More than 6,000 porcine reproductive and respiratory (PRRS) PCR cases were reported in October for the first time in a single month according to the Swine Health Information Center (SHIC) Domestic Disease Monitoring Report.
"This volume perhaps indicates the beginning of the PRRS season for the 2018-2019 winter," says Paul Sundberg, SHIC Executive Director.
The level of detection of porcine epidemic diarrhea virus (PEDV) by PCR continues to meet the expected value, indicating the increased detection level is within the expected for the beginning of the winter season.
Meanwhile, porcine deltacoronavirus PCR testing still has positivity above expected for the year of 2018. There was one case of E. rhusiopathiae in the 2018 fall season, and similar detection number for porcine corona virus 2, and PSV for 2018 and 2017 fall seasons.
SHIC reports two cases of pestivirus (Shaker Pig Syndrome) for fall season of 2018, which is above the same season of 2016 and 2017. Association of influenza A virus and S. suis (IAV S. suis) in respiratory tissues was more frequent in fall season of 2018 than previous years. L. intracellularis (L.intra) and Salmonellas (Salm) had increased frequency of detection in fall seasons over the recent years.
From the last report information, coccidia (COCC) continues to be a frequently detected agent, Sundberg says. All COCC cases were diagnosed as enteritis.
