Abstract Background Intramedullary parasitic infection is extremely uncommon, and clinical presentation of Brown-Sequard syndrome is even rarer. Case presentation The authors report a case involving a 57-year-old woman with Brown-Sequard syndrome, in whom magnetic resonance imaging and clinical and epidemiological features were similar to those of acute transverse myelitis. Myelotomy suggested inflammation caused by latent parasite eggs in the spinal cord. Antiparasitic and steroid therapies were administered postoperatively. To the author’s knowledge, this is the first report to describe a surgical experience for Taenia solium eggs in the spinal cord. Conclusion Intramedullary parasitic infection is a diagnostic challenge that requires careful discrimination from other diseases. If parasite infection is suspected in a progressively deteriorating patient, myelotomy should be considered for rapid and accurate treatment.

La fase larvaria del parásito Taenia solium puede enquistarse en el sistema nervioso central causando neurocisticercosis, que es la principal causa de epilepsia adquirida en los países donde el parásito es endémico. Las zonas endémicas son aquellas con presencia (o probable presencia) del ciclo vital completo de T. solium. El parásito es más prevalente en comunidades pobres y vulnerables donde los cerdos deambulan libremente, las personas defecan al aire libre, el saneamiento básico es deficiente y la educación para la salud es inexistente o insuficiente. Hay varias herramientas disponibles para el control de Taenia solium. Una de ellas es la quimioterapia preventiva para la teniasis por Taenia solium, que se dirige a la tenia adulta. Otras herramientas se centran en el manejo de los cerdos, su vacunación y tratamiento, el saneamiento y la higiene, y la educación de la comunidad. Se ha considerado el uso de tres fármacos —niclosamida, prazicuantel y albendazol— para la quimioterapia preventiva en los programas de control de la teniasis por Taenia solium mediante la administración masiva de medicamentos o la quimioterapia dirigida. En estas directrices, ofrecemos recomendaciones para la quimioterapia preventiva en zonas donde la infestación por Taenia solium es endémica, mediante el uso de niclosamida, prazicuantel o albendazol, incluida la dosis que se debe usar y los grupos de población destinatarios. La elaboración de estas directrices se basa en los últimos estándares más recientes de la Organización Mundial de la Salud para la elaboración de directrices, incluido el uso de estrategias de búsqueda sistemática, la síntesis, la evaluación de la calidad de la evidencia disponible para apoyar las recomendaciones, y la participación de expertos y partes interesadas en el Grupo de Elaboración de las Directrices y el Grupo de Examen Externo. Las recomendaciones se dirigen a un público amplio, como responsables de la formulación de políticas y sus asesores expertos, así como el personal técnico y de programas de las instituciones y organizaciones gubernamentales que participan en la planificación, la implementación, el seguimiento y la evaluación de los programas de QP para el control de T. solium.

Contextualization: The antiparasitic resistance caused by the indiscriminate use of anthelmintic drugs for the control of gastrointestinal parasites in production animals and pets, has become one of the biggest problems in animal health. For this reason, the use of vaccines could benefit animal health and welfare by controlling emerging zoonotic diseases and foodborne pathogens of animal origin, thus improving public health. Knowledge gap: It is relevant for professionals in veterinary science to know the clinical trials of experimental vaccines for controlling certain gastrointestinal parasites.   This way, they can be at the forefront of the next available technological products and so, be able to control this menace to the animal health and public health.  Purpose: To do a systematic review of clinical trials for experimental vaccines in production animals and pets for diseases caused by gastrointestinal parasites of relevance in animal production and/or public health. Furthermore, it presents the current gastrointestinal antiparasitic vaccines commercialized in different countries and their prophylactic efficacy. Methodology: PRISMA protocols were followed for this systematic review. Articles were obtained from scientific databases with the following keywords: vaccines, clinical trials, commercial vaccines, parasites control, gastrointestinal nematodes, gastrointestinal cestodes, gastrointestinal protozoa, Ascaris suum, Ancylostoma caninum, Cooperia oncophora, Echinococcus granulosus, Eimeria spp., Giardia lamblia, Haemonchus contortus, Osteortagia osteortagi, Taenia solium and Teladorsagia circumcincta.  Only clinical trials of gastrointestinal antiparasitic vaccines in birds, pets, pigs and ruminants were included in this analysis, as well as commercial vaccines currently available for these same parasites.  Results and conclusions: Even though there are important clinical trial studies of vaccines in these animal species (n=101) reported between 1964 to 2020, only five parasites can be prevented/controlled with commercial vaccines used in veterinary medicine: Haemonchus contortus and Echinococcus granulosus in ruminants, Taenia solium in pigs, Eimeria spp. in birds and Giardia lamblia in dogs (e.g., Cysvax™, Barbervax®, Providean® Hidatil EG95, CocciVac® and GiardiaVax™). It is expected that, with the development of bioinformatics and methodologies such as reverse vaccinology, this immunoprophylactic and immunotherapeutic range will be extended as to control these parasitic agents of great importance in human and animal health.

