Helminths are a group of invertebrates of major scientific interest due to their high impact on public health and the diverse evolutionary histories that some of its members have followed in order to adapt to the parasitic lifestyle. In the Neotropical region, though, helminth research has been traditionally associated with their effect on public health. This topic awaits more reflection and political support for its beneficial implementation, especially in rural zones where the prevalence of infection by helminth parasites in humans can be very high (Cabrera, 2003).

Soil contaminated with helminth parasites of animals can pose risks of zoonoses to humans. It is important to determine the transmission dynamics of embryonated eggs of Toxocara canis (Werner, 1782). The aim of this study was to evaluate soil contamination by T. canis eggs in public parks in the district of Santiago de Surco, Lima, Peru in 2007 and 2008. The study was descriptive, longitudinal and comparative. Soil samples were evaluated in November-2007 (spring, n = 39), June-2008 (autumn, n = 37) and November-2008 (spring, n = 41); a total of 117 samples of soil (n = 84) and grass (n = 33) from 51 public parks representing the district of Santiago de Surco, Lima, Peru. At each site we measured the area of the park, collecting between 1 to 1.5 kg of soil sample into five equidistant points (four laterals and one central) at a depth of 5 cm. The samples were stored at room temperature fo...

Spotted Butterfish Stromateus stellatus (Cuvier, 1829) is a pelagic species that lives on the continental shelf where it forms small schools. Its geographic distribution includes mainly Ecuador, Peru and Chile, and further south in South America. Eighty specimens of S. stellatus were obtained from the coastal zone of Chorrillos, Lima, Peru between December, 2008 and September, 2009 to assess the community ecology of parasitic fauna. Of the tested fish, 51 were females and 29 were males. The fish showed a mean total length of 16.5 ± 1.8 cm (12 cm to 22.5 cm). Metazoan parasites were collected and plotted using standard parasitological procedures. The parasite assemblage presented a higher percentage of internal parasites (97.2%) compared to ectoparasites. The mean parasite species richness was 0.4 ± 0.6 (0.0 to 3.0). Fifty-four hosts (67.5%) were infected and 26 hosts (32.5%) were infec...

Two mite species of the genus Neharpyrhynchus (Acariformes: Harpirhynchidae) were recorded on wild birds in Peru: Neharpyrhynchus trochilinus from Amazilia lacteal, and A. chionogaster (both Apodiformes: Trochilidae) and Neharpyrhynchus tangara from Thraupis episcopus (Passeriformers: Thraupidae). Records from A. chionogaster and T. episcopus represent new hostparasite associations. Mites of this genus were found in Peru for the first time.

Labrisomus philippii (Steindachner, 1866) is a marine fish species of intertidal-subtidal rocky bottom with distribution on the coast of Peru and Chile. 124 specimens of L. philippii were acquired in the Chorrillos Fishmarket, Lima, Peru, between May to September 2008 to evaluate parasitefauna infracommunities. Fish showed a mean length of 19.1 cm (10 cm to 24.5 cm). Parasites were collected and counted employing conventional techniques. Parasite assemblages were higher for endoparasite (99.3%) than ectoparasites abundance (0.70%). The mean parasite species richness as 1.1 (0-5). Forty-seven hosts were not parasited and seventy-seven hosts showed infection at least with one parasite specie. Eight parasites with the following prevalence and mean abundance were found: an unidentified mixosporea (7.2%; 0.1±0.5), the copepod Acanthochondria syciasis (Kroyer, 1863) (4%; 0.04±0.2), three tre...

Pathological lesions caused by acanthocephalans in marine birds are still little known. In this sense, a study of the pathological lesions in the gray gull (Leucophaeus modestus) (Tschudi, 1843) caused by theacanthocephalan Profilicollis altmani (Perry, 1942) Van Cleave, 1947 is presented. Gross lesions weremainly thickening of the intestinal wall in the area of deep penetration by the worm, with white serosalnodules. Microscopically was observed penetration from the parasite's anterior end in the villi andsubmucosa, surrounded by severe caseous necrosis and an inflammatory reaction composed by a moderate number of eosinophils and some multinucleated giant cells, mononuclear cells and peripherally a dense fibrous and vascularized connective tissue. Furthermore, the area between the proboscis and the necrotic tissue presented a number of bacilli basophilic bacteria. Additionally, in adjac...

Introduction: Anemia in children is a public health problem in Peru and in the world. Children are particularly vulnerable to anemia, because of their high growth rate and high iron requirements, presence of parasites, low birth weight and frequent episodes of diarrheal infections. The objective of the present investigation was to evaluate the factors associated with gastrointestinal parasitosis, anemia and school performance in children of the primary level of two schools in Pamplona Alta.Introduction: Anemia in children is a public health problem in Peru and in the world.

