| host preferences and temporal trends of the tick ixodes angustus in north-central alberta. | we examined host preferences and temporal trends of the tick ixodes angustus on small mammals in north-central alberta. small mammals were live-trapped from 1 june to 29 september 1994 and 3 may to 30 june 1995 in mature aspen (populus tremuloides) forest near lac la biche, alberta. abundance of female i. angustus was high in early may (0.90 +/- 0.20 [se]) and peaked again in late june (0.58 +/- 0.16), whereas abundance of immature i. angustus peaked (1.2 +/- 0.35) in mid-july. red-backed voles ... | 1998 | 9794628 |
| a new intermediate host for echinococcus multilocularis: the southern red-backed vole (myodes gapperi) in urban landscape in calgary, canada. | human alveolar echinococcosis (hae) is a potentially fatal parasitic disease caused by echinococcus multilocularis, a cestode characterized by a sylvatic life-cycle involving several species of rodents and lagomorphs as intermediate hosts and canids as definitive hosts. despite the wide distribution of the parasite in north america, the number of competent intermediate host species identified to date is still relatively small, and mainly includes the northern vole (microtus oeconomus), brown lem ... | 2013 | 23608104 |
| reservoirs of giardia spp. in southwestern alberta. | a survey of potential hosts of giardia spp. was carried out during 1982 and 1983 in the kananaskis valley and banff national park, alberta, canada. diagnosis was based mainly on fecal analysis but a few animals were examined at necropsy and scrapings from the small intestine analyzed. a total of 304 specimens was examined from humans (homo sapiens l.) and a variety of animal species. cysts and/or trophozoites of giardia were found in 10.5% of the specimens examined. positive samples were found f ... | 1984 | 6397598 |
