Quite a few of my clients have come to the States from foreign countries, and others send me their work directly from overseas.  I have by now had a good deal of experience in helping these authors with their particular problems.

Strongyloides stercoralis is a nematode that most often found in areas where the moist & warm climate conditions are available , since it provide with the appropriate circumstances for living & breeding ^(2,5). Strongyloides has the ability replicating itself both in the soil & within the human body and uniquely has the characteristic of autoinfection which explain the prolong period of infection that may reach 30 years or more.

Stool microscopic examination still one of important diagnostic tools for S. stercoralis but keep in mind that negative examination do not rule out the diagnosis, because of the intermittent spillage of the larvae in the stool. The diagnostic yield of a single stool examination is 30%, that could enhanced up to 60% when five samples or more are examined. To overcome this obstacle, the duodenal aspirate microscopic examination is more reliable with a diagnostic yield can reach 90% ^(1,2,4,14).

     Microscopic stool examination remains one of the most important diagnostic tools with this parasite, but it must be borne in mind that a negative examination does not rule out the diagnosis, since appearance of the larvae in the stool is intermittent.  The diagnostic yield of a single examination is 30%, which can be increased to 60% with five samples.  Microscopic examination of duodenal aspirate can reach a yield of 90%. ^1,2,4,14
