Because strongyloidiasis could theoretically be transmittable through unsanitary bedclothes care must be taken never to use unclean hotel bed sheets in endemic areas. In the direct development, first-stage larvae (L1) transform into infective larvae (IL) via three molts. An S. stercoralis infection can cause the following complications: Eosinophilic pneumonia occurs when your lungs swell due to an increase in eosinophils. Diagnosis: skin scrapings, skin biopsy, impression smear and cytology. Strongyloidiasis Treatment Treatment for strongyloidiasis is recommended for all persons found to be infected, whether symptomatic or not, due to the risk of developing hyperinfection syndrome and/or disseminated strongyloidiasis. Sarcoptes scabiei var canis infestation is a highly contagious disease of dogs found worldwide. Images /. The medicine of choice to treat strongyloidiasis is a single dose of the antiparasitic medication ivermectin (Stromectol). During the parasitic phase, infected rodents can transfer worm populations to other rodent colonies [2, 14]. To date, occurrence of autoinfection in humans with helminthic infections is recognized only in Strongyloides stercoralis and Capillaria philippinensis infections. Ivermectin is the drug of choice for treatment, due to its low side effect profile. Sarcoptes scabiei var canis infestation is a highly contagious disease of dogs found worldwide.
