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.

Nota de Investigación—Un coronavirus aviar en codornices con signos respiratorios y reproductivos.

Se detectó un coronavirus aviar en muestras agrupadas de pulmones, tráqueas, tractos reproductivos femeninos, riñones y contenidos intestinales de parvadas de codornices (Coturnix coturnix japónica) y de gallinas ponedoras, con la presencia o ausencia de signos clínicos sugestivos de la bronquitis infecciosa. Estas parvadas estaban alojadas conjuntamente en granjas ubicadas en dos estados del sureste de Brasil durante el período entre los años 2009 al 2010. Aunque se encontró metapneumovirus aviar subtipo B en dos muestras de ponedoras, no se encontró al virus de la enfermedad de Newcastle en las codornices ni en las gallinas. Con base en las secuencias de ADN de la región 3′no traducida y del gene que codifica a la polimerasa de ARN dependiente de ARN, este coronavirus aviar de las codornices es un virus cercano a los gammacoronavirus.
