Invasive infection with animal-associated bacteria, Erysipelotrix rhusiopathiae, is unusual and has, to our knowledge, never been described as the cause of infected total hip arthroplasty. We describe how an infected total hip arthroplasty caused by these bacteria is eradicated using standard surgical and antibiotic treatment. Before 2-stage revision surgery, the patient had persistent groin pain, elevated C-reactive protein, radiographic periprosthetic osteolysis, excessive intra-articular fluid, and periprosthetic activity accumulation on the white cell scan. The patient was treated with benzylpenicillin after confirmed sensitivity of E rhusiopathiae diagnosed by culture of five tissue samples and polymerase chain reaction of the prosthetic sonicate sample. Sixteen weeks after the last stage of revision surgery, there were no signs of reoccurring infection.
"Rarely septic arthritis and other serious systemic complications like septicaemia and endocarditis can occur  . To our knowledge, all reported cases of septic arthritis caused by E. rhusiopathiae so far are in adults        . We report a case of septic arthritis of the hip in a child caused by this organism. "
[Show abstract][Hide abstract] ABSTRACT: Erysipelothrix rhusiopathiae is an established animal pathogen while the zoonotic infections in humans are rarely reported. Infections occur after exposure to animals or animal products that are mostly occupational in adults. Here we report in a child for the first time septic arthritis and osteomyelitis without an identifiable risk factor. A 5-year-old male child was admitted with pain in the left hip joint and inability to bear weight on the limb. Clinical examination followed by radiological and magnetic resonance imaging was suggestive of septic arthritis. Erysipelothrix rhusiopathiae grew from peroperative joint specimen. The infection was resolved following arthrotomy, joint lavage and antibiotic therapy.

[Show abstract][Hide abstract] ABSTRACT: We describe the third case of prosthetic infection due to Erysipelothrix rhusiopathiae. The patient, a 68-year-old woman, had had total knee arthroplasty 12 months before diagnosis. She had been in contact with
swine at home. We review the seven previous reports of septic arthritis due to E. rhusiopathiae.
[Show abstract][Hide abstract] ABSTRACT: This report describes two cases of cutaneous cellulitis in workers at the same poultry farm in the rural area of Tandil, Argentina. In both patients E. rhusiopathiae was identified from culture samples obtained through biopsy. Investigation of the reservoir showed that in all samples of fowl waste and in 2 samples of feed E. rhusiopathiae was isolated with identical biochemical and antibiotic resistance profiles to those of the isolated strains in the case reports. Even though molecular analyses are required to establish an epidemiologic relation between the strains found in the patients and those in the farm, it can be inferred that the source of the human infection was the extensive poultry farm.
