Objective: This study was carried out to investigste the
seroprevalence of Avian Pneumovirus infection in broiler
breeder farms which were located in Urmia city by using
the enzyme-linked immunosorbent assay (ELISA).
Design: A field survey.
Animal: Brioler breeder chickens. Procedure: In this study, 552 blood samples were taken
from 39 broiler breeder flocks. The broiler breeder flocks
were categorized in three age groups: 0-20, 2 1-35 and 36-
55 weeks old. Serum samples were tested for Avian
Pneumovirus antibodies by using a commercial blocking
ELISA kit.
Statistical analysis: Descriptive statistics.
Results: The results of this study showed,207(37%) of
serum samples were positive and 192 (35%) ones were
negative. Furthermore, 153 (28%) of samples were
suspected. Clinical implications: Based on these findings, it can be
concluded that broiler breeder farms which are located in
Uremia city, are serologically positive in regard to Avian
Pneumovirus infections. Since AVP has economical
importance in poultry industry by inducing respiratory
disease, the prevalence of AVP in prevention and control
programs of respiratory diseases has to be highly
considered. J.Fac. Vet. Med. Univ. Tehran. 61,2:129-
