rTsSerp facilitation or anti-rTsSerp serum suppression of larval invasion of excised intestine. One hundred IILs were pre-incubated with rTsSerp, TRX-tag, anti-rTsSerp serum, anti-TRX-tag serum or PBS, subsequently injected into excised murine intestinal lumen, and maintained in Tyrode’s solution at 37 °C for 2 h. The enteric segment was cut off, and the intestinal mucosa was compressed between two thick slides and examined under microscopy. A Non-invaded larvae were spiral coils within the enteric lumen (200 ×). B Invaded larvae were inside the intestinal mucosa (400 ×). C The invasion rate of excised intestine by larvae pre-incubated with rTsSerp or anti-rTsSerp serum. *P < 0.0001 compared to the TRX-tag, anti-TRX-tag serum or PBS group. Scale bars: 100 μm.
