A retrospective study was conducted to evaluate the temporal relationship between flock seroconversion hemorrhagic enteritis virus (HEV) and appearance of adenoviral inclusions in spleen renal tubular epithelium. The on samples turkey poults submitted Fresno Branch California Veterinary Diagnostic Laboratory System during May December 1988. included 78 submissions (four eight per submission) ages ranging from 6 15 weeks. Sera were tested for antibodies HEV using agar gel immunodiffusion test. Spleen kidney examined by light microscopy presence mononuclear phagocytes or epithelium kidney. Logistic regression statistical analysis used association age bird likelihood kidney, as well HEV. significant (P less than 0.05) found splenic inclusion bodies bird. probability higher younger birds (6 weeks age), decreased became older, approaching zero at 11 age. significantly associated with detecting increased age, reached a maximum 10 weeks, then declined, 14 However, up remained positive throughout remainder period.
