Próba zastosowania "Mykostatyny-20" w hodowli Trichomonas foetus Ried.

Investigations have been made in order to prevent infestation of Schneider's stratum with Mucor iacemosus mould. Sensibility of a pure three days old culture of Trichomonas foetus Ried towards mycostatine has been stated in a preliminary test. Doses of the preparation containing 10 to 2000 u/ml. had no negative influence upon the protozoa, a dose of 3000 u/ml. of the nutrient only slightly inhibited their growth after 24 hours, whereas doses of 5000 to 20000 u/ml. had a very strong hampering effect after 12 hours. Doses of 30000 u/ml. and upwards proved to be lethal and killed the protozoa after 12 hours. Above mycostatine has practically no bactericidal value. Mucor racemosus mold is rather sensitive to mycostatine. Doses of this preparation, amounting to 100 u/ml. impeded the growth of the mould in the control stuff and doses of 200 u/ml. prevented its growth. Mycostatine can presumably be applied as a factor hampering the growth of Mucor racemosus mould on Schneider's stratum in cultures of Trichomonas foetus Ried.
