Performing a bacterial isolation by streaking, using sterile (aseptic) technique, consider the expected outcome on the streak plate after the following: Two organisms were in the original sample. Organism G was present at twice the abundance of Organism H (so 2/3 of the original sample). The streak plate was generated using 4 areas (quadrants)- A, B, C & D. Area A was inoculated with a loop containìng 3 mìllion organisms from the original culture, which was mixed very well and considered to be homogeneous. Areas B, C & D were streaked from the previous area with a sterilized loop, with each streak transferring 2% of the organisms from the previous area (assume the relative abundance of the two organisms was maintained). What is the expected outcome in Area on this streak plate? 2d
