| fox squirrels (sciurus niger) develop west nile virus viremias sufficient for infecting select mosquito species. | the west nile virus (wnv) viremia and shedding profiles of 11 adult fox squirrels (sciurus niger) infected by needle inoculation or mosquito bite were characterized. daily mean titers (95% confidence intervals) for all squirrels on days 1 through 6 postexposure (p.e.) were: 10(1.7 (1.32.1)), 10(4.4 (4.04.8)), 10(5.3 (5.05.6)), 10(4.4 (3.94.9)), 10(2.7 (2.03.4)), and 10(1.1 (0.52.1)) plaque-forming units (pfu)/ml. the highest wnv serum titers of individual squirrels infected by needle inoculation ... | 2008 | 18240969 |
