Snippet: 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 s
Document: 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.
