Abstract:
Bovine viral diarrhea virus (BVDV) is a major pathogen worldwide, causing signifcant economic losses to the livestock sector. In Uruguay, BVDV seroprevalence at the farm level is >80%. In this work, 2546 serum, blood or tissue samples collected from animals suspected of being afected by BVD between 2015 and 2017 were analyzed by reverse transcription PCR and sequencing. Analysis of the BVDV genomic regions 5?UTR/Npro, Npro and E2 revealed that BVDV-1a, 1i and 2b circulate
in the country, with BVDV-1a being the most prevalent subtype. Population dynamics studies revealed that BVDV-1a has been circulating in our herds since ~1990. This subtype began to spread and evolve, accumulating point mutations at a rate of 3.48 × 10?3 substitutions/site/year, acquiring specifc genetic characteristics that gave rise to two local genetic lineages of BVDV-1a. These lineages are divergent from those circulating worldwide, as well as the vaccine strain currently used
in Uruguay. The most notable diferences between feld and vaccine strains were found in the E2 glycoprotein, suggesting that the amino acid substitutions could result in failure of cross-protection/neutralization after vaccination. This is the frst study that compares Uruguayan BVDV feld and vaccine strains with other BVDV strains from throughout the world. The results obtained in this study will be very useful for developing a suitable immunization program for BVDV in Uruguay by
identifying local feld strains as candidates for vaccine development. MenosAbstract:

ABSTRACT.- Background and aims: Since 1750, the species-rich grasslands native to the Río de la Plata basin in southern South America have sustained low-input livestock production. Typically, these grasslands have low herbage phosphorus (P) concentration, and P deficiency in livestock is not rare. Worldwide, P fertilization is used to increase the productivity and nutritive value of grasslands, but it is unknown whether the Río de la Plata grasslands are limited by P availability. -- Methods: We quantified the response of aboveground net primary productivity (ANPP) to P supply in a meta-analysis of 39 trials carried out between 1968 and 2016 comprising 285 independent comparisons (cases) between unfertilized controls and P-fertilized treatments. -- Results: The ANPP of unfertilized controls ranged from 400 to 17,500 kg dry matter (DM) ha-1 y-1. In 74% of cases, P fertilization did not increase ANPP. The average response was therefore low, at 399 kg DM ha-1 (relative effect + 15%), and largely unrelated to ANPP, vegetation, or soil characteristics. Conversely, in 59% of cases herbage P concentration did increase, particularly at high fertilization rates (average 0.43 mg P g DM-1; relative effect + 36%). -- Conclusions: Despite low herbage P concentration, the current ANPP of Río de la Plata grasslands seems little limited by P supply. Luxury consumption was common in response to P fertilization. Prevailing low herbage nitrogen-to-phosphorus ratios -below 11:1 in 65% of unfertilized controls- suggest nitrogen may be limiting ANPP. In this legume-scarce ecosystem, P fertilization is unlikely to boost productivity and may pose an environmental risk. © 2024 Springer Nature MenosABSTRACT.- Background and aims: Since 1750, the species-rich grasslands native to the Río de la Plata basin in southern South America have sustained low-input livestock production.
