An outbreak of poliomyelitis caused by poliovirus type I in captive black and white colobus monkeys (Colobus abyssinicus kikuyuensis) in Kenya

Abstract

In the latter part of 1982, three black and white colobus monkeys, Colobus abyssinicus kikuyuensis, from a small breeding group maintained at the Institute of Primate Research in Kenya, became paralysed within one month. Two of these cases were fatal and the third animal survived. The clinical and pathological findings suggested a poliomyelitis-like disease. This was confirmed by the isolation of wild strains of poliomyelitis virus type I from faeces, spleen, kidney, lung and central nervous system from affected animals.
