Detection of Avian Influenza virus Antigen in Duck by Chromatographic Immunoassay

Abstract

was found in > 30 weeks age of birds and the lowest (0%) was found in 0-10 weeks age of birds. prevalence of different age groups was also found significantly different A cross sectional study was conducted during the month October, 2009 at Khetlal and Kalai Upazilla under Joypurhat District, Bangladesh. A total of 75 cloacal swab samples of duck were collected from 25 village of 5 union of two upazilla under Joypurhat district. All the samples were examined for the detection of Avian Influenza Virus Antigen in Duck by Chromatographic Immunoassay using Anigen Rapid Avian Influenza Virus Antigen Test Kit in the laboratory of district veterinary hospital, Naogoan. A total of 1 case (6.67 %) was found positive in Ahmedabad union, 0 (0%) in Matrai union, 0 (0%) in Punot union, 2 cases (13.33%) in Borotara union and 1 (6.67%) in Bomboo union. The overall prevalence was 5.33%. Statistically a significant difference of prevalence among the areas was observed (P<0.001). Between sex the highest (6.25%) prevalence was in female and there was also a significant (P<0.05) variation between sex. Among different age group the highest (10%) prevalence . The investigation exhibited an epidemiological fact that the higher (13.66%) prevalence of avian influenza virus in duck was found around the river side union and the lowest (o %) prevalence of avian influenza virus was found in the union where there was no nearer river
