To evaluate whether C. perfringens can be used as a model organism for studying the sporulation process in other clostridia, C. perfringens spo0A mutant IH101 was complemented with wild-type spo0A from four different Clostridium species. Wild-type spo0A from C. acetobutylicum or C. tetani, but not from C. botulinum or C. difficile, restored sporulation and enterotoxin production in IH101. The ability of spo0A from C. botulinum or C. difficile to complement the lack of spore formation in IH101 might be due, at least in part, to the low levels of spo0A transcription and Spo0A production.
