Abstract
Growth patterns of Nosema cuniculi ( Encephalitozoon cuniculi) in cell cultures of bovine kidney, canine kidney, feline lung, and rabbit kidney were studied. All cell cultures used were easy to manage and the last 3 are commercially-available established cell lines. The dog kidney cells were the most suitable for large-scale production of Nosema. When grown in plastic flasks with a bottom area of 75 cm2, the weekly yield from Nosema-infected canine kidney cells during the 10th to 17th week after inoculation was between 4·1 x 107 and 9·9 x 107 spores per flask. An equilibrium was obtained between the Nosema infection and the kidney cells during this time. A simple method for estimating the numbel of harvested spores is also described.Keywords
