RESUMO
INTRODUCCIÓN: Anisakis spp., durante la parasitación, libera antígenos de excreción secreción (ES) que, al ponerse en contacto con el sistema inmunológico del hombre, pueden desencadenar una respuesta de hipersensibilidad mediada por la IgE, provocando diversos síntomas alérgicos. OBJETIVOS: Evaluar la respuesta de la IgE en ratas Wistar tras la infección con larvas L3 del parásito. MÉTODOS: Se ha procedido a la obtención de antígenos ES del parásito y suero anti-Anisakis. Se investigan también en este trabajo ciertos factores que intervienen en la técnica de inmunotransferencia, como la concentración de poliacrilamida empleada en la preparación de los geles, la concentración antigénica utilizada y la temperatura requerida para la desnaturalización de las proteínas. RESULTADOS: Las reacciones inmunológicas (Ag-Ac) observadas mediante esta técnica muestran mayor intensidad con los sueros obtenidos después de la reinfección, los cuales han reconocido proteínas que podrían corresponder al antígeno principal Ani s 1 y a otros polipéptidos de interés en el diagnóstico de la anisakiosis humana. CONCLUSIÓN: En este trabajo, se pone de manifiesto que inmunotransferenciala inmunotransferencia es una técnica útil para detectar anticuerpos de tipo IgE frente a proteínas de Anisakis
INTRODUCTION: Anisakis spp., during parasitism, release excretory-secretory antigens that, in contact with the human immune system, can trigger a hypersensitivity response mediated by IgE, causing various allergic symptoms. OBJECTIVES: To evaluate the IgE response in Wistar rats after infection with L3 larvae of the parasite Anisakis spp. METHODS: Some determining factors involved in the technique have been improved in this work, such as: the concentration of polyacrylamide used in the preparation of the gels, the antigen concentration used, and the temperature required for denaturation of proteins. RESULTS: Immune responses (Ag-Ab) observed by the immunoblotting technique showed a greater intensity with serum obtained after reinfection, which have recognized proteins that may correspond to the major antigen Ani s 1 and other polypeptides of interest in the diagnosis of human anisakiasis. CONCLUSION: This paper concludes that immunoblotting is a useful technique to detect IgE antibodies against Anisakis proteins

Objetivos: Estudiar la posible actividad sinérgica de los aceites esenciales de Mentha piperita y Matricaria chamomilla frente Anisakis tipo I. Material y métodos: Se ensayó tanto in vitro como in vivo, la actividad larvicida de la mezcla de los aceites esenciales utilizando albendazol como fármaco de referencia y midiéndo su eficacia mediante un modelo estadístico. Resultados: En los ensayos in vitro, a las concentraciones de 250 y 187.5 μg/ml, la mortalidad de las larvas fue del 100% mientras que albendazol no mostró eficacia. In vivo, la mezcla de aceites esenciales fue más eficaz, reduciendo las lesiones en ratas en comparación con las tratadas con albendazol y control. Albendazol no redujo de forma significativa el porcentaje de lesiones producidas por las larvas frente al control. Conclusión: La mezcla de aceite esencial de menta y manzanilla podría ser candidata para su uso en el tratamiento/profilaxis de la anisakiasis humana
Aim: We have studied the possible synergistic activity of the essential oils of Mentha piperita and Matricaria chamomile against Anisakis type I. Materials and methods: the larvicidal activity of the mixture of essential oils was tested in vitro and in vivo, using as a reference the drug Albendazole and effectiveness measured through a statistical model. Results: The in vitro and in vivo experiments both evidenced that the larvicidal activity of essential oils, was higher than the Albendazole activity. In the in vitro assay, at concentrations of 250 and 187.5 μg/ml, the mortality was 100% with the mixture of essential oils while albendazole was ineffective at the concentrations studied. In the in vivo assay, the mixture of essential oils, was significantly more effective in the reduction of numbers of lesions with rats in comparison to albendazole treatments and control. Albendazole did not significantly reduce the percentage of lesions caused by larvae vs. control. Conclusion: Considering the results, we have come to the conclusion that the mixture of peppermint essential oils and chamomile could be used in the treatment/prophylaxis of human Anisakis
