aphid (hemiptera: aphididae) species composition and potential aphid vectors of plum pox virus in pennsylvania peach orchards.plum pox, an invasive disease recently identified in pennsylvania stone fruit orchards, is caused by the aphid-transmitted plum pox virus (genus potyvirus, family potyviridae, ppv). to identify potential vectors, we described the aphid species communities and the seasonal dynamics of the dominant aphid species within pennsylvania peach orchards. aphids were trapped weekly in 2002 and 2003 from mid-april through mid-november within two central pennsylvania orchards by using yellow and green water ...200516334309
serologic detection of herpes simplex virus type 2 antibodies among pregnant women using a point-of-care test from focus diagnostics.serologic assays that identify herpes simplex type 2 (hsv-2) type-specific antibodies have been commercially available for more than a decade. greater acceptance of these tests is hindered by uncertainty regarding their performance in real-world clinical settings.200919131273
molecular, ultrastructural, and biological characterization of pennsylvania isolates of plum pox virus.plum pox virus (ppv) was identified in pennsylvania in 1999. the outbreak was limited to a four-county region in southern pennsylvania. initial serological and molecular characterization indicated that the isolates in pennsylvania belong to the d strain of ppv. the pennsylvania isolates were characterized by sequence analysis, electron microscopy, host range, and vector transmission to determine how these isolates related to their previously studied european counterparts. genetically, pennsylvan ...201121261466
