[Development of poliovirus infection in laboratory animals of different species].
The capacity of vaccine and virulent strains of poliomyelitis virus to multiply in laboratory animals of different species was studied. Virus reproduction was judged by formation of photoresistant virus progeny in response to inoculation of the animals with photosensitized virus. Multiplication of virulent poliomyelitis virus strains observed in the majority of animal species examined (monkeys, newborn and adult cotton rats, newborn and adult white mice, chickens, chick embryos) resulted in active formation of photoresistant virus population and in some cases was accompanied by clinical symptoms of the disease. Multiplication of vaccine strains was observed in a smaller number of animal species and was limited, as a rule. Among non-primate animals, newborn cotton rats were most susceptible to poliovirus infection. Newborn guinea pigs were the only species of laboratory animals in which no multiplication of any of the six strains under study could be detected.
