| Pasteur effect | <biochemistry> Decrease in the rate of carbohydrate breakdown that occurs in yeast and other cells when switched from anaerobic to aerobic conditions. Results from a relatively slow flux of material through the biochemical pathways of respiration compared with those of fermentation. (18 Nov 1997) |
| Pasteur, Louis | <person> A French chemist and biologist who founded the field of bacteriology and developed the germ theory. He also invented pasteurisation and created the first vaccines against anthrax and rabies. Lived: 1822-1895. (09 Oct 1997) |
| Pasteur pipette | A cotton-plugged, glass tube drawn out to a fine tip, used for the sterile transfer of small volumes of fluid. (05 Mar 2000) |
| Pasteur's effect | The inhibition of fermentation by oxygen, first observed by Pasteur; either not observed, or only slightly observed, in malignant tumours. Compare: Crabtree effect. (05 Mar 2000) |
| Pasteur vaccine | An inactivated virus vaccine, used for preexposure immunization to persons at high risk of exposure, e.g., veterinarians, and in conjunction with rabies immunoglobulin, for postexposure prophylaxis. The official preparation is human diploid cell vaccine produced from rabies virus grown in cultures of human diploid embryo lung cells and inactivated with propriolactone. It has a much lower incidence of adverse reactions than the previously used duck embryo vaccine. (12 Dec 1998) |
