Current Status and Perspectives of Cysticercosis and Taeniasis in Japan

Abstract

This mini-review describes recent epidemiological trends in cysticercosis and taeniasis in Japan. Some of the topics discussed herein were presented at the first symposium on "Current perspectives of Taenia asiatica researches", that was held in Osong in Chungbuk Province, South Korea, in October 2011 and organized by Prof. K. S. Eom, Chungbuk National University School of Medicine. To better understand the trends in the occurrence of cysticercosis and taeniasis in Japan, clinical cases reported in 2005 have been updated. In addition, the current status of Taenia asiatica infections successively occurring in Japan since 2010 is also discussed.

Disseminated Cysticercosis along with Multiple Ring Lesion in MRI: Case Report

“…However we described a case of multiple ring lesion cysticercosis with dissemination to parotid gland and orbit. Yamasaki (2013) while studying epidemiology of cysticercosis in Japanreported51.9% of patients having multiple lesions.…”

Epidemiology ofDiphyllobothrium nihonkaienseDiphyllobothriasis, Japan, 2001–2016

“…Regarding Spirometra plerocercoids, 2 species ( S. erinaceieuropaei and S. decipiens ) have been found to be responsible for human sparganosis in Japan ( 21 ). However, these 2 species were not identified by DNA analysis in this study.…”

“…( 39 ). In contrast, human taeniasis has been exclusively reported as imported cases, but T. asiatica infections in Japan have been confirmed to be autochthonous infections through the consumption of raw pork liver ( 17 , 40 ). …”

Priorities for research and control of cestode zoonoses in Asia

“…Some participants reported the situation of taeniasis and cysticercosis in humans and livestock in Asian countries, including an infection survey which surprisingly showed that T. asiatica was reported in 25 confirmed patients in Japan and linked to the consumption of raw pig liver. However the origins of the taeniasis cluster could not be identified due to a lack of geographical variations in the DNA markers used [31]. …”
