Figure 5From: Larval migration in PERL chambers as an in vitro model for percutaneous infection stimulates feeding in the canine hookworm Ancylostoma caninumFeeding of A. caninum L3 on FITC-BSA after in vitro percutaneous migration. Larvae were collected after percutaneous migration from the acceptor compartment of a PERL chamber and incubated with FITC-BSA as described for the serum-stimulation protocol. No serum was added. In contrast to the non-feeding larva above (black arrow), the positive larva (white arrow) exhibits a strong fluorescence from the gutBack to article page
