Eradicazione di M. hyopneumoniae nel suino: gli strumenti ci sono
I metodi storicamente impiegati per ridurre l’incidenza delle infezioni da M. hyopneumoniae non sembrano attualmente funzionare adeguatamente. I programmi di controllo per questo microrganismo si dividono in due macrocategorie: i programmi che prevedono l’eradicazione dell’agente patogeno e quelli che non la prevedono; a quest’ultima categoria appartengono le strategie che si basano su tre concetti: gestione, prevenzione e trattamento.
