Identification and evaluation of new Mycobacterium bovis antigens in the in vitro interferon gamma release assay for bovine tuberculosis diagnosis por Eirin, Maria Emilia, Macías, Analía, Magnano, Gabriel, Morsella, Claudia Graciela, Mendez, Laura Luján, Blanco, Federico Carlos, Bianco, María Veronica, Severina, Walter, Alito, Alicia Elsa, Pando, Maria de los Angeles, Singh, Mahavir G., Spallek, Ralph, Paolicchi, Fernando, Bigi, Fabiana, Cataldi, Angel Adrian

“…Its diagnosis is based on the detection of cell mediated immunity under the exposure to protein purified derivative tuberculin (PPD), a complex and poorly characterized reagent. The cross-reactivity to non-tuberculous mycobacterium species (false-positive results) has been crucial to develop a more proper antigen. …”

Plants vs. Streams: Their groundwater‐mediated competition at “El Morro”, a developing catchment in the dry plains of Argentina por Jobbagy Gampel, Esteban Gabriel, Lorenzo, Santiago, Buono, Nicolás, Páez, Ricardo, Diaz, Yésica, Marchesini, Victoria, Nosetto, Marcelo Daniel

“…Intense ecological and geomorphological transformations in this catchment exposed the interplay of five mechanisms governing evapotranspiration/streamflow partition including (i) unsaturated uptake and both (ii) riparian and (iii) distributed uptake from the saturated zone by plants, as well as (iv) deepening incisions and (v) sediment deposits over riparian zones by streams. Acknowledging the complex interplay of these mechanism with groundwater is crucial to predict and manage future hydrological changes in the dry plains of South America.…”

Persistent Southern Tomato Virus (STV) Interacts with Cucumber Mosaic and/or Pepino Mosaic Virus in Mixed- Infections Modifying Plant Symptoms, Viral Titer and Small RNA Accumulati... por Elvira-González, Laura, Peiró, Rosa, Rubio, Luis, Galipienso, Luis

“…Here, we studied the effect of STV in co- and triple-infections with Cucumber mosaic virus (CMV) and Pepino mosaic virus (PepMV). Our results showed complex interactions among these viruses. Co-infections leaded to a synergism between STV and CMV or PepMV: STV increased CMV titer and plant symptoms at early infection stages, whereas PepMV only exacerbated the plant symptoms. …”
