EXPERIMENT! Yogurt bacteria under the microscope--which yogurt has the most?

What yogurt bacteria is supposed to look like
I mentioned before that my doctor swears homemade yogurt has many more active/live bacteria cultures than store bought.  She also says that most probiotics do not have near the amount of live bacteria that they claim.  Since I have been eating my own home made yogurt my stomach feels so much better, so I decided to test her theory with my son's microscope and share the results with you all! I took samples from Activia, Fage, Wallabe, a whole foods brand similar to Activia, and my homemade raw organic cow's milk yogurt.  I looked in our microscope book to see what the bacteria should look like...see the picture posted to the right.  I prepared the slides and then examined each of them under the microscope.  I searched and searched for anything that looked like little nuclear colored jimmies, but I couldn't find anything that even remotely resembled this.  Granted, our microscope is a student's microscope and its' highest setting is 40x, but I thought that really meant 400x. 
 The samples below are what I saw under the microscope.

Primal Defense Probiotics
Activia brand

So obviously I have no idea what I am doing and could really use some help.  If any scientists out there would like to offer input, or assist me in redoing this experiment, I would be ever so grateful!   
Forget the brand but it is the whole foods type Activia brand

  1. Joy I'm looking into finding some help with this. From the pictures though it seams your homemade is a little more active then Activa. You need to teach me please.
