Startup strategy for nitrogen removal via nitrite in a BAF system
(Springer, 2018-10-26)
A biological aerated filter (BAF) pilot plant consisting of two reactors (aerobic and anoxic one) was used to determine a strategy to remove nitrogen via nitrite. RNA/DNA analysis was performed to assess ...
Freshwater ecotoxicity assessment of pesticide use in crop production: Testing the influence of modeling choices
(Elsevier, 2018-10-28)
Pesticides help to control weeds, pests, and diseases contributing, therefore, to food availability. However, pesticide fractions not reaching the intended target may have adverse effects on the environment ...
Assessing the variability in transmission of bovine tuberculosis within Spanish cattle herds
(Elsevier, 2018-01-31)
In Spain, despite years of efforts to eradicate bovine tuberculosis (bTB), the disease is still endemic, with some
areas of high prevalence. In this context, the surveillance and control plans may need ...
Mycoplasma conjunctivae in insect vectors and anatomic locations related to transmission and persistence
(Elsevier, 2018-11-12)
Mycoplasma conjunctivae is an obligate microparasite that causes Infectious Keratoconjunctivitis (IKC) in Caprinae species. IKC is a long-recognised disease, but little attention has been paid to the ...
Combined effects of spray‐drying conditions and postdrying storage time and temperature on Salmonella choleraesuis and Salmonella typhimurium survival when inoculated in liquid porcine plasma
(Wiley, 2018-06-11)
The objective of this study was to determine the effectiveness of the spray-drying process on the inactivation of Salmonella choleraesuis and Salmonella typhimurium spiked in liquid porcine plasma and ...
Global-change effects on early-stage decomposition processes in tidal wetlands – implications from a global survey using standardized litter
(Copernicus Publications, 2018-05-30)
Tidal wetlands, such as tidal marshes and mangroves, are hotspots for carbon sequestration. The preservation of organic matter (OM) is a critical process by which tidal wetlands exert influence over the ...
Detection of Paralytic Shellfish Toxins in Mussels and Oysters Using the Qualitative Neogen Lateral-Flow Immunoassay: An Interlaboratory Study
(AOAC International, 2018-03-01)
Paralytic shellfish toxins (PSTs) in bivalve molluscs represent a public health risk and are controlled via compliance with a regulatory limit of 0.8 mg saxitoxin (STX)⋅2HCl equivalents per kilogram of ...
Effect of particle size of a mash concentrate on behavior, digestibility, and macroscopic and microscopic integrity of the digestive tract in Holstein bulls fed intensively
(Oxford University Press, 2018-11-01)
Twenty-four individually housed Holstein bulls (456 ± 6.9 kg of body weight and 292 ± 1.4 d of age) were enrolled in a complete randomized experiment involving four dietary treatments to evaluate the ...
Characterization of bacterial microbiota compositions along the intestinal tract in pigs and their interactions and functions
(Springer Nature, 2018-08-28)
In addition to its value in meat production, the pig is an interesting animal model for human digestive tract studies due to its physiological similarities. The aim of this study was to describe the ...
Porcine circovirus 2 (PCV-2) genotype update and proposal of a new genotyping methodology
(Public Library of Science, 2018-12-06)
Porcine circovirus 2 (PCV-2) is one of the most widespread viral infections of swine, causing a remarkable economic impact because of direct losses and indirect costs for its control. As other ssDNA ...
