BACTH analysis of the homotypic interactions of C. trachomatis Incs. DHT1 bacteria were co-transformed with plasmids expressing the T25 and T18 fusions to the indicated inc proteins. The β-galactosidase activity values correspond to the average obtained from eight independent colonies. The positive control C+ corresponds to the interaction between the T25-FtsW and T18-FtsI proteins of E. coli (Karimova et al., 1998), while the negative control C- to cells harboring the empty vectors pST25 and pUT18C.
