Microbiologic evaluation of XXXX in adults.

@entity1 @entity281 @entity2688
Fifty @entity1 with @entity2688 were evaluated prospectively using cultures of aspirates from the advancing edge of @entity2688 , skin biopsy specimens, and blood. Potential microbial pathogens were isolated in 13 @entity1 . Biopsy specimen cultures were positive in ten @entity1 , while aspirate and blood cultures were positive in five and two, respectively. Aspirate, biopsy, or blood cultures were more often positive in @entity1 with apparent primary lesions than in @entity1 without such lesions. Apparent primary sites of @entity281 were identified and cultured in 24 @entity1 . beta-Hemolytic streptococci were isolated from 17 primary lesions, and coagulase-positive staphylococci were present in 13. Both organisms were isolated from ten primary lesions. Among @entity1 with positive aspirate, biopsy, and/or blood cultures, the same pathogens were also isolated from primary sites in ten of ten @entity1 . Clinical features, including temperature, white blood cell count, and erythrocyte sedimentation rate, were not predictive of positive aspirate, biopsy, or blood cultures. These cultures provided no microbiologic information that was not obtainable from culture of primary lesions.
