Prevalence and Antimicrobial Resistance of in Pork, Chicken, and Duck from Retail Markets of China.

is one of the most important foodborne pathogens associated with animal and human diseases. In this study, 672 samples of fresh meat (pork, 347; chicken, 196; and duck, 129) were collected from retail markets in different provinces of China from 2010 to 2014. We identified 10 different serotypes among 80 isolates, whereas 12 isolates were nonmotile precluding conventional identification of complete serotype.

Development and validation of an LC/MS/MS method for simultaneous determination of shionone and epi-friedelinol in rat plasma for pharmacokinetic study after oral administration of Aster tataricus extract.

A rapid and sensitive liquid chromatography tandem mass spectrometry (LC/MS/MS) method was developed and validated using spinasterol as the internal standard (IS) for the simultaneous determination of shionone and epi-friedelinol in rat plasma. Plasma samples were pretreated using liquid-liquid extraction with ethyl ether. Chromatographic separation was achieved on a C18 column (100 × 2.
