Występowanie niektórych pasożytów jelitowych w przebiegu cyklu życiowego człowieka. I. Celowość badań hematologicznych przy diagnozowaniu owsicy u ludzi

Studies were carried out to show the usefulness of haematological examinations for helminthological diagnosis in deteetion nf oxyuriasis in patients of different age. Long-term examinations were carried out at the analytical laboratory of the Mining Centre of Curative and Professional Rehabilitation at Repty Śląskie, involying 4,404 persons aged 4-84. Oxyuriasis was found to occur in people of different age, though with different intensity. The highest extensivness was found in children up to ten yeaTs of age (13.53%) and in adults over sixty (8.95%). Eosinophilia in peripheral blo0d was found in only three from among 233 patients infected. This would suggest that examinations in the aspect of eosinophilia for detection of oxyuriasis do not meet the purpose.
