Evidence of neurological abnormalities. 8. History of reactive arthritis or evidence of inflammatory arthritis on exam. 9. Fever within the 2 weeks prior to time of enrollment. 10. Evidence of IgA deficiency (serum IgA \< 7 mg/mL or below the limit of detection of assay). 11. HLA-B27 positive 12. Allergy or prior intolerance to two or more of the following antibiotics: azithromycin, ciprofloxacin, levofloxacin, erythromycin, ampicillin, or amoxicillin/clavulanate. 13. Allergy or prior intolerance to spirulina or spirulina products. 14. Fewer than 3 stools per week or more than 3 stools per day as the usual frequency. 15.

Use of proton pump inhibitors, H2 blockers, or other antacids within 48 hours preceding initiation of LMN-101 or placebo. 20. Use of antibiotics during the 7 days preceding initiation of LMN-101 or placebo. 21. Use of spirulina, or spirulina containing products, other than the study drug in the 30 days preceding initiation of LMN-101 or placebo. 22. Use of any investigational product within 30 days preceding initiation of LMN-101 or placebo or planned use during the active study period. 23. Use of any medication known to affect the immune system (e.g., systemic corticosteroids, chemotherapy, monoclonal antibody biologic response modifiers) within 12 months preceding initiation of LMN-101 or placebo or planned use during the active study period (excluding inhaled steroids with spacer). 24. History of prior exposure to Campylobacter including by vaccination or infection in previous trials, or serum immunoglobulin A (IgA) titer to C. jejuni glycine extract \>1:4000. 25. Other dietary or environmental exposures that may place the subject at high risk for prior Campylobacter exposure (to be determined on a case-by-case basis by the PI). 26. Employment as a food handler; childcare worker; or caregiver for elderly, immunocompromised individuals, or other at-risk population. 27. History of major mental illness such as schizophrenia, major depression or suicidal ideation 28. Any other criteria which, in the Principal Investigator's opinion, would compromise the ability of the subject to participate in the study, the safety of the study or the results of the study. 29.
