| 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 |
| antibodies to tacaribe serocomplex viruses (family arenaviridae, genus arenavirus) in cricetid rodents from new mexico, texas, and mexico. | blood samples from 4893 cricetid rodents were tested for antibody (immunoglobulin g) to whitewater arroyo virus and amaparí virus to extend our knowledge of the natural host range and geographical distribution of tacaribe serocomplex viruses in north america. antibodies to arenaviruses were found in northern pygmy mice (baiomys taylori), woodrats (neotoma spp.), northern grasshopper mice (onychomys leucogaster), oryzomys (oryzomys spp.), deermice (megadontomys nelsoni and peromyscus spp.), harve ... | 2010 | 20795917 |
| a new eimeria species (apicomplexa: eimeriidae) infecting onychomys species (rodentia: muridae) in new mexico and arizona. | fecal samples from 3 species of onychomys (rodentia: muridae) captured in new mexico and arizona were examined for coccidia. six of the 59 (10%) were infected with a new species of eimeria. sporulated oocysts (n = 105) of this new species are subspheroidal, 17.4 x 16.1 (14-21 x 13-19) microm, with ellipsoidal sporocysts 10.4 x 5.7 (9-12 x 5-8) microm. this species occurred in 3 of 24 (13%) onychomys arenicola, 2 of 31 (6%) onychomys leucogaster from new mexico, and 1 of 4 (25%) onychomys torridu ... | 1998 | 9920315 |
| small mammal survival and trapability in mark-recapture monitoring programs for hantavirus. | following the 1993 hantavirus pulmonary syndrome (hps) epidemic in the south-western united states, mammalogists and epidemiologists instituted long-term studies to monitor population density and prevalence of infection in rodents which constitute the reservoir for sin nombre virus (snv). in this study, field techniques used in sampling small mammals for snv infection were evaluated to determine if trapping and handling protocols were having significant effects on future trapability or mortality ... | 1998 | 9476220 |
| helminths of sympatric populations of kangaroo rats (dipodomys ordii) and grasshopper mice (onychomys leucogaster) from the high plains of eastern new mexico. | during a 1-yr period 124 dipodomys ordii and 92 onychomys leucogaster were trapped from the same locality and were examined for helminths. only 1 cestode species (catenotaenia linsdalei) was recovered from d. ordii, whereas o. leucogaster was infected with 2 nematoda (litomosoides carinii, mastophorus muris), 2 cestoda (hymenolepis citelli, and 1 unknown), and 1 acanthocephalan (moniliformis clarki) species. all represent new host and distribution records. | 1985 | 4057002 |
