Simian Immunodeficiency Virus and Storage Buffer: Field-Friendly Preservation Methods for RNA Viral Detection in Primate Feces
Wilde et al., mSphere. 2023.

Simian immunodeficiency virus (SIV) infects more than 40 nonhuman primate (NHP) species in sub-Saharan Africa, but testing in wild NHP populations can be challenging. Researchers compared methods for SIV RNA preservation and recovery from NHP fecal samples stored in four different buffers. The goal of this work was to identify a robust “field-friendly” method (i.e., without freezing or refrigeration) for this effort, and the samples were collected from a mantled guereza colobus housed at the Columbus Zoo and Aquarium. The authors reported that the DNA/RNA shield is an optimal buffer for preserving SIV RNA in fecal samples in the field. Their findings will inform future fieldwork and facilitate improved approaches for studies of SIV and other RNA viruses. Supported by ORIP (P51OD011132) and NIAID.
Orthotopic Transplantation of the Full-Length Porcine Intestine After Normothermic Machine Perfusion
Abraham et al., Transplantation Direct. 2022.

Successful intestinal transplantation currently is hindered by graft injury that occurs during procurement and storage, which contributes to postoperative sepsis and allograft rejection. Improved graft preservation could expand transplantable graft numbers and enhance post-transplant outcomes. Superior transplant outcomes recently have been demonstrated in clinical trials using machine perfusion to preserve the liver. The investigators report the development and optimization of machine perfusion preservation of small intestine and successful transplantation of intestinal allografts in a porcine model.
