Detection of Genetic Variation in Taenia solium
Journal of Parasitology, 2003Genetic variability among Taenia solium isolates was studied in 160 cysticerci from 6 pigs, 4 from Mexico, 1 from Honduras, and 1 from Tanzania. Random amplified polymorphic DNA (RAPD) analysis performed with 4 commercial primers showed 88% polymorphic loci and an average heterozygosity of 0.077; however, several alleles were fixed within each isolate.

Taenia solium: Immunity in hogs to the cysticercus
Experimental Parasitology, 1983Protection was induced in hogs against Taenia solium cysticercosis using an immunogenic complex obtained from its larval "bladder worm" form, Cysticercus cellulosae. Immunoelectrophoresis revealed that this complex contained at least eight antigens. In immunized hogs a total of 71 (mean 11.8) cysticerci were found, whereas in the control animals 397 ...

Differentiation of Taenia saginata and Taenia solium by enzyme electrophoresis
Transactions of the Royal Society of Tropical Medicine and Hygiene, 1977Forty-four Taenia saginata and seven T. solium specimens were collected in Nigeria. Extracts of these worms and of their metacestodes were compared by enzyme electrophoresis. The mobility of glucose phosphate isomerase was consistently faster with T. saginata than with T. solium. Extracts of the strobilate and cysticercus forms of the same species gave

Immunopathology in Taenia solium neurocysticercosis
Parasite Immunology, 2016SummaryNeurocysticercosis is a clinically and radiologically heterogeneous disease, ranging from asymptomatic infection to a severe, potentially fatal clinical picture. The intensity and extension of the parasite‐elicited inflammatory reaction is a key factor for such variability.

Porphyrin Content of the Cysticercus of Taenia solium
The Journal of Parasitology, 1986The strong red fluorescence of the cysticercus of Taenia solium depends on the presence of several porphyrins in the vesicular fluid of the parasite: probably protoporphyrin IX, coproporphyin I or III, and 2 decarboxylated porphyrins intermediate between uroporphyrin and coproporphyrin. Cyst porphyrins associated to form conglomerates of high molecular

Fractionation and characterisation of the cysticercus of Taenia solium
Research in Veterinary Science, 1987Fractionation by chromatography on Sephadex G-200 of a saline extract of Cysticercus cellulosae scolex antigen yielded three distinct fractions associated with distinct peaks. These fractions were analysed by double immunodiffusion (DID) and immunoelectrophoresis (IEP).

Elimination ofTaenia soliumTransmission in Peru
New England Journal of Medicine, 2016Garcia et al. (June 16 issue) conclude that the transmission of taeniasis and cysticercosis was interrupted in a region in which these diseases are endemic owing to mass drug administration in humans and pigs. We are not convinced that this costly strategy provides a long-term solution for eradicating taeniasis and cysticercosis.

Characterization of Glutathione S-Transferase of Taenia solium
The Journal of Parasitology, 1999A Taenia solium glutathione-S-transferase fraction (SGSTF) was isolated from a metacestode crude extract by affinity chromatography on reduced glutathione (GSH)-sepharose. The purified fraction displayed a specific glutathione S-transferase (GST) activity of 2.8 micromol/min/mg and glutathione peroxidase selenium-independent activity of 0.22 micromol ...

Gene structure of Taenia solium paramyosin
Parasitology Research, 2003Paramyosin is a muscle protein that probably plays a role in the survival of the larval stage of Taenia solium during its prolonged host-parasite relationship. Here we describe the structure of the gene coding for the paramyosin of T. solium. The characterization of two clones obtained from a genomic library showed that the complete gene of paramyosin ...

Morphological types of Taenia solium cysticerci
Parasitology Today, 1989In human brain cysticercosis, there are three morphological types of cysticercus. Teresa Robielo, Angelica Rivas and Ana Flisser describe the appearance and possible taxonomic position of these forms, and discuss their relation to the various pathologies of neurocysticercosis.
