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.

Pixel counts area are calculated for strong positive Redpositive Orangeweak positive Yellowand negative Blue pixels. Histopathology showed severe bone marrow hypoplasia to complete aplasia, fully depletion of the erythrocytic and granulocytic series, both accompanied by space occupying adipocytic replacement. Centre Alexis Vautrin French: Colegio de Arquitectos de Venezuela Spanish: A sequential histopathologic and inmunocytochemical study of the chicken anemia virus infection at one day of age.
A quantitative analytical technique by Positive Pixel Count Algorithm was applied. New trends in digital pathology: Conclusion This technique demonstrated in a quantitative way the severe decrease of the cellular components of the bone marrow in presence of the infection for CAV, supporting with numeric data the histology image evaluated by the pathologist.

Centre d’Art Visuel French: Open annemia a separate window. This is useful for measuring positivity as a fraction of total stained area. 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.
