The genetic toolbox for the obligate intracellular bacterial species Chlamydia trachomatis and C. muridarum has rapidly expanded in recent years (Sixt and Valdivia, 2016; O’Neill et al., 2020; Fields et al., 2022), and has now extended to C. caviae, C. felis, C. pecorum, C. pneumoniae, C. psittaci and C. suis (Shima et al., 2018, 2020; Filcek et al., 2019; Marti et al., 2023; Faessler et al., In Preparation). This document comprises details for the design, construction, and transformation of various vectors into different Chlamydia species and was adapted from the original publication on calcium chloride-mediated transformation (Wang et al., 2011).
