pubmed-article:3512417 | pubmed:abstractText | Transferrin and, to a lesser extent, insulin were two components of serum that enhanced the survival of Treponema pallidum in microaerophilic, acellular medium. These two components also enhanced the attachment of T pallidum to baby rabbit genital organ (BRGO) cells in both aerobic and microaerophilic tissue culture systems. Growth hormone and epidermal growth factor marginally enhanced the attachment of T pallidum to BRGO cells. | lld:pubmed |
