Lack of Endotoxin in Borrelia hispanica and Treponema pallidum 1

Abstract Borrelia hispanica from infected guinea pigs and Treponema pallidum from testicular syphilomas of rabbits were assayed for the presence of endotoxin with the Limulus lysate test. A suspension of Borrelia, containing 1.3 × 108 spirochetes/ml, was nonreactive both when it was tested as intact...

description Abstract Borrelia hispanica from infected guinea pigs and Treponema pallidum from testicular syphilomas of rabbits were assayed for the presence of endotoxin with the Limulus lysate test. A suspension of Borrelia, containing 1.3 × 108 spirochetes/ml, was nonreactive both when it was tested as intact organisms, and when tested after disruption of the spirochetes by sonication. Eight different suspensions of treponemes, ranging from 0.6 × 109 to 3 × 109 treponemes/ml, were negative at a 1:10 dilution and were no more active than control suspensions of normal rabbit testes. Therefore, it was concluded that T. pallidum, as well as the Borrelia, possessed no endotoxin.
