Project description:Duck enteritis virus (DEV) is an important herpesvirus pathogen of waterfowl associated with an acute, highly contagious lethal disease. Using a deep sequencing approach on RNA from infected chicken embryo fibroblast (CEF) cultures, we determined the global changes in the microRNA (miRNA) expression profiles during DEV infection. In addition to the changes in the expression of a number of host miRNAs as a result of DEV infection, we identified several novel DEV-encoded miRNAs. Unlike most Mardivirus-encoded miRNAs, the majority of the DEV miRNAs were encoded within the unique long region of the viral genome. The precursors of DEV miR-D18 and miR-D19 overlapped with each other suggesting similarities to miRNA-offset RNAs, although only the DEV-miR-D18-3p was functional in reporter assays. Identification of these novel miRNAs will add to the growing list of virus-encoded miRNAs enabling the exploration of their roles in pathogenesis. Each microRNA is spotted on the array 6 times. We compared expression of duck enteritis virus (DEV)-infected chicken embryo fibroblasts (CEF) with CEF control.

Project description:Mammalian species have co-evolved with intestinal microbial communities that can shape development and adapt to environmental changes, including antibiotic perturbation or nutrient flux. In humans, especially children, microbiota disruption is common, yet the dynamic microbiome recovery from early-life antibiotics is still uncharacterized. Using a mouse model mimicking pediatric antibiotic use, we found that therapeutic-dose pulsed antibiotic treatment (PAT) with a beta-lactam or macrolide altered both host and microbiota development. Early-life PAT accelerated total mass and bone growth, and resulted in progressive changes in gut microbiome diversity, population structure, and metagenomic content, with microbiome effects dependent on the number of courses and class of antibiotic. While control microbiota rapidly adapted to a change in diet, PAT slowed the ecological progression, with delays lasting several months in response to the macrolide. This study identifies key markers of disturbance and recovery, which may help provide therapeutic targets for microbiota restoration following antibiotic treatment. C57BL/6J mice received three antibiotic courses: at days 10-15, 28-31, and 37-40 of life, amoxicillin or tylosin.Livers were collected at age 22 weeks, RNA was extracted, and transcriptional differences were measured by microarray analysis.
