A serological survey was performed using ELISA to estimate the prevalence of tissue and luminal helminthic infections among hospital patients in Hanoi region, Vietnam. An overall seroprevalence of tissue and luminal helminthiases was 64.0% (95% CI 61.2-66.8) among 1,120 patients who visited Hanoi Medical University Hospital, Vietnam in 2018. The highest seroprevalence was observed against Toxocara spp. (59.0%), followed by Strongyloides stercoralis (46.3%), Gnathostoma spp. (25.5%), cysticercus (12.8%), Angiostrongylus cantonensis (10.5%), Fasciola spp. (11.1%), and Clonorchis sinensis (8.7%). Mono-infection by one species (11.1%) was lower than multiple infections (53.0%) (P<0.05). The seroprevalence in males (59.3%) was lower than in females (66.2%) but not statistically significant (P>0.05). Children (<15 years) revealed lower seroprevalence (34.0%) than adults (68.4%), and the age group 51-70 years revealed the highest seroprevalence (76.0%). Among the seropositive patients, eosinophilia (≥8.0%) was noted in 80.2%. The present results suggested active transmission of various tissue and luminal helminths among people in Hanoi, Vietnam.

Brief Communication

Molecular Identification of Taenia hydatigena from Sheep in Khartoum, Sudan: Rosline James Muku, Hong-Bin Yan, John Asekhaen Ohiolei, Abubakar Ahmed Saaid, Sara Ahmed, Wan-Zhong Jia, Bao-Quan Fu; Korean J Parasitol 2020;58(1):93-97.
Published online February 29, 2020; DOI: https://doi.org/10.3347/kjp.2020.58.1.93

The cestode Taenia hydatigena uses canids, primarily dogs, as definitive hosts, while the metacestode larval stage cysticercus infects a range of intermediate hosts, including domestic animals such as goats, sheep, and pigs. Cysticercosis due to T. hydatigena has large veterinary and economic drawbacks. Like other taeniids, e.g., Echinococcus, intraspecific variation is found among the members of the genus Taenia. In Africa, few studies are available on the epidemiology and distribution of T. hydatigena, and even fewer studies are available on its genetic variation. In this study, we molecularly identified 11 cysticerci from sheep in Sudan and demonstrated the genetic variation based on the NADH dehydrogenase subunit 1 (nad1) and cytochrome c oxidase subunit 1 (cox1) mitochondrial genes. The isolates were correctly identified as T. hydatigena with more than 99% similarity to those in the GenBank database. Low diversity indices and insignificant neutrality indices were observed, with 3 and 2 haplotypes for the nad1 and cox1 genes, respectively. The results suggest the presence of unique T. hydatigena haplotypes in Sudan, as haplotypes with 100% similarity were not found in the GenBank database. With few available studies on the genetic variation of T. hydatigena in Africa, this report represents the first insights into the genetic variation of T. hydatigena in Sudan and constitutes useful data.

Case Report

Clinical and Pathological Characteristics of Intraocular Cysticercosis: Juan-Juan Li, Li-Wei Zhang, Hua Li, Zhu-Lin Hu; Korean J Parasitol 2013;51(2):223-229.
Published online April 25, 2013; DOI: https://doi.org/10.3347/kjp.2013.51.2.223

Abstract
PDF

This study aimed to explore the clinical, radiological, and pathological characteristics of intraocular cysticercosis due to Taenia solium metacestode infection. Total 8 patients diagnosed with intraocular cysticercosis at the Red Cross Hospital of Yunnan Province, China were examined retrospectively. Patients with clear dioptic media had undergone fundus chromophotography. All patients underwent B ultrasonography of the ocular region (CT) successive scanning of the orbit and cerebral tissues. Parasites were extracted surgically and then examined pathologically. The fundus chromophotography showed a white and condensing scolex package in the vesicle. The B ultrasonic examination showed a vesicle-like echogenic mass in the vitreous chamber, in which the high-level echo spot was the cysticercus scolex. The pathological examinations showed that the vesicle wall exhibited hyaline degeneration, inflammatory cell infiltration, neuroglial fiber, and glial cell proliferation layers from the inside to the outside. The scolex is round and is composed of the outer tissue (the body wall) and the inner furrow tissue; these tissues migrated together. Primordially differentiated sucking discs were found in one case, but no hooklets were found. The inner scolex tissue was folded like a paper flower. The severity of intraocular disease is closely correlated with the pathophysiological processes of the cysticercus worm. Pathological examination of the intraocular lesions can help to evaluate the course of the disease as well as to provide a scientific basis for effective antiparasitic medication.
