Gastrointestinal parasitism is a health issue in livestock, particularly in non-intensive farming systems. This research evaluated the prevalence and risk factors associated with gastrointestinal helminths in goats from three ecosystems in Peru: the Andean shrubland (Ancash), dry forest (Lambayeque), and coastal valley (Lima). The study used a cross-sectional design, with random sampling of goats from extensive production systems in each ecosystem. A total of 819 fecal samples were collected and analyzed using qualitative and quantitative parasitological methods. Additionally, coproculture was performed to identify infective larvae of nematodes. The FAMACHA© index was used to assess anemia levels, while body condition scores were recorded to evaluate the nutritional status of the animals. The highest prevalence was recorded in the Andean shrubland (74.2%), followed by the dry forest (63...

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%) compa...
