| coccidian assemblages in the wyoming ground squirrel, spermophilus elegans elegans. | one thousand nineteen wyoming ground squirrels (spermophilus elegans elegans) from 4 populations in southern wyoming were examined for intestinal parasites. the most prevalent parasites were 6 species of coccidia: eimeria beecheyi, eimeria bilamellata, eimeria callospermophili, eimeria larimerensis, eimeria morainensis, and eimeria spermophili. most ground squirrels harbored 2 or more species. this eimerian assemblage was present across populations and over years. differences in the prevalence o ... | 1992 | 1556646 |
| eimerian guilds (apicomplexa: eimeriidae) in richardson's (spermophilus richardsonii) and wyoming (spermophilus elegans) ground squirrels. | feces of richardson's ground squirrels (spermophilus richardsonii) were examined to determine occurrence and prevalence of eimerian species and to compare guilds in these hosts to previously described guilds from wyoming ground squirrels (spermophilus elegans). six species of eimeria were collected from 100 richardson's ground squirrels: eimeria beecheyi (36% infected); eimeria bilamellata (13%); eimeria callospermophili-eimeria morainensis complex (41%); eimeria lateralis (6%); and eimeria sper ... | 1993 | 8277397 |
| eimeria species (apicomplexa: eimeriidae) from arctic ground squirrels (spermophilus parryii) and red squirrels (tamiasciurus hudsonicus) in alaska and in siberia, russia. | fecal samples from arctic ground squirrels (spermophilus parryii) collected in alaska (n = 90) and russia (n = 46) and from red squirrels (tamiasciurus hudsonicus) in alaska (n = 35) were examined for the presence of eimeria spp. (apicomplexa: eimeriidae). four species were recovered from arctic ground squirrels, including eimeria callospermophili (prevalence = 18%), eimeria cynomysis (23.5%), eimeria lateralis (19%), and eimeria morainensis (77%). a single species, eimeria tamiasciuri (91%), wa ... | 2005 | 17089755 |
| a new species of subulura (nematoda: subuluroidea) from ground squirrels, spermophilus spilosoma bennett, 1833, in new mexico. | a description is presented of a new species of subulura molin, 1860, subulura novomexicanus, collected from the spotted ground squirrel, spermophilus spilosoma bennett, 1833, in new mexico. the males are 24 to 29 mm long, precloacal sucker 1.7-2.0 mm from posterior end, spicules subequal 0.83-1.0 long, and gubernaculum y-shaped 0.21-0.39 mm long. females are 34-39 mm long, vulva near middle of body 14.06-22.00 mm from anterior end, and eggs 0.04-0.05 mm long by 0.03-0.04 mm wide. the new species ... | 2007 | 18163357 |
| comparison of the its1 and its2 rdna in eimeria callospermophili (apicomplexa:eimeriidae) from sciurid rodents. | the taxonomy of the coccidia has historically been morphologically based. the purpose of this study was to establish if conspecificity of isolates of eimeria callospermophili from 4 ground-dwelling squirrel hosts (rodentia: sciuridae) is supported by comparison of rdna sequence data and to examine how this species relates to eimerian species from other sciurid hosts. eimeria callospermophili was isolated from 4 wild-caught hosts, i.e., urocitellus elegans, cynomys leucurus, marmota flaviventris ... | 2011 | 21506777 |
| two new species and temporal changes in the prevalence of eimerians in a free-living population of townsend's ground squirrels (spermophilus townsendii) in idaho. | more than 1,180 fecal samples were collected from 253 juvenile and 384 adult townsend's ground squirrels (spermophilus townsendii) at the snake river birds of prey area near boise, idaho, from february to june 1992. oocysts of 7 eimerians were observed. five are new host records (eimeria beecheyi, eimeria bilamellata, eimeria callospermophili, eimeria lateralis, and eimeria morainensis), 2 species are described here as new, and new structural information on e. morainensis is added. sporulated oo ... | 1994 | 8158469 |
