One reservoir for resistance genes where they can be exchanged among bacteria — and possibly end up in the food chain — is the sediment in marine fish farms even when no antibiotics have been applied.

A few years later, O'Neill and others made a startling discovery: They didn't even need to couple Wolbachia to infection resistance genes.

«Even though the specific molecular changes that are found in PCB - resistant tomcod and killifish are different, in both species AHR2 seems to be one of the genes — possibly the major gene — that is responsible for the resistance,» Hahn said.

«For all of the bacteria we tested, their conjugation rate is sufficiently fast that, even if you don't use antibiotics, the resistance can be maintained — even if the genes carry a high cost.»

It may take as long to breed a new resistance gene into a new cultivar as to introduce a new fungicide (± 10 years), even though this time can be shortened somewhat today with molecular tools by reducing the back - crossing cycles.

If the chicken coops of subsistence farmers are hot spots of resistance gene transfer, he speculated that bacteria present in industrial farming operations — where chickens regularly receive antibiotics — would see even more pressure to share resistance genes.

Bacteria can acquire resistance by getting a copy of a gene encoding an altered protein or an enzyme like beta lactamase from other bacteria, even from those of a different species.

Monitoring parasite populations for a specific genetic background — in this case, a fixed set of four well - defined mutations in the fd, arps10, mdr2, and crt genes — could allow researchers to assess the likelihood of new resistance - causing mutations emerging in different locations, helping to target high - risk regions even before resistant parasites take hold.

The next step will be to stack these two genes to determine if they can work synergistically and enhance blight resistance even higher.
