    Incidencia de Toxocara cati en felinos domésticos y su efecto en la salud pública en la parroquia de Fátima, cantón Pastaza, provincia de Pastaza
    (2024-08) Pérez Ordoñez, Geovanna Estefanía; Villavicencio Villavicencio, Blanca Jeaneth
    Toxocara cati is a type of roundworm that lives in the intestine and mainly affects domestic cats and other felines. This parasite is transmitted when cats ingest Toxocara cati eggs present in their environment, either through contaminated food or by exploring areas where these eggs are found. Once inside the cat's intestine, the eggs hatch and the larvae move through the animal's body, causing various health problems such as vomiting, diarrhea, weight loss, and in more serious cases, intestinal obstructions. It is important to note that Toxocara cati can also represent a risk of transmission to humans, being capable of causing parasitic infections in people. Because of this, a study was carried out in the Fátima parish, province of Pastaza. The purpose of this study was to determine the incidence in domestic felines and its effect on public health. A survey was carried out to find out the feline population in the parish, resulting in 143 animals, and 104 of them were sampled. The egg diagnosis and quantification methods used were the Flotation method by Willys Molloy and the Mcmaster Camera. The result was 23.07% in domestic felines, a calculation was made in which non-wormed felines had an average of 661 h.p.g., in females an average of 675.33 h.p.g. was found, in puppies an average of 467.66, and in adults an average of 521.6 h.p.g. placing these in a moderate parasitosis on the other hand, the males had an average of 801.33, and the young ones an average of 803.84 h.p.g. finding himself in a severe parasitosis, compromising the patient's life. And having a higher incidence in females (75%), not dewormed (100%), in puppies (54%), young people (25%) and adults (21%) and in children under 6 months and 25% in the owners of The cats.

    Determinación de la titulación de anticuerpos post vacunales en Leucemia Viral Felina mediante ensayo inmunoenzimático de tipo indirecto en gatos de diferentes edades
    (2024-02) Viteri Ortiz, Rosa Noemi; Kelly Alvear, Gerardo Enrique
    Feline Viral Leukemia (ViLeF) is a retrovirus that affects domestic cats to a great extent, causing persistent infections and even death; however, vaccination as a means of prevention avoids the contagion and spread of the virus. For this reason, the research focused on the identification of post-vaccination antibodies in domestic felines by means of an indirect enzyme-linked immunosorbent assay using plasma extracted before and after the application of the vaccine, to identify the increase or decrease of post-vaccination antibodies. According to the results obtained, no statistically significant differences were found in the amount of preand post-vaccine ViLeF antibodies where the scores of the pre-vaccine results of the amount of antibodies (M= 0.06; SD= 0.03) were higher than the scores of the post-vaccine results of the amount of antibodies (M= 0.05; SD= 0.01) t(24)= 1.52, p˂0.005, d= 0.14, d being greater than p value. We sought to identify the relationship between cases positive for ViLeF with factors such as sex, age and reproductive status, omitting the animal's lifestyle, since the samples were obtained from 25 cats rescued by the Municipal Shelter of the city of Ambato. However, the mentioned variables did not show any relation with the increase of antibody titer against ViLeF in domestic cats, where the results obtained in relation to sex showed that the difference of means of both pre-vaccination (M=0.08) and post-vaccination (M=0.05) results in males was 0.03, being the same a negative variation and in females, the means of pre-vaccination (M=0.05) and post-vaccination (M=0.05) results did not show any difference of means. According to age, the results are: 6 - 11 months before - vaccination (M=0.06) and post - vaccination (M=0.05); 1 - 3 years before - vaccination (M=0.06) and post - vaccination (M=0.05) and 4 - 8 years before - vaccination (M=0.06) and post - vaccination (M=0.05), the difference was negative M(dif)= 0.01 in all ranges. Finally, the influence of reproductive status was evaluated and the following results were obtained: Sterilized before-vaccination (M=0.06) and after-vaccination (M=0.05) and Whole before-vaccination (M=0.06) and after-vaccination (M=0.05), in both cases, the variation was -0.01.

