Light microscope analysis of haemozoin-like pigments in parasitic-stage Haemonchus contortus. Parasitic fourth-stage larvae (L4s) and adult worms were collected from the infected goat’s abomasa at days 7 and 28 post-infection, respectively. A Representative light microscope images showing the haemozoin-like pigments in L4s and adult worms. B Representative light microscope images showing ferric iron stain (green) in L4s and adult worms. The intestinal tissues are outlined by dotted lines. Three independent replicates were performed with similar results. Scale bar = 200 μm. Int, intestine
