Item Identificación de los factores de riesgo asociados a enteroparásitos en gallinas criollas (Gallus gallus domesticus) de traspatio en las zonas rurales de la parroquia San José, de la provincia de Pastaza, Ecuador(2025-02-11) Cuvi Cuenca Keyla Paola; Rodríguez Haro Cecilia ElizabethCurrently, 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.Item Factores de riesgo asociados a enfermedades causadas por nematodos y cestodos endoparásitos en cerdos en el Centro de Faenamiento Pelileo(2024-10) Lascano Gualpa, Rosa Obdulia; Almeida Secaira, Roberto IsmaelIncidence of internal parasites affects pig production, which not only causes significant economic losses in livestock production worldwide, but also implies a risk to the health of people involved in this type of industry and consumers of meat. of pork. Thus, the present study was carried out in order to analyze the risk factors associated with diseases caused by endoparasite nematodes and cestodes in pigs at the Pelileo Slaughter Center during the period 2023-2024. Diagnosis of parasite species was carried out following the procedures established by the Ministry of Agriculture, Livestock, Agriculture and Fisheries with its attached entity AGROCALIDAD (Agency for Phyto and Zoosanitary Regulation and Control). The species were found: Ascaris sp. and Hyostrongylus sp. (Nematoda) and larval phase of Cisticercus tenuicollis and the hydatidic cyst (Cestoda) mainly associated with the liver of pigs. The highest prevalence was observed for Ascaris sp. infections (21.07%) followed by larvae of Echinococcus granulosus (19.73%) and Hyostrongylus sp. (5.87%), while double Ascaris-Hyostrongylus infections were relatively low (1.33%) as well as infections by hydatidic cysts (1.07%). Regarding risk factors, it was found that age was associated with the prevalence of parasites, being higher in pigs less than 1 year old. Regarding the location within the host, parasites were mainly found in organs that make up part of its biological cycle. On the other hand, no association was found with the sex of the host. According to the results, the prevalence of Ascaris and metacestods of Echinococcus seems to be related to herd management factors, however, this aspect requires investigation.
