Abstract

An Avian coronavirus was detected in pools of lungs, tracheas, female reproductive tracts, kidneys, and enteric contents from quail (Coturnix coturnix japonica) and laying hen flocks, with and without infectious bronchitis (IB)-like signs, cohoused in farms located in two states of southeastern Brazil during 2009-2010. Although Avian metapneumovirus subtype B was found in two layers samples, Newcastle disease virus was not found in quail or in hens. Based on DNA sequences for the 3'-untranslated region and the gene encoding the RNA-dependent RNA polymerase, this avian coronaviruses in quail is an IB virus-like gammacoronavirus.

摘要

2009年至2010年期间，在巴西东南部两个州的农场中，对鹌鹑（日本鹌鹑）和蛋鸡群的肺、气管、雌性生殖道、肾脏及肠道内容物样本进行检测，发现了一种禽冠状病毒，这些鸡群有或没有类似传染性支气管炎（IB）的症状。尽管在两份蛋鸡样本中发现了禽偏肺病毒B亚型，但在鹌鹑或母鸡中未发现新城疫病毒。根据3'-非翻译区和编码RNA依赖性RNA聚合酶的基因的DNA序列，鹌鹑体内的这种禽冠状病毒是一种类似传染性支气管炎病毒的γ冠状病毒。
