Source: Seman, B. G., et al. A Neonatal Imaging Model of Gram-Negative Bacterial Sepsis. J. Vis. Exp. (2020)The video demonstrates a neonatal mouse model for studying systemic infection using encapsulated bioluminescent bacteria. Neonatal pups are injected with high- or low-dose bacterial suspensions and returned to their mother for postnatal care. The encapsulated bacteria evade early immune detection, spread systemically, and are visualized over time using luminescence imaging. This model...

Use of In vivo Imaging to Monitor the Progression of Experimental Mouse Cytomegalovirus Infection in Neonates

Human Cytomegalovirus (HCMV) infection of neonates represents an important cause of mental retardation, yet the molecular events leading to virus-induced pathogenesis are still poorly understood. To investigate the dynamics of brain infection, we adapted whole-animal in vivo imaging to perform time-course analysis of neonates infected with a luciferase-recombinant virus.

Isolation of Alveolar Type II Epithelial Cells from Neonatal, Juvenile, and Adult Murine Lungs Adaptable to Infectious Experimental Settings
0 Views •
2025
This protocol presents a flow cytometry-based method to isolate viable alveolar type II epithelial cells (AECII) from neonatal, juvenile, or adult murine lungs (infected or non-infected). This approach enables downstream molecular and/or functional studies of AECII to identify their roles during lung inflammation and infection.

2014
A technique to isolate cholangiocytes from the extrahepatic bile ducts of neonatal mice is described. The ducts are meticulously dissected, and then cells are isolated by outgrowth in thick collagen gels. This method provides a useful tool for studying extrahepatic bile duct development and pathology.
FAQs
Rapid progression reflects the interaction between immature host defenses and limited protective barriers. Reduced innate immune responses may weaken early containment, while developing adaptive immunity can limit the newborn’s ability to mount a fully effective, targeted response. Together, these features can allow infection to become severe before localized disease remains confined, making prompt recognition especially important.
Timing and route of exposure shape the clinical context. Maternal transmission can occur before or during birth, whereas contact with caregivers or the clinical environment can introduce pathogens after birth. This distinction helps immunology and infection researchers examine how exposure intersects with developing barriers and immune responses, while guiding attention to both perinatal and postnatal sources.
Neonatal infection is not limited to one pathogen class or organ system. Bacterial, viral, and fungal causes may produce sepsis, pneumonia, meningitis, or localized disease. Understanding this range requires considering both the pathogen category and the clinical pattern, because these features provide different perspectives on how infection interacts with the newborn’s developing immune defenses.
The practical response centers on early recognition, diagnostic testing, and antimicrobial treatment. Recognition identifies newborns who may be deteriorating, testing helps investigate whether infection is present, and treatment addresses the suspected infectious process. In clinical and research settings, these steps connect immune and infectious mechanisms with decisions intended to limit progression and assess outcomes.
They extend prevention beyond care after symptoms appear. The overview identifies vaccination and maternal prevention strategies as approaches relevant to reducing neonatal infection risk, particularly around exposures linked to the mother and birth. Their inclusion shows that neonatal infection control includes preventive planning as well as recognition, testing, and treatment once illness is suspected.
It can clarify how immature innate and adaptive defenses shape susceptibility, disease pattern, and outcome during early life. Studying infections that range from localized disease to sepsis, pneumonia, or meningitis provides context for linking immune development with clinical severity. This research supports efforts to improve recognition, prevention, and treatment for newborns.
