Fluorescence In Situ Hybridization Protocol for Visualization of Oomycetes In Vitro and In Planta.

Fluorescence in situ hybridization enables the visualization of organisms in the environment without having to culture them. Here, we describe a FISH protocol to visualize oomycete structures (mycelia, sporangiophores, sporangia, and oospores) directly as well as from colonized plant material. The protocol utilizes organic compounds with low toxicities and does not require a permeabilization step.

In situ staining with antibodies cross-reactive in pigs, cattle, and white-tailed deer facilitates understanding of biological tissue status and immunopathology.

Identifying cellular markers within archived formalin-fixed, paraffin-embedded (FFPE) tissues is critical for understanding tissue landscapes impacting animal health, but in situ detection methods are limited in veterinary species by a restricted toolbox of species-compatible immunoreagents. We identify antibodies with conserved in situ reactivity to IBA-1 (macrophages/dendritic cells), CD3ε (T cells), Pax5 (B cells), Ki-67 (cycling cells), and cytokeratin type I/II (epithelial cells) in FFPE tissues of pigs, cattle, and white-tailed deer. Multiplexed brightfield detection (IBA-1/CD3ε/Pax5) in lymph nodes of all three species demonstrated species-specific and species-conserved features of cellular architecture.

Engineering and structures of Crimean-Congo hemorrhagic fever virus glycoprotein complexes.

Crimean-Congo hemorrhagic fever virus (CCHFV) is a tickborne virus that can cause severe disease in humans with case fatality rates of 10%-40%. Although structures of CCHFV glycoproteins GP38 and Gc have provided insights into viral entry and defined epitopes of neutralizing and protective antibodies, the structure of glycoprotein Gn and its interactions with GP38 and Gc have remained elusive. Here, we use structure-guided protein engineering to produce a stabilized GP38-Gn-Gc heterotrimeric glycoprotein complex (GP38-Gn-Gc).

Physical and compositional characteristics of drinking water storage tank sediment.

Thirty-one drinking water storage tank sediment samples were collected in 13 states, 17 distribution systems, and 29 tanks over the course of 4 years. Sediment samples were characterized for elemental composition and physical properties, which were found to be inconsistent both between samples of the same distribution system and across geographical regions. Differences between samples from the same tank also indicated spatial differences in sediment composition within storage tanks.

Mobilization of porewater Pb and Zn in response to seasonal wetting and drying within contaminated floodplains.

The mobility and bioavailability of metal contaminants such as lead (Pb) and zinc (Zn) is impacted by their interactions with other sediment constituents such as iron (Fe), sulfur (S), and organic matter, which depend on sediment redox conditions. Understanding the role that water level fluctuations have on redox conditions and subsequent impacts on metal mobility is critical for predicting impacts of increased wetting and drying cycles resulting from climate-related changes or management actions. This study measured the sediment-porewater partitioning of Pb and Zn in the Coeur d'Alene River basin downstream of the Bunker Hill Superfund Site under both flooded and seasonally dry conditions.
