Young cynomolgus monkeys inoculated intracerebrally with an attenuated Type 1 polio virus and, after 5 days, with a monkey adapted Coxsackie A-14 virus frequently became paralyzed. Neither virus alone was capable of inducing paralysis. Similar results were observed when the AB IV strain of Coxsackie A-7 was substituted for the A-14 virus. In this case the 2nd inoculation was made intramuscularly. Paralytic poliomyelitis may at times represent the summation of two infections, the total of motor neuron destruction by two independent and noninterfering enteroviruses.

Coxsackie virus, Group A, Type 14, has been adapted to adult mice and monkeys and induces in them poliomyelitis-like lesions and, in the case of the mice, flaccid paralysis.

Gravid mice become progressively more susceptible to infection with the pancreatic line of Group B-1 Coxsackie virus during the last week of pregnancy. A Group A-8 strain did not have such an effect. The young that survive despite the fact that their mothers are infected with a B-1 strain appear to be normal in the gross and microscopically, to grow at the usual rate, to be free of demonstrable virus, and to be susceptible on challenge with a homologous strain.
