ABSTRACT
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.

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.

A respiratory disease occurred in a colony of 14 touracos in a zoological garden. Birds developed signs of disease during a period of 2 weeks and three died. Gross lesions consisted of hyperaemia of lungs, liver and kidney. An avian orthomyxovirus serotype Hav3 (or H11) was isolated. Five and 11 months after the outbreak antibodies against this serotype were present in the previously affected birds. Disease signs were not observed in another group of 14 touracos housed at the exit to the Zoo, and these birds did not contract the disease when they were moved into the building where the outbreak had taken place 4 1/2 months before. Antibodies against influenza virus were not found in these birds. It is concluded that the disease was caused by the influenza virus isolated.
ABSTRACT
The bacteriological analysis of 37 pools of cultivated soils collected in a limited area in the Parisian district permits the isolation of 14 strains of Y. pseudotuberculosis: 9 strains are of serotype II, 3 of serotype I, 1 of serotype III, and of serotype IV. This diversity contrasts with the prevalence of serotype I in infections of man and animals and the scarcity of type III and IV in these species. The abundance of our isolates is in favour of a large distribution of the germ in this substratum, which can be considered as a potential contamination source.
