TL;DR: In this paper, Fourier transform infrared spectroscopy (FTIR) spectra of PVA hydrogel samples showed the absorption regions of the specific chemical groups associated with poly(vinyl alcohol) (-OH, -CO, -CH2) and PVA/GA confirming the formation of crosslinked hydrogels (duplet -CH).

TL;DR: The abattoir holding pens are identified as a significant hazard and a potential control point for Salmonella contamination in the preharvest pork production chain.

TL;DR: Nineteen isolates of bovine viral diarrhea virus from Brazil were genetically characterized through partial nucleotide sequencing and analysis of the 5'UTR region, finding genetic diversity among Brazilian BVDV isolates may be responsible for vaccination and diag-nostic failure and therefore may influence the control strategies for BVDv infection in the country.

TL;DR: The results demonstrate that Leptospira spp are disseminated in the majority of the farms that raise sheep in the southeast and southwest Mesorregions of the State of Rio Grande do Sul, Brazil.

TL;DR: Molecular characterization of Bovine leukemia virus isolates from Brazil using the env gene sequences revealed a high conservation of this gene, and most of the substitutions found in the aminoacid sequences of the gp51 protein were localized in the G and H epitopes.
