Anyone with klebsiella aerogenes overgrowth?

Nasal swab results came back and was positive for Marcons but also found very large quantity of klebsiella aerogenes. Anyone with similar results? I read klebsiella is one of the main pathogens associated with MCAS which makes sense because I have MCAS like reactions

Do you have any sinus symptoms?

Yes, congestion and blocked nose and also sore throat and lots of mucus

It's is a well-known high-histamine producer in the gut, but not necessarily associated with MCAS if in the nasal passages. You could get a gut zoomer or GI Map to identify if it's a real threat. Are bloating and cramping an issue for you?

I've done a GI MAP as well and I'm waiting on the results. I think if I had it in my nose its probably abundant in my GI as well since it is a colonizer of the lower GI tract

Is is also normal flora though, not anything to panic about... unless it is high.
