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.

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.

[Effect of sulfuric acid vapors on the respiratory system].

The influence of a mixture of sulphuric acid vapour and SO2 mist upon the respiratory tract of animals was investigated during on exposure lasting 8 and 12 hours. Marked inflammatory changes in the upper respiratory tract, bronchioli and lung parenchyma were found. These changes were manifested by inflammatory infiltrations and abundant production of mucous in the bronchial tree. A significant increase in the number of dust cells in the lumen of bronchioli was also observed. A decrease of mitotic index was found in the epithelium of oral cavity after inhalator intoxication with sulphuric acid. This may lead to disturbances in the repair of epithelium. The authors emphasize the intensity of changes in proportion to H2SO4 dosage.

[Passive and active immunization against feline enteritis and rhinotracheitis in experimental cats (author's transl)].

The results of passive and active immunization against feline rhinotracheitis with regard to mortality and morbidity were studied in 335 cats. Passive immunization reduced mortality from pneumonia from 5 per cent to 1 per cent. Vaccination against rhinotracheitis also reduced mortality from pneumonia from 5.3 per cent to 0 per cent and markedly reduced morbidity of these conditions.
