Researchers found that more than 99% of persisters were killed when sugar was added to a class of antibiotics known as aminoglycosides, which includes gentamicin and kanamycin.
But environmentalists and some scientists worry that a gene in the potato that confers resistance to kanamycin and neomycin, two important antibiotics, could breed bacteria that are resistant to the antibiotic.
An independent studyby French scientist Gilles-Eric Seralini released in January 2009 has strengthened their claims, finding thatBtbrinjalproduces a protein that could induce resistance to the widely-used antibiotic kanamycin.
Again, I respond with a nice email explaining that no, there is no way that ampicillin-resistant strain is also resistant to kanamycin.
So they attach a marker gene to it -- in this case a marker gene resistant to the antibiotic kanamycin.
If the new seeds are resistant to kanamycin, scientists know the engineering process worked.
Over the years they came up with a string of alternatives, including neomycin, kanamycin, gentamicin and tobramycin.
And the FDA is about to hold hearings on whether the biotech company Calgene may market a tomato containing a gene that confers resistance to the antibiotic kanamycin.
The kanamycin antibiotic gene is readily expressed in bacteria and confers resistance to serve as a selectable marker.
"Accordingly, the new agreed-upon definition of XDR-TB is the occurrence of TB in persons whose M. tuberculosis isolates are resistant to isoniazid and rifampin plus resistant to any fluoroquinolone and at least one of three injectable second-line drugs (i.e. amikacin, kanamycin, or capreomycin)."
