Comprehensive and rapid real-time PCR analysis of 21 foodborne outbreaks.

A set of four duplex SYBR Green I PCR (SG-PCR) assay combined with DNA extraction using QIAamp DNA Stool Mini kit was evaluated for the detection of foodborne bacteria from 21 foodborne outbreaks. The causative pathogens were detected in almost all cases in 2 hours or less. The first run was for the detection of 8 main foodborne pathogens in 5 stool specimens within 2 hours and the second run was for the detection of other unusual suspect pathogens within a further 45 minutes.

Nonlinear intestinal pharmacokinetics of mitemcinal, the first acid-resistant non-peptide motilin receptor agonist, in rats.

The objective was to investigate the mechanism of nonlinear pharmacokinetics of mitemcinal, the first acid-resistant non-peptide motilin agonist, in rats. Super-proportional increases of the cumulative rates of radioactivity excreted into bile and urine following oral administration of [3H]-mitemcinal suggested nonlinear absorption of mitemcinal in rats. To evaluate the fraction dose absorbed (Fa) and intestinal availability (Fg), [3H]-mitemcinal was orally administrated to rats, and tritium radioactivity and unchanged mitemcinal concentration were determined in the portal blood.
