We examined 49 Sorex cinereus, 25 S. tundrensis, 15 S. hoyi, two S. monticolus, two S. ugyunak, 19 Microtus pennsylvanicus, 45 M. oeconomus, 60 M. miurus, 13 Clethrionomys rutilus, six Synaptomys borealis collected from central and northern Alaska in August 2000 for blood parasites. Bartonella sp. was found in blood smears of 2% of S. cinereus, and Trypanosoma sp. in blood smears of 7% M. oeconomus. Meronts of Hepatozoon sp. were detected in lungs of 2% of M. oeconomus and 1.5% of M. miurus. Of possible vectors of blood parasites, species of fleas collected included Amalaraeus dissimilis dissimilis from M. miurus, Peromyscopsylla ostsibirica from S. tundrensis and M. oeconomus, and Corrodopsylla curvata curvata from S. cinereus.
