Respiratory disease (Rhinotracheitis) in turkeys in Brittany, France, 1981-1982. II. Laboratory findings

After discovering that numerous turkey flocks experiencing rhinotracheitis in Brittany, France, had antibodies against chlamydia, laboratory studies were conducted to determine whether chlamydia and/or viruses would explain the respiratory disease observed. Although both lentogenic paramyxoviruses of type 1 (Newcastle disease virus) and Chlamydia psittaci were isolated, it was concluded, based on epidemiologic and other laboratory findings, that C. psittaci was the primary cause of the disease. /// Después de encontrar que numerosos lotes de payos con rinotraqueítis tenían anticuerpos contra Clamidia, se realizaron estudios de laboratorio para determinar si Clamidia o virus eran los responsables del problema respiratorio observado. Aunque se aislaron tanto cepas lentogénicas de paramixovirus tipo 1 (virus de la enfermedad de Newcastle) como Clamidia psittaci; se concluyó, basado en los resultados epidemiológicos y de laboratorio, que C. psittaci fué la causa primaria de la enfermedad.
