Animal cells in culture are microorganisms

Abstract

Pick up any textbook with 'Microbiology' in the title and observe the scant to nonexistent treatment of animal cells in culture. Viruses do not suffer from such an exclusion. Chapters abound regaling the molecular niceties of the complex dances their components undergo while infecting bacteria or animal cells in culture. Indeed, it is normally in the latter sense only that any recognition is given to the existence of animal cells in culture. Such views pervade even the minds of those who initiate and direct activities of societies whoseraison d'être is the growth and exploitation of animal cells in culture. The author of this editorial was appointed to a Chair in Microbiology at the University of Surrey in 1983 and has worked on the growth and use of animal cells in culture continuously since 1970; he, therefore, had to reconcile his position in the university with his chosen calling. In this he was helped by undergraduates too numerous to mention who struggled mightily with essays which asked the question; are animal cells in culture microorganisms? What follows is a digest of their efforts and the views of the author.
