Inability of so-called chicken anemia agent (CAA) infections to be diagnosed by anemia and hematopoietic organ atrophy alone
1992
Goodwin, M.A. | Brown, J.
In the recent past, anatomic and clinical pathologic diagnoses of so-called chicken anemia agent (CAA) infections have been based on lesions such as anemia and hematopoietic organ atrophy (HOA). In the present study, significant (P less than or equal to 0.05) positive and negative correlations were seen in a lesion matrix constructed from 89 cases of anemia and HOA in Georgia broilers during 1988 and 1989. Only splenic atrophy and bursal atrophy were not significantly associated. We concluded that information regarding only HOA and anemia is not sufficient to allow pathologists to diagnose CAA in broiler chickens submitted to diagnostic laboratories such as ours.
