| serologic evidence of exposure of wild mammals to flaviviruses in the central and eastern united states. | serosurveys were conducted to obtain flavivirus and west nile virus (wnv) seroprevalence data from mammals. sera from 513 small- and medium-sized mammals collected during late summer and fall 2003 from colorado, louisiana, new york, ohio, and pennsylvania were screened for flavivirus-specific antibodies. sera samples containing antibody to flaviviruses were screened for wnv-specific antibodies by epitope-blocking enzyme-linked immunosorbent assays and confirmed with plaque reduction neutralizati ... | 2005 | 15891139 |
| species of eimeria (apicomplexa: eimeriidae) from tree squirrels (sciurus niger) (rodentia: sciuridae) and analysis of the its1, its2, and 5.8s rdna. | during the winter of 2004, 48 fecal samples were collected from live-trapped fox squirrels (sciurus niger) from central wyoming (natrona county) and examined for species of eimeria. two species, eimeria lancasterensis (prevalence, 65%) and eimeria ontarioensis (prevalence, 27%), were identified. genomic dna sequences its1 and its2 were amplified, cloned, and sequenced. additional sequences from e. lancasterensis isolated from a delmarva fox squirrel (sciurus niger cinereus) collected on chincote ... | 2009 | 19245280 |
| antibodies to west nile virus in raccoons and other wild peridomestic mammals in iowa. | surveillance for evidence of west nile virus (wnv) infection in small- and medium-sized wild mammals was conducted in iowa, usa, from may 2005 to june 2007. sera were collected from 325 mammals belonging to nine species and tested for antibodies to wnv and other flaviviruses by epitope-blocking enzyme-linked immunosorbent assay (elisa). all sera that had antibodies to flaviviruses by blocking elisa were further examined by plaque reduction neutralization test (prnt). thirteen mammals were seropo ... | 2009 | 19901390 |
