| 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 |
| prevalence of antibodies to arenaviruses in rodents from the southern and western united states: evidence for an arenavirus associated with the genus neotoma. | the objectives of this study were to extend our knowledge of the geographic distribution and rodent host range of arenaviruses in north america. sera from wild rodents collected from the southern and western united states were tested for antibody against tamiami, pichinde, junin, and lymphocytic choriomeningitis viruses, using an indirect fluorescent antibody test. antibody to at least one arenavirus was found in 220 (3.1%) of 7,106 rodents tested. the antibody-positive animals included mus musc ... | 1996 | 8686773 |
| short report: a focus of leishmania mexicana near tucson, arizona. | twenty-eight white-throated woodrats (neotoma albigula) collected in pima county, arizona were screened for leishmania using culture and the polymerase chain reaction (pcr). two rodents were culture positive. isoenzyme analysis determined the isolates to be leishmania mexicana. the two culture-positive and four additional rodents were determined to be leishmania-positive by the pcr. these isolates extend the geographic and ecologic range of enzootic leishmaniasis in the united states and represe ... | 1999 | 10497974 |
| diversity among tacaribe serocomplex viruses (family arenaviridae) naturally associated with the mexican woodrat (neotoma mexicana). | the results of analyses of glycoprotein precursor and nucleocapsid protein gene sequences indicated that an arenavirus isolated from a mexican woodrat (neotoma mexicana) captured in arizona is a strain of a novel species (proposed name skinner tank virus) and that arenaviruses isolated from mexican woodrats captured in colorado, new mexico, and utah are strains of whitewater arroyo virus or species phylogenetically closely related to whitewater arroyo virus. pairwise comparisons of glycoprotein ... | 2008 | 18304671 |
| epizootiology of arenaviral infections in the white-throated woodrat (muridae: sigmodontinae) and other woodrats in arizona. | the purpose of this study was to extend and refine our knowledge of the geographical distribution and natural host relationships of the arenaviruses associated with woodrats indigenous to arizona. antibody to a tacaribe serocomplex virus was found in 112 of 1,250 white-throated woodrats, five of 208 mexican woodrats, one of 114 stephen's woodrats, and none of 862 other rodents captured at 51 sites in 10 counties in arizona. of the 112 antibody-positive white-throated woodrats, 109 (97.3%) were c ... | 2004 | 15707295 |
| diversity among tacaribe serocomplex viruses (family arenaviridae) naturally associated with the white-throated woodrat (neotoma albigula) in the southwestern united states. | bayesian analyses of glycoprotein precursor and nucleocapsid protein gene sequences indicated that arenaviruses naturally associated with white-throated woodrats in central arizona are phylogenetically closely related to the whitewater arroyo virus prototype strain av 9310135, which originally was isolated from a white-throated woodrat captured in northwestern new mexico. pairwise comparisons of glycoprotein precursor and nucleocapsid protein amino acid sequences revealed extensive diversity amo ... | 2008 | 18454597 |
| occurrence of lutzomyia anthophora (diptera: psychodidae) in arizona. | males and females of lutzomyia anthophora addis were collected by vacuum aspiration from woodrat, neotoma albigula hartley, and rock squirrel, citellus variegatus bailey, nests along arivaca creek in pima county, arizona. additional flies were collected from the same location using cdc miniature light traps supplemented with co2. these collections extend the recorded geographic distribution of this vector of leishmania mexicana biagi westward by approximately 724 km and place lu. anthophora in a ... | 1995 | 7473634 |
