The spirochete and multiple sclerosis
Abstract:
Cultures on anaerobic medium were made of the spinal fluids of 27 patients with multiple sclerosis and 13 controls after the method described recently by Ichelson. Where Ichelson found organisms resembling spirochetes in 78 per cent of patients with multiple sclerosis, we found some form of what appeared to be a living micro-organism in 18.5 per cent. The control fluids were all sterile. The work requires confirmation and amplification.
Insights
Researchers investigated microorganisms in spinal fluid from multiple sclerosis patients. While previous studies found organisms in 78% of cases, this study identified potential microorganisms in 18.5% of multiple sclerosis patients, with sterile controls.
Area of Science:
- Microbiology
- Neurology
Background:
- Multiple Sclerosis (MS) is a chronic neurological disease.
- The etiology of MS remains incompletely understood.
- Previous research suggested a potential microbial link in MS.
Purpose of the Study:
- To investigate the presence of microorganisms in the cerebrospinal fluid (CSF) of patients with multiple sclerosis (MS).
- To compare findings with a previous study by Ichelson.
- To assess for microbial presence in control subjects.
Main Methods:
- Cerebrospinal fluid samples were collected from 27 patients diagnosed with MS and 13 healthy controls.
- Cultures were performed on an anaerobic medium using Ichelson's described method.
- Microscopic examination of cultures was conducted.
Main Results:
- Microorganisms resembling those described by Ichelson were identified in 18.5% of MS patients' CSF.
- No microorganisms were detected in the CSF of any control subjects (0%).
- The prevalence of detected microorganisms was lower than reported in the Ichelson study.
Conclusions:
- The presence of a potentially living microorganism in the CSF of some MS patients warrants further investigation.
- The findings suggest a possible, though less prevalent than previously reported, microbial association with MS.
- Further research is required to confirm and expand upon these preliminary results.
