Boston - The drug-resistant salmonella bacteria is directly being linked to pigs, according to a study published in the New England Journal of Medicine.

Researchers in Taiwan report that salmonella resistant to fluoroquinolone antibiotics "can spread from swine to humans," adding, "the use of fluoroquinolones in food animals should be prohibited."

A team led by Dr. Cheng-Hsun Chiu of the children's hospital in Taoyuan, Taiwan, found that by fall of 2001, 60 percent of samples of one strain of salmonella were resistant to ciprofloxacin, a common fluoroquinolone class.

The salmonella samples from humans and swine tested had the same genetic mutations, confirming a link between human and animal illness.
