Identificación y prevalencia de artrópodos ectoparásitos asociados en caprinos de raza criolla en la provincia de Santa Elena
(2024-08) Chico Mayorga, María Fernanda; Almeida Secaira, Roberto Ismael
Goat breeding has been gaining strength in recent years in the country. In order to be successful in animal production, many factors must be taken into account. For example, one of them is ectoparasites. This problem can cause diseases and complications in animals and therefore ends in economic losses. Therefore, the research was carried out with the objective of identifying the prevalence of ectoparasites in Creole goats in Río Verde, province of Santa Elena. Ectoparasites were collected from 52 female goats, and then the samples were placed in jars with 70% alcohol to be transported to the laboratory where the identification analysis was carried out using a stereoscope. The result was the presence of the genus Rhipicephalus linnaei, a type of tick not previously described in Ecuador and known to attack the canine species. In addition, in terms of prevalence, it was determined that there is a 15% infestation of ectoparasites in 8 of 52 goats. In conclusion, it is inferred that the genus Rhipicephalus linnaei has evolved looking for larger hosts such as goats and has spread to reach Ecuador.
Prevalencia de Giardia spp en caninos domésticos y su repercusión en la salud pública en la comunidad Rumiñawi Chico, Provincia de Tungurahua
(2023-09) Culcay Zurita, Bryan Andrés; Almeida Secaira, Roberto Ismael
The objective of this research topic was to identify the prevalence of Giardia spp in domestic canines and its impact on public health in the Rumiñawi chico community, Tungurahua Province, for which 51 samples were processed by performing a serial sampling, that is, 3 per canine. To increase the rate of positive results, using the Faust flotation method (Zinc Sulfate at 33.3% density 1.18), they were divided into two categories: sex (males and females) and age (puppies and young), followed by collecting samples from the owners divided into age ranges to perform Giardia spp specific antigen tests in a private clinical laboratory, in addition the Mcmaster camera was used to count cysts per gram of feces q.p.g to obtain the degree of parasitosis using ranges between slight , moderate and severe, data tabulation was performed through descriptive statistics using the Chi-square test in addition to calculations to determine the average number of cysts obtained in the chamber. Giardia spp cysts observed under the microscope with 10x and 40x lenses were obtained, obtaining a prevalence of 47.05%, puppies are more susceptible to contracting the parasite, but not for young canines, the zoonotic relationship that exists between canines and dog owners was demonstrated. the pets yielding positive results in the antigen test, the count of the cysts was classified by averages and the degree of parasitosis of each category was determined.
