Novel B2 mitogenomes from Continental southern Patagonia's Late Holocene : New insights into the peopling of the Southern Cone = Nuevos mitogenomas B2 del holoceno tardío del sur d... by Arencibia, Valeria, Muñoz Hidalgo, Marianne Graziel, Crespo, Cristian, Russo, M. Gabriela, Vera, Pablo Alfredo, Lia, Veronica Viviana, García Guraieb, Solana, Goñi, Rafael A., Avena, Sergio, Puebla, Andrea Fabiana, Dejean, Cristina

“…Discussion: The large divergence between the haplotypes presented in this study suggests either a highly variable founder gene pool, or a later enrichment by frequent biological contact with other populations. Our results underline the persistence of genetic signals related to the first waves of peopling in South America, suggesting that the regional settlement of the southern end of the continent has been much more complex than initially thought.…”

How did antibiotic growth promoters increase growth and feed efficiency in poultry? by Fernandez Miyakawa, Mariano Enrique, Casanova, Natalia Alejandra, Kogut, Michael H.

“…Thus, metabolic pathways are vital in regulating physiological health as the energetic demands of the host guides most biological functions. Mitochondria are not only the metabolic heart of the cell because of their role in energy metabolism and oxidative phosphorylation, but also a central hub of signal transduction pathways that receive messages about the health and nutritional states of cells and tissues. …”

Equine coital exanthema : New approaches to minimise the negative impact on the equine industry by Vissani, Maria Aldana

“…The infection is endemic worldwide, and the virus is transmitted mainly through direct contact during sexual intercourse and by contaminated instruments during reproductive manoeuvres in breeding facilities. The only known biological reservoir of EHV-3 is the latently infected horse; it is well-known that, as for other herpesviral infections, periods of reactivation from latency, with production and shedding of infectious virus, are the source of infection for other comingling susceptible animals. …”

Neospora caninum NC-6 Argentina induces fetopathy in both serologically positive and negative experimentally inoculated pregnant dams by Bacigalupe, Diana, Basso, W., Caspe, Sergio Gaston, More, Gastón, Lischinsky, Lilian Haydee, Gos, María Laura, Leunda, Maria Rosa, Campero, Lucía María, Moore, Prando Dadin, Schares, Gereon, Campero, Carlos Manuel, Venturini, María Cecilia

“…The objectives of this study were to genetically characterize the N. caninum NC-6 Argentina isolate using a multilocus microsatellite analysis approach and to study its biological behavior by experimental inoculations into seronegative and seropositive pregnant cattle, evaluating the humoral and cellular immune response elicited and the occurrence of transplacental transmission and fetopathy. …”

Proposals for Nothofagus antarctica diameter growth estimation: simple vs. global models by Ivancich, Horacio Simón, Martínez Pastur, Guillermo José, Lencinas, María Vanessa, Cellini, Juan Manuel, Peri, Pablo Luis

“…The unification of the simple growth models into a unique global equation did not greatly improve the accuracy of estimations, but positively influenced the biological response of the model. Another advantage of the global equation is the simple use under a wide range of natural stand conditions. …”

Immunological findings associated with Argentinean strains of Mycobacterium avium subsp. paratuberculosis in bovine models by Colavecchia, Silvia Beatriz, Fernández, Bárbara, Jolly, Ana, Minatel, Leonardo, Hajos, Silvia Elvira, Paolicchi, Fernando, Mundo, Silvia Leonor

“…The aim of this study was to evaluate the biological behavior of different Argentinean strains of MAP in two bovine infection models: macrophage (in vitro) and calf (in vivo) through the evaluation of early immune responses at the peripheral and local levels. …”

Evolution of pre‐zygotic and post‐zygotic barriers to gene flow among three cryptic species within the Anastrepha fraterculus complex by Rull Gabayet, Juan Antonio, Abraham, Solana, Kovaleski, Adalesio, Segura, Diego Fernando, Mendoza, Mariana, Liendo, María Clara, Vera, Maria Teresa

“…Our results suggest that the Mexican morphotype is a distinct biological entity and that pre‐zygotic reproductive isolation through divergence in courtship or male‐produced pheromone and other mechanisms appear to evolve faster than post‐zygotic isolation in the fraterculus species group…”

The LOV Protein of Xanthomonas citri subsp citri Plays a Significant Role in the Counteraction of Plant Immune Responses during Citrus Canker by Kraiselburd, Ivana, Daurelio, Lucas D., Laura Tondo, Maria, Merelo, Paz, Cortadi, Adriana A., Talón, Manuel, Tadeo, Francisco R., Orellano, Elena G.

“…We performed a transcriptomic analysis in Citrus sinensis leaves inoculated with the wild type X. citri subsp. citri and with a mutant strain lacking the LOV protein by a cDNA microarray and evaluated the differentially regulated genes corresponding to specific biological processes. A down-regulation of photosynthesis-related genes (together with a corresponding decrease in photosynthesis rates) was observed upon bacterial infection, this effect being more pronounced in plants infected with the lov-mutant bacterial strain. …”
