title: In vivo development of quinolone resistance in Salmonella enterica serotype typhimurium DT104.
abstract: Salmonella enterica serotype Typhimurium definitive phage type 104 was isolated several times from the same patient over a period of 2 years. The strain developed reduced sensitivity to fluoroquinolones, and a mutation in the gyrA gene that is associated with reduced sensitivity to quinolones was identified.
