Q

Pathogenesis and Clinical Manifestations

  • Enterobiasis or Oxyuriasis

Relatively innocuous parasite and rarely produce serious problems

  • Mild inflammation of the intestinal mucosa and secondary bacterial infection may occur due to attachment of worms to the walls

Migration of the egg-laying females to the anus causes irritation of perineal region - itching and scratching - secondary bacterial infection
