To get around that problem, some researchers have tried nuclear transfer using a human cell and egg cells from rabbits or cows to produce so - called cytoplasmic hybrids, or cybrids.

For instance, by ensuring that infected males can't reproduce with uninfected females — a phenomenon called cytoplasmic incompatibility — the bacteria can maximize the number of infected offspring in the next generation and sweep through populations in very little time.
