Long-lasting nosocomial persistence of chlorhexidine-resistant Serratia marcescens in a veterinary hospital.

Healthcare-associated infections (HAIs) are often overlooked in veterinary medicine. Serratia marcescens isolates were recovered over a ten-year period from companion animals in a French veterinary hospital. The pets were sampled either for diagnostic purposes or to monitor colonization.

The roles of membrane estrogen receptor subtypes in modulating dopamine transporters in PC-12 cells.

The effects of 17beta-estradiol (E(2)) on dopamine (DA) transport could explain gender and life-stage differences in the incidence of some neurological disorders. We tested the effects of E(2) at physiological concentrations on DA efflux in nerve growth factor-differentiated rat pheochromocytoma cells that express estrogen receptors (ER) alpha, ERbeta, and G-protein coupled receptor 30 (GPR30), and DA transporter (DAT). DAT efflux was determined as the transporter-specific loss of (3)H-DA from pre-loaded cells; a 9-15 min 10(-9 )M E(2) treatment caused maximal DA efflux.
