[Field study with a vaccine against enzootic pneumonia of swine].

Abstract

The EP vaccine Stellamune Myco was tested in 4 different trials. In a first trial, the daily weight increase and the incidence of lung lesions and their degree of severity were compared in non-vaccinated and vaccinated pigs originating from a herd infected with M. hyopneumoniae. The daily weight increases of the vaccinated animals were almost 60 g above that of the non-vaccinated and the number of altered lungs and the severity of the lung lesions was smaller in the vaccinated group. The effects were statistically different. In a second trial, no lesions were observed in 60% of the vaccinated animals. In the non-vaccinated group, the proportion was only about 35%. More severe lung lesions were only present in the non-vaccinated animals. In a third trial, it was observed that the animals originating from infected herds may excrete mycoplasmas despite the vaccination. In a fourth trial, it was determined that SPF piglets were not protected with the vaccination against an infection caused by M. hyopneumoniae.
