Currently, there are not enough formal studies on parasitological fauna in backyard birds in Ecuador, for this reason the present work aims to contribute with knowledge regarding the prevalence and parasitic incidence of backyard poultry production in parish San José, province of Pastaza, likewise, describe the importance of sustainable and sustainable production that guarantees food safety because to strengthen both animal health and the sanitary management of animals by identifying risk factors to prevent them through sanitary control management, therefore, the objective of the present investigation was to identify the main gastrointestinal parasites associated with risk factors and zoonotic interest in backyard birds from rural areas of the tropics. Fecal samples were collected from 80 birds (roosters and hens) of different ages under a backyard breeding system. The samples were collected at random. For laboratory analysis, the samples were subjected to flotation and washing tests and the Mc Master technique. The prevalence of parasites could be determined with a value of 91.25%, depending on sex, the positive parasite prevalence in females was high (60%). Regarding the identification of parasites, the prevalence of: Hymenolepis setigera and Capillaria spp was reported with 27% respectively, followed by Eimeria spp (26,3%). Depending on age; The parasite prevalence was higher in birds older than 12 months. Finally, the Odds Ratio values were greater than 1, in factors such as deworming, feeding, and housing, which is considered a viable irrigation factor, favoring parasite infestation.

This study reviews the resistance of gastrointestinal parasites in cattle in Ecuador to the use of anthelmintics, through a bibliographic review of scientific publications and national reports. The objective is to provide an updated overview of parasite species prevalence and the effectiveness of anthelmintic treatments, considering the geographical, climatic, and biological variations across different regions of the country. The specific objectives include: 1) Determining the number of helminth species present in cattle fecal samples before and after treatments with various drugs. 2) Identifying the most prevalent gastrointestinal parasite species. 3) Analyzing deworming protocols, considering the diversity of helminths, the time of year, and the duration of treatment effectiveness in each region. The study covered several regions of Ecuador, including the coast, highlands, and the Amazon, each with distinct climatic and geographical conditions that influence parasite prevalence and treatment effectiveness. In the coastal region, provinces such as Manabí, Guayas, and El Oro, with warm and humid climates, promote parasite presence. In the highlands, areas like Pichincha, Chimborazo, and Azuay, with cooler climates and higher altitudes, present different patterns of parasitic incidence. In the Amazon, provinces such as Napo, Sucumbíos, and Morona Santiago are characterized by their biodiversity, which facilitates the prevalence of various parasitic species. This analysis provides key information to optimize parasite control strategies in cattle farming in Ecuador, contributing to the development of more sustainable and effective practices that improve animal health and increase livestock productivity in the country.
