Exposure methods: natural, intranasal, intra-tracheal, aerosol or vaccination.

Intranasal and intratracheal inoculation routes as well as aerosolization with foggers are discussed.

Traditional gilt exposure to seeder animals is being substituted by intratracheal inoculation and aerosol exposure.

The farmer contacted the veterinary surgeon concerning an increase of respiratory distress and mortality in the finishing pigs during the previous 3 days.

Establishing Day 0 is a crucial step in disease control and elimination programs and should be carefully performed by swine health professionals.

Some of the take-home messages of this article are: M. hyo transmits slowly within exposed populations, but pigs can shed for long periods of time.

Gilt acclimation was performed in 78% surveyed European farms; vaccination, alone or combined with natural exposure to infected animals, was the main used strategy.

Three factors must be taken into account when defining the viability of the elimination of M. hyopneumoniae on each farm: negative replacements, cost and return on investment, and risk of re-infection.

No single strategy will confer total protection. A well-orchestrated combination of various methods adjusted to a single production unit or system will be needed.

Enric Marco discusses a trial that concludes that the later the infection by M. hyorhinis occurs, the less serious it is. This information can be very useful to devise new control strategies in the era of antibiotic reduction.
