TABLE 5.

Summary of defects caused by 81 extracts on biofilm architecture and PMN impenetrability in the three thickness categories^a

Category	No.	% of extracts in each category in which the following had a score of −, +, or ++:
		Presence of BYCP	Hypha formation	Vertical hypha orientation	ECM staining	PMN impenet.	Hyphal bend point	Pseudohypha formation	One or more affected parameters
Thicker	10	0	10	10	50	50	10	20	60
Thinner	25	44	20	44	52	68	36	16	84
Similar	46	10	4	20	33	37	9	7	52

^aComparisons to the untreated control were made. No., number of extracts resulting in biofilms that were thicker than the control biofilm, thinner than the control biofilm, or similar in thickness to the control biofilm. BYCP, basal yeast cell polylayer; ECM staining, staining if extracellular matrix with calcofluor white; PMN impenet., polymorphonuclear leukocyte impenetrability; hyphal bend point, the proportion of extract-treated biofilms in a category in which the bend point occurred at less than 60% of the hyphal length.
