Sparganosis is a parasitic infestation caused by the larval stage of Spirometra erinacei. Human infection results from ingestion of raw or undercooked flesh of any of the numerous intermediate hosts and from application of such flesh as poultices. Sparganosis have been reported from orbit and bulbar conjunctiva. But, urogenital infestation of Sparganum is rarely observed. We report an additional case of the sparganum infestation in the right scrotum.

Sparganosis is an infection caused by the migrating larvae of the cestode genus Spirometra. The most common clinical presentation of a sparganosis is a slow-growing, sometimes migratory, sub-cutaneous mass. In this report, a case of eosinophilic panniculitis by sparganum in a Korean woman is presented. The diagnosis was confirmed from the histopathologic findings, the micro-ELISA tests and a living sparganum derived from the patient while excising the new lesion

Sparganosis is a parasite infestation caused by the larval stage of Spirometra erinacei. Ingestion of raw or undercooked flesh of numerous intermediate hosts results in human infection. Sparganum infestation of human body was reported over 120 cases including urogenital lesions in Korean literatures since 1924. But, no case of sparganosis in the spermatic cord was reported until now. We experienced a case of sparganosis in the spermatic cord.

Human sparganosis in Korea was discussed on the bases of five human cases experienced by the present authors and 58 case records already reported by many previous authors, in aspects of epidemiology and clinical features. Sparganosis is not infrequent tissue helminthiasis now in Korea and the incidence has been evidently increased during past 10 years. It might be interpreted that improved medical delivery system and health care exposed the hidden but prevalent disease. The distribution of sparganosis in Korea is apparently subdivided into three major endemic areas; Kyunggi Do, Kyungsang Do and Hamkyung Nam Do. Although scanty in other areas of Korea, the distribution of this disease is presumably throughout the whole peninsula of Korea except Cheju Do. The majority of human cases of sparganosis in Korea has revealed raw consuming of snakes for treatment of tuberculosis, syphilis and joint pain, for tonics and for the belief of special nutrition among very limited group of Korean population. Because of this kinds of mode of infection, comprising four fifths of all cases, the majority of cases detected were male adult consisting of about 70% of total cases. And drinking of untreated water in rural area where no protective, sanitary measures for water sources were provided in the past, seems another important causes of infection especially in women and children in Korea. Thus it may be concluded that sparganosis in Korea is concluded by eating of infective stages per os voluntarily or involuntarily, but not through the direct invasion. Clinically, subcutaneous mass or lump was the most frequent problem in those patients and those masses were associated with inflammatory signs. By the anatomical location of the lesion, some peculiar manifestations could be developed as in orbital, abdominal, urethral, ureteral and vertebral cases. And the lesions could be complicated by haemorrhage or abscess formations. The larval worms hitherto collected in Korea has been identified tentatively as Sparganum mansoni because neither branched larvae nor Sparganum proliferum were ever reported.

Distribution of Sparganum mansoni in 7 species of terrestrial snakes in Wonju City was surveyed. All kinds of snakes were found to be served as intermediate hosts of this larval worm except Elaphe schrenkii which has already been recorded as important host. Authors believe that Zamenis spinalis was firstly recorded as intermediate host of Sparganum mansoni in Korea. Some aspects of infection status, host-parasite relations and sources of human infection were briefly discussed.

To observed whether the specific IgG antibody test using ELISA was useful in diagnosis of presently ill patients of paragonimiasis, a total of 95 sera were tested. The sera were collected from 21 egg positive cases, 8 from positive reactors of intradermal test, 7 from Clonorchis infected, 9 from other parasitic diseases and 50 from apparently non-infected cases. By the result, the sensitivity of the test was 86% and the specificity was 100%. There were no cross reactions between Paragonimus antigen and other parastic infections. Specific IgG antibody test by micro-ELISA was concluded to be useful for mass screening of the presently ill paragonimiasis in the field.

Spargana were collected from human and frogs in Liaoning and Hubei Provinces, China. PCR amplification and direct sequencing of A cox1 fragment was PCR-amplified from genomic DNA extracted from 7 specimens (5 from humans and 2 from frogs). The cox1 fragment (390 bp) showed 97–100% similarity to the reference sequence of S. erinaceieuropaei and 88–89% to the reference sequence of S. decipiens. There were 1–12 bases different between these worms, but no obvious genetic variation (0–3.3%) to the references. There was little difference of cox1 gene between sparganum samples of humans and frogs (1–3%). This study is the first report on S. erinaceieuropaei spargana from humans in Liaoning and Hubei Provinces.

Sparganosis is an infection caused by sparganum, the generic term for the migrating plerocercoid larva of tapeworm which belongs to the species Spirometra. We experienced two cases of sparganosis. The first patient was a 49-year-old woman. She visited our hospital because of a painful subcutaneous nodule on her left forearm, which had developed on her left shoulder at first and migrated to the medial aspect of the forearm. She had drunk fresh water 12 years ago at a mountain. The second patient was a 39-year-old man who showed a subcutaneous nodule on the right lower leg. He had eaten raw snake about 20 years ago. Sparganosis was confirmed after the larval worms were found in the excised tissues in both cases.

Prevalence of sparganum in the frog (Rana nigromaculata) was surveyed in Dae-jeon city and in suburbs of the city, Chungnam Do. 39 (3.9 per cent) out of 1,011 frogs were infected with the worm, and the highest prevalence rate of sparganum was found the frogs from Shintanjin area(11.3 per cent). Infection rates of sparganum were observed due to the body weight and sex of frogs. The highest infection rate of frogs, the body weight of 50 gms or more, showed 30.3 per cent(female: 41.7 per cent, male: none), on the other hand, no worm was found in young frogs(less than 10 gms). Distribution of sparganum in the frogs was recorded and 82.6 per cent of worms were distributed in the femoral intermuscular connective tissues of the hind legs. Among those infected frogs, number of worm burden was one to five worms, and 53.3 per cent of frogs were infected by only one worm.

We studied the serological reaction between various antigenic components from Cysticercus cellulosae and IgG antibodies in sera of cysticercosis, sparganosis, hydatidosis patients and normal humans by ELISA and EITB. In serological tests by ELISA, we recognized cross reaction of Cysticercus antigenic components with IgG antibodies in heterologous sera such as sparganosis and hydatidosis patients or normal humans. The crude antigenic components of Cysticercus showed lower ELISA sensitivity in homologous sera from cysticercosis patients than heterologous sera from hydatidosis patients. A total of 31 polypeptide bands with 260 KDa-22 KDa molecular weights were detected by SDS-PAGE, and 11 of them showed strong intensity. Total 22 components of them were recognized by IgG antibodies in cysticercosis patients sera. However, 12 of them were recognized also by normal human sera, 11 were by sparganosis sera, and 21 were by hydatidosis patients sera. The crude antigenic components of 104 KDa, 82 KDa, 72 KDa, 59 KDa and 34 KDa molecular weights were nonspecific ones, which cross-reacted with sera of either cysticercosis, sparganosis, hydatidosis patients or normal humans.
