The first case of bertiellosis in China-morphology of the proglottids and the epidemiologic significance of the case

Objective: To explore the identification of the proglottids of Bertiella studeri for providing evidences for the pathogenic diagnosis of human bertiellosis.Methods: The segments were collected from the patient's feces and observed directly' and then fixed with 10% formaline,the morphology data of the proglottids were measured,recorded and analyzed.Results: The segment collected in the patient's feces contained several to more than dozens proglotiids,the average length of the proglottids was 0.1 cm and width 0.68-1.10 cm.The living segment could contract strongly and formed a special biangular end.Conclusions: The shape of the segment collected from the patient's feces could changed remarkably by means of contraction and the morphologic characteristics of the proglottids that the width is far more than its length,both the characteristics and the epidemic data are important clue for bertiellosis diagnosis.
