Root and stem rot are diseases that compromise the crop, causing major losses, due to direct losses in production and the spread of pathogens, respectively. Studies have revealed the occurrence of a diversity of phytopathogenic fungi, standing out those of the Botryosphaeriaceae family, associated with stem rot. This work aimed to identify fungal diversity with emphasis on the Botryosphaeriaceae family, associated with cassava seed stems, after disinfection and induction of rot. Fungal isolations were carried out by serial dilution, of the rotten cuttings from Alenquer, Belterra, Curuá, Faro, Itaituba, Juruti, Mojuí dos Campos, Prainha and Santarém municipalities, followed by DNA extraction using the Wizard® Genomic DNA Purification kit. (Promega). To study diversity, identification was carried out by amplification of the ITS region with the universal primers ITS1 and ITS4 and subsequent sending for sequencing, using the Sanger method. The electropherograms were trimmed and edited so that the contigs could be used for identification. Molecular identification was initiated by using Blast and subsequent comparison with standard sequences of the species of the associated genus/section/complex. Phylogenetic analysis of species from the Botryosphaeriaceae family was carried out in the gene regions of the translation elongation factor (TEF 1 – α), RNA polymerase subunit II (rpb2) and internal transcribed spacer (ITS). Eleven genera were identified in the fungal diversity in cassava cuttings (Lasiodiplodia, Neoscytalidium, Fusarium, Penicillium, Aspergillus, Cladosporium, Hyphopichia, Trichoderma, Clonostachys, Diaporthe and Phomopsis). The genus Lasiodiplodia was the most frequent, with at least the species Lasiodiplodia theobromae, L. brasiliensis, L. euphorbiaceicola and L. pseudotheobromae detected, in addition to the species Neoscytalidium dimiditum, distributed differentially among the different communities and municipalities in the western region of Pará, and all isolates of Lasiodiplodia and Neoscytalidium were capable of causing lesions in cassava roots and were reisolated, confirming its pathogenicity. These data demonstrate the importance of healthy propagation material, as pathogens can be disseminated even when asymptomatic and with superficial disinfection treatments.Item type:Item, Fatores de risco associados à prevalência de anticorpos contra brucelose em equídeos do Oeste do Pará, Brasil(Universidade Federal do Oeste do Pará, 2024-04-30) PICANÇO, Eloine Maria Bandeira; MINERVINO, Antonio Humberto Hamad; http://lattes.cnpq.br/8597370080049662; http://lattes.cnpq.br/1074630714302965; MINERVINO, Antonio Humberto Hamad; http://lattes.cnpq.br/8597370080049662; NEVES, Kedson Alessandri Lobo; https://orcid.org/0000-0001-6784-5380; http://lattes.cnpq.br/1081832412313971; CLAUDIANO, Gustavo da Silva; https://orcid.org/0000-0002-5063-9123; http://lattes.cnpq.br/6500363801545710; ALBUQUERQUE, Fábio Edir Amaral; http://lattes.cnpq.br/2671420774008662The state of Pará has one of the largest equine populations in Brazil, with more than 800,000 head. Most of these animals are found on farms (farm horses) with livestock farming and are used in the management of cattle and buffaloes. Furthermore, in urban areas of the state, horses are commonly used as a means of transport for transporting materials (cart horse) and in sports such as vaquejada, archery and barrel competitions and horseback riding (sport horse). Infectious diseases cause concern for equine breeders due to the damage to the animals' health, economic and public health impacts in the case of zoonoses. In this context, equine brucellosis stands out, a chronic, infectious, zoonotic disease caused by bacteria of the genus Brucella sp., especially in areas where bovine brucellosis is endemic. The disease requires mandatory notification to the Official Veterinary Service of Brazil when there is any suspected case according to the World Organization for Animal Health (WHO). Considering the significant equine herds and the lack of epidemiological studies in Pará, especially in the western region of the state, the objective was to determine the prevalence of antibodies against Brucellosis in horses raised in western Pará and identify possible risk factors associated with this disease in three diverse groups: farm, sport and cart horses. From a preliminary cross-sectional study with sampling at two levels per cluster for farm horses that included 75 properties in 14 municipalities and with convenience sampling to collect carriage and sport horses, a total of 1,059 equids were included in the study, being 1039 horses, 13 donkeys and 7 mules. Serum samples were obtained via jugular venipuncture using a sterile vacuum system with tubes without anticoagulant. The blood was centrifuged at 2000 x g for 10 min, and the serum was aliquoted