| 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 |
| modoc-like virus isolated from wild deer mice (peromyscus maniculatus) in alberta. | small mammals were trapped in northeastern alberta, canada during 1976. blood samples from these animals were tested for virus by inoculation of suckling mice. blood clots from two deer mice yielded isolates of the same virus. the virus was related antigenically to a number of flaviviruses which have been isolated from mammals in central america and north america and was related most closely to modoc virus. physical, chemical, and biological properties of the virus were similar also to those of ... | 1985 | 2987550 |
| adiaspiromycosis in the franklin's ground squirrel, spermophilus franklini, and pika, ochotona princeps, from alberta, canada. | pulmonary adiaspiromycosis due to emmonsia crescens was diagnosed in three of six franklin's ground squirrels (spermophilus franklini) captured in rochester, central alberts, canada in the summer of 1971, and in one of 240 pikas (ochotona princeps) collected in southwestern alberta in 1969. granulomas measuring 0.5 to 1 mm in diameter were found in both lungs. these granulomas contained adiaspores measuring 60 to 400 mum in diameter. the disease was not found in six franklin's ground squirrels c ... | 1976 | 943581 |
| 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 |
| 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 |
| small mammals as sentinels of oil sands related contaminants and health effects in northeastern alberta, canada. | the extraction of bitumen in areas of northeastern alberta (canada) has been associated with the release of complex mixtures of metals, metalloids, and polycyclic aromatic compounds (pacs) to the environment. to mitigate effects on ecosystems, canadian legislation mandates that disturbed areas be reclaimed to an ecologically sustainable state after active operations. however, as part of reclamation activities, exposure to, and effects on wildlife living in these areas is not generally assessed. ... | 2016 | 26555251 |
