There were also more miscellaneous genes like dnaX (polymerase subunit III), abortive infection family protein, toxin–antitoxin system, caspase (programmed cell death), outer membrane adhesion genes (ompV), many transcriptional regulators, pilus assembly genes, ATPase, reverse transcriptase and multidrug efflux SMR transporter (emrE). This evidence concerns the gene SMDT1 and infection.
