title: Giardia lamblia attachment force is insensitive to surface treatments.
abstract: Giardia lamblia cell populations show 90% detachment from glass under normal forces of 2.43+/-0.33 nN applied by centrifugation. Detachment forces were not significantly different for cells attached to positively charged, hydrophobic, or inert surfaces than for cells attached to plain glass. The insensitivity of attachment force to surface treatment is consistent with a suction-based mechanism of attachment.
