Item type: Item , Avaliação morfométrica do núcleo de células neoplásicas mamárias malignas de cadelas(Universidade Federal de Goiás, 2020-03-02) Rodrigues, Arthur Perillo; Martins, Danieli Brolo; http://lattes.cnpq.br/2159963349521553; Menezes, Liliana Borges de; http://lattes.cnpq.br/2012543423092393; Miguel, Marina Pacheco; http://lattes.cnpq.br/3078760368293415; Miguel, Marina Pacheco; http://lattes.cnpq.br/3078760368293415; Melo, Fabiana Cristina Silveira Alves de; http://lattes.cnpq.br/4706202969725344; Costa, Cesar Augusto Sam Tiago Vilanova; http://lattes.cnpq.br/5210581114650829The study of cell morphology, as well as nuclear measurement, is important in the histopathological evaluation of breast cancer in female dogs, as well as in women. Bearing in mind that one of the parameters for assessing the degree of malignancy of neoplasms is nuclear pleomorphism. An evaluation of nuclear morphometry can be done with the help of bioimaging software, facilitating the analysis of larger numbers of cases, using subjectivity among observers for quantitative values, low and easy to use. Objective: perform nuclear morphometry in malignant breast neoplasms in female dogs and verify the applicability of Feulgen stain in this analysis. Material and methods: for nuclear analysis, photomicrographs of bitches' breast cancer slides, screen capture (400X magnification), use of a microscope with coupling camera (Leica® DMC 2900) and the ImageJ software (NIH Image 1.52d) to display the nuclear parameters: area, perimeter, Feret and circularity. Results: Carcinomas had the highest mean (85.40µm2 ± 0.3159) and the average perimeter (48.33µm2 ± 0.1217), when compared to complex and tubulopapillary carcinoma (P <0.0001). Thus, the largest nuclear measures can be associated with malignant neoplasms with a higher degree of malignancy. Keywords: Breast cancer, feulgen, nuclear morphology.Item type: Item , Hipertensão arterial sistêmica em cães portadores de doença renal crônica: estudo multicêntrico(Universidade Federal de Goiás, 2020-08-31) Pires, Hugo Cardoso Martins; Giovaninni, Luciano Henrique; Martins, Danieli Brolo; Fioravanti, Maria Clorinda Soares; http://lattes.cnpq.br/8772502020076257; Fioravanti, Maria Clorinda Soares; Veado, Júlio Cesar Cambraia; Crivellenti, Leandro ZuccolottoEmbargoItem type: Item , Soroprevalência e fatores de risco para neosporose caprina no estado de Goiás, região do Cerrado brasileiro(Universidade Federal de Goiás, 2024-07-29) Paula, Lorrayne Honório de; Monteiro, Caio Marcio de Oliveira; http://lattes.cnpq.br/2496419306394657; Oliveira, Vanessa Silvestre Ferreira de; http://lattes.cnpq.br/6090098982472156; Teixeira, Weslen Fabricio Pires; http://lattes.cnpq.br/1222753642148629; Teixeira, Weslen Fabricio Pires; http://lattes.cnpq.br/1222753642148629; Felippelli, Gustavo; http://lattes.cnpq.br/2236741546847014; Pascoal, Lívia Mendonça; http://lattes.cnpq.br/9516000855522978Goat farming is growing in Goiás, providing jobs, income and economic development for the state. While attention to health care is essential to avoid factors that negatively affect herd productivity, etiological agents cause economic losses in animal production. Considered one of the main parasitic agents that promote reproductive problems, including abortions in female cattle, Neospora caninum is an obligate intracellular protozoan responsible for economic losses in goat farming on different continents. However, despite its epidemiological importance within the goat species, there are still no studies on the distribution of this parasite in this animal species in the state of Goiás, a fact that motivated the proposal of the present research, with the objective of evaluating the occurrence of N. caninum infection in goats. For this purpose, 781 serological samples of goats obtained by the official service of the Goiás Agricultural Defense Agency (AGRODEFESA) from all regions of the state were analyzed. The samples were subjected to anti-N. caninum antibody (IgG) testing using indirect immunofluorescence assay (IFAT). Data on sex, age of animals, property size, water source, breed, breeding system, purpose (meat, milk or mixed), and presence of domestic and wild canines were obtained at the time of sampling. The results of the immunofluorescence test revealed that 18.56% (145/781) of