[Results of field studies using Stellamune mycoplasma vaccine in Luxembourg].

Enzootic pneumonia caused by Mycoplasma hyopneumoniae is responsible for major economic losses in pig herds worldwide. M. hyopneumoniae can also act as a primary agent of swine respiratory disease followed by bacterial or viral infections. Vaccines have been developed to prevent enzootic pneumoniae. In this experiment, an inactivated vaccine against mycoplasma, also sold under the name Stellamune mycoplasma (Pfizer Animal Health) was used in 2 farms with a known history of M. hyopneumoniae infection. The objective of the study was to evaluate the effect of the product on lung lesions caused by M. hyopneumoniae and on economic performance of the pigs under field conditions.
