    Listeria monocytogenes is responsible for severe foodborne disease and major economic losses, but its potential reservoirs in natural ecosystems remain poorly understood. Here, we report the draft genome sequences of 158 L. monocytogenes strains isolated from black bears (Ursus americanus) in the southeastern United States between 2014 and 2017.

    Harnessing Whole Genome Sequence Data for Facility-Specific Signatures for Listeria monocytogenes: A Case Study With Turkey Processing Plants in the United States
    Brown, Phillip; Chen, Yi; Siletzky, Robin; Parsons, Cameron; Jaykus, Lee-Ann; Eifert, Joseph D.; Ryser, Elliot; Logue, Catherine M.; Stam, Christina; Brown, Eric; Kathariou, Sophia (2021-10-13)
    Listeria monocytogenes is a Gram-positive foodborne pathogen responsible for the severe disease listeriosis and notorious for its ability to persist in food processing plants, leading to contamination of processed, ready-to-eat foods. L. monocytogenes persistence in various food processing environments (FPEs) has been extensively investigated by various subtyping tools, with increasing use of whole genome sequencing (WGS). However, major knowledge gaps remain. There is a need for facility-specific molecular signatures not only for adequate attribution of L. monocytogenes to a specific FPE but also for improved understanding of the ecology and evolution of L. monocytogenes in the food processing ecosystem. Furthermore, multiple strains can be recovered from a single FPE sample, but their diversity can be underestimated with common molecular subtyping tools. In this study we investigated a panel of 54 L. monocytogenes strains from four turkey processing plants in the United States. A combination of WGS and phenotypic assays was employed to assess strain persistence as well as identify facility-specific molecular signatures. Comparative analysis of allelic variation across the whole genome revealed that allelic profiles have the potential to be specific to individual processing plants. Certain allelic profiles remained associated with individual plants even when closely-related strains from other sources were included in the analysis. Furthermore, for certain sequence types (STs) based on the seven-locus multilocus sequence typing scheme, presence and location of premature stop codons in inlA, inlB length, prophage sequences, and the sequence content of a genomic hotspot could serve as plant-specific signatures. Interestingly, the analysis of different isolates from the same environmental sample revealed major differences not only in serotype and ST, but even in the sequence content of strains of the same ST. This study highlights the potential for WGS data to be deployed for identification of facility-specific signatures, thus facilitating the tracking of strain movement through the food chain. Furthermore, deployment of WGS for intra-sample strain analysis allows for a more complete environmental surveillance of L. monocytogenes in food processing facilities, reducing the risk of failing to detect strains that may be clinically relevant and potentially novel.

    Original Études for the Developing Conductor
    Caldwell, Jonathan; Shapiro, Derek (Virginia Tech School of Performing Arts in association with Virginia Tech Publishing, 2023-04-28)

    Original Études for the Developing Conductor is a collection of supplemental études designed to enhance contemporary conducting pedagogy by amplifying the voices of composers from historically excluded groups. Each étude was commissioned from and composed by a living composer, the majority of whom are woman-identifying composers and/or composers of color. Each étude also addresses multiple specific pedagogical goals common to all conducting classrooms. Conducting textbooks commonly include musical examples to expose student conductors to various musical challenges and situations. However, due to the relative ease of using only music from the public domain, most examples found in commercially published books are excerpts of larger works composed by deceased cisgender white men of European descent. Often, this music bears little relation to a significant portion of the music contemporary students engage with and perform. These excerpts also tend to be quite short (i.e., less than a minute) and do not create cohesive, self-contained musical arcs. Are you reviewing or adopting this book for a course?
