Probiotics With A Purpose Antiboitics And Probiotics, Do They Cancel Each Other Out?

Antiboitics and Probiotics, do they cancel each other out? - probiotics with a purpose

I received:
Keflex
Bactrim
Zithromax
Genamicin
Penacillin
all at different times to get rid of an infection that they were not!
Also I was told that eating a lot of yogurt to avoid getting a yeast infection.
So I wonder:
Am i defeting for Antiboitics consumption of yogurt is loaded with probiotics.
It is the first time I could never remove the infection and preserve yogurt be used simultaneously.
Someone knows where I can dial directly to a website for the answers.
Please, thank you!
