Abstract

An epidemiological survey was performed to evaluate the prevalence of serum antibody to Pestivirus (NADL strain of BVD/MD virus) among cattle from Pernambuco State, Brazil. Of 288 sera, 209, (72.6%) were positive. The population was stratified according to age: E = estratum - I (6 to 12 months), E-II (12 to 24 months), E-III (24 to 36 months), E-IV (over 36 months). Statistifically significant (X2; P < 0.05) differences were found between the folowing: E-I (45.4%) and E-III (78.05%); E-I and E-IV (82.7%); and E-II (60.0%) and E-IV. This indicates a positive association between age and positive infection. Moreover, statistically significant (X2; P < 0.05) difference between the rates recorde in amales (42.8%) and females (78.6%) was observed. These findings indicate a high activity of a BVD/MD (NADL) antigenically related virus.
