''Erysipelothrix rhusiopathiae'' is a Gram-positive, catalase-negative, rod-shaped, non-spore-forming, non-acid-fast, non-motile bacterium. The organism was first established as a human pathogen late in the nineteenth century. It may be isolated from soil, food scraps and water contaminated by infected animals. It can survive in soil for several weeks. In pig faeces, the survival period of this bacterium ranges from 1 to 5 months. It grows aerobically and anaerobically and does not contain endotoxin. Distributed worldwide, ''E. rhusiopathiae'' is primarily considered an animal pathogen, causing a disease known as erysipelas in animals (and erysipeloid in humans – see below). Turkeys and pigs are most commonly affected, but cases have been reported in other birds, sheep, fish, and reptiles. In pigs, the disease is known as "diamond skin disease." The human disease called erysipelas is not caused by ''E. rhusiopathiae'', but by various members of the genus ''Streptococcus''. It is most frequently associated as an occupational disease of butchers. ==Epidemiology== Erysipeloid is transmitted by several animals, particularly pigs, in which the disease (very common in the past) has several names (‘swine erysipelas’ in English, ‘rouget du porc’ in French and ‘mal rossino’ in Italian). Urticaria-like lesions, arthralgia⁄arthritis, endocarditis and sepsis are the most characteristic features of swine erysipelas. Other animals that can transmit the infection are sheep, rabbits, chickens, turkeys, ducks, emus, scorpion fish and lobsters. Erysipeloid is an occupational disease, mainly found in animal breeders, veterinarians, slaughterhouse workers, furriers, butchers, fishermen, fishmongers, housewives, cooks and grocers. One epidemic of erysipeloid was described in workers involved in manufacturing buttons from animal bone. The disease is of greatest prevalence and economic importance. It is economically detrimental to the pig industries of North America, Europe, Asia and Australia. True erysipeloid is usually localized to the back of one hand and ⁄ or fingers. The palms, forearms, arms, face and legs are rarely involved. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Erysipelothrix rhusiopathiae」の詳細全文を読む スポンサード リンク
