Abstract

The investigation was conducted to detect infectious bronchitis (IB) virus-specific antibody in chicken from some selected areas of Bangladesh. The indirect enzyme linked immunosorbent assay (iELISA) was performed to estimate the infectious bronchitis virus specific antibody. In case of sera-samples collected from BRAC diagnostic laboratory, Gazipur, 100% sera samples were found to be positive to IBV; the highest antibody titres were recorded as 9867.29. The average antibody titre of samples from Anis Poultry Farm, Pabna and farms driven by beneficiary of SDC, Faridpur and layer chickens reared with the help of BEES, Hobigonj were recorded as 1234.38, 1076.94 and 4572.85 and percent of sero-positive cases were 56.67%, 43.33% and 92.50% respectively. In this study all breeds of chicken (non descriptive indigenous and commercial) and age groups were found equally susceptible to IB.
