Background Strongyloides stercoralis causes chronic intestinal infection that may lead to disseminated disease during immunosuppression. Therefore, efficient diagnostic methods are essential to detect silent and latent infections. The present study was aimed to compare the efficacy of parasitological methods for the detection of S. stercoralis infection. Methods A cross-sectional study was co...

The course of infection and immunological responses in dogs infected with a strain of Strongyloides stercoralis of human origin were investigated. The first dog infected developed a chronic infection lasting at least 15 months. Larvae disappeared from the faeces by three months after infection in another four dogs; these animals were resistant to challenge infection. A further dog developed a c...

The present study was performed to reveal the current status and risk factors of Strongyloides stercoralis infections in the villages of Kenethao district, Xayaburi Province, Lao PDR. Fecal specimens were collected and examined for S. stercoralis using Koga-agar plate culture technique. Among 516 individuals, the prevalence of S. stercoralis and hookworm infection was 44.2% and 17.1%, respectiv...

Critical investigations into the cellular and molecular biology of parasitic nematodes have been hindered by a lack of modern molecular genetic techniques for these organisms. One such technique is transgenesis. To our knowledge, the findings reported here demonstrate the first heritable DNA transformation and transgene expression in the intestinal parasite Strongyloides stercoralis. When micro...

Although developmental timing of gene expression is used to infer potential gene function, studies have yet to correlate this information between species. We analyzed 10,921 ESTs in 3311 clusters from first- and infective third-stage larva (L1, L3i) of the parasitic nematode Strongyloides stercoralis and compared the results to Caenorhabditis elegans, a species that has an L3i-like dauer stage....

BACKGROUND Strongyloidiasis is mostly an asymptomatic infection and diagnosis of latent infections is difficult due to limitations of current parasitological and serological methods. This study was conducted to set up a PCR-based method for molecular diagnosis of Strongyloides stercoralis infection by detection of copro-DNA in stool samples. METHODS A total of 782 fresh stool samples were col...
