Item Relato de caso: obstruçâo intestinal por fitobezoar em bovino(2024-08-28) Menezes, Bruna Gomes Calaça; Araújo, Carolina Akiko Sato Cabral de; http://lattes.cnpq.br/5868230858347175; http://lattes.cnpq.br/6999600915457837The present work presents the activities developed during the Mandatory Supervised Internship (ESO) in the area of medical and surgical clinic for large animals, divided into two parts: the first at the Cattle Clinic of Garanhuns (CBG) of the Federal Rural University of Pernambuco, located in Garanhuns, Pernambuco, from 04/01/2024 to 05/31/2024 from, Monday to Friday, totaling 344 hours of internship. The second part was carried out at the Large Animal Outpatient Clinic (AGA) of the Department of Veterinary Medicine (DMV) of the Federal Rural University of Pernambuco, during the period from 06/03/2024 to 06/14/2024, from Monday to Friday, totaling 80 hours of internship. During the ESO period, supervision was provided by Ms. Dr. Carolina Akiko Sato Cabral de Araújo, adjunct teacher at UFRPE, and by two supervisors, one for each phase of activities, respectively: Dr. Maria Isabel de Souza and Prof. Dr. Carolina Akiko Sato Cabral de Araújo. The completion of the ESO in the Veterinary Medicine course is crucial to provide practical experience, consolidate theoretical knowledge, develop clinical skills, and prepare students for professional practice. Therefore, the objective of this work is to describe the activities carried out during the ESO period, as well as to report a clinical case that was followed during this period of a cow that died due to intestinal obstruction caused by a phytobezoar located in the initial portion of the duodenum.Item Uso da gonadotrofina coriônica equina para melhora dos resultados da IATF em fêmeas Nelore(2024-03-04) Botelho, Caio Cézar Vergetti Albuquerque; Bartolomeu, Cláudio Coutinho; http://lattes.cnpq.br/7619056086707716This activity was carried out on several farms in the interior of Pernambuco from 10/02/2023 to 12/21/2023 with the aim of improving knowledge in the field area, such as a medical clinic and a laboratory analyzing brucellosis tests in cattle. In horses, it was only used in the medical-clinical area. The biggest focus was on bovine reproduction with fixed-time artificial insemination (IATF). During the internship period, farms in the forest and rural areas of Pernambuco were visited, mainly working with beef cattle. Gestational diagnoses were made with several different age ranges, protocol initiations, and artificial inseminations. In the surgical clinic area, surgeries such as castration in horses, vulvoplasty in heifers, and hematoma drainage in calves were experienced. Laboratory and field tests were carried out, with laboratory tests for brucellosis using the AAT (buffered acidified antigen) method and field tests focused on tuberculosis. At the animal exhibition, it was possible to receive documents (GTA, brucellosis test, equine infectious anemia test, and vaccination card) to receive the animals that arrived at the Cordeiro exhibition park. The birth of a Girolando female was observed. Chapter II included a literature review with the title “Use of equine chorionic gonadotropin to improve TAI results in Nelore females” in which the work reaffirms the effectiveness of using eCG in postpartum cows with low body scores, helping TAI protocols as a tool to enhance and improve follicular development and maturation.Item Impacto do estresse oxidativo na maturação de oócitos in vitro: efeito antioxidante do tanino(2023-09-05) Ramires, Millena Mary da Silva; Souza, Andreia Fernandes de; Batista, André Mariano; http://lattes.cnpq.br/5615914349535394; http://lattes.cnpq.br/6354486109796073; http://lattes.cnpq.br/3731466705214441In vitro conditions can end up promoting damage to oocytes due to oxidative stress, compromising their quality and success rates in embryo production. Research has reported that supplementing the in vitro maturation medium with different antioxidants helped mitigate damage from oxidative stress. Thes, tannin, which has antioxidant action, arouses interest in studies on its antioxidant potential in oocyte maturation. This study was carried out to promote greater scientific knowledge about the action of tannin on oocyte maturation. Ovaries from adult cows obtained from a commercial slaughterhouse were used. These antral follicles were aspirated to select oocytes with homogeneous cytoplasm and one or more compact layers of cumulus cells. After maturation, these cells were removed by pipetting for subsequent preparation of slides and reading regarding the cellular meiotic stage. The experimental groups consist of different concentrations of Tannin (Sigma), being: TA0 = no addition of Tannin (control); TA1 = 1 μg/mL Tannin; TA10 = μg/mL of Tannin and TA100 = 100 μg/mL of Tannin. With the experiment, similar maturation rates were obtained for all treatments tested: TA0 (79.31%) TA1 (72.63%) TA10 (80.95%) TA100 (73.11%). Regarding the cleavage rates obtained after fertilization, it was observed that treatments TA0 (73.13%) TA1 (63.38%) TA10 (70.90%) presented similar results, while treatment T100 (47.91 %) showed a deleterious effect with a significant decrease in cleavage rates. Therefore, it is recommended that tannin supplementation be carried out in amounts below 100 μg/mL.Item Coxielose em ruminantes e a febre Q na saúde pública no Brasil(2021-09-17) Zache, Eduardo; Torres, Alexandre Augusto Arenales; http://lattes.cnpq.br/5145322907663650; http://lattes.cnpq.br/9715170506304327Q fever is a zoonosis of worldwide distribution caused by Coxiella burnetii, a gram-negative obligate intracellular bacterium of the order Legionellales, which has been classified as a potential bioterrorism agent. Thus, the present study aims to perform a literature review on Q fever and coxiellosis, with emphasis on its close relationship to public health, due to its zoonotic nature, in addition to its economic importance for national livestock. Cattle and small ruminants represent the most frequent sources of infection in humans, with inhalation of contaminated aerosols from infected animal products being the main form of transmission. The high occupational risk is related mainly to cattle and small ruminant breeders and veterinarians, even people with sporadic contact with animals, such as employees in veterinary clinics. Infections in humans are usually