Serological evidence of chicken anaemia virus infection in Nigerian indigenous chickens

Abstract

Serum samples from 20 out of 180 (11.1 %) apparently healthy Nigerian indigenous chickens were negative for antibodies against chicken anaemia virus using the enzyme-linked immunosorbent assay (ELISA). Of the 160 positive sera (88.9%), 12 (7.5%) had titres ranging from 1 500-3000, 46 (28.8%) had titres from 3000-5 000 while 102 (63.8%) had titres between 5000-11 000. The overall mean titre value was 5845 ±2402. This appears to be evidence of a natural outbreak of the infection since the chickens had no history of vaccination against any poultry disease.
