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.

The prevalence of Mycoplasmal pneumonia and pericarditis lesions was significantly higher in pigs weaned at lower weights compared to their heavier cohorts, despite the provision of a superior production system for the lower weight group.

The reasons behind the vaccination against influenza virus on a group of fattenig units with recurrent respiratory clinical pictures that belong to an integrated production system are discussed. Impact on production parameters and economic results are also shown.

We are talking about PRRSV, M. hyo, PCV2, App and swine influenza virus.

Gilts are the population most likely to excrete M. hyo during lactation because they will probably have become infected within 200 days prior to their first farrowing.

Surrounding holdings with high hedge fences reduces the risk of airborne transmission.

Today, nearly all genetic suppliers of replacement breeding stock in North America are free of M.hyo.

Since a vast majority of commercial farms are endemically infected with M. hyopneumoniae, the control measures applied against PRRS should include measures against M. hyopneumoniae.

The cost of PRRS ranges from €17 to €185/sow/year in the three studies presented.

Estimated losses associated with M. hyopneumoniae alone and M. hyopneumoniae in combination with PRRSV were among the four health challenges with the highest estimated average loss for all pigs in the study population.

Cross-sectional sampling (different age groups during one herd visit) has the advantage that results are obtained quickly.
