hook worm (necator americanus) is one of the major pathogenic parasites in the north of iran. neonatal hamsters 1-3 days old showed a high degree of susceptibility to necator americanus infection and the parasite reached to sexually mature stages in six weeks following skin exposure. this method could be used for production of egg, larvae and adult worms. in this study neonatal hamsters were in...

More sensitive diagnostic methods for detecting worms’ eggs are needed in areas with low soil-transmitted helminth (STH) prevalence. The Harada-Mori technique was first introduced by Mr. Harada and Mori. This is easy, simple, does not require sophisticated equipment. based on larvae tropism nature the water to concentrate of hookworms Strongyloides stercoralis. Since its application 1955, this ...

An agar plate (AP) method has been developed for culturing infectious larvae of the hookworm Ancylostoma ceylanicum. The third-stage larvae reared using the AP method displayed similar morphology to those cultured using Baermann or Harada-Mori coproculture techniques. The yield of viable larvae from the AP method (50%) was comparable to that of the Baermann (47%), and both were superior to Hara...

Introduction: It is estimated that 100 - 300 million people in the world are infected with Strongyloides stercoralis. Although there are several laboratory diagnostic methods for detection of this parasite, there is still no gold standard diagnostic method. The need for an application test with high sensitivity and specificity is highly felt, especially in people with immune deficiency or organ...

Strongyloides stercoralis is a soil-transmitted helminth infecting humans that can cause hyperinfection and disseminated disease in the immunocompromised host. This case report describes 56-year-old patient, diagnosed with hepatic metastasis, who was screened for strongyloidiasis by faecal culture. The agar plate culture became positive on third day of incubation, demonstrating characteristic t...

A survey on intestinal parasitic infections and some risk factors of infection (social, economic and behavioral) was conducted in suburban area at Simum subdistrict, Mueang district, Nakhon Ratchasima Province during the period of April 3rd to April 11th, 2007. A total of 214 stool samples, from 85 males and 129 females were examined using simple direct smear, Kato’s thick smear and modified Ha...

Human immunodeficiency virus (HIV) and intestinal parasites are common in Brazil. Previous studies have shown that infection with Strongyloides stercoralis is frequently associated with HIV infection. Strongyloidiasis is difficult to diagnosis and stool examination with conventional techniques fails to detect the helminth larvae. We made a prospective study, to test the efficacy of the agar pla...

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...
