Vibrio-like Bacteria Recovered from Cultures of “Spirochaeta myelophthora. ” ∗

Abstract

Summary

Of 5 cultures named “ Spirochaeta myelophthora,” received directly or indirectly from the laboratory of Miss Rose Ichelson in Philadelphia, 4 could be grown on standard aerobic media and appeared as monotrichate polar-flagellated vibrio-like bacteria. Three that grew abundantly manifested characteristics that suggest relationship to but not identity with Vibrio fetus. Cultures of 6 spinal fluid samples, 5 from multiple sclerosis, remained sterile during 46 days.
