Avidin does not protect MDCK monolayers from invasion by biotinylated T. spiralis L1 larvae

Treatment	Damage to monolayer (mm2, 103)a by:
	Uninfected control	Biotinylated larvae	Control larvae
Medium	9 ± 2	56 ± 17b	30 ± 9c
Avidin
1.0 mg/ml	8 ± 1	27 ± 4	32 ± 6
0.5 mg/ml		34 ± 3	32 ± 1
0.25 mg/ml		40 ± 6	26 ± 4
0.125 mg/ml		38 ± 11	28 ± 11

^aDamage to monolayer expressed as mean ± 1SD; n = 3 or 4 monolayers. 

^bMean was not significantly different from means of damage by avidin-treated biotinylated larvae. 

^cMean was not significantly different from means of damage by avidin-treated control larvae.
