Patient history, clinical signs and microbiological investigations are necessary during workup, but the diagnosis can be . • Animal-to-human transmission occurs by direct cutaneous contact (via scratches or puncture wounds). This study aimed to monitor immune responses during ER infection of naïve chickens and chickens vaccinated intra muscularly with a commercial inactivated ER vaccine. 1.Several of the inoculated birds showed clinical symptoms of erysipelas, such as pale combs and fatigue on day 3, 4 and 5 after inoculation.

As this bacterium has been isolated from the poultry red mite (Dermanyssus gallinae), this parasite has been suggested as a possible means of transmission of E. rhusiopathiae on and between poultry farms. Disease has been specifically reported in Free-ranging populations of:: Northern shoveler Anas clypeata, Common merganser Mergus merganser, Anas crecca Green-winged teal (B15, B36.12.w12).. n Bears. It causes three major forms of disease in humans: erysipeloid (localized cutaneous infection), diffuse cutaneous infection, and systemic infection (bacteremia with or without endocarditis).
The organism was first identified as a human pathogen late in the nineteenth century, causing erisipeloid, a generalized cutaneous form, as well as a septicemic form often associated with endocarditis.
