Strongyloides stercoralis.

In many aspects, S stercoralis is a unique opportunistic pathogen. Via its autoinfections cycle, it is capable of producing both parasitic and bacterial infections at remote organ sites. These infections are often nosocomial. Diagnosis can be very difficult if appropriate microscopic evaluation is not done. Concomitant bacterial infections must be treated with appropriate antimicrobial agents; thiobendazole is the treatment of choice for the parasitic phase of these infections.
