PloS one 9 : e Hematoxylin and Eosin stain. The infection of fibroblasts in culture is already known [ 48 ], but apparently the susceptibility to infection of these cells in vivo seems less expressive than in vitroat least at 72 hours post infection.

    In conclusion, our data suggest that YF 17DD infection of Gallus gallus embryos is mild but systemic, and affects various tissues and cells with different embryonic origins; however, not all cells are susceptible to virus infection. Then, lymphatic vessels drain these cells to lymph nodes, where the virus is replicated and released into the bloodstream, causing the first viremia [ 3811 — 13 ].

    Liver biopsy of an icteric patient shows intensely eosinophilic objects as represented by the black arrow in the photomicrograph below. Liver biopsy of an icteric patient shows intensely eosinophilic objects as shown in the photomicrograph below.

    RNA samples were extracted from formalin-fixed, paraffin-embedded tissue from the same blocks used in immunofluorescence analysis, which were either positive or negative to 17DD virus. Image shown is of Hepatits B virus.

    Studies have described the pathology and pathogenesis of YF in fatal human cases, and in experimental infections of non-human primates, golden hamsters, and mice [ 3 — 7 ].

    Abstract The yellow fever YF 17D vaccine is one of the most effective human vaccines ever created. The inoculated virus at first infects dendritic cells in the skin, which are also susceptible to virus infection in vitro and likely play an important role in infection by other flavivirus such as Dengue [ 38 — 10 ].

    Notably, amplicons in positive specimens were obtained from viral RNA using either the specific primer to the viral genome, or the replicative intermediate, indicating active replication of viral RNA Fig 9. Rita Maria Ribeiro Nogueira and Dr.

    Nested-PCR RNA samples were extracted from formalin-fixed, paraffin-embedded tissue from the same blocks used in immunofluorescence analysis, which were either positive or negative to 17DD virus. Molecular tools were performed to corroborate the specificity of our results. In this embryonic stage, gastric and respiratory epithelia were developing and showed heterogeneous cellular morphology, and sometimes apoptotic cells.
