MARCoNS in CIRS: Symptoms, testing, treatment options & why it keeps coming back

39 minutes

In this The CIRS Group Podcast episode, Jacie and Barbara explain MARCoNS (multiple antibiotic resistant coagulase-negative staphylococci) as a common deep nasal colonization in CIRS patients and why it’s addressed as step three in the Shoemaker Protocol (after leaving exposure and using binders). They discuss how MARCoNS may perpetuate inflammation and low MSH, what symptoms can look like, and how to test via a deep nasal swab (ordered from MicrobiologyDX). They review Shoemaker-style treatments such as EDTA with silver, BEG spray, plus alternatives like xylitol sprays, ozone, red light therapy, and propolis sprays, along with titration and irritation considerations. They also cover why MARCoNS can recur (ongoing exposure, incomplete eradication, pets, personal items), debate whether MARCoNS is cause vs result, and mention broader nasal testing (MicroGenDX Sinus Key) and evolving approaches beyond the patented Shoemaker Protocol.