the samples were positive. Caprine neosporosis is distributed in all mesoregions evaluated in the state of Goiás, with higher seropositivity rates for N. caninum in the Northwest 27.83% (32/115), North 26.59% (25/94) and Central 23.48% (31/132) mesoregions. The breeding system, purpose, carcass disposal and veterinary assistance were the risk factors statistically associated with the occurrence of neosporosis in goats.Item type: Item , Atividade carrapaticida do fluralaner sobre Rhipicephalus linnaei e Rhipicephalus sanguineus in vitro(Universidade Federal de Goiás, 2026-03-02) Faria, Laura Cristina Ferreira; Krawczak, Felipe da Silva; Lopes, Welber Daniel Zanetti; Monteiro, Caio Márcio de Oliveira; http://lattes.cnpq.br/2496419306394657; Monteiro, Caio Márcio de Oliveira; Ferreira, Lorena Lopes; Santos, Mayara Macêdo BarrozoEmbargoItem type: Item , Ultrassonografia e histopatologia do fígado de bovinos da raça Pantaneiro intoxicado experimentalmente pelas favas do tamboril (Enterolobium contortisiliquum)(Universidade Federal de Goiás, 2026-09-25) Monteiro, Milena Coelho; Borges, Naida Cristina; http://lattes.cnpq.br/9181279951885005; Cunha, Paulo Henrique Jorge da; http://lattes.cnpq.br/3363890096623194; Cunha, Paulo Henrique Jorge da; http://lattes.cnpq.br/3363890096623194; Pereira, Cristiane Da Silva; http://lattes.cnpq.br/1724375293192382; Martins, Apostolo Ferreira; http://lattes.cnpq.br/0959080083251268ResumoItem type: Item , Inativação fotodinâmica para controle de agentes causadores da mastite bovina(Universidade Federal de Goiás, 2025-08-01) Pires, Luiz Henrique Barbosa; Borsanelli, Ana Carolina; http://lattes.cnpq.br/4344854096706983; Gonçalves, Pablo José; http://lattes.cnpq.br/0515343409614452; Souza, Guilherme Rocha Lino de; http://lattes.cnpq.br/1127532567066692; Souza, Guilherme Rocha Lino de; http://lattes.cnpq.br/1127532567066692; Freitas, Alysson Benite de; http://lattes.cnpq.br/8468761118527440; Franchi, Leonardo Pereira; http://lattes.cnpq.br/8068976548504815Bovine mastitis, an inflammation of the mammary gland in dairy cows, is frequently associated with bacterial infections, negatively impacting milk quality, animal welfare, and public health. The disease can manifest in clinical, subclinical, or chronic forms, causing substantial economic losses in dairy production due to reduced milk yield and product devaluation. Conventional treatment relies on antimicrobial use; however, excessive application of these drugs contributes to the emergence of bacterial resistance, threatening animal and human health. This study aimed to evaluate the efficacy of Antimicrobial Photodynamic Therapy (aPDT) using palladiummetalated porphyrins (Porf@DPPE, Porf@DPPP, Porf@DPPB, and Porf@DPPF) against bacteria isolated from mastitis cases. The photosensitizers were tested against Gram-positive and Gram-negative strains, with analysis of antimicrobial susceptibility and synergy with sulfonamides. Antimicrobial susceptibility testing demonstrated potential for optimizing therapeutic protocols to combat pathogenic resistance. Results revealed greater aPDT efficacy against Gram-positive bacteria, with significant inhibition at concentrations between 6.25–100 μM. The Porf@DPPP compound stood out for its broad-spectrum action, including activity against Gram-negatives (25–100 μM). The combination of aPDT and sulfonamides reversed the resistance exhibited by Escherichia coli against the antimicrobial after 30 minutes of irradiation, demonstrating a synergistic effect. DNA integrity analysis confirmed post-aPDT genomic damage, suggesting oxidative mechanisms as the basis for microbial inactivation. It is concluded that aPDT is effective against mastitis-associated pathogens and can be integrated with antimicrobials as a promising strategy for controlling resistant cases. Future studies should focus on evaluating in vivo toxicity, optimizing dosages, and integrating with preventive measures like strict milking hygiene and health management to enable practical application. This multifactorial approach, combined with responsible antimicrobial use, reinforces the promotion of One Health, connecting animal, human, and environmental health for sustainable and safe milk production.Item type: Item , Associação das espessuras do coxim digital, da sola e da gordura corporal dorsal