RESUMO
A case of Petriellidium boydii (synonym: Allescheria boydii) infection of the knee joint is described. It followed a penetrating soft tissue injury with a pitchfork. Such infections are rare in this country and bone involvement has not been recorded previously except in maduramycosis contracted in tropical areas.

A patient with rheumatoid arthritis treated with corticosteroids developed a septic arthritis of her right knee. She had been bitten on her right leg by her pet cat 2 weeks earlier. Pasteurella multocida, resistant to penicillin, was isolated from the septic joint and from the oropharynx of the cat. The arthritis was successfully treated with ampicillin. No attempt to eradicate the organism from the cat was made because of the expectation of early recolonisation.

In two cases of infected total hip replacements, Peptococcus magnus was isolated in pure culture from the implant when it was removed. Fluorescent antibody and ELISA studies have shown that both patients developed an antibody response to this anaerobic coccus soon after the replacement operation. These results suggest that the organism is a true infective agent, which was probably responsible for the failure of the arthroplasty operation.

The haemagglutination test for antileucocidin is frequently positive in cases of bone tuberculosis in the absence of obvious staphylococcal infection. This test is therefore of little practical use in the differentiation of staphylococcal and tuberculous bone disease, and its use has been discontinued at the Royal National Orthopaedic Hospital. The antigamma haemolysin test in bone tuberculosis appears to give rise to few false positive results. Our observations confirm that the anti-alpha haemolysin and antigamma haemolysin tests used together reveal about 80 percent of cases of staphylococcal bone infection on first presentation or relapse.
