| cross-transmission studies with eimeria arizonensis, e. arizonensis-like oocysts and eimeria langebarteli: host specificity at the genus and species level within the muridae. | cross-transmission experiments were done using sporulated oocysts of eimeria arizonensis from peromyscus truei and peromyscus maniculatus, and oocysts of 2 putative species that resemble e. arizonensis, i.e., eimeria albigulae from neotoma albigula, and eimeria onychomysis from onychomys leucogaster. oocysts of each species were inoculated into representatives of p. maniculatus and the latter 2 rodent species. other experiments were conducted wherein oocysts of eimeria langebarteli from peromysc ... | 1999 | 10577723 |
| eimeria from bats of the world: two new species from myotis spp. (chiroptera: vespertilionidae). | between 1986 and 1995, 548 fecal samples were collected from 41 species of bats (molossidae, mormoopidae, phyllostomidae, thyropteridae, and vespertilionidae) from new mexico, california, baja california sur (mexico), and bolivia. of these, the feces of 28 (5%) bats, including antrozous pallidus, myotis ciliolabrum, myotis lucifugus, and myotis yumanensis (vespertilionidae), contained oocysts representing at least 3 species of eimeria. a new species of eimerian from m. lucifugus (3/27, 11%) and ... | 1997 | 9194833 |
| oocyst output, periodicity, and immunity of two deer mouse (peromyscus maniculatus) eimerians (eimeria arizonensis and eimeria delicata). | we compared the life histories of 2 eimerians (eimeria arizonensis and eimeria delicata), which co-occur in the deer mouse (peromyscus maniculatus). laboratory-reared deer mice were given 10(3), 10(4) (e. delicata), or 10(3), 10(4), or 10(5) (e. arizonensis) oocysts by stomach intubation. eimeria arizonensis infections lasted longer (11-13 days) than e. delicata infections (9-10 days). eimeria arizonensis infections also produced more oocysts for each oocyst ingested at both levels compared. bot ... | 1995 | 7707193 |
| new host and locality records of coccidia (apicomplexa: eimeriidae) from rodents in the southwestern and western united states. | one hundred forty-seven murid and heteromyid rodents were collected from various sites in the southwestern and western united states (arizona, colorado, new mexico, texas, and utah) and baja california norte, mexico, and their feces were examined for coccidial parasites. of these, 53 (36%) were infected with at least 1 coccidian; 45 of 53 (85%) of the infected rodents harbored only 1 species of coccidian. infected rodents included: 10 of 22 (45%) neotoma albigula, 3 of 11 (27%) neotoma floridana ... | 1991 | 1779282 |
| cross-transmission studies with eimeria arizonensis-like oocysts (apicomplexa) in new world rodents of the genera baiomys, neotoma, onychomys, peromyscus, and reithrodontomys (muridae). | cross-transmission experiments were performed using oocysts of an eimeria arizonensis-like coccidian from peromyscus leucopus and peromyscus truei, an e. arizonensis-like coccidian from reithrodontomys fulvescens, eimeria baiomysis and eimeria taylori from baiomys taylori, eimeria albigulae from neotoma albigula, and eimeria onychomysis from onychomys spp., between representatives of the above host genera. the e. arizonensis-like coccidian from r. fulvescens infected reithrodontomys megalotis, r ... | 1992 | 1597781 |
| phylogenetic relationships among rodent eimeria species determined by plastid orf470 and nuclear 18s rdna sequences. | phylogenetic analyses for 10 rodent eimeria species from different host genera based on plastid orf470 and nuclear 18s rdna sequences were done to infer the evolutionary relationships of these rodent eimeria species and their correlation to morphology and host specificity. the phylogenies based on both data sets clearly grouped the 10 rodent eimeria species into two major lineages, which reflect more their morphological differences than host specificity. species in lineage a have spheroidal to s ... | 2001 | 11336753 |
| enzyme variation of eimeria arizonensis from peromyscus truei and p. boylii. | cricetid rodents, peromyscus truei and p. boylii, were inoculated with sporulated oocysts of eimeria arizonensis collected from wild p. truei maintained in the lab. in p. truei the prepatent period was 4-5 days, the patent period was 9-11 days, and sporulated oocysts were 21.5 x 25.0 (20-23 x 24-26) microns with sporocysts 7.7 x 12.0 (6-8 x 10-13) microns. in p. boylii the prepatent period was 6-7 days, the patent period was 8-9 days, and sporulated oocysts were 20.1 x 23.2 (18-22 x 21-24) micro ... | 2011 | 2086783 |
| population dynamics of two species of eimeria (apicomplexa: eimeriidae) in deer mice (peromyscus maniculatus): biotic and abiotic factors. | i investigated whether biotic factors (competitive exclusion between parasites and host immunity), abiotic factors (high temperature, low temperature, and rainfall), or a combination of the 2 affected the population dynamics of eimeria arizonensis and eimeria delicata in naturally infected deer mice (peromyscus maniculatus). there was no evidence of competitive exclusion between e. arizonensis and e. delicata, nor were e. arizonensis population dynamics affected by host immunity (young deer mice ... | 1996 | 8604087 |
| taxonomy and systematics of some eimeria species of murid rodents as determined by the its1 region of the ribosomal gene complex. | eimeria arizonensis, e. albigulae and e. onychomysis, morphologically similar species from closely related murid rodents, were distinguished using nuclear rdna its1 sequences obtained from multiple isolates of each taxon. its1 sequences were also obtained from 6 other species parasitizing murid rodents: e. falciformis, e. langebarteli, e. nieschulzi, e. papillata, e. separata and e. sevilletensis, and from e. reedi, a parasite of heteromyid rodents. under parsimony and maximum likelihood analyse ... | 1999 | 10581612 |