asymptomatic, but can evolve into serious complications such as endocarditis, which can be fatal if not treated appropriately. In ruminants the most important clinical manifestations are reproductive disorders such as abortion, stillbirth fetus, endometritis, infertility and mastitis, but the agent has also been identified in cattle with endocarditis. The clinical diagnosis is difficult, due to the nonspecificity of the clinical signs. Specific indirect diagnostic tools such as the indirect microimmunofluorescence test is considered a reference technique for humans, however for ruminants the molecular method of polymerase chain reaction (PCR) is a reliable method to detect the elimination of the agent in body fluids (feces, milk and vaginal mucus) that may be intermittent. The prophylactic combination of doxycycline and hydroxychloroquine has been shown to be effective in preventing endocarditis and is indicated in the presence of risk factors in humans. In animals, the use of antimicrobials has not been effective. In recent years, several cases of C. burnetii infection in humans and animals have been reported in Brazil, with evidence of Q fever circulating in humans in the southeast and northeast regions, and in animals in the southeast, central-west and northeast regions. The Ministry of Agriculture, Livestock and Supply classifies the disease in category 3 (three) of the list of diseases of mandatory notification to the Veterinary Service, however, it is not recognized by the Brazilian Ministry of Health as of mandatory notification in humans. With all zoonotic diseases, the control of the disease in animals and the interdisciplinary following the principles of One Health, will directly influence the results observed in humans.Item Coronavírus bovino: sua relevância na saúde animal e pública global(2021-10-27) Beserra, Lucas Alencar Fernandes; Silva, José Augusto Bastos Afonso da; http://lattes.cnpq.br/9754109726295756; http://lattes.cnpq.br/6178148321524675Bovine coronavirus (BCoV) is a member of the coronaviridae family. It is an important pathogen with high prevalence worldwide. This virus, a pneumoenteric agent, is responsible for the occurrence of three distinct clinical syndromes, described respectively as diarrhea in calves, dysentery in adult animals and respiratory tract affection in cattle of all ages. The presence of this virus in the herd causes substantial economic losses, also, in animal welfare and in the health of the herd. Thus, the objective of this work is to demonstrate the main characteristics of BCoV, as well as describe the occurrence of this agent in other species of domestic and wild ruminant animals. In addition, highlight the coronavirus as a zoonotic pathogen in the context of public health. Coronary virus in cattle is characterized by its enteropathogenic and respiratory forms, symbolized respectively by mucohemorrhagic enterocolitis in calves (EBCoV-CD), dysentery in adult animals (EBCoV-WD) and interstitial pneumonia (RBoV) mainly in calves. Although this agent is considered a specific pathogen of domestic cattle, its occurrence is also described in other species of domestic and wild ruminants, as well as in humans. At the interface between animals and humans, coronavirus is described as an infectious, zoonotic and emergent disease, this agent being described as the only member of the order Nidovirales to cause disease in humans. In this context, several species are incriminated as intermediate hosts in the transmission mechanism to humans, for example, dromedary camels in the transmission of MERS-COV. The role of cattle in the context of intermediate host or reservoir of this virus for humans is still poorly understood, such as the susceptibility and transmission of SARS-CoV-2. However, one of the enteric coronavirus strains in humans (HCoV-OC43) would have evolved from ancestral strains of the bovine coronavirus, which crossed the interspecies barrier and, consequently, established the infection in humans. Thus, we can consider the diseases caused by BCoV as important from an economic point of view, sanitary in the welfare of the herd, in addition to the importance of this agent in the zoonotic context, thus enabling risks to animal and human health.Item Ressincronização da ovulação em fêmeas bovinas durante protocolo de IATF em estação de monta(2022-06-07) Silva, Kleber Juliano Pessoa Oliveira; Batista, André Mariano; http://lattes.cnpq.br/5615914349535394; http://lattes.cnpq.br/7430405045921963Item Produção in vitro de embriões bovinos: da OPU à TE revisão de literatura(2021-07-13) Pecly, Diogo Torreão; Batista, André Mariano; http://lattes.cnpq.br/5615914349535394; http://lattes.cnpq.br/1666234601724127This report reports activities carried out during the immersion of the student in the routine of two companies in the area of bovine reproduction, totaling 420 hours, in the context of the Mandatory Supervised Internship. FertVet Consultoria Veterinária, specialized in artificial bovine insemination, has workplaces spread over dozens of municipalities in the Northeast region, mainly in the states of Sergipe and Bahia. Meanwhile, the company Nordeste In Vitro, operates mainly in the in vitro production of embryos in Sergipe, Pernambuco, Alagoas and Rio Grande do Norte. The student's practices were directly supervised by a veterinary director in each company. Respectively, veterinarians Felipe Costa Almeida and Lucas Carvalho Pereira. The activities carried out focused on the reproductive monitoring of the bovine female, from the diagnosis of the reproductive status through ultrasonography, through the estrus induction and synchronization protocols; fixed-time artificial insemination (IATF), ultrasound-guided follicular aspiration (OPU), in addition to all stages of in vitro embryo production, up to transfer to recipients. In addition to the practices, a literature review of the technical and scientific aspects of the in vitro production process of bovine embryos was carried out. The Mandatory Supervised Internship is a crucial and defining part of the veterinarian training process, when a theory, a practice and aspirations for the labor market are identified. With regard to reproductive techniques in cows, the focus of this work, ESO serves the understanding of general management (step by step) within a farm, of the logistics of a field veterinarian on the way to enter the labor market.
