Developing larvae of Varestrongylus eleguneniensis at various days post-infection (dpi) at 12 °C when observed under 400× magnification. a First-stage larva at 40 dpi. b Second-stage larva at 47 dpi. c Early third-stage larva at 55 dpi. d Intermediate third-stage larva at 61 dpi. e Late third-stage larva at 67 dpi. f Emerged third-stage larva at 72 dpi. Larval stages were differentiated based on Kutz et al. [25] and Verocai et al. [20]. Scale-bars: 20 μm
