초록

연구는 방글라데시에서 조류인플루엔자와 뉴캐슬 질병 바이러스가 국내의 현장 샘플에서 혼합항원키트의 민감도와 특이성을 평가하기 위하여 육계 및 산란계와 토종 닭 그리고 사육 야생오리, 거위, 비둘기와 메추라기로부터 야외 샘플을 수집하였다. 샘플은 방글라데시의 5 지역에서 발생한 조류인플루엔자 자연감염된 것으로 의심되는 닭과 야생사육조수로부터 수집되었다. 각 지역으로부터 2마리씩 선택적으로 샘플을 수집하였으며, 각 조류에서는 면봉을 이용하여 기도, 총배설강, 구-비강으로부터 3가지 유형의 샘플을 채취하였다. 70 마리의 조류에서 총210개의 야외 샘플이 수집되었으며, 조류인플레인자와 뉴캣슬병 바이러스 혼합항원신속진단키트를 검사하였다. 210개 샘플 중에서 15개(5 마리)가 조류인플루엔자 바이러스, 63개(21 마리)가 뉴캣슬병 바이러스, 27개(9 마리)에서 두 가지의 혼합감염이 나 타났으며, 그 외에서는 모두 음성으로 나타났다. 5 곳의 조류인플루엔자 양성 중에서 Mymensingh, Netrokona, Gibandha와 Kurigram의 마켓으로부터 산란계에서, Kurigram의 마켓에서 토종닭에서 양성이 나타났다. 야생사육조수는 뉴캣슬병에 양성이거나 또는 조류인플루엔자와 뉴캣슬병 바이러스에는 감염되지 않았다. 조류인플루엔자 및 뉴캣슬병 바이러스 신속진단키트로 기도, 총배설강, 구-비강으로부터 채집한 샘플에서 동시에 검출할 수 있는 것으로서 효과적으로 사용될 것으로 평가되었다. 조류인플레인자와 뉴캣슬병 바이러스 혼합 항원 검사 결과는 명확히 두 개의 바이러스 검출을 위한 테스트 키트로서 적은 노력과 대규모의 필드 샘플로부터 이들 바이러스의 검출에 효과적으로 사용될 수 있는 최신의 과학적 방법이며, 신속하게 질병을 진단할 수 있었다.

The study was undertaken to evaluate sensitivity and specificity of rapid Avian Influenza (AI) and Newcastle Disease virus (NDV) combo antigen kits from field samples of domestic (broiler and layer chicken, native chicken) and semi-domestic (duck, goose, pigeon and quail) birds of Bangladesh. Samples were collected from naturally infected AI suspected domestic and semi-domestic birds of five different outbreak areas in Bangladesh. From each area two birds were selected for sampling, and from each bird three types of samples (tracheal, cloacal and oro-nasal swabs) were collected. A total of 210 field samples from a total of 70 birds were collected and tested using AI and NDV combo antigen rapid diagnostic kits in the study. All three different samples from a bird showed similar pattern of reaction. Out of 210 samples, 15 samples (5 birds), 63 samples (21 birds) and 27 samples (9 birds) were positive for AIV, NDV and both for AIV and NDV, respectively; whereas the remaining birds were negative for either AIV or NDV in this screening test. Among the five AIV positive, a layer chicken from wet market in Mymensingh, Netrokona, Gibandha and Kurigram and a native chicken from wet market in Kurigram area was positive to AIV. The semi-domestic birds are either positive to NDV or free from both AIV and NDV. This study revealed that the AIV and NDV rapid diagnostic kits could be effectively use to diagnose the respective virus in trachea, oro-nasal and cloacal samples simultaneously. AIV-NDV combo Ag test result clearly indicates that the test kit designed for AIV and NDV could diagnose the disease rapidly with less effort and higher scientific know how which could be used for the detection of AIV and NDV using field samples in large scale.