    Prevalencia del virus de leucemia (FELV) en gatos domésticos (Felis catus) de la parroquia Fátima de la provincia de Pastaza
    (2023-09) Pérez Amores, Raúl Alberto; Borja Caicedo, Byron Enrique
    The objective of this study was to determine the "Prevalence of the Leukemia virus (FeLV) in domestic cats (Felis catus) of the Fátima parish in the province of Pastaza". For the present investigation, 121 domestic cats were randomly analyzed without age range or sex. They were physically examined and evaluated through a clinical examination. Subsequently, a blood sample of approximately 1 ml of blood (EDTA tube) was taken from each patient and tests were performed to determine whether or not the Feline Leukemia Virus (FeLV) was present or not through rapid immunochromatography tests. For positive cases, laboratory hemograms were performed to determine possible hematological alterations. The information obtained was recorded, the data were tabulated and the results were correlated with the risk factors present in the environment for the prevalence of the disease. Of the 121 samples analyzed, 9 positive cases were obtained, showing a prevalence of 7.44% of Feline Leukemia Virus (FeLV) in domestic cats (Felis catus); no significant statistical relationship (p≥0.05) was demonstrated between risk factors such as sex, age, reproductive status, cohabitation with other cats, and sanitary calendar with the presence of the disease. Through the samples analyzed from the positive cases, hematology determined the alterations associated with the presence of the disease in the positive cases, demonstrating the affectation of the virus on the bone marrow and hematopoietic cells.

    Análisis de la eficacia del aceite esencial de té verde (Camellia sinensis) como aromaterapia en la reducción de estrés en gatos de consulta
    (2023-09) Guevara Solís, Samantha Betzabé; López Villacís, Isabel Cristina
    The development of ethology as a scientific discipline has allowed the development of practices that help improve the human-cat relationship and animal welfare. It is for this reason that the new trends in the handling of domestic cats lie in promoting empathy in the respectful handling of domestic cats and the generation of positive experiences when going to the vet, thus avoiding the generation of stress or anxiety. Therefore, a study is proposed to analyze the efficacy of green tea (Camellia sinensis) essential oil as aromatherapy in reducing stress in consulting cats. The proposed study was carried out at the Pet's Home Veterinary Clinic, which is in the Tungurahua Province of the Ambato Canton. The reference population consisted of 45 domestic cats. The sample selection was divided into 3 experimental groups, each of 15 cats that were in healthy conditions with aromatherapy exposure to different concentrations of green tea (5%, 10% and 15%). The experiment model applied to validate the hypothesis responds to the name of Complete experimental design by means of Fisher's test. In conclusion, I have to assert that; green tea as aromatherapy has a relaxing effect in cats based on the p value (0.000 where p value < 0.05) due to the significant behavioral changes between the results of its application.

    Evaluación de inducción en cámara con el método directo e indirecto sobre el dolor y recuperación postanestesica en gatos agresivos.
    (2017) Coronado Reyes, María Mercedes; Lozada, Efraín
    The main objective of the present investigation is to evaluate the induction in camera with the direct and indirect method on pain and postanesthetic recovery in aggressive cats. In 64 aggressive domestic cats females and males with a weight range from 2.5 kg to 4.5 kg. They were submitted to two methods of direct and indirect anesthetic induction. They were divided into four experimental groups. In each method the protocol was used, fentanyl at doses of 5 and 8 ug / kg, after 3min of Preoxygenation that was maintained for the 4 groups. In direct induction, 8% sevoflurane was administered with oxygen at 4 lt / min, initially, the highest flow is given for every 30 seconds, and it is gradually decreased (1CAM) until the minimum maintenance dose of 1 CAM. Indirect Induction was administered 8% sevoflurane conveyed with oxygen at 4 lt / min, initially, the lowest flow was given for every 30 seconds, and gradually increased (1CAM) until reaching the maximum dose of 8 CAM . Subsequently neuroleptoanalgesia is performed with Midazolam of 0.4 mg / kg IM, and fentanyl at 5ug / kg or 8ug / kg IV, respectively. At the end of the surgical procedure, the speed and quality of recovery, the level of consciousness through the modified Glasgow scale, and the BODUCATU multidimensional scale were evaluated for postoperative pain assessment. Both anesthetic methods behaved similarly in terms of induction velocity in the chamber and the quality was better in the indirect method. In the rate of recovery in the chamber, we observed with the direct method was a faster recovery independent of the dose of fentanyl and an acceptable recovery quality independent of the method used. Concerning the level of consciousness during recovery, the indirect method was superior, regardless of the dose of fentanyl used. In the Botucatu multidimensional scale the T4 was the best
