Strongyloidiasis is a parasitic disease, caused by a nematode helminth, Strongyloides stercoralis. The true prevalence of S. stercoralis is likely underestimated because infection is often subclinical. Currently, an estimated 100 million people are infected worldwide in more than 70 countries (Concha et al., 2005 -. Segarra et al., 2007). Though many advances have been made in the diagnosis and...

BACKGROUND An enzyme-linked immunosorbent assay (ELISA) and indirect immunofluorescence assay (IFA) were evaluated for serological diagnosis of human strongyloidiasis. METHODS Serum specimens obtained from 46 individuals infected with Strongyloides stercoralis, 37 healthy persons and 381 persons with other parasitic infections were tested using an IgG-ELISA that used crude antigen of S. sterc...

Strongyloides stercoralis, usually infects only the mucosa of the small intestine. Hyper-infection by S. stercoralis, however, is a serious complication and is characterised by invasive filariform larvae that produce lesions in the liver, lungs, colon, stomach and other organs. Individuals with intestinal strongyloidiasis are often asymptomatic but may have abdominal pain, weight loss, diarrhoe...

conclusion the identification of immunodominant proteins adapted to the physiological and genetic conditions of the host is an appropriate diagnostic approach, which could be associated with improved sensitivity and specificity of serologic tests. results four immunodominant proteins (23, 28, 30, 41 kda) were recognized with strongyloidiasis sera in 0.1 diluted serum. none of the proteins react...

Autoinfective strongyloidiasis is often fatal in immunosuppressed patients or in immunocomprised hosts. An interesting case of Strongyloides stercolaris hyperinfection was seen in an immunocompetent patient. This report describes a case of fatal strogyloidiasis in a 79 year old man, who had suffered gastrointestinal discomfort for years, and who presented because of respiratory illness. A chest...

A 61-year-old diabetic man had fever and a significant exudative type of eosinophilic pleural effusion. Microscopic examination of stained specimens of bronchial washings revealed filariform larvae of Strongyloides stercoralis. This intestinal nematode is endemic in some areas of the world. Pulmonary symptoms are usually mild, though severe pulmonary involvement may be occasionally seen. Althou...

Strongyloidiasis affects 30 million people in 70 countries. This enteral parasitosis is usually diagnosed using parasitological tests based on hydrotropism or thermotropism of larvae eliminated in feces, but these tests have been shown to have low sensitivity. In this study, antigenic extracts were tested by means of ELISA, immunoblotting and IFI, using filariform larvae of Strongyloides venezu...

We report an atypical occurrence of invasive Strongyloides stercoralis infection of the stomach mucosa in an elderly female patient from Bangka Island, northwestern Indonesia. The patient presented with severe epigastric pain, edema of the legs, proteinuria and severe hypoalbuminemia. Gastric and duodenal biopsies found eggs, larval and adult forms present in the superficial mucosa with mild in...
