faecal avoidance and selective foraging: do wild mice have the luxury to avoid faeces?host-parasite interactions are a key determinant of the population dynamics of wild animals, and behaviours that reduce parasite transmission and infection may be important for improving host fitness. while antiparasite behaviours have been demonstrated in laboratory animals and domesticated ungulates, whether these behaviours operate in the wild is poorly understood. therefore, examining antiparasite behaviours in natural populations is crucial for understanding their ecological significance. i ...024027342

autosomally determined polymorphism of glucose-6-phosphate dehydrogenase in peromyscus.glucose-6-phosphate dehydrogenase commonly occurs in at least two forms in most tissues of the deer mouse, peromyscus maniculatus, as demonstrated by starch-gel electrophoresis. an autosomally determined genetic polymorphism in one of the enzymes was discovered. a hybrid molecule occurs in the heterozygote; this suggests a dimeric structure of this enzyme.196514289612
cestode in north dakota: echinococcus in field mice.field mice (microtus pennsylvanicus and peromyscus maniculatus) are naturally infected with echinococcus multilocularis. thus, the sylvatic cycle (fox to field mice to fox) has been established in north dakota. this cestode is expected to extend its range to other agricultural regions of the continental united states where similar conditions favorable for the completion of its life cycle exist.19655891703
hexose-6-phosphate dehydrogenase found in human liver.starch-gel electrophoresis of extracts of human liver revealed the presence of a new hexose-6-phosphate dehydrogenase that was slower-moving at ph 8.6 than the sex-linked glucose-6-phosphate dehydrogenase. when the gel plate was stained, galactose-6-phos phate being used as a substrate, this enzyme band stained intensely, but the sex-linked glucose-6-phosphate dehydro genase failed to stain. this new human enzyme may well be homologous with the autosomally inherited glucose-6-phosphate dehydroge ...19665917551
