you can attach a gene for resistance to an antibiotic along with the gene of interest when inserting them into the bacterial genome. Then the antibiotic can be used to screen for which bacteria have the gene you are trying to insert.

If you expose Bacteria to an antibiotic most will die: but the few that do not die have developed a resistance to the antibiotic and can no longer be treated with that antibiotic. Making that antibiotic useless in treating that new strain of BACTERIA when a host is infected with this Resistance Strain a new antibiotic has to be used/frond to fight the Bacteria. Or the new host is in big trouble.
