Abstract
Four different cell systems are compared with regard to usefulness for the isolation of mumps virus and several techniques, in particular hemadsorption inhibition (HDI) and immunofluorescence (IF), are evaluated for efficiency and rapidity in typing of mumps virus isolates. It appears that with suitable cells, such as a line of green monkey kidney cells (GMK, AH-1), and with typing by IF (or alternatively, by HDI) virus isolation is a fairly rapid and efficient tool for the laboratory diagnosis of mumps.
