(Cambridge University Press, 2014-06)The South American fruit fly, Anastrepha fraterculus, is a complex of cryptic species composed of at least seven morphotypes. Some of them, such as the Peruvian and Brazilian 1 morphotypes (which include Argentinean ... -
Physiopathological effects of Escherichia coli O157:H7 inoculation in weaned calves fed with colostrum containing antibodies to EspB and Intimin
(Elsevier, 2014-06-24)Escherichia coli O157:H7 is responsible for severe intestinal disease and hemolytic uremic syndrome (HUS), a serious systemic complication which particularly affects children. Cattle are the primary reservoir for E. coli ... -
Detection of bovine herpesvirus 2 and bovine herpesvirus 4 DNA in trigeminal ganglia of naturally infected cattle by polymerase chain reaction
(Elsevier, 2014-06-25)Establishment of latent infection within specific tissues in the host is a common biological feature of the herpesviruses. In the case of bovine herpesvirus 2 (BoHV-2), latency is established in neuronal tissues, while ... -
Cenizas del volcán Puyehue como sustrato para plantas
(Asociación Argentina de Horticultura, 2014-06-26)En junio de 2011, la erupción del complejo volcánico Puyehue expulsó a la atmósfera grandes cantidades de cenizas que actualmente están siendo evaluadas para su uso. El objetivo de este trabajo fue corroborar la viabilidad ... -
Morphometric and Cytogenetic Studies in Mimosa diversipila (Mimosoideae, Leguminosae) and Their Taxonomic and Evolutionary Inferences
(American Society of Plant Taxonomists, 2014-07)Here we describe the morphological variability, chromosome number, and chromosome size in Mimosa diversipila. This species comprises two varieties, which are distinguished by the indumentum. However, this character is ... -
Natural occurring epialleles determine vitamin E accumulation in tomato fruits
(2014-07)Vitamin E (VTE) content is a low heritability nutritional trait for which the genetic determinants are poorly understood. Here, we focus on a previously detected major tomato VTE quantitative trait loci (QTL; mQTL9-2-6) ... -
