FIG. 2.

Titration of anti-tyvelose MAb on MDCK monolayers inoculated with biotinylated and control T. spiralis larvae. Biotinylated and control larvae were cocultured with various concentrations of MAb 9E (a) or MAb 18H (b) in overlays of confluent MDCK monolayers as described in the text. Data points are means of areas of damage to three or four monolayers. Solid symbols indicate mean area of damage caused by biotinylated larvae; open symbols indicate mean areas of damage caused by control larvae. Dashed lines show mean damage to uninfected control monolayers. Asterisks denote areas of damage which were significantly greater than those in noninfected treatment-matched control (P ≤ 0.05).
