Imbalance of Microflora

SBH4 col3 dp1

Living in, and on, the human body are many "friendly" microbes which share a symbiotic relationship with us. They can live in the intestines, skin and mucous membranes. They can provide a particular function or compete with potential pathogens.

An imbalance of these "friendly" microbes can cause disease. The yeast, Candida albicans, which is always present in low numbers in the mouth, anus and vagina can grow rapidly when the normal balance is disrupted. This disease is called "Thrush" or Candida.

How can this disease result? What causes the imbalance?
What are the symptoms of this disease?
