TABLE 2.

Sap production by skin and blood isolates of C. parapsilosis

Source (n)	HIV status	Sap production on:
		BSA agara		BSA brothb (mean U ± SD)	Pd
		No. ++/total	Pc
Skin (7)	HIV+	7/7		3.84 ± 0.15
Skin (5)	HIV−	5/5		3.80 ± 0.17
Blood (9)	HIV−	0/9	<0.01	0.85 ± 0.07	<0.01

^aMeasured as the diameter of BSA clear zone (0, none; +, 1 to 2 mm; ++, 3 to 5 mm) (see also references 9 and 10). 

^bMean ± SD units, from the spectophotometric determination (see references 9 to 12). 

^cP < 0.01 (Fisher exact test), comparing Sap production by skin isolates (only HIV⁺ or else HIV⁺ plus HIV⁻) to that by blood isolates. 

^dP < 0.01 (Student's t test), comparing Sap production as in footnote c.
