The Swine Health Information Center’s (SHIC) September Domestic Swine Disease Monitoring Report is available.
This month’s Domestic Swine Disease Monitoring Report adds information on a new pathogen: Escherichia coli genotype PCR. A bonus page and podcast explain the E. coli data. PRRSV overall case positivity decreased, remaining below 20% as expected for the summer period. However, PRRSV case positivity is still above the expected levels in Iowa and Minnesota. PEDV case positivity also remains low, but in the wean-to-market category, there was a moderate increase in positive cases, raising concern for biosecurity in finishing sites. Influenza A case positivity achieved the lowest percentage (18%) since 2010, highlighting that IAV detection is below the expected levels compared with historical data. Finally, in the confirmed tissue diagnosis from Iowa State University, there was a moderate increase in the number of Sapovirus cases detected.
In the podcast, Dr. Marcelo Almeida, assistant clinical professor and diagnostician at ISU, discusses the recent E. coli PCR genotype trends, the main E. coli virotypes and pathotypes, and tips for E. coli control on farms.
