[Possibilities for the establishment of pneumonia-free swine herds by immunization and administration of cefquinome].

The application of Bordetella and Pasteurella inactivated and adsorbed vaccines together with cefquinome to sows, piglets and weaners led to a significant reduction of the incidence of rhinitis atrophicans and pneumonia. The frequency of positive isolates of P. multocida, H. parasuis and A. pleuropneumoniae out of nasal swabs was reduced during the treatment.
