This report summarized the findings of a case of Erysipelothrix rhusiopathiae infection in a farmed Norwegian Red heifer located in the south-east of Norway. The 2.5-year-old pregnant heifer was found dead after a short episode of inappetence. On gross exam, the heifer was severely dehydrated with uterine torsion. Microscopically, necrosis of the endometrium was present throughout the uterus along with presence of intralesional Gram-positive bacteria, interstitial nephritis, and pyelonephritis. E. rhusiopathiae was isolated from the uterus and placenta and was also demonstrated by immunohistochemistry (IHC) in the uterus, placenta, and kidney. The E. rhusiopathiae isolate was further characterized as serotype 5. To the authors' knowledge, this is the first report of bacterial metritis associated with E. rhusiopathiae serotype 5 infection. The etiology of the infection is unknown but the E. rhusiopathiae could have been a primary or opportunistic pathogen. Serotype 5 of E. rhusiopathiae has been identified in several mammalian species in recent years and could be emerging.
