The Swine Health Information Center reports outbreaks of Strep zoo, which caused high mortality in the United States, were caused by different strains of the bacteria. Streptococcus zooepidemicus, a bacterial infection which results in the sudden death of pigs, was identified in Canada in March 2019 and has since been found in several U.S. states, including outbreaks in 2019 in Ohio and Tennessee and in January, 2021 in Indiana.
The outbreaks prompted the Swine Health Information Center to fund a project conducted at Iowa State University and the National Veterinary Services Laboratory to provide more information.
SHIC Executive Director Dr. Paul Sundberg says the infection in Indian wasn't as severe as the one in Tennessee and Ohio and although both were identified as Strep zoo, they had different sequences.
