Parásitos gastrointestinales en el mono choro cola amarilla (Lagothrix flavicauda) de vida silvestre en el distrito Corosha, Amazonas, Perú

The aim of this study was to identify gastrointestinal parasites present in wild yellow-tailed woolly monkey (Lagothrix flavicauda) in the Corosha district, Amazonas department, Peru. Twenty fecal samples were collected immediately after defecation. Each sample was separated into two portions to be fixed in 10% formalin at 65 ºC and in polyvinyl alcohol (PVA). The samples were analyzed using the Direct, Ritchie, Sheather Sugar, Gomori trichrome staining and modified Ziehl-Neelsen staining methods. The gastrointestinal parasites found were four nematodes (Capillaria sp, Ancylostoma sp, Strongyloides cebus, Strongyloides sp), one cestode (Paratriotaenia oedipomidatis), one acantocephalus (Prosthenorchis elegans) and three protozoa (Entamoeba coli, Cryptosporidium sp, Coccidia sp. Coccidia sp is a new genus reported for Lagothrix flavicauda.El objetivo del estudio fue identificar parásitos gastrointestinales presentes en monos choro cola amarilla (Lagothrix flavicauda) de vida silvestre en el distrito de Corosha, departamento de Amazonas, Perú.

Canes domésticos como reservorio de Leptospira spp y Toxoplasma gondii en una comunidad campesina del Bosque nuboso del noreste de Perú

The aim of this study was to identify the role of domestic dogs as reservoirs of Leptospira spp and Toxoplasma gondii in the Rural Community of Corosha, department of Amazonas, Peru, through the analysis of prevalence and epidemiological characteristics, as well as tenure associated with dog positivity. A survey was carried out on the dog owners and blood samples were taken. In total, 55 samples were analyzed by the Microscopic Agglutination Test (MAT) for the identification of anti-Leptospira spp antibodies and 62 samples with the Indirect Hemagglutination technique (HAI) for anti-T. gondii. The seroprevalence of Leptospira spp was 82.3%, detecting antibodies against the Grippotyphosa (58.2%), Icterohaemorrhagiae (54.6%), Pomona (40.0%), Canicola (32.7%), Bratislava (30.9%) and Georgia (21.8%) serovars. Dogs with access to the river showed a higher prevalence of Leptospira (94.9%) compared to individuals without access (68.8%) (p<0.05). Likewise, 37.1% of the evaluated dogs were seropositive for T. gondii. The study reveals the circulation of Leptospira spp and T. gondii in domestic dogs of the rural community of Corosha.El objetivo del estudio fue identificar el rol de los canes domésticos como reservorios de Leptospira spp y Toxoplasma gondii en la Comunidad Campesina de Corosha, departamento de Amazonas, Perú, mediante el análisis de prevalencia y de las características epidemiológicas, así como de tenencia asociadas a la positividad de los canes. Se realizó una encuesta a los tutores de los canes y se tomaron muestras sanguíneas. En total, 55 muestras fueron analizadas por la Prueba de Aglutinación Microscópica (MAT) para la identificación de anticuerpos anti-Leptospira spp y 62 muestras con la técnica de Hemaglutinación Indirecta (HAI) para anticuerpos anti-T. gondii. La seroprevalencia de Leptospira spp fue de 82.3%, detectándose anticuerpos contra los serovares Grippotyphosa (58.2%), Icterohaemorrhagiae (54.6%), Pomona (40.0%), Canicola (32.7%), Bratislava (30.9%) y Georgia (21.8%). Los canes con acceso al río mostraron mayor prevalencia de Leptospira (94.9%) en comparación a los individuos que no tienen acceso (68.8%) (p<0.05). Asimismo, 37.1% de los canes evaluados resultaron seropositivos para T. gondii. El estudio da a conocer la circulación de Leptospira spp y T. gondii en canes domésticos de la comunidad campesina de Corosha

Tropical field stations yield high conservation return on investment

Conservation funding is currently limited; cost-effective conservation solutions are essential. We suggest that the thousands of field stations worldwide can play key roles at the frontline of biodiversity conservation and have high intrinsic value. We assessed field stations’ conservation return on investment and explored the impact of COVID-19. We surveyed leaders of field stations across tropical regions that host primate research; 157 field stations in 56 countries responded. Respondents reported improved habitat quality and reduced hunting rates at over 80% of field stations and lower operational costs per km2 than protected areas, yet half of those surveyed have less funding now than in 2019. Spatial analyses support field station presence as reducing deforestation. These ‘earth observatories’ provide a high return on investment; we advocate for increased support of field station programs and for governments to support their vital conservation efforts by investing accordingly
