From the Editor
In this issue, we introduce a new journal cover for Sexually Transmitted Diseases. The background is a network configuration of the largest component in a syphilis epidemic (SD Cunningham, et al, fig 5 in 31(10): 611–615, Oct 2004). Pictures 1–4 (top to bottom) are:
1. Chlamydia trachomatis, giemsa stained inclusion in a L929 cell (Julius Schachter, UCSF).
2. Fluorescence micrograph showing a vaginal epithelial cell coated with bacteria from a subject with bacterial vaginosis (J Marrazzo, STD, 37(12): 732–744, Dec 2010).
3. Neisseria gonorrhoeae interacting with an epithelial cell using its Type IV pili (Magdalene So/Dustin Higashi, University of Arizona).
4. Treponema pallidum, fluorescent monoclonal antibody stain in a smear from a chancre (Sheila Lukehart, University of Washington).
