[Role of bovine respiratory syncytial virus in the aetiology of viruspneumonia in calves and yearlings ("pinkengriep") (author's transl)].
The clinical picture of "pinkengriep", an enzootic form of bronchopneumonia in young cattle, is described. In addition to cough, conjunctivitis and a soporous state, accelerated respiration initially is an outstanding clinical symptom. In some cases, symptoms of fog fever appear during the second stage of the disease. In the autumn of 1973 and that of 1974, a total number of 292 animals with "pinkengriep" were serologically examined for known respiratory virus infections and Chlamydia. Complement fixation tests showed that there was significant increase in antibodies to respiratory syncytial virus in 76 per cent of the animals studied. In the case of para-influenza virus 3, virus diarrhoea virus, the adenoviruses of the antigen groups 1, 2 and 3, those of the antigen groups 4 to 10 inclusive and Chlamydia, these proportions were 48, 13, 12, 11 en 10 per cent respectively. On the other hand, symptoms of infection with infectious bovine rhinotracheitis virus were absent in the herds studied. These findings suggest a possible role of bovine respiratory syncytial virus in "pinkengriep".
