Quinolone resistance in clinical isolates of Campylobacter jejuni in Sweden increased more than 20-fold at the beginning of the 1990s. Resistance to 125 microgram of ciprofloxacin per ml in clinical isolates was associated with chromosomal mutations in C. jejuni leading to a Thr-86-Ile substitution in the gyrA product and a Arg-139-Gln substitution in the parC product.
20世纪90年代初,瑞典空肠弯曲菌临床分离株对喹诺酮类药物的耐药性增加了20多倍。临床分离株对每毫升125微克环丙沙星的耐药性与空肠弯曲菌的染色体突变有关,这些突变导致gyrA产物中的苏氨酸86被异亮氨酸取代,parC产物中的精氨酸139被谷氨酰胺取代。
