简介：
Overview
This study investigates the dynamics of Human Cytomegalovirus (HCMV) infection in neonates using in vivo imaging techniques. By employing a luciferase-recombinant virus, researchers analyze the replication and dissemination of the virus in the central nervous system and peritoneal cavity over time.
