"The team found that C. ljungdahlii invades C. acetobutylicum. The two organisms combine cell walls and membranes and exchange proteins and RNA to form hybrid cells, some of which continue to divide and in fact differentiate into the characteristic sporulation program"
I read that as saying the new chimera (...?) is viable.
Given "and RNA to form hybrid cells" it would be hard to see them unhybridising; would that even be possible once you've mixed up so much? So I read the former where you read the latter, but it needs clarifying doesn't it.
