In order to describe bovine neosporosis as a livestock health problem in the Andes, the determinants, epidemiology and control of this parasitosis were identified, for this purpose a review of the literature published in the ScienceDirect collection was made, finding that the canine is the main determinant for bovine neosporosis, as a propagator in the stable of the protozoan Neospora caninum, other factors are related to the components of the production system and cattle breeds; It was observed that horizontal transmission of bovine neosporosis occurs through dog excreta contaminating cattle feed and vertical transmission occurs in young cows with low immunity, thus affecting their offspring, with fetuses being infected by N. caninum, causing abortions or reproductive problems such as return to estrus or temporary loss of estrus, a situation that causes important economic losses for cat...

The workshop “Parasitic Zoonoses in the Context and Approach of One Health” was held within the framework of the International Congress of Neotropical Parasitology in 2024, an event that brought together multiple specialized symposia dedicated to the region’s health challenges. The purpose of the workshop was to strengthen the comprehensive understanding of parasitic zoonoses from the “One Health” paradigm, which recognizes the interdependence among human, animal, and environmental health as a single, dynamic, and deeply interconnected system. This article aims to disseminate an integrative disciplinary experience developed by the academic community under the One Health approach to parasitic zoonoses. The participation of specialists from Peru, Mexico, Colombia, Uruguay, and Brazil enriched the regional perspective and enabled the discussion of parasitological issues from diver...

La investigación realizada, tiene como objetivos evaluar como las biopelículas en el sistema de distribución de agua potable influyen en la calidad de agua que consume la población del barrio de Calvario de la ciudad de Moyobamba, determinar la presencia de biopelículas en el sistema de distribución de agua potable, caracterizar los parámetros físicos, químicos y microbiológicos del agua que consumen y determinar a que riesgos sanitarios por consumo de agua potable está expuesta la población del barrio de Calvario de la ciudad de Moyobamba. Se analizaron 4 muestras de agua, 2 en redes de distribución y 2 en conexiones domiciliarias teniendo en cuenta que la formación de biopelículas en las tuberías de agua post tratamiento de potabilización, es debido al tiempo de antigüedad y al tipo de material que es utilizado, como el PVC, presión de llegada del agua e infiltracion...

Toxocariasis, a zoonotic parasitic infection primarily caused by Toxocara canis and T. cati, remains a neglected yet widespread public health issue in Latin America. This comprehensive review explores its biological, clinical, epidemiological, and socio-economic dimensions, emphasizing the disease’s underrecognition in endemic areas. Transmission occurs through accidental ingestion of embryonated eggs from contaminated environments, particularly affecting children in low-income settings. In humans, larvae migrate aberrantly, causing visceral, ocular, and neurological syndromes with substantial morbidity. The burden is compounded by limited diagnostic infrastructure, inconsistent access to antiparasitic therapy, and inadequate veterinary and environmental controls. High seroprevalence and environmental contamination rates are reported across Latin America, yet toxocariasis is absent fro...

Mr. Editor We have read with special attention and interest the article by Condemayta et al (2018), where they present the results of an epidemiological study on the prevalence of infection by the intestinal parasite "Balantidium coli" and the risk factors associated with its transmission. in humans and pigs in two populations of the Acora District, province and Department of Puno, Peru. In general, we agree with the content of the article. However, we wish to comment on the taxonomic and systematic status of "Balantidium coli", and the corresponding nomenclature of the enteroparasitic disease it causes, which we consider require updating in light of the new evidence and findings presented in the scientific literature of the area, especially those of the molecular type. In this sense, it should first be indicated that the genus Balantidium belongs to the Phylum Ciliophora (Class Litostom...

Plasmodium falciparum en la Amazonía de Perú se ha descrito en años recientes como una población clonal, presentándose en casos de infecciones monoclonales, y que los parásitos que actualmente circulan serían producto de un reemplazo clonal. Adicionalmente, la frecuencia de los parásitos portadores de la deleción de los genes pfhrp2 y pfhrp3 ha aumentado, predominando en la población de P. falciparum. Por otro lado, no se conoce que factores genéticos podrían subyacer a la persistencia de las infecciones por P. falciparum y al incremento en el tiempo de los parásitos con la deleción de los genes pfhrp2/3. Por ello, el objetivo principal del presente estudio fue identificar regiones genómicas de P. falciparum que muestren evidencia de selección positiva reciente para esta especie; y de manera específica, en el grupo de parásitos con la deleción de los genes pfhrp2 y pfh...

El objetivo de este estudio fue identificar el conocimiento y prácticas de riesgo de infección de Fasciolosis en la población del distrito de Pampachiri, Andahuaylas - Apurímac. Para ello se diseñó un estudio transversal descriptivo a base de encuestas por viviendas, que incluyó información demográfica, características de crianza de animales, prácticas de riesgo en personas y conocimientos sobre la enfermedad. Se obtuvieron 296 encuestas válidas de personas entre 18 y 65 años de edad, entre septiembre y octubre del 2024. La encuesta fue aplicada de manera presencial utilizando un cuestionario impreso. La población cría a sus animales principalmente en un sistema de pastoreo a campo abierto (66.8%), con pastos naturales (61.3%) y con agua obtenida de ríos y acequias (54%). El 15.9% de los pobladores no contaban con el servicio de agua potable y 86.5% de desagüe. El 48.6% ...

Introducction: neurocysticercosis is the most common parasitic disease of the Central Nervous System in Perú; it is hyperendemic in the Highlands and also in some areas of the Coast and Jungle.Objectives: To determine the prevalence and risk factors related to neurocysticercosis in workers of a slaughterhouse in an impoverished area of Lima.Materials and methods: this is a transversal study in 60 workers of a slaughterhouse in the capital of Perú; the workers underwent a clinical, epidemiological and serological (EITB) evaluation; an axial computer tomography was obtained from those who were EITB positive. The O.H Del Brutto (1996) neurocysticercosis diagnostic criteria were used. The prevalence of neurocysticercosis and its association with risk factors were calculated with the SPSS statistical package, v 10.0.Results: the prevalence of neurocysticercosis in our st...

Introduction: Toxocariasis is an infection caused in canines, felines, humans, and other vertebrates by species of the genus Toxocara, such as T. canis and T. cati. The embryonated eggs of these parasites are the main form of acquisition of the infection both for definitive hosts, such as the dog and the cat, respectively and for paratenic hosts, such as humans and other vertebrates. Toxocariasis infection in humans causes visceral larva migrans syndrome. When deposited on park soils, environmental contamination becomes a risk for environmental, human, and animal health. Objective: To systemically estimate the prevalence of Toxocara spp. eggs in park soils in Latin America. Methods: A systematic review and meta-analysis were performed to evaluate the prevalence of Toxocara eggs in park soils in Latin America, defined by copro-parasitological, molecular and immunological techniques. We se...
