Respiratory Disease (Rhinotracheitis) in Turkeys in Brittany, France, 1981-1982. I. Field Observations and Serology

During the summer of 1981, a respiratory disease epidemic occurred in turkeys in Brittany, France. Since this initial epizootic, which lasted through fall, epizootic waves similar to the initial one have occurred at approximately 6-month intervals, with smaller peaks at 2-month intervals. The epidemiology, clinical signs, and postmortem findings were highly suggestive of an epizootic of chlamydiosis. Serological tests for chlamydia, paramyxoviruses, avian influenza, adenovirus 127, mycoplasma, and Alcaligenes faecalis were conducted. The chlamydia tests were the only ones consistently positive. /// Durante el verano de 1981, una epidemia de enfermedad respiratoria ocurrió en pavos en Britania, Francia. Después de la epizootia inicial que se prolongó hasta el otoño, ondas epizoóticas similares a la inicial han ocurrido con intervalos aproximados de 6 meses y brotes menos fuertes cada dos meses. La epidemiología, los signos clínicos y los resultados de necrospsia y serológicos indicaron que se trataba de una epizootia de clamidiosis.
