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 |
parasites of mammals on the sevilleta national wildlife refuge, socorro, new mexico: cuterebra austeni and c. neomexicana (diptera:oestridae) from neotoma and peromyscus (rodentia:muridae), 1991-1994. | in total, 6,486 rodents representing 3 families (muridae, heteromyidae, and sciuridae) and 24 species were trapped may through august of 1991 through 1994. of these, only the white-throated woodrat. neotoma albigula hartley; piñon mouse, peromyscus truei shufeldt; and white-footed mouse, p. leucopus rafinesque, were infested with cuterebra clark larvae. of the 594 n. albigula that were captured 103 (17.3%) were infested with 139 cuterebra larvae with all infestations occurring in the throat regi ... | 1997 | 9151503 |
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 |
geographical distribution of rodent-associated hantaviruses in texas. | the purpose of this study was to increase our knowledge of the geographic distribution and natural host range of hantaviruses in texas, southeastern new mexico, and mexico. blood samples from 3,225 wild rodents, representing 34 species, were tested for hantavirus antibody (igg), using an enzyme-linked immunosorbent assay. hantavirus antibody was found in one or more rodents from each of 13 counties in texas, otero county in southeastern new mexico, and mexico state (central mexico). the 133 anti ... | 2001 | 11469186 |
detection of rickettsia felis in a new world flea species, anomiopsyllus nudata (siphonaptera: ctenophthalmidae). | the flea and rodent samples studied in this project were collected from field study sites in new mexico from winter 1998 to spring 2001. during this period, 155 small rodents (14 different species) were live-trapped and combed for the presence of fleas. a total of 253 fleas were collected, comprising 21 species. two of the 253 fleas collected were polymerase chain reaction (pcr) positive for the rickettsia 17-kda protein gene. these two fleas were both anomiopsyllus nudata baker, each collected ... | 2005 | 15799525 |
catarina virus, an arenaviral species principally associated with neotoma micropus (southern plains woodrat) in texas. | the purpose of this study was to define the taxonomic relationship of an arenavirus principally associated with the southern plains woodrat (neotoma micropus) in southern texas to other new world arenaviruses. the results of independent analyses of glycoprotein precursor amino acid sequences and nucleocapsid protein amino acid sequences indicated that the arenavirus in southern texas is novel (proposed species name catarina virus) and phylogenetically most closely related to whitewater arroyo vi ... | 2007 | 17978080 |
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 |
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 |
