Ewe abortion and neonatal mortality are serious problems to sheep farmer. The objective of this paper was to report isolation of Erysipelothrix rhusiopathiae from aborted fetuses in a flock in Tehran, Iran. Abortion occurred in 10% of ewes in the flock. The fetuses were well developed and pinpoint, necrotic-like lesions were recorded on the placental cotyledons, whilst the inter -cotyledonary a...

Erysipelothrix rhusiopathiae is a pathogen of zoonosis often associated with occupational exposure. Although Erysipelothrix rhusiopathiae infection has high mortality, the heart valves in humans are rarely involved. The clinical data of a case of a 65-year-old male with Erysipelothrix rhusiopathiae-induced aortic valve endocarditis was summarized retrospectively and analyzed with a literature r...

Erysipelothrix rhusiopathiae is a gram-positive rod capable of causing erysipelas in swine. To establish a method for specifically detecting E. rhusiopathiae for practical applications, such as for the inspection of slaughterhouses, the feasibility of using primers derived from the DNA sequence coding for 16S rRNA in a PCR-specific detection system was investigated. Oligonucleotide primers were...

The aim of this study was to characterize Erysipelothrix sp. isolates from clinically affected pigs and their environment and compare them to the Erysipelothrix sp. vaccines used at the sites. Samples were collected during swine erysipelas outbreaks in vaccinated pigs in six Midwest United States swine operations from 2007 to 2009. Pig tissue samples were collected from 1 to 3 pigs from each si...

For many years, Erysipelothrix rhusiopathiae has been known to be the causative agent of the occupationally related infection erysipeloid. A survey of the distribution of Erysipelothrix spp. in 19 Australasian seafoods was conducted, and methodologies for the detection of Erysipelothrix spp. were evaluated. Twenty-one Erysipelothrix spp. were isolated from 52 seafood parts. Primary isolation of...

Erysipelothrix rhusiopathiae is a Gram-positive bacillus that causes infections primarily in animals. In humans, this bacterium usually causes localized cutaneous infections called erysipeloid. Here we report a case of pneumonia with isolation of E. rhusiopathiae from bronchoalveolar lavage and sputum. To our knowledge, this is the first report of a pneumonia case caused by E. rhusiopathiae con...

BACKGROUND Erysipelothrix rhusiopathiae (E. rhusiopathiae) is generally transmitted into the gastrointestinal tract of animals by the intake of contaminated food or water and causes great economic loss in agriculture worldwide. Some of the Erysipelothrix spp. are the causative agents of erysipeloid, which is an occupational infection in humans. The aim of the present study was to isolate E. rhu...

Erysipelothrix rhusiopathiae (E. rhusiopathiae) septicemia was demonstrated in a captive Laughing kookaburra (Dacelo novaeguineae). The bird died after a 2-week period of weakness and weight loss. At necropsy, the bird was emaciated and had reddened and wet lungs. Microscopic lesions were limited to hepatic and pulmonary congestion with focal thrombosis. Erysipelothrix rhusiopathiae was isolate...

We have previously described the creation by Tn916 mutagenesis of avirulent transposition mutants from a highly virulent strain of Erysipelothrix rhusiopathiae, the causative agent of swine erysipelas. In this study, we cloned a 2.2-kb DNA fragment which flanked the Tn916 insertion in an avirulent mutant (strain 33H6) and evaluated the possibility that this region could be used for the specific...