determinadas ultrassonograficamente em vacas Girolando(Universidade Federal de Goiás, 2023-07-31) Venancio, Marianna Traguetto; Borges, Naida Cristina; http://lattes.cnpq.br/9181279951885005; Queiroz, Paulo José Bastos; http://lattes.cnpq.br/6877150287412440; Cunha, Paulo Henrique Jorge da; http://lattes.cnpq.br/3363890096623194; Cunha, Paulo Henrique Jorge da; http://lattes.cnpq.br/3363890096623194; Borges, José Renato Junqueira; http://lattes.cnpq.br/3586382943482522; Pereira, Cristiane da Silva; http://lattes.cnpq.br/1724375293192382EmbargadoItem type: Item , Viabilidade de amostras sanguíneas em diferentes tempos e temperaturas para hematologia, bioquímica e hemogasometria de bovinos saudáveis(Universidade Federal de Goiás, 2021-07-20) Iara, Italo Henrique do Nascimento; Penido, Paula Maria Pires do Nascimento; Borges, Naida Cristina; Martins, Danieli Brolo; http://lattes.cnpq.br/2159963349521553; Martins, Danieli Brolo; Noronha Filho, Antônio Dionísio Feitosa; Cunha, Paulo Henrique Jorge daEmbargadoItem type: Item , Creatinina sérica como fator preditivo de óbito em cães atendidos em situação de urgência ou emergência(Universidade Federal de Goiás, 2024-11-11) Mamede, Paulo Henrique Lino; Braga, Sandro de Melo; Fioravanti, Maria Clorinda Soares; Silva, Marco Augusto Machado; http://lattes.cnpq.br/2134206254307043; Silva, Marco Augusto Machado; Arnhold, Emmanuel; Veridiane da Rosa Gomes, Veridiane da RosaEmbargadoItem type: Item , Abordagem diagnóstica da urolitíase em cães e gatos(Universidade Federal de Goiás, 2025-02-14) Fraga, Heloisa Alvim Rodrigues; Botelho, Ana Flavia Machado; http://lattes.cnpq.br/7634869593114668; Castro, Luma Tatiana Silva; http://lattes.cnpq.br/7632876278053145; Fioravanti, Maria Clorinda Soares; http://lattes.cnpq.br/8772502020076257; Fioravanti, Maria Clorinda Soares; http://lattes.cnpq.br/8772502020076257; Borges, Naida Cristina; http://lattes.cnpq.br/9181279951885005; Souza, Saura Nayane de; http://lattes.cnpq.br/9991507572546807Embargada.Item type: Item , Avaliação do trânsito gastrointestinal de cães por meio de radiografias contrastadas com Esferas de Polietileno Impregnadas com Bário (BIPS)(Universidade Federal de Goiás, 2025-02-19) Souza, Murilo Rodrigues de; Silva, Marco Augusto Machado; http://lattes.cnpq.br/2134206254307043; Botelho, Ana Flávia Machado; http://lattes.cnpq.br/7634869593114668; Botelho, Ana Flávia Machado; http://lattes.cnpq.br/7634869593114668; Oliveira, Iago Martins; http://lattes.cnpq.br/5607454383736414; Oliveira, Raquel de Souza Lemos de; http://lattes.cnpq.br/2800379800893485Embargada.Item type: Item , Identificação de enterobactérias e Acinetobacter spp. em araras-canindé (Ara ararauna) recebidas no Centro de Triagem de Animais Silvestres de Goiás(Universidade Federal de Goiás, 2025-02-25) Alves, Lisandra Rodrigues; Almeida, Ana Maria de Souza; Ballaminut, Nara; Borsanelli, Ana Carolina; http://lattes.cnpq.br/4344854096706983; Borsanelli, Ana Carolina; Silva, Rodrigo Otávio Silveira; Baldini, Maria Helena MazzoniEmbargoItem type: Item , Transferência Intrafolicular de Ovócitos Imaturos (TIFOI) para maturação in vivo de ovócitos bovinos vitrificados(Universidade Federal de Goiás, 2024-07-30) Chaves, José Eduardo Vieira; Dode, Margot Alves Nunes; http://lattes.cnpq.br/6912403887412900; Melo, Leonardo de França e; http://lattes.cnpq.br/7210044551904428; Sprícigo, José Felipe Warmling; http://lattes.cnpq.br/1634468962324103; Spricigo, Jose Felipe Warmling; Pascottini, Osvaldo Bogado; Lucci, Carolina MadeiraEmbargada.Item type: Item , Reanimação volêmica com solução de cloreto de sódio 0,9% em cadelas com suspeita de piometra e sepse(Universidade Federal de Goiás, 2022-03-07) Faria, Amanda Carvalho; Franco, Leandro Guimarães; Braga, Sandro de Melo; Silva, Marco Augusto Machado; http://lattes.cnpq.br/2134206254307043; Silva, Marco Augusto Machado; Pimenta, Eutálio Luiz Mariani; Botelho, Ana Flávia MachadoFluid therapy is one of the main goals in the treatment of the septic patient, however, particularities of fluid therapy like volume, rate and which solution to use are a challenge due to the pathophysiological changes of sepsis. The objective of this study was to carry out a bibliographic survey about fluid therapy in sepsis in dogs and evaluate clinically and laboratory the volume resuscitation with sodium chloride