[Contamination of fish tissue cell cultures by Mycoplasma].
The inoculated and primary cell cultures of fish (carp, salmon, and sturgeon) have been studied. Acholeplasma typed as A. laidlawii in terms of its biochemical properties shown in inhibited metabolism has been isolated from 19 samples. The authors consider the source of Acholeplasma-induced contamination of the cell cultures under study.
