you are talking about three different types of vaginitis: yeast is fungal bv is bacterial and trich is a parasite. bv or yeast does not cause trich. of course you can catch all three at the same time.
if i had yeast infection or bv could either one cause trich? . i was reading online that sexual transmitted infection trich can he caused by bv or yeast infections. i have a history of yeast and bacterial infections. i just recently got over strep throat. i had it twice back to back i may not have gotten rid of it the first time. i've been treated for bv 2years ago. and 3 years ago i was treated for yeast infection twice.
