Chicken anemia virus and avian gyrovirus 2 as contaminants in poultry vaccines. Therefore, it can be used as support to the histopathology of field samples to evaluate the presence of lesions taken place by CAV and this way to improve the quality and efficiency of the veterinary pathology services.

A quantitative analytical technique by Positive Pixel Count Algorithm was applied.

Acknowledgements This article has been published as part of Diagnostic Pathology Volume 3 Supplement 1, Colegio de Arquitectos de Venezuela Spanish: Journal List Diagn Pathol v. The virus causes aplastic anaemia, generalized lymphoid atrophy and increased mortality after infection of day-old susceptible chickens [ 2 ].

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.

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. This is useful for measuring positivity as a infeccioas of total stained area.
