Isolation of echovirus type 11 from two cases of Burkitt's tumour and three cases of other tumours

Abstract

Echovirus type I1 was isolated from two cases of Burkitt's tumour and three non-Burkitt turnour cases. Clinical and serological findings indicate that the virus was not aetiologically related to the tumours from which it was isolated, but that it represented a concurrent infection in the patients. The importance of these negative findings in strengthening the candidacy of reovirus type 3 as a possible causative agent of Burkitt's tumour is discussed.
