“…This scenario is complicated because in this genus there are several genotypes (G1-G10), that vary in their biology, rate of development, pathogenicity, and geographical extent, and some of which are now considered as new different species. So, all genotypes causing CE are denominated as E. granulosus sensu lato , whereas genotypes G1-G3 are denominated E. granulosus sensu strictu 40–42 . As the most frequent human infections are due to genotypes G1-G3, and specially G1, the cases analyzed in this study likely correspond to E. granulosus sensu strictu .…”

Human parasitic infections are major contributors to global disease load, compromising the human life and resulting in considerable morbidity and mortality worldwide. However, many parasitic diseases have been neglected and little investigated in western medicine. Although recently developed molecular techniques have revolutionized the taxonomy of parasites and the parasitic disease diagnosis, histopathology still remains a powerfull tool for the analysis of parasitic diseases, allowing direct observation of the parasite thus providing information about the morphological features of the parasite ifself, and revealing tissue alterations at the parasite-host interface. The recently developed RGB trichrome (acronym for the primary dye components, picrosirius Red, fast Green, and alcian Blue) stains the main components of the extracellular matrix, specifically collagens and proteoglycans. We have applied the RGB tricrome staining to human tissues infected by the main three classes of human parasites: Protozoa (Leishmania donovanii and Toxoplasma gondii), helminths (Trichinella spiralis, Enterobius vermicularis, Dirofilaria spp. and Echinococcus granulosus) and ectoparasites (Demodex folliculorum and Demodex brevis). Trichrome stain results in detailed staining of the parasite microanatomical structure, and highlights host tissue alterations such as granulomatous inflammation, immune cell infiltrate, or increased amount of collagen as a sign of parasite-induced fibrosis. Yet, the use of RGB trichrome, as a complement of hematoxylin and eosin staining, provides additional valuable information to assess parasitic infection histopathology.

“…En este sentido, entre los factores sociales se puede mencionar el cambio en una dieta esencialmente basada en granos a otras con altos contenidos de proteína animal. En cuanto a los aspectos sanitarios se puede mencionar la globalización de los mercados que muchas veces permite la internacionalización de las enfermedades, y la ausencia de amalgamación de los sistemas de vigilancia y monitoreo epidemiológico humano-veterinario, algo de vital importancia en el caso de las ETAs en donde muchos de los organismos causales corresponden a zoonosis y otros menos, son antropozoonosis (García et al, 2020).…”

“…Finalmente, la acción antrópica sobre los ecosistemas y el cambio climático, pueden generar condiciones como la eutrofización, que permiten el crecimiento de algunos organismos. Si los metabolitos de estos organismos pueden ser permeados en las distintas cadenas tróficas y ser humano, se constituye un problema palpable para los consumidores (García et al, 2020).…”

“…De esta forma, el enfoque UnaSalud, se convierte en una estrategia necesaria para hacer frente a la lucha contra las ETAs. Su aplicación correcta permite la transdisciplinariedad, el monitoreo sindrómico de los microorganismos y otros tipos de agentes de interés en materia de salud pública, así como también; la generación de bases de datos necesarias para la toma de decisiones en un sistema agroalimentario cada vez más complejo en donde la acción de la gestión sanitaria debe incluir un compromiso entre el sector estatal y productivo (Lee, 2017;García et al, 2020).…”

Introducción: Las Enfermedades de Transmisión Alimentaria (conocidas comúnmente con el acrónimo de ETAs), impactan significativamente en los sistemas de salud de los países. Objetivo: Realizar una búsqueda temática que identifica los principales peligros de tipo biológico causantes de ETAs descritos en Costa Rica, y relacionar los principales alimentos de origen animal con los cuales se vinculan. Metodología: Realizamos una búsqueda de información científica bajo la modalidad de revisión literaria de cohorte narrativo y descriptivo, desde junio de 2015 hasta diciembre de 2020. Seleccionamos para la presente revisión bibliográfica, únicamente artículos con descripción de uno o varios organismos patógenos que estuvieran vinculados con matrices alimentarias de origen animal, en el territorio costarricense. Resultados: Identificamos 27 tipos de organismos biológicos asociados con cuadros de ETAs, aislados de distintas matrices de origen animal en Costa Rica. Conclusión: Existe una pluralidad de organismos frecuentemente asociados con infecciones, toxoinfecciones e infestaciones en el ser humano. Con un panorama creciente de incremento en el consumo de productos de origen animal para hacer frente al crecimiento poblacional al año 2050, estos retos se incrementan en paralelo. Para ello es imperativo la implementación del concepto UnaSalud en los esquemas productivos de los países.

Background Cholangiohydatidosis (CH) is an evolutionary complication of hepatic cystic echinococcosis, associated with increased morbidity and mortality. The aim of this study was to describe the available evidence regarding clinical characteristics of CH, postoperative complications and hospital mortality. Methodology/Principal findings Systematic review. Studies related to CH with no language or publication restriction were included. Sensitive searches were performed in Trip Database, SciELO, BIREME-BVS, WoS, PubMed, EMBASE and SCOPUS. MeSH and free terms were used, including articles up to April 2023. The main outcome variables were postoperative complications and hospital mortality; the secondary ones were publication year, origin and design of primary studies, main clinical manifestation, anatomical location and type of cysts, hospital stay, surgical procedure performed, reinterventions; and methodological quality of primary studies, which was assessed using MInCir-T and MInCir-P scales. Descriptive statistics, calculation of weighted averages and their comparison by least squares logistic regression were applied. 446 studies were retrieved from the searches performed, 102 of which met the inclusion and exclusion criteria. The studies analyzed represent 1241 patients. The highest proportion of articles was published in the last decade (39.2%). Reports are mainly from Turkey (28.4%), Greece (9.8%), Morocco and Spain (8.8% each). With a weighted mean of 14.3 days of hospital stance; it was verified that 26.2% of patients developed postoperative complications (74,3% Clavien y Dindo III y IV), 6.7% needed re-interventions, and 3.7% died. When comparing the variables age, postoperative complications, hospital mortality, and reinterventions in two periods of time (1982–2006 vs. 2007–2023), no statistically significant differences were found. When applying the MInCir-T and MInCir-P scales, the methodological quality of the primary studies was 9.6±1.1 and 14.5±4.3 points, respectively. Conclusion/Significance CH is associated with severe postoperative complications and significant hospital mortality, independent of the development of therapeutic support associated with the passage of time.
