Research funded by the Swine Health Information Center has shown Actinobacillus pleuropneumoniae serotype 15 is capable of surviving colder temperatures than previously thought.Actinobacillus pleuropneumoniae is a bacterial infection that results in coughing, high fever, respiratory distress and high mortality.
In response to a severe outbreak of APP serotype 15 in finishing barns in Iowa in 2021, Iowa State University conducted a series of studies to compare different strains and define the risks posed by this emerging infection.
Swine Health Information Center Associate Director Dr. Lisa Becton says researchers looked at sows from farms that suppled pigs to outbreak locations and at finisher pigs that had gone through an outbreak.
Quote-Dr. Lisa Becton-Swine Health Information Center:
It was noted that APP 15 could survive at minus 4 degrees Fahrenheit for seven days and 72 hours at just below 40 degrees Fahrenheit.But also of note was the survivability on different surfaces such as concrete, rubber and steel with concrete being the longest at seven-day survivability.The significance of these things, it does give us a bit of insight.
