title: [Value of the string test in the diagnosis of duodenal parasitosis].
abstract: Diagnosis of small intestine parasitosis can be realized by string-test. This examination, easily performed, does not produce side-effects in ninety percent of cases. The main problems are: good string unrollment and duodenal passing over. When Necator ova or gardia cysts are found in the stools by the Junod's technic, string-test is always positive. In one case, this latter even showed Schistosoma mansoni ova. Among 18 patients with unexplained hypereosinophilia, in spite of a parasitologic check up involving three stools examinations, the string-test showed Necator ova. With regard to strongyloidiasis, when properly performed, string-test is positive in seventy percent of cases. Therefore, this technic seems very useful on the field or in laboratories which do not usually realize the Junod's technic.
