Recently, a vaginal culture came back with diagnosis of Proteus to be treated with AVC cream. I'm 74, have had yeast in the past, but have never heard of Proteus. I have been in a monogamous 55-year relationship and want to know how I might have developed this? Is it a bacterium or what, what is standard treatment, for what period of time, is there likely to be a recurrence, and how do I prevent developing it again?
