Immunolocalization of TsEla in cross-sections of different T. spiralis life stages by IFA with anti-rTsEla serum. The parasite cross-sections were probed using anti-rTsEla serum, and fluorescence staining was seen in the cuticle and stichosome of ML (a), 6 h IIL (b) and 3 d AW (c). ML cross-sections were incubated with infection sera (d) as a positive control, uninfected sera (e) and PBS (f) as negative controls. Scale-bars: 100 µm
