S. pneumo inhibition of Gardnerella?

I started working in our Micro lab a little over a year ago. One of the 'old-timers' told me about a test she uses to help ID Gardnerella. A thick streak of suspect Gardnerella is inoculated onto chocolate agar, then S. pneumo is streaked down the middle. After overnight CO2 incubation, Gardnerella will be inhibited by the S. pneumo zone of alpha hemolysis.

 

Neither of us has been able to find any references for this test online (after fairly cursory googling). I haven't actually tested other organisms vs pneumococcus, or other alpha streps vs Gardnerella.

 

If anyone has info on what I've been calling the sallytest, I'd appreciate it!

 

inage below is at 48 hrs, so a little messy