solution 0,9% in female dogs with pyometra and suspected sepsis. Were included nine female dogs classified by the criteria of systemic inflammatory response syndrome (SIRS) associated with the specific evaluation of organic failure (SOFA) or hyperlactatemia, attended at the Veterinary Hospital of the Veterinary and Zootechnics School of Federal University of Goiás. After diagnosis, the female dogs received a bolus of 15 ml/kg of 0,9% NaCl over 30 minutes, followed by a maintenance rate of 2 ml/kg/h for seven hours. Clinical parameters were evaluated at baseline, after 30 minutes of bolus and every hour, until completing six hours of evaluation. The laboratory tests were performed at the time of diagnosis and after seven hours of fluid therapy. The main clinical findings were reduction in tachycardia, rectal temperature, and dehydration. In the laboratory, there was a reduction in the lactate value, an increase in plasma chlorine and a reduction in red blood cells, hematocrit, hemoglobin and leukocytes. It was concluded that the use of 0.9% NaCl solution reduced the frequency of tachycardia and lactate concentration in animals with pyometra and suspected sepsis, but increased the incidence of hyperchloremia, without promoting metabolic acidosis.Item type: Item , Avaliação radiográfica, macroscópica e determinação da matéria mineral de carcaças de Psittacara leucophthalmus(Universidade Federal de Goiás, 2015-10-09) Alves, Elizama Rodrigues; Miyagui, Eliane Sayuri; Cardoso, Júlio Roquete; Borges, Naida Cristina; Borges, Naida Cristina; Cruz, Viviane Souza; Café, Marcos BarcellosEmbargadoItem type: Item , Avaliação oftalmológica de bovinos hígidos das raças Gir e Nelore(Universidade Federal de Goiás, 2016-07-22) Morais, Tábata Laíza; Lima, Aline Maria Vasconcelos; Martins, Danieli Brolo; Cunha, Paulo Henrique Jorge da; http://lattes.cnpq.br/3363890096623194; Cunha, Paulo Henrique Jorge da; Amaral, Andréia Vitor Couto do; Borges, Naida CristinaConteúdo embargadoItem type: Item , Diagnóstico soroepidemiológico e molecular de Mycoplasma gallisepticum e Mycoplasma synoviae em frangos de corte(Universidade Federal de Goiás, 2011-02-25) Alcântara, Juliana Bonifácio de; Linhares, Guido Fontgalland Coelho; Café, Marcos Barcellos; Andrade, Maria Auxiliadora; Andrade, Maria Auxiliadora; Barbosa, Silvia Minharro; Stringhini, José Henrique-Item type: Item , Avaliação do potencial do peptídeo indolicidina na descontaminação de sêmen bovino(Universidade Federal de Goiás, 2021-03-04) Santos, Gabriel Henrique; Lorenzón, Esteban Nicolás; http://lattes.cnpq.br/5721301206170261; Penido, Paula Maria Pires do Nascimento; http://lattes.cnpq.br/3728828455536727; Souza, Guilherme Rocha Lino de; http://lattes.cnpq.br/1127532567066692; Souza, Guilherme Rocha Lino de; Gambarini, Maria Lucia; Ferreira Júnior, ÁlvaroThe growing interest in artificial insemination in cattle has led researchers to study techniques that make it possible to preserve semen without compromising its ability to fertilize. This project evaluated the antiviral and antibacterial activity of the peptide indolicidin and its potential use as an antiviral agent for a product of high commercial value, which is the semen of selected cattle. Firstly, the antibacterial activity of the indolicidin peptide was evaluated against the bacterium E. coli at the concentrations described in the literature. Based on Escherichia coli, the antibacterial activity of the peptide was evaluated at concentrations of 10 μM, 20 μM and 30 μM against Leptospira interrogans. Subsequently, the peptide was tested at concentrations of 10 μM, 20 μM and 30 μM on cultured cells (MDBK), in which no changes in cell morphology or viability were observed. The antiviral activity of the peptide was then analyzed in MDBK cells artificially infected with bovine alphaherpesvirus type-1 (BoHV-1), in which the peptide was incubated at concentrations of 4 μM, 6 μM, 8 μM, 10 μM, 20 μM and 30 μM, and the safety of the peptide against bovine semen was evaluated according to quality parameters. The indolicidin peptide was safe against semen and cultured cells. In bacteria, the best concentration identified was 30 μM, while in BoHV-1 the best concentration was 8 μM. To date, no methodology has been described for the efficient inactivation of BoHV-1, nor even for minimizing