Cestode infections in Korea.

Epidemiological surveys concerning cestodes of medical importance in Korea have been sporadically reported by many workers. Among various parasitic infections, cestode infections occur less frequently than other helminthiases, but they often cause serious clinical complications. Cestodes reported so far in Korea belong to the Order Pseudophyllidea or Cyclophyllidea (Subclass Cestoda), i.e., Diphyllobothrium latum, D. yonagoense, Spirometra erinacei, sparganum, Hymenolepis diminuta, H. nana, Mesocestoides lineatus, Taenia saginata, T. solium, metacestode of T. solium (cysticercus), and Echinococcus granulosus. The present paper is a brief review of the literature concerning these cestode infections in Korea. Taeniases by T. saginata or T. solium are prevalent cestode infections in Korea, and cysticercosis by T. solium often reveals serious clinical manifestations. H. nana infection is relatively rare, showing 0.22% egg positive rate in a nationwide survey in 1986. Sparganosis by the plerocercoid larva of Spirometra is not an uncommon cestode infection in man, and 16 kinds of animal hosts including the snakes and frogs have been reported. D. latum infection has been an uncommon intestinal parasitosis, but it tends to increase nowadays. Most of human hydatidosis cases have been recognized as imported ones from outside Korea, but one case was proven indigenous. Other 4 kinds of cestodiases are extremely rare in Korea and only a few cases have been recorded.

Cestode infections in animals: immunological diagnosis and vaccination.

Cestode infections in animals are important because several species are zoonotic, causing cysticercosis and hydatidosis in man, and because of the economic losses incurred due to infections in livestock. Information on immunological diagnosis of and vaccination against cestode infection is restricted almost exclusively to the taeniid cestodes in which two groups of mammalian hosts are concerned: the intermediate host infected with the larval parasite and the definitive host infected with the adult tapeworm parasite. Research towards developing serological tests for the diagnosis of larval cestode infection in animals has been largely unsuccessful. Substantial problems remain, due to the frequent existence of multiple infections with different taeniid species and antigenic crossreactivity between these related parasites, and the low level of specific antibody response to infection. Problems with poor specificity and sensitivity of traditional serological tests for cysticercosis and hydatidosis have prevented the development of any practical test for ante-mortem diagnosis of infection. A recent new approach to the diagnosis of Taenia saginata infection by detecting circulating parasite antigen offers some prospect for the development of a practical diagnostic test for cysticercosis in cattle. The effectiveness of the arecoline purge for detection of Echinococcus granulosus in dogs has been reduced by the widespread availability of praziquantel. A serological method for diagnosis of E. granulosus in dogs has been developed which offers equivalent or superior diagnostic sensitivity compared with arecoline purge. This test should provide a valuable tool in hydatid control campaigns for the diagnosis of existing or recent past infections in dogs. Substantial progress has been made towards developing a practical vaccine for the prevention of T. ovis infection in sheep. An antigen derived from the parasite egg has been identified and produced in Escherichia coli using recombinant DNA techniques. The vaccine, which protects sheep against challenge infection with T. ovis, is the first highly effective defined antigen vaccine against any parasite infection of man or animals. Commercial development of this vaccine is in progress. The success achieved with the T. ovis vaccine augurs well for the rapid development of other recombinant vaccines against cysticercosis caused by other taeniid species and against hydatidosis in animals.

[Cestode infections in 1997].

In 1997, 736 intestinal cestode cases were registered in Poland. Among them 634 were caused by T. saginata, 6 by T. solium, 63 by Taenia sp, 15 by Hymenolepsis sp, and 2 by D. latum and D. caninum. Moreover, 27 cases of larval cestode infections were also registered. Four of them were caused by larvae of T. solium and the remaining ones bz E. granulosus. The obtained results confirmed the decreasing frequency of infections with intestinal cestodes in Poland.

Moreover, 31 cases of larval cestode infections were also registered. Three of them were caused by larvae of T. solium and the remaining ones by E. granulosus. The obtained results confirmed the decreasing frequency of infections with intestinal cestodes in Poland.

Hybridoma antibody immunoassays for the detection of parasitic infection: attempts to produce an immunodiagnostic reagent for a larval taeniid cestode infection.

Attempts have been made to produce discriminatory immunodiagnostic reagents for infections of sheep with the larval stages of Taenia hydatigena, Taenia ovis and Echinococcus granulosus. Using cells from mice hyperimmunized with T. hydatigena antigenic preparations for fusion, a hybridoma antibody which bound to T. hydatigena larval antigens, but not to T. ovis or E. granulosus larval antigens, was selected. A competitive radioimmunoassay using the labelled hybridoma antibody and a crude parasite antigen mixture was devised as an immunodiagnostic test for experimental T. hydatigena infection. Sera from sheep exposed to 1000 or more T. hydatigena eggs were unequivocally positive but sera from 2 sheep with a monospecific infection with T. ovis were also positive. Sera from E. granulosus-infected sheep were negative and, although the numbers of sera involved were small, such discrimination has not been achieved by previous serologic methods. The discussion emphasizes various difficulties which have been encountered in the development of highly sensitive as well as specific hybridoma-based immunodiagnostic reagents for the detection of larval cestode infections in sheep.

Field evaluation of the efficacy and safety of emodepside/praziquantel spot-on solution against naturally acquired nematode and cestode infections in domestic cats.

Two controlled, blinded and randomized multi-site clinical field studies evaluated the efficacy and safety of emodepside/praziquantel spot-on in the treatment of gastrointestinal nematode and cestode infections in cats. In a study conducted in Europe, faecal egg count reductions of >98% for all nematode eggs and eggs of Toxocara cati, respectively, were observed in cats treated with emodepside/praziquantel spot-on (Profender, Bayer AG, Leverkusen, Germany). For a positive-control product containing selamectin (Stronghold) reductions of >95% were observed. A 100% reduction of faecal eggs and proglottids was observed in cats treated with emodepside/praziquantel spot-on that were infected with cestodes. In a study conducted in North America, cats were treated with either emodepside/praziquantel spot-on plus a placebo tablet or a combination of two control products containing, respectively, selamectin (Revolution) and epsiprantel (Cestex). Faecal egg count reduction for eggs of T. cati was >99% for both treatments. For faecal eggs and proglottids of Dipylidium caninum reductions of >99 and >97% were recorded for cats treated with emodepside/praziquantel spot-on and the control group, respectively. No adverse reactions were observed in the European study, and only mild ones of short duration in a few cats from both treatment groups of the North American study. The two studies demonstrated that emodepside/praziquantel spot-on is highly efficacious and safe under field conditions.
