Background Strongyloides stercoralis is a soil-transmitted helminth that penetrates the skin as a method of infection. This parasitic worm gains nutrients and shelter from its host, while causing malnourishment or harm to the diseased. The infective filariform penetrates the skin from infected soil and migrates to the lungs through the blood stream. In order to mature the filariform larvae are coughed up and swallowed to develop into adults in the intestines. The diagnostic stage is the rhabditiform first stage larvae in feces.…
