Fiebre manchada en Argentina. Descripción de dos casos clínicos = Spotted fever in Argentina. Description of two clinical cases
(Elsevier España, 2019-12)Las rickettsiosis son enfermedades zoonóticas transmitidas por artrópodos vectores, que en Argentina presentan 2 escenarios epidemiológicos diferenciados. Uno, en las yungas de Salta y Jujuy, involucra vectores pertenecientes ... -
Diagnóstico de Entamoeba polecki y su potencial impacto en las condiciones sanitarias de la producción porcina
(Ediciones INTA, 2019-12)En Argentina, la producción porcina constituye una actividad en constante aumento, en particular, para la pequeña agricultura familiar. No obstante, este tipo de producción posee ciertas limitaciones (estructurales y ... -
Symbionts do not affect the mating incompatibility between the Brazilian-1 and Peruvian morphotypes of the Anastrepha fraterculus cryptic species complex
(Springer Nature, 2019-12)The South American fruit fly, Anastrepha fraterculus, is clearly undergoing a speciation process. Among others, two of their morphotypes, the Brazilian-1 and Peruvian, have accumulated differences in pre- and post-zygotic ... -
Analysing nonsynonymous mutations between two Mycobacterium bovis strains with contrasting pathogenic profiles
(Elsevier, 2019-12)Mycobacterium bovis (M. bovis) is the causative agent of bovine tuberculosis, a chronic infectious disease that can affect cattle, other domesticated species, wild animals and humans. This disease produces important economic ... -
Detección de bacterias de los géneros Ehrlichia, Anaplasma y Rickettsia en garrapatas Rhipicephalus sanguineus s.l en Pergamino, Argentina = Detection of Bacteria of the Genera Ehrlichia, Anaplasma and Rickettsia in Rhipicephalus sanguineus s.l Ticks in the City of Pergamino, Argentina
(Ministerio de Salud de la Nación, Argentina, 2019-12)INTRODUCCIÓN: Las rickettsiosis, ehrlichiosis y anaplasmosis son causadas por bacterias gramnegativas intracelulares obligadas y transmitidas por artrópodos. El objetivo de este trabajo fue determinar especies de garrapatas ... -
Spontaneous Mutations in the Nitrate Reductase Gene napC Drive the Emergence of Eco-friendly Low-N2O-Emitting Alfalfa Rhizobia in Regions with Different Climates
(Springer, 2020)We have recently shown that commercial alfalfa inoculants (e.g., Sinorhizobium meliloti B399), which are closely related to the denitrifier model strain Sinorhizobium meliloti 1021, have conserved nitrate, nitrite, and ... -
