morphological description of taenia saginata asiatica (cyclophyllidea: taeniidae) from man in asia.	in order to clarify the taxonomic status of the taenia saginata-like tapeworm in east asia, the morphological characteristics of the adult and cysticercus of classical t. saginata (american, swiss and poland strains) and the taiwan taenia were compared in the present study. the morphologic characteristics of these two parasites are very similar. the protoscolex of cysticercus of the taiwan taenia has a sunken rostellum while that of classical t. saginata has only an apical pit. in addition, the ...	1995	8583124
ectopic locations of taenia saginata asiatica cysticerci in the abdominal cavity of domestic pig and monkey.	eleven small-ear-miniature pigs, 1 landrace small-ear-miniature pig, and 1 monkey (macaca cyclopis) were infected experimentally with eggs of taenia saginata asiatica. they were found to harbor cysticerci on the liver surface, each with a thin, whitish fiber connecting to another location in the same lobe, or to other lobes of the liver; some were also connected individually to the diaphragm, abdominal muscles, and gall bladder with a short, thin fiber. moreover, they also harbored extrahepatic ...	1996	8973419
annual economic loss caused by taenia saginata asiatica taeniasis in three endemic areas of east asia.	the taenia saginata-like tapeworm in east asia has been designed as a separate subspecies of t. saginata. it was named as t. saginata asiatica and the classical t. saginata as t. saginata saginata. in the course of conducting experimental infections and morphological studies, a large number of adult worms of t. saginata asiatica was collected. it is possible to estimate the annual economic loss caused by this infection, since the worm load and the weight of worm habored by each infected person w ...	1997	9656381
review of taeniasis in asia.	although asian taenia is closely related to t. saginata, it is a genetically distinct entity and can be distinguished from the classical t. saginata. man is the only definite host of this parasite. the domestic pig and wild boar in taiwan as well as domestic pig in korea have been determined to be the natural intermediate hosts. moreover, the pig has been demonstrated to be the most favorable experimental intermediate host. the cysticerci are situated mainly in the liver. they are smaller than t ...	1995	9774987
human taenia in severe combined immunodeficiency (scid) mice.	a rodent model for the development of the larval stages of human taeniid tapeworms would help advance immunodiagnosis in human and domestic animals and vaccine development for cysticercosis cellulosae or bovis in domestic animals. here, akira ito and mamoru ito review recent results demonstrating the potential of the severe combined immunodeficiency (scid) mouse for supporting development of the larval stages of taenia saginata asiatica, t. saginata and t. solium.	1999	10234188
oncospheres of taenia solium and t. saginata asiatica develop into metacestodes in normal and immunosuppressed mice.	normal and immunosuppressed mice were infected with oncospheres of taenia saginata asiatica and t. solium. although normal icr mice were not susceptible to these two parasites, cysticerci were recovered from the immunosuppressed ones following venous injection. for t. s. asiatica, immunosuppressed icr mice had an infection rate of 12.5% and six cysticerci of this parasite were recovered from three males. after injection of t. solium oncospheres, a high infection rate of 57% was obtained and 23 c ...	1999	10431380
taenia saginata asiatica: epidemiology, infection, immunological and molecular studies.	the taeniasis in east asia has a special epidemiological pattern: people eat meat and/or viscera of pigs and acquire infection of taenia saginata-like tapeworms. however, cysticercosis is more often found in pigs than cattles. in order to elucidate the taxonomic status of this parasite, we have conducted extensive field surveys, experimental infections, and morphological as well as immunological studies since 1981. after obtaining sufficient information from our studies, we finally came to the c ...	1998	10596984

differential diagnosis of taenia saginata and taenia saginata asiatica taeniasis through pcr.	new multiplex-pcr and pcr-linked restriction fragment length polymorphism protocols, derived from taenia saginata hdp2 dna sequence, have been designed that allow the simultaneous and specific identification of t. saginata and taenia saginata asiatica. proglottids expelled from 20 different spanish taeniasis patients, previously diagnosed as t. saginata by both morphological identification and multiplex hdp2-pcr, were also examined by the newly developed pcr protocols, and the original diagnosis ...	2004	15246508
annual economic loss caused by taenia saginata asiatica taeniasis in east asia.	taeniasis is an important medical and economic problem in many countries in east asia, especially in the mountainous and remote areas where the inhabitants are fond of eating raw or undercooked meat. p.c. fan here discusses how sociocultural factors and local customs can contribute to the transmission of taeniasis and evaluates the economic losses caused by the disease.	1997	15275091
development of taenia saginata asiatica metacestodes in scid mice and its infectivity in human and alternative definitive hosts.	development of taenia saginata asiatica metacestodes in scid mice, and its infectivity in humans, golden hamsters, and mongolian gerbils as alternative definitive hosts, were investigated. cysticerci were recovered from scid mice that were subcutaneously injected with hatched oncospheres of t. s. asiatica. the morphological changes of metacestodes were observed. the recovered cysticerci were fed to gerbils, hamsters and humans, to check for their infectivity. tapeworms were recovered from gerbil ...	2005	15812671
acute pancreatitis caused by tapeworm in the biliary tract.	taeniasis is a helminthic infection endemic in southeast asia, including taiwan. recent studies suggest that asian taenia is a new subspecies of taenia saginata and has been renamed as taenia saginata asiatica. it is usually asymptomatic or associated with only mild gastrointestinal symptoms. we report the case of a 52-year-old woman with acute epigastric pain and vomiting. her levels of amylase and lipase were significantly elevated on admission. gastrointestinal endoscopy showed proglottids of ...	2005	16103608
pig as a favorable animal for taenia saginata asiatica infection.	the epidemiology of taenia saginata in some parts of asia is confusing, in that beef does not appear to be the source of infection. in some areas, beef is either not available or not eaten raw, whereas pork at times is eaten uncooked. in light of this situation, we have exposed pigs and other animals to infection with strains of t. saginata to establish their ability to serve as intermediate hosts. eggs of taiwan taenia, korea taenia, indonesia taenia, thailand taenia, philippines taenia, ethiop ...	2006	16570562
human tapeworms in north vietnam.	sixty-five taenia samples were collected from patients in a referral hospital in hanoi, north vietnam, for species identification by morphological and molecular techniques. pcr-rflp of a mitochondrial 12s rdna fragment, developed for this study, allowed direct differentiation between all taenia spp., overcoming the disadvantages of classical morphological examination, which failed on disintegrated samples. taenia saginata asiatica was the most common species (55.4%) followed by t. saginata (38.5 ...	2007	16806333
isolation of a 14 kda antigen from taenia solium cyst fluid by hplc and its evaluation in enzyme linked immunosorbent assay for diagnosis of porcine cysticercosis.	a fraction with a major band of 14kda was obtained from crude cyst fluid of taenia solium cysticerci by 2-step chromatography. a first fraction isolated by gel filtration (sephacryl s-300 high resolution) was purified using an anion exchange column (mono q hr 5/5) on high performance liquid chromatography. evaluation of the analytic sensitivity of this fraction (f3) was carried out in an antibody enzyme linked immunosorbent assay (ab-elisa-f3) using serum samples from pigs experimentally infecte ...	2007	17101161
