Avian coronavirus (AvCoV/IBV) is a virus with high morbidity, which can cause respiratory, digestive, renal, and reproductive diseases in chickens. Molecular detection and sequencing are the main tool for identification and classification of AvCoV. Thirty-six samples were collected in three broiler farms from different regions in Colombia, due to mortality increase; ten samples were positive using RT-qPCR targeted to the 5′ UTR of AvCoV, and one sample was positive and had its partial S gene sequenced. Phylogenetic analysis revealed that this strain belongs to the GI-11 lineage, similar to the Brazilian cluster. Several lineages have already been described in Colombia but, to the best of our knowledge, this is the first time that GI-11 has been detected in this country, which suggests that this subtype may be more widespread in South America than previously thought.

禽冠状病毒基因型 GI-11 在哥伦比亚出现

禽冠状病毒（AvCoV/IBV）是一种发病率很高的病毒，可引起鸡的呼吸系统、消化系统、肾脏和生殖系统疾病。分子检测和测序是鉴定和分类AvCoV的主要工具。由于死亡率增加，在哥伦比亚不同地区的三个肉鸡养殖场收集了 36 个样本；10 个样本使用针对 AvCoV 的 5' UTR 的 RT-qPCR 呈阳性，1 个样本呈阳性并对其部分 S 基因进行了测序。系统发育分析表明，该菌株属于 GI-11 谱系，类似于巴西簇。哥伦比亚已经描述了几个谱系，但据我们所知，这是该国首次发现 GI-11，
