Final answer:
Candida, BV, and trich have different effects on vaginal pH. Candidiasis maintains a normal acidic pH, while BV and trichomoniasis lead to an elevated vaginal pH.
Step-by-step explanation:
The vaginal pH is an important factor in maintaining vaginal health and preventing infections. Candida, BV (bacterial vaginosis), and trich (trichomoniasis) differ in terms of vaginal pH. In vaginal candidiasis (yeast infection), the pH remains within the normal acidic range of 3.5-4.5. BV, on the other hand, is characterized by an increase in vaginal pH above 4.5, typically ranging from 5-7. Trichomoniasis also leads to an elevated vaginal pH, often greater than 4.5. The disruption of the normal acidic environment can contribute to the overgrowth of these pathogens.
