| emergence of a novel shigella flexneri serotype 4s strain that evolved from a serotype x variant in china. | this paper describes the first isolation of a new shigella flexneri serotype, designated 4s, in beijing, china. genotypic and phenotypic profiling suggests that this isolate is a clone of the s. flexneri serotype x variant reference strain. of particular concern is the multidrug resistance exhibited by this isolate. | 2010 | 21177890 |
| impact of reclaimed water irrigation on antibiotic resistance in public parks, beijing, china. | the abundance and distribution of antibiotics and antibiotic resistance genes (args) in soils from six parks using reclaimed water in beijing, china, were characterized. three classes of commonly used antibiotics (tetracycles, quinolones, and sulfonamides) were analyzed by liquid chromatography-tandem mass spectrometry (lc-ms/ms). the highest concentrations of tetracyclines and quinolones were 145.2 μg kg(-1) and 79.2 μg kg(-1), respectively. detected tetg, tetw, suli, and sulii genes were quant ... | 2014 | 24071635 |
