Fig. 2 in Infestation, histology, and molecular confirmation of Sarcoptes scabiei in an Andean porcupine (Coendou quichua) from the Central Andes of Colombia

Fig. 2. Histological microphotographs of the development of the mite S. scabiei in the skin of the porcupine C. quichua. Permanent burrows dug by fertilized adult females, with the presence of a developing egg and the shell of another hatched egg (A, B). Burrows with the presence of three eggshells (sh) and feces (fe), where between two and three eggs are laid daily (C). Developing eggs within burrows in the stratum corneum of the skin, which hatch approximately 3–4 days after oviposition (D–F). Developing larvae in the superficial layer of the skin (G, H). Nymph burrowing just below the skin surface to moult into an adult in 3–4 days (I). Side-axial view of an adult female specimen of S. scabiei in a tunnel in the superficial epidermis. The mites have a short and broad gnathosoma (gn), globose idiosoma, short and conical legs I and II, with a delicate chitinous coating (le). Structures associated with the female reproductive system, spermatheca (sp), ovarian nutrient cell (ONC) located inside the ovary (ov), vitellogenic oocyte (oc) in the oviduct (ovd), as well as chorional gland (chg) close to oviporus (op) are visible (J).