 A fecal parasitological study of the population performing artisanal fishing of Terminal Pesquero de Chorrillos (Fishing Terminal of Chorrillos), Province of Lima, Peru, was conducted aiming at determining the prevalence of endoparasites and their relationship with fishing activity. Fecal samples were examined by the Ritchie's Method and the Spontaneous Sedimentation in Tube Technique. The prevalence of endoparasites was 68%. The only pathogenic protozoa found was Giardia intestinalis (syn. G. lamblia) (Lambl, 1859) Kofoid & Christiansen, 1915 with a 16% prevalence. The helminth parasites found included Hymenolepis nana (Culbertson, 1940) and Ascaris lumbricoides (Linnaeus, 1758), both with a 4% prevalence. Commensal parasites found included Endolimax nana (Wenyon & O´Connor, 1917) at a prevalence reaching 40%, followed by Entamoeba coli (Grassi, 1879) with 28% and finally Iod...

Este estudio tuvo como objetivo analizar un caso de alto nivel de infección con acantocéfalos para comprender si el patrón de infección está relacionado con las características biológicas de los hospederos. Se recolectaron acantocéfalos de 33 ejemplares de Rhinella marina (Linnaeus, 1758) de Huanuco, Perú, y luego se utilizó la prueba de rango de Spearmans (r ) para calcular posibles correlaciones entre el tamaños del cuerpo del hospedero y la abundancia de parásitos, y el tamaño del cuerpo del parásito y la abundancia de parásitos. Los helmintos fueron identificados como Pseudoacanthocephalus lutzi (Hamann, 1891). La prevalencia de infección fue del 97,1%. Se recuperó un total de 874 helmintos, con una abundancia media de 24,1 ± 4,7 y una intensidad media de infección de 24,8 ± 4,8. El tamaño del cuerpo del huésped y el tamaño del cuerpo del parásito no se correl...

Rhinella marina es un bufónido grande con hábito nocturno y terrestre, que habita áreas húmedas con cobertura adecuada, con preferencia por hábitat abierto o perturbado como vías, caminos, pastizales bajos y áreas cercanas al asentamiento humano.

El poderío de contaminación de los efluentes domésticos radica en la cantidad de materia orgánica y microorganismos que contienen. El objetivo del presente estudio fue determinar las implicancias de la calidad sanitaria de las playas en la ecología parasitaria del “Muy Muy” Emerita analoga en la costa central del Perú. Se recolectaron 5287 especímenes de E. analoga de 13 playas del departamento de Lima, Perú entre julio del 2001 a junio del 2016. Se analizó la influencia de la calidad sanitaria establecida por la cantidad de coliformes termotolerantes (NMP·100mL-1) en relación a los índices parasitarios, la longitud del cefalotórax y sexo de E. analoga, según fecha y lugar de colecta, y distancia desde la línea de marea. Los parásitos encontrados fueron: Profilicollis altmani (Perry, 1942) Van Cleave, 1947 (Acanthocephala) y Proleptus carvajali (Fernandez & Villalba, ...

This study aimed to determine the prevalence and risk factors associated with bovine fasciolosis in peasant communities of the Huancabamba province (Piura, Peru). In total, 360 samples of bovine faeces were collected in the districts of Huancabamba, Sondor, Sondorillo and Carmen de la Frontera. The stool samples were analysed using the Dennis sedimentation technique. Association of the presence of Fasciola hepatica eggs in the stool with the, sex and district of origin of the animals was evaluated. The results showed that 42.5% (95% CI: 37.3-47.8%) of animals were infected with F. hepatica. The highest probability of contracting fasciolosis in cattle was in the age group of 13-18 months (PR: 2.56; 95% CI: 1.51-4.28) and from the Sondorillo district (PR: 1.41; 95% CI: 1.04-1.94); Furthermore, being male was considered a protection factor (PR: 0.69; 95% CI: 0.53-0.90). The study showed a h...

El presente estudio evaluó la influencia de la estacionalidad en la ocurrencia de ectoparásitos en una población de Rhinella marina Linnaeus, 1758 de la región de Loreto, Iquitos, Perú. Los hospederos fueron colectados durante búsquedas nocturnas activas. Treinta individuos fueron recolectados en la estación seca (septiembre / 2013) y 20 en la estación lluviosa (marzo / 2014). Los hospederos recolectados fueron sometidos a evaluación morfométrica, y posteriormente, fueron examinados para la presencia de ectoparásitos a través del examen de la entera superficie corporal bajo un estereomicroscopio. Sólo una especie de ectoparásito, Amblyomma rotundatum Koch, 1844, se encontró en los hospederos analizados. La prevalencia y abundancia media de A. rotundatum en R. marina en la temporada de lluvias fue mayor que en la estación seca. Sin embargo, la intensidad media de infestaci...

The objective of this work was to evaluate the contamination of public parks in the district of Huánuco, Perú with eggs of Toxocara canis. 32 soil samples were taken in each of 11 parks for a total of 352 samples in May and June of 2014. Parks were selected at random. In each park, 2-3 kg soil was collected according to the double “W” method. Flotation with a saturated sugar solution was used. Samples were considered positive when at least one egg of T. canis was found. Of the 11 parks sampled, T. canis eggs were found in 90.9%. Seven parasites were found along with T. canis in the soil. The sequence of parasite prevalence was in the following descending order: T. canis> Strongylus type eggs of Ancylostoma caninum > A. caninum larvae = Blastocystis hominis > Trichuris vulpis= Entamoeba sp. > Capillaria sp. = Balantidium coli. Parasite richness was 2.45 ± 1.21 (1-4) par...
