WebOct 18, 2006 · We present the first clinical report of a Staphylococcus pseudintermediusinfection in a human. Biochemically, S. pseudintermediuscan be easily misidentified as S. aureus. Therefore, the final microbiological identification requires the combination of phenotypic and genotypic tests. CASE REPORT WebA The production of acetoin byS. aureusfrom glucose or pyruvate differentiates it fromS. intermedius, which is also coagulase positive. This test is also called the VP test. Acetoin production is detected by addition of 40% KOH and 1% α-naphthol to the VP test broth after 48 hours of incubation.
Weball SIG species are coagulase positive, only S. intermedius has been shown to have clumping factor (Table 1). Regardless of similar morphologies and characteristics, SIG members and S. aureus can be efficiently differentiated using a variety of biochemical tests (Table 1), including the PYR test (S. aureus negative, SIG positive) (Fig. 2C)(4). WebIdentification of S. intermedius is difficult, since S. intermedius may be misclassified as S. aureus unless specific biochemical tests are done. 14 To clearly distinguish between S. intermedius and S. aureus, differences in biochemical reactions must be used.
