Multi-spectral kernel sorting to reduce aflatoxins and fumonisins in Kenyan maize por Stasiewicz, Matthew, Falade, Titilayo D.O., Mutuma, M., Mutiga, Samuel K., Harvey, Jagger J.W., Fox, Glen P., Pearson, T.C., Muthomi, J.W., Nelson, Rebecca

“…Discriminant analysis calibration using both infrared and visible spectra achieved 77% sensitivity and 83% specificity to identify kernels with aflatoxin >10 ng g−1 and fumonisin >1000 ng g−1, respectively (measured by ELISA or UHPLC). In subsequent sorting of 46 market maize samples previously tested for mycotoxins, 0–25% of sample mass was rejected from samples that previously tested toxin-positive and 0–1% was rejected for previously toxin-negative samples. …”

Relationship between natural occurrence of banana streak badnavirus and symptom expression, relative concentration of viral antigen, and yield characteristics of some micropropagat... por Dahal, G., Ortíz, R., Tenkouano, A., Hughes, J., Thottappilly, G., Vuylsteke, D.R., Lockhart, B.E.L.

“…The characteristics evaluated were the natural incidence of BSV based on symptoms and virus indexing, relative concentration of BSV antigens in leaf tissues determined by ELISA, and some growth and yield descriptors. Virus occurrence and symptom expression, as well as the relative concentration of BSV antigens, fluctuated greatly between seasons during the cropping cycle, being high during the rainy season and low or negligible during the hot dry season. …”

Heterogeneity in the antibody response to foot‐and‐mouth disease primo‐vaccinated calves por Di Giacomo, Sebastián, Brito, Barbara Patricia, Perez, A.M., Bucafusco, Danilo, Pega, Juan Franco, Rodríguez, L., Borca, Manuel Victor, Perez Filgueira, Daniel Mariano

“…Total FMDV‐specific antibody responses were studied against three viral strains included in the vaccine, and antibody titres were determined by liquid‐phase blocking ELISA. Three linear hierarchical mixed regression models, one for each strain, were formulated to assess the heterogeneity in the immune responses to vaccination. …”
