Isolation
clinical specimen - human
Vienna Austria
Isolation date: 1997
Product Format frozen
Storage Conditions liquid nitrogen vapor phase
Type Strain no
Medium ATCC® Medium 712: PYG w/ Additives
Growth Conditions
Temperature: 25.0°C
Duration: axenic
Protocol: This strain is distributed as a freeze-dried preparation. See the general procedures for opening a freeze-dried vial. Aseptically add 0.5 ml of ice cold medium containing 12% (w/v) sucrose to the freeze-dried inner shell vial. Once the culture is completely rehydrated, aseptically add 1 ml of ATCC medium 712 and distribute to a 16 X 125 mm plastic screw-capped test tube or a T-25 tissue culture flask containing 5.0 ml of the same medium. Incubate the test tube culture horizontally with the cap on tight. Trophozoites should be evident in 1-5 days.
Interval: every month
