Improved sample selection and preparation methods for sampling plans used to facilitate rapid and reliable estimation of aflatoxin in chicken feed por Kibugu, J., Mdachi, R., Munga, L., Mburu, D., Whitaker, T., Thu P. Huynh, Grace, Delia, Lindahl, Johanna F.

“…The water slurring innovation (quaternary sampling) increased aflatoxin extraction efficiency to 95.1% through reduction of both bias (−4.95) and variability of recovery (1.2–1.4) and improved both intra-laboratory precision (HorRat = 1.2–1.5) and within-laboratory reproducibility (HorRat = 0.9–1.3). Optimal extraction conditions are documented. …”

An improved Theileria parva sporozoite seroneutralization assay for the identification of East Coast fever immune correlates por Chege, Hannah, Githigia, S., Gathumbi, J., Chege, Naomi, Ojuok, Rose, Odaba, Josiah, Mwalimu, Stephen, Oboge, Harriet, Steinaa, Lucilla, Nene, Vishvanath, Lacasta, Anna

“…Methods: Herein, we describe key improvements, among them, (1) the use of frozen parasites and target cells to avoid batch-to-batch variations and (2) the development of a new assay read-out based on the detection of infected cells through flow cytometry, instead of the use of Giemsa staining and microscopic evaluation, in order to improve the reproducibility of the results. Results: The improved seroneutralization assay is not only able to detect the individual neutralizing capacity of antibodies; it also detects the additive effect of antibody combinations. …”
