An inflammation of the vagina most commonly caused by Candida, called <u>candidiasis</u>, is characterized by some degree of vaginal itching; however, <u>candidiasis</u> does not appear to induce vaginal inflammation and is most likely due to a reduction in Lactobacillus species.
The bacteria found on roots, mainly on legumes, are related to the nitrogen cycle because nitrogen found in the environment is not usable by many species but because the bacteria can "fix" the nitrogen, it is usable by the plant which in turn it returned into the environment.
