<i>Nosema cuniculi</i> : In vitro Isolation

Abstract

A mammalian microsporidian was propagated for the first time in vitro with rabbit choroid plexus monolayer cultures. Tentative classification as Nosema cuniculi (Levaditi, 1923) was established by morphologic and tinctorial characteristics and by extrusion of sintgle polar filaments with attached sporoplasin from living spores. The method permits propagation of large numbers of organisms in putre cultutre.
