Juvenile and adult specimens of the branchiuran crustacean parasite, Argulus foliaceus , have been found to exhibit the brown areas of damaged cuticle typical of crustacean shell disease. Transmission and scanning electron microscopy of such lesions at a variety of sites on the body surface have demonstrated that they harbour dense populations of bacteria and occasionally fungi, in zones of superficial cuticular erosion. Complete penetration of the exoskeleton was inferred in instances when circular lesions were associated with bacteraemia of underlying soft tissues.
