Antigen extracts obtained from the vesicular fluid of Taenia crassiceps cysticerci and from fractions purified by affinity chromatography with the lectin concanavalin A and the glycoprotein antigen separated by electrophoresis were used for the detection of Taenia solium anticysticercus antibodies. The sensitivity and specificity obtained for all antigens were 100% in enzyme-linked immunosorben...

La carta al editor se refiere al artículo de Canaval-Zuleta et al. aceptado para publicación, titulado "Endoscopy as an alternative diagnostic and therapeutic technique for Taenia saginata". El trabajo presenta una serie de incorrecciones que deben ser aclaradas, o al menos parte de ellas en solo 300 palabras. La información sobre las vias de infeccion en taeniasis, así como la patogenia y técn...

Maitotoxin (MTX), the most potent known marine toxin, isolated from toxic dinoflagellates and poisonous fish, caused a dose-dependent contraction of the guinea-pig isolated ileum and taenia caeci at concentrations of 100 pg to 30 ng/ml. These contractile responses to MTX (3 ng/ml) in both tissues were abolished by incubation in Ca2+-free solution and were markedly inhibited by treatment with me...

Mexican and Colombian Taenia solium cysticerci and some species of Taenia adults were assayed using cellulose acetate electrophoresis to distinguish between isolates. Isozyme patterns for ARK, GOT, G3PD, GPI, and MPI were identical in all cysticerci suggesting homozygotic profiles. G6PD and MDH showed different patterns between Mexican and Colombian cysticerci, suggesting regional differences. ...

Taenia saginata (T. saginata) is one of the most common cestode in human. We report a case of intestinal perforation caused due to T. saginata infection. The patient, 54-year-old female, had intermittent abdominal pain, diarrhea and vomiting on referral. Intestinal obstruction and perforation leading to necrosis, and volvulus due to an impacted tapeworm was observed. Histopathological examinati...

Previous studies have shown that Ca influx increased but Ca efflux did not change during the contracture of taenia coli induced in hypertonically added 40 mm potassium solution (1) and the results were supported by the others (2-6). Further, the movements of Ca in the muscle in high-K solution might be differently affected by ouabain and 2, 4-dinitrophenol during the abolition of the tonic tens...

The effects of external divalent cations on drug-receptor interaction were examined using guinea pig taenia. The effects of histamine on membrane potential of taenia in various solutions were also examined using the sucrose gap method. Ca2+ and Me2+ played an important role in the combination of histamine with its receptor. Sr2+, Mn2+ and Co2+ do not substitute for. Ca2+ and Me2+ in this intera...