the viral concentration in bovine semen, which makes this project interesting for the commercialization of semen on the national and international markets.Item type: Item , Maus-tratos animais no contexto de violência doméstica na região metropolitana de Goiânia(Universidade Federal de Goiás, 2022-02-03) Soares, Fernanda Bastos; Machado, Ingrid Bueno Atayde; Souza, Tatiana Machiavelli Carmo; http://lattes.cnpq.br/3120018580121934; Jayme, Valéria de Sá; http://lattes.cnpq.br/0603234425928309; Jayme, Valéria de Sá; Modena, Celina Maria; Hellmeister Filho, PauloVeterinary Medicine is one of the professions that integrate the health area. From this assumption, that professionals have the possibility to intervene in situations which cause damage to animal and human health, just as domestic violence and animal abuse. Studies show that individuals who are violent with animals tend to commit violent crimes against people, or people who are violent with others may commit crimes against animals. However, there are few studies within Veterinary Medicine that assess such behaviors and their consequences. This study evaluated the perception of the link between domestic and animal violence, which has a public health character and has closely linked components, as they act as indicators of various social problems, such as domestic violence and social vulnerability. A total of 117 questionnaires were applied, 80 of which were applied to Veterinary Medicine students, 34 to veterinarians and three to women. Data were collected about the crimes of animal abuse and domestic violence, through the Public Security Observatory of the State of Goiás, in which the dynamics between the analyzed crimes was observed, signaling that before the aggression to the human being, the animal is the first victim. It was found that Veterinary Medicine and its professionals are not prepared to combat crimes of animal abuse and, consequently, help to break the cycle of domestic violence, just as the women participating in the research showed that their aggressors have traces of aggression against animalsItem type: Item , Soroprevalência e fatores de risco para infecção por Toxoplasma gondii em ovinos no estado de Goiás(Universidade Federal de Goiás, 2021-01-29) Moura, Catarina Elízia Bernardino Rates de; Jayme, Valéria de Sá; http://lattes.cnpq.br/0603234425928309; Monteiro, Caio Márcio de Oliveira; http://lattes.cnpq.br/2496419306394657; Teixeira, Weslen Fabricio Pires; http://lattes.cnpq.br/1222753642148629; Teixeira, Weslen Fabricio Pires; Felippelli, Gustavo; Pascoal, Lívia MendonçaToxoplasmosis is a zoonosis of wide distribution worldwide, caused by the protozoan Toxoplasma gondii, which can cause economic losses in sheep production mainly due to the appearance of reproductive disorders. In addition, sheep infected with T. gondii may represent a potential risk to human health, due to the large cystogenic capacity that some isolates of the parasite present, leading to the possibility of human infection through the ingestion meat from infected animals. In this sense, the objective of the aforementioned work was to evaluate seroprevalence and risk factors for Toxoplasma gondii infection in sheep in the state of Goiás, located Center-Western region of Brasil. For this purpose, through the indirect immunofluorescence reaction (IFA), 1000 serological samples from sheep from the 18 microregions were analyzed. of State. The data were analyzed using Pearson's chi-square test, which evaluated the possible risk factors for T. gondii (p≤0.05), with the odds ratio (OR) estimates obtained, with a confidence interval of (CI) 95%. The risk factors were calculated considering the risk for each animal, (calculated from the risk), using the software Statistica 10 (StartSot Inc., 2011). In 34.3% (343/1000) of the analyzed samples, the occurrence of anti- T. gondii antibodies (IgG) was observed with serological titers ≥ 64 to ≥ 65536 that varied in the regions from 18.1% (15/83) to 64.15% (34/53). In all regional unitis sampled in the state of Goiás, seroreagent animals were detected, being the age, the water, the form of replacement of the herd and the presence of domestic cats and wild animals, considering the risk factors statistically associated with the serum-occurrence of antibodies against Toxoplasma gondii in sheep.
