Transmission of mouse thymic virus

Area of Science:

• Virology
• Immunology
• Mouse Models

Background:

• Mouse thymic virus (MTV) is a common herpesvirus in mice.
• MTV establishes persistent infections, particularly in salivary glands.
• Previous studies have not investigated MTV transmission routes.

Purpose of the Study:

• To investigate the transmissibility of Mouse thymic virus (MTV).
• To determine transmission routes including horizontal, transplacental, and vertical (nursing).

Main Methods:

• MTV transmission was assessed through direct cage-mate contact.
• Transplacental transmission was studied in pregnant mice infected at various stages.
• Vertical transmission was evaluated via nursing from infected mothers.

Main Results:

• MTV transmission was confirmed between adult mice after prolonged contact.
• Newborns acquired MTV from mothers inoculated one day post-delivery.
• No evidence of transplacental MTV transmission was found in foetuses.

Conclusions:

• Mouse thymic virus (MTV) is transmissible horizontally between mice.
• MTV can be transmitted vertically through nursing, but not transplacentally.
• Understanding MTV transmission is crucial for mouse model research.
