Estimates of prevalence and sensitivity from model 1 at the sample level, using 4 testing methods for the isolation of methicillin-resistant Staphylococcus pseudintermedius from clinical specimens (n = 741).

	Prevalence (%)	Sensitivity (%)
Traditional	10.1 (8.1–12.5)	74.9 (64.2–83.2)
MSAox	8.9 (7.1–11.2)	66.4 (56.1–75.3)
EB with MSAox	11.2 (9.1–13.7)	84.0 (75.0–90.1)
EB with traditional	10.8 (8.8–13.2)	80.8 (71.6–87.6)
Overall	13.4 (11.1–16.0)	100.0*

Numbers in parentheses are 95% confidence intervals. EB with MSAox = enrichment broth with mannitol salt agar with 2 µg/mL of oxacillin; EB with traditional = EB with routine diagnostic method; MSAox = mannitol salt agar with 2 µg/mL of oxacillin; Overall = a positive test result on any 1 of the 4 test methods; Traditional = routine diagnostic method.

^*The overall method was used as the reference for positive samples.
