I am a 38 y.o. female with Psoriatic Athritis. I have a patch of severe psoriasis on my ankle that has been taking a long time to heal and a staph infection in my leg higher up; cultures came back postive for Staph on the ankle. Finally, Dr. took swab of my nose last week along with the ankle. The ankle was negative finally, but the nose was positive for Entrobacteria. I am a very clean person, shower daily, clean home, etc. How did I get this condition and what do I need to do to treat it?
HelloThanks for the query posted.  I would be pleased to assist you with your query.  In regard to the co relation of the infection and the psoriasis, I would like to inform you that you should get the bacteria eliminated from your body. For the same you would need to take a course of an antibiotic application like Mupirocin cream in your nose twice a day for 7 days of every month for 5 months. The infection can result in the flare up of your Psoriasis.  The bacterial infection count normally increases in patients with Psoriasis and you might have picked up the infection from anywhere. Nothing in particular.  Thanks and take care. Please do book an appointment with your Dermatologist.
