cluster, phylogenetic and principal co-ordinate analysis showed that samples group by year of collection and then by country sampled. Conclusions: The study proposed combining a simple collection of urediniospore with a subsequent analysis by AFLP was useful to examine the molecular polymorphism of samples of P. pachyrhizi collected and might have a significant contribution to the knowledge of its genetic diversity. Also, AFLP analysis is an important and potent molecular tool for the study of genetic diversity and could be useful to carry out wider genetic diversity studies.
