Brotherhood of Steam Enthusiasts. Visual Art Center; France and Switzerland. Chicken anemia virus – How is Chicken anemia virus abbreviated? The purpose of this study was to apply quantitative analytical technique to histopathology of birds infected experimentally by the virus of chicken anemia virus. Positive Pixel Count is a multipurpose algorithm that measures area and intensity of staining for two-colored slides.

The virus causes severe depletion of cortical thymocytes and erythroblastoid cells in the bone marrow, leading to immunodeficiency and anemia [ 3 ], because the VAIA lacks the necessary enzymes to reproduce its DNA in an independent way, it requires the cells to be divided very quickly [ 4 ]. Chicken anemia ifecciosa induced apoptosis: Identification of the first human gyrovirus, a virus related to chicken anemia virus. Alexis Anemka Center; est. This article has been published as part of Infeccuosa Pathology Volume 3 Supplement 1, This technique is useful as support to improve anmia histopathology evaluation making it objective by means of quantitative analytical techniques and this way, to improve the quality and efficiency of the pathology services.

Histopathology showed severe bone marrow hypoplasia to complete aplasia, fully depletion of the erythrocytic and granulocytic series, both accompanied by space occupying adipocytic replacement.

The virus causes aplastic anaemia, generalized lymphoid atrophy and increased mortality after infection of day-old susceptible chickens [ 2 ]. So, the control slides showed strong positivity, due to the presence of bigger quantity of cells of erythrocytic and granulocytic series.
