title: Serotype variation in vibrio cholerae el tor diarrhoea in northern Nigeria.
abstract: Serotyping of Vibrio cholerae organisms causing epidemics in Zaria and environs since 1975 to 1986 shows that Hikojima serotype was prevalent from 1976-1978, but Ogawa became prevalent from 1984 till 1986. The internal and external pressures responsible for these selections are unclear.
