  1. Epidemiological study of Taenia solium taeniasis/cysticercosis in a rural village in Yucatan state, Mexico.

    Article - En anglais

    A survey to detect human taeniasis and cysticercosis was conducted in a community in Yucatan state, Mexico, an area endemic for Taenia solium.

    Information on the environmental, demographic and risk factors associated with transmission of T. solium within the community was recorded on questionnaires.

    Although no Tacnia eggs or proglottides were found in the initial faecal samples collected from each of the 475 subjects, the results of a capture-ELISA for T. solium coproantigen were positive for 10 of the subjects (of both genders and various ages).

    After treatment with niclosamide, proglottides were detected in purge samples from seven of these 10 subjects.

    The prevalence of parasitologically confirmed taeniasis was therefore 1.5% (seven in 475).

    The other three ELISA-positive cases delayed supplying faccal material post-treatment, and it is unclear whether they had expelled proglottides before providing the samples.

    All 10 ELISA-positive subjects became ELISA-negative after treatment.

    Seroprevalence of human cysticercosis, based on the detection in immunoblots of antibodies to antigens of 8-and 26-kDa from a crude saline extract of T. solium metacestodes, was 3.7% (i.e. five positives out of 134 subjects).

    None of the seropositive cases demonstrated clinical symptoms of infection.

    Again, the positive cases were of both genders and various ages.

    Although tongue palpation indicated that 17 (23%) of 75 pigs kept within the community had T. (...)