and stored at -35°C for analysis. During sample collection, an epidemiological questionnaire was used to obtain information about animal characteristics, management and local conditions that may act as risk factors for the seroprevalence of the disease. To detect antibodies against equine brucellosis, the Buffered Acidified Antigen test (AAT) and Seroagglutination in Tubes with 2-mercaptoethanol (2-ME) were used as screening to confirm the results. Serological analyzes were carried out at the Animal Health Laboratory (LARSANA) of the Federal University of Western Pará. The data were tabulated to determine the frequency of seropositive and seronegative horses and the prevalence. Univariate analysis was performed using the Chi-square test to investigate the association between the prevalence of antibodies and possible risk factors associated with the diseases. A logit-type binary logistic regression with Backward elimination of terms including the risk factors considered. Variables with P<0.05 were maintained in the final model. The data were analyzed using Minitab 17 software. And the 95% confidence interval was calculated using Prism software. Of the 1,059 animals sampled, 44 (4.05% - 95% CI: 3-5.5) tested positive in the AAT test. Positive samples in the AAT test were confirmed using the 2-ME test and of these 11 animals were positive, 15 inconclusive and 18 negative. Considering only the results confirmed by 2-ME, the prevalence of equine brucellosis at animal level in horses in the western region of Pará was 1.03% (95% CI: 0.5-1.8). Among the factors considered, only the Southwest Mesoregion of Pará (P = 0.047) interfered with the prevalence of anti-Brucella sp antibodies. The presence of Brucellosis-positive animals was not associated with reproductive problems reported by animal owners. This is the first report of equids seropositive for Brucellosis in the region, which contributes to the knowledge of the epidemiology of the disease and confirms the potential risk of the equine species to public health since they are in direct contact with humans and other animals.Item type:Item, Atividades contextualizadas de matemática para o ensino de jovens e adultos(Universidade Federal do Oeste do Pará, 2022) MACHADO, Antônio Ítalo de Jesus; SANTOS, Lilian Cristiane Almeida dos; https://orcid.org/0000-0002-2871-7631; http://lattes.cnpq.br/7382782107751169; http://lattes.cnpq.br/7129240071319967This research aimed to investigate whether contextualized activities containing fundamental operations facilitate and/or contribute to the understanding of students enrolled in the EJA modality. Specifically, it sought to elaborate and apply exercises that can show and work with local reality and identify whether the use of everyday life will facilitate the understanding of mathematics in the classroom. The methodology of the research was a qualitative one, where bibliographic research was carried out with the help of books, articles and the Internet, where information on the theme was collected and data was collected through observations and the application of questionnaires composed of open questions and a field diary for taking notes of the observations. The target audience of the research were students enrolled in the EJA modality in four schools of the public school system of Santarem-PA. After data collection, a descriptive analysis was carried out. The contextualized questions were well received by the students and supervising teachers. In general, the students knew how to solve the questions mentally, but had difficulty in writing the correct result of the analyzed questions. After the application of the contextualized activities and the analysis of the results, we conclude that mathematical reasoning is present in many activities that man performs daily and accompanies him within society, for without it we cannot propose a development of critical character and that using everyday life that matches the local reality in math classes helps in the participation and evolution in the student's learning.Item type:Item, O Tangram como recurso metodológico para ensino de álgebra: reflexões acerca da experiência vivenciada na EJA(Universidade Federal do Oeste do Pará, 2021) OLIVEIRA, Francisco Vilson Ferreira de; Hamilton Cunha de Carvalho; http://lattes.cnpq.br/1744251734923415; SANTOS, Rudinei Alves dos; https://orcid.org/0000-0001-6214-3726; http://lattes.cnpq.br/9365709399373081; RODRIGUES, Aroldo Eduardo Athias; http://lattes.cnpq.br/5676701244367080This research addresses the use of Tangram for teaching Mathematics in EJA classes - Youth and Adult Education, from the perspective of a viable resource to teach Mathematics in the classroom, as it is a material with the idea of simple adaptation content and objectives, in addition to arousing students' interest, curiosity and reasoning.
