The results of pathomorphological and virological investigations in BALB/c mice infected with Coxsackie A13 virus are described. Chronic myocarditis, endocarditis, and valvulitis were discovered in mice infected 10–12 h after birth. The virus was found in the mice only for 15–20 days after infection.
