Burrough1 Abstract Swine dysentery is a severe enteric disease in pigs, which is characterized by bloody to mucoid diarrhea and associated with reduced growth performance and variable mortality. The range of manifestations of Erysipelas seen mean that clinical presentation can vary. Virulence can increase in a single passage through pigs. J Clin Microbiol.36(1):86-9. A previously unreported condition in the United States, porcine dermatitisand nephropathy syndrome (PDNS), has been described in growing pigs in Michigan.PDNS has low morbidity--less than 1% of the pigs affected--but a high mortalityrate. Individuals with acute SE will shed large quantities into the environment, and those with the chronic form are a long-term source of contamination. Classification of Zoonoses. The disease causes high mortality in swine. Treatment by oral and intramuscular penicillin is effective. Sick piglets are febrile, breathe rapidly, and may have congested or cyanotic extremities. Swine erysipelas, when uncontrolled, is economically significant and capable of affecting all stages of pork production. A variety of cells participate in cytokine storm induction and progression, with profiles of cytokines released during cytokine storm varying from disease to disease. 95.

In this study, the complete genome sequence of the E. rhusiopathiae strain WH13013, a pathogenic isolate from a diseased pig, was generated using a combined strategy of PacBio RSII and Illumina sequencing … 1992).
Ingestion of contaminated feed and water usually allows E. rhusiopathiae to gain access to the body, probably through the tonsils or other lymphoid tissue of the digestive tract (the organism often can be cultured from tonsils of normal swine). Dr. Richard Wood (Retired, National Animal Disease Center, USDA, Ames, Iowa USA) presented a history of erysipelas in domestic animals (swine), and an overview of E. rhusiopathiae identification and disease manifestations. It may be clinically inapparent, may cause acute illness involving many animals, or be a chronic disease characterized by enlarged joints, lameness, and endocarditis. Rhomboid skin (diamond-skin) lesions are an inconsistent feature only associated with acute cases. Erysipelas occurs in swine, lambs and turkeys.
Conference attendees debated the presence of superficial dermal necrosis and bacteria within dermal vessels. In chronic cases the organism can be difficult to isolate and serology may be useful.