Introducción: La neurocisticercosis (NCC) es una zoonosis parasitaria del sistema nervioso central causada por el céstodo Taenia solium, y que afecta a países en desarrollo y con escaso saneamiento básico. Objetivo: Describir el uso y la concordancia de la imagen radiológica por tomografía (TAC) o resonancia magnética (RM) y serología por western Blot (WB) en el diagnóstico de la NCC en un hospital del norte del Perú. Material y Métodos: Estudio observacional retrospectivo. La historia clínica fue la unidad de análisis. Los casos se buscaron en la oficina de Epidemiología mediante el CIE-10- B69 y registro del Laboratorio de Parasitología, Metaxénicas y Zoonosis del mismo hospital, en el periodo del año 2015 al 2017. Resultados: Se estudiaron 67 historias clínicas, que cumplían con los criterios diagnósticos absolutos de NCC. Los pacientes fueron varones en el 55,2 % y tuvieron una media de edad de 40,2 (±17,8) años. El 35,9% tuvieron un resultado positivo por WB (19/39), las lesiones quísticas con escólex fueron observada en el 25,4% de las TAC y en el 29,6 de las RM. La concordancia observada entre la prueba serológica con TAC y RM fue escasa, siendo (Kappa=0,073, IC95%: 0,053 – 1,084) y (Kappa=0,112, IC95%: 0,092 – 1,092) y un porcentaje de acuerdo de 42,0% y 45,7% respectivamente. Conclusiones: Se observó uso diferenciado y escasa concordancia entre la prueba serológica por WB e imagen radiológica en pacientes con diagnóstico de neurocisticercosis en la población estudiada.

Combined community health programs aiming at health education, preventive anti-parasitic chemotherapy, and vaccination of pigs have proven their potential to regionally reduce and even eliminate Taenia solium infections that are associated with a high risk of neurological disease through ingestion of T. solium eggs. Yet it remains challenging to target T. solium endemic regions precisely or to make exact diagnoses in individual patients. One major reason is that the widely available stool microscopy may identify Taenia ssp. eggs in stool samples as such, but fails to distinguish between invasive (T. solium) and less invasive Taenia (T. saginata, T. asiatica, and T. hydatigena) species. The identification of Taenia ssp. eggs in routine stool samples often prompts a time-consuming and frequently unsuccessful epidemiologic workup in remote villages far away from a diagnostic laboratory. Here we present “mail order” single egg RNA-sequencing, a new method allowing the identification of the exact Taenia ssp. based on a few eggs found in routine diagnostic stool samples. We provide first T. solium transcriptome data, which show extremely high mitochondrial DNA (mtDNA) transcript counts that can be used for subspecies classification. “Mail order” RNA-sequencing can be administered by health personnel equipped with basic laboratory tools such as a microscope, a Bunsen burner, and access to an international post office for shipment of samples to a next generation sequencing facility. Our suggested workflow combines traditional stool microscopy, RNA-extraction from single Taenia eggs with mitochondrial RNA-sequencing, followed by bioinformatic processing with a basic laptop computer. The workflow could help to better target preventive healthcare measures and improve diagnostic specificity in individual patients based on incidental findings of Taenia ssp. eggs in diagnostic laboratories with limited resources.

The urgency of the problem of human teniases is due to the widespread prevalence of these parasitoses, which often infect humans.The aim and result of the work is to summarize the available information about the etiology, epidemiology, pathogenesis, clinical picture, diagnosis, etiotropic therapy and prevention of human teniases.Conclusion. Teniases are widespread, including on the territory of Russia. The clinic mainly includes symptoms of lesions of the gastrointestinal tract, allergic reactions. Diagnostics is carried out on the basis of the detection of eggs, proglottids, coproangigens of parasites in the feces, serological and molecular genetic tests. Praziquantel is an effective etiotropic therapy. Prevention takes into account the peculiarities of the epidemiology of teniases.
