Erysipelothrix rhusiopathiae is a Gram-positive bacillus that is infrequently responsible for infections in humans. Three forms have been classified: a localized cutaneous form (erysipeloid) caused by traumatic penetration of E. rhusiopathiae, a generalized cutaneous form and a septicemic form. The latter type of disease has been previously associated with a high incidence of endocarditis. Here...

Sodium azide-crystal violet-agar and a modified blood-azide (MBA)-agar were used to isolate Erysipelothrix rhusiopathiae from swine tissues. There was no significant difference in the number of isolations. However, 78% of the isolants from modified blood-azide medium required only 24 hr of incubation, whereas all of the isolants obtained on sodium azide-crystal violet medium required 48 hr.

Over the past decades, Erysipelothrix rhusiopathiae strains displaying similar phenotypic and genetic profiles of the attenuated, acriflavine-resistant E. rhusiopathiae Koganei 65-0.15 strain (serovar 1a) have been frequently isolated from pigs affected with chronic erysipelas in Japan. In this study, using the conventional PCR assay that was designed to detect strain-specific single nucleotide...

Erysipelothrix rhusiopathiae is a Gram-positive bacillus that causes infections primarily in animals. In humans, the bacteria usually cause localized or generalized cutaneous infections. A 75-year-old man with chronic alcoholism presented with abdominal pain. Abdominal computed tomography and laboratory findings suggested an intra-abdominal abscess in the periaortic soft tissue. While no defini...

Few reports are found in the literature concerning the use of aureomycin in animal disease therapy. McCullough, Kiser, and Migaki (1949) and Easterbrooks (1950) have reported beneficial results in the treatment of staphylococcic mastitis of cattle. Prier (1950) reported that aureomycin was effective in the treatment of experimental Pasteurelka multocida infections of chickens. Little (1948) rep...

Coagulase activity was detected in 99% of 225 strains of Erysipelothrix rhusiopathiae. These strains included isolates from a variety of animal and environmental sources. Activity could be detected by the tube or slide technique, with the tube reactions being easier to interpret. Coagulation of rabbit and/or bovine plasma was observed, with most strains reacting in both. The activity appeared t...
