RESUMO
La teniasis es una parasitosis intestinal causada por la forma adulta de los cestodos (gusanos planos). En el ser humano se presentan dos especies, Taenia solium y Taenia saginata, ambas hermafroditas y que requieren un huésped intermediario para cumplir su ciclo: ganado porcino y ganado bovino respectivamente. El hombre es el huésped definitivo en el cual se desarrolla la forma adulta. La clínica principal de Taenia saginata es digestiva, mientras que Taenia solium puede afectar a otros tejidos. Se presenta el caso de una adolescente que elimina parásitos en la ropa interior y heces sin otro síntoma. Los describen como gusanos blancos, planos y móviles. En la anamnesis refiere que le gustan los chuletones de carne poco cocinada, pero sin concretar un posible foco de la infestación. Se realiza un análisis con resultado normal, excepto una eosinofilia de 9,6%. En el laboratorio de Microbiología, por visión directa tras tinción con tinta china y reacción en cadena de la polimerasa directa se confirma el diagnóstico de Taenia saginata. Tras el resultado, se le indica tratamiento con prazicuantel vía oral en dosis única (medicamento off-label), sin presentar efectos secundarios (AU)
Taeniasis is an intestinal parasitic infection due to an adult worm of tapeworms (cestodes). In humans, there are two main species: Taenia solium and Taenia saginata, both of them are hermaphrodites and require an intermediate host to complete their life circle: beef tapeworm (Taenia saginata) and pork tapeworm (Taenia solium). Humans are the only definitive host in which the adult form develops. Taenia saginata manly causes gastrointestinal symptoms, while Taenia solium can affect other tissues. We report the case of a teenager who found a number of adult worms on her intimate clothes and in her stools without any other symptom. The worms were described as flat, white and mobile. At the review, she said that she loved eating undercooked meat, without determining the source of the infection. We detected high eosinophilia level in blood test (9,6%). A microbiological test identified proglottids in the stool with a direct examination, and polymerase chain reaction methods established a species diagnosis of Taenia saginata. As a result, we started treatment with prazicuantel orally single dose (off-label) without presenting any side effects (AU)

The ovicidal activity of the nematophagous fungi Pochonia chlamydosporia (isolates VC1 and VC4), Duddingtonia flagrans (isolate AC001) and Monacrosporium thaumasium (isolate NF34) on Taenia saginata eggs was evaluated under laboratory conditions. T. saginata eggs were plated on 2% water-agar with fungal isolates and controls without fungus and examined after 5, 10 and 15 days. At the end of the experiment P. chlamydosporia showed ovicidal activity against T. saginata eggs (p<0.05), mainly for internal egg colonization with results of 12.8% (VC1) and 2.2% (VC4); 18.1% (VC1) and 7.0% (VC4); 9.76% (VC1) and 8.0% (VC4) at 5, 10 and 15 days, respectively. The other fungi showed only lytic effect without morphological damage to the eggshell. Results demonstrated that P. chlamydosporia was effective in vitro against T. saginata eggs unlike the other fungi.

Com o objetivo de demonstrar a eficácia do fungo Paecilomyces lilacinus sobre ovos de Taenia saginata em condições laboratoriais, foi montado ensaio em placas de Petri com agar - água 2 por cento. Houve atividade ovicida (p<0,05) em relação ao grupo controle no décimo dia de interação e colonização interna dos ovos de 25,5 por cento.
With the aim of demonstrating the effectiveness of the fungus Paecilomyces lilacinus on Taenia saginata eggs under laboratory conditions, a trial was set up in Petri dishes with water-agar 2 percent. There was ovicidal activity (p < 0.05) in relation to the control group on the tenth day of interaction and an internal colonization rate of 25.5 percent in the eggs.
