Inoculation with Azospirillum brasilense as a strategy to reduce nitrogen fertilization in cultivating purple maize (Zea mays l.) in the Inter-andean valleys of Peru por Condori Ataupillco, Tatiana, Alarcón Romani, Susan, Huasasquiche Sarmiento, Lucero, García Blásquez, Cayo, Padilla Castro, César, Velásquez Mantari, José, Solórzano Acosta, Richard Andi

“…Furthermore, for parameters, namely plant height, leaf nitrogen content, and cob dimensions (length, diameter, and weight), the A. brasilense inoculation treatment with 90 kg N・ha−1 was statistically equivalent or superior to the non-inoculated control with 120 kg N・ha−1. …”

Epidemiology of Pig Tuberculosis in Argentina por Barandiaran, Soledad, Marfil, Maria Jimena, Capobianco, Guillermo, Perez Aguirreburualde, María Sol, Zumarraga, Martin Jose, Eirin, Maria Emilia, Cuerda, Maria Ximena, Winter, Marina, Martinez Vivot, Marcela, Pérez, Andrés Maximiliano, La Sala, Luciano Francisco

“…These results provide novel information about the molecular diversity of M. bovis strains in pigs in Argentina and proposes the potential relevance of a multi-host system in the epidemiology of bTB in the region. The statistical models presented here may be used in the design of a low cost, abattoir-based surveillance program for bTB in the pig industry in Argentina, with potential extension to other settings with similar epidemiological conditions.…”

Quantifying the negative impact of clinical diseases on productive and reproductive performance of dairy cows in central Argentina por Masia, F., Molina, G., Vissio, Claudina, Balzarini, Mónica, De la Sota, Rodolfo Luzbel, Piccardi, Mónica Belén

“…The parameters production at peak (Ppeak) and 305-d cumulative milk production (305DY) were estimated and lactation curves were fitted using the MilkBot model. Statistical differences were found between lactations with at least one clinical disease (305DY 9,861.3 kg; Ppeak 39.5 kg/d) and those WOD (305DY 10,013.6 kg; Ppeak 40.2 kg/d). …”

P23-Specific IgY significantly reduces diarrhea and oocyst shedding in calves experimentally infected with Cryptosporidium parvum por Mira, Anabela, Garro, Carlos Javier, De Alba, Paloma, Monti, Demián Esteban, Lang, Maria Cecilia, Vivas, Alejandro, Medina, Esteban, Franco, Juan Cruz, Gutierrez, Álvaro, Schnittger, Leonhard, Wigdorovitz, Andres, Parreño, Gladys Viviana, Bok, Marina

“…Although the onset of diarrhea was delayed (3.5 to 6.5 days post-infection; p = 0.1840), and diarrhea severity was reduced (24.25 to 17 AUC; p = 0.1236), both parameters were not statistically significant. Conclusions: P23-specific IgY antibodies effectively reduced the C. parvum-induced duration of diarrhea in experimentally infected calves. …”

Field trial with vaccine candidates against bovine tuberculosis among likely infected cattle in a natural transmission setting por Ferrara Muñiz, Ximena, Garcia, Elizabeth Andrea, Blanco, Federico Carlos, Garbaccio, Sergio Gabriel, Garro, Carlos Javier, Zumarraga, Martin Jose, Dellagostin, Odir A., Trangoni, Marcos David, Marfil, Maria Jimena, Bianco, María Veronica, Abdala, Alejandro Ariel, Revelli, Javier, Bergamasco, Maria, Soutullo, Adriana, Marini, M. Rocío, Rocha, Rosana Valeria, Sánchez, Amorina, Bigi, Fabiana, Canal, Ana María, Eirin, Maria Emilia, Cataldi, Angel Adrian

“…To note, the group vaccinated with M. bovis Δmce2-phoP exhibited the highest proportion of animals without macroscopic lesions, compared to the one vaccinated with BCG, although this was not statistically supported. Conclusions: This highlights that further evaluation of these vaccines would not guarantee better protection. …”

Phenotypic characterization of immune cells in fetal tissues of cattle immunized and challenged with Neospora caninum por Rivera Maldonado, Juan E., Delay, Josepha, Hecker, Yanina, Monterubbianesi, María Gloria, Canton, German Jose, Campero, Carlos Manuel, Odeon, Anselmo Carlos, Moore, Prando Dadin

“…As expected, the immunolabeling of MHC II + and CD3 + cells in fetal tissues was associated with fetal infection with N. caninum. There were statistically significant differences in the distribution and population of the inflammatory infiltrate in relation to the immunogenic treatment and the type of tissue, with inflammatory cells being markedly less extensive fetuses from group A (dams previously exposed to N. caninum) and in brain tissue. …”

Varroa destructor parasitism and genetic variability at honey bee (Apis mellifera) drone congregation areas and their associations with environmental variables in Argentina por Galindo Cardona, Alberto, Scannapieco, Alejandra Carla, Russo, Romina Maria, Escalante, Karen, Geria, Martín, Lepori, Nicolás, Ayup, María Marta, Muntaabski, Irina, Liendo, María Clara, Landi, Lucas, Giray, Tugrul, Monmany-Garzia, A. Carolina

“…The mean proportion of Varroa was ca. 3 in 1,000 (0.0028 ± 0.0046) at the apiaries, and ca. 2 in 100 (0.0168 ± 0.0227) at the DCAs. No statistical differences were observed between apiaries and DCAs or between ecoregions, but the proportion of infested males at the DCAs was positively correlated to the distance to the apiary and a trend was observed toward higher mite loads in DCAs. …”
