    Peanut (Arachis hypogaea L.) is an important crop that can fix nitrogen through symbiosis with rhizobia. Rhizobia populations with diverse characteristics than those traditionally described as peanut microsymbionts have been found in tropical soils. With the objective of studying the diversity and phylogeny of these rhizobia, 22 bacterial strains were isolated from nodules of seven peanut varieties grown in Spodosols of Pernambuco State, Brazil. The isolates were examined in culture medium by means of some of their phenotypic characteristics and tested for intrinsic antibiotic resistance (IAR). DNA profiles were determined with the BOX-PCR and compared with 19 reference strains. All isolates showed rapid growth, and most of them acidified the culture medium. In general, high antibiotic resistance was observed to penicillin G, chloramphenicol and tetracycline and susceptibility was observed to neomycin, erythromycin and rifampicin. The analysis of their phenotypic characteristics, that is, colony morphology and IAR, provided little information about the phylogeny of the isolates. However, using compilation of phenotypic and molecular characteristics, we were able to observe a great diversity of these rhizobia and to reveal the presence of new species.Keywords: Antibiotic resistance, Arachis hypogaea L., BOX-PCR, colony morphology, diversityAfrican Journal of Biotechnology Vol. 12(17), pp. 2147-215

    As the use of pesticides and agricultural practices became inseparable, human populations became vulnerable to contamination by these substances. The objective is to demonstrate the main problems that pesticides can cause to human health, based on what is exposed in the literature. This is an integrative literature review study, which used the BVS, LILACS and Medline as the search database. 107 articles were found, therefore only 23 were selected. These studies were published between the years 2018 and 2023. Important contributions mainly related to human and environmental conditions, especially dealing with the danger of pesticides that enter homes and reach the table spontaneously and can cause great damage. Another aspect that deserves research is how to reduce the use of foods that contain excess pesticides and how they are being sanitized and ingested.A medida que el uso de pesticidas y las prácticas agrícolas se volvieron inseparables, las poblaciones humanas se volvieron vulnerables a la contaminación por estas sustancias.

    Post-traumatic stress disorder (PTSD) is an anxiety disorder that manifests itself as a result of an individual experiencing violent acts or traumatic situations. The objective is to describe post-traumatic stress in military police and the health problems resulting from this cause. An integrative literature review of an exploratory-descriptive nature with a qualitative approach was carried out. The damage caused by PTSD to an individual's life is evident. Cognitive-behavioral therapy has several managements that help to minimize the symptoms, with the reinsertion of the social identity and the confrontation of the disorder. as well as making the population and police institutions aware of the difficulties and problems faced by these workers.O transtorno de estresse pós-traumático (TEPT) é um distúrbio de ansiedade que se manifesta em decorrência do indivíduo ter sofrido experiências de atos violentos ou de situações traumáticas. O objetivo é descrever o estresse pós-traumático em policiais militares e os problemas de saúde resultante dessa causa. Foi realizada uma revisão integrativa da literatura de caráter exploratório-descritivo com uma abordagem qualitativa. Fica evidente os prejuízos do TEPT para a vida do indivíduo. A terapia cognitivo-comportamental dispõe de vários manejos que ajudam a minimizar os sintomas, com reinserção da identidade social e o enfrentamento do transtorno é de fundamental importância a necessidade de procurar a diminuição das cargas psíquicas negativas relacionadas ao ambiente de trabalho do profissional policial militar, bem como conscientizar a população e instituições policiais sobre as dificuldades e problemas enfrentados por esses trabalhadores

    Hepatitis E infection is found worldwide and is common in low- and middle-income countries with limited access to essential water, sanitation, hygiene and health services. In these areas, the disease occurs in both outbreaks and sporadic cases. Outbreaks often follow periods of fecal contamination of drinking water supplies and can affect thousands of people. This article aims to raise awareness among the population about the risks of hepatitis E and mainly to highlight the correlation with water. This is an integrative review of the literature. Within the time window of the last five years. The results confirm the importance of drinking water and basic sanitation, as well as highlighting the lack of studies in this area. Therefore it is necessary to talk more about hepatitis E, this article has the legacy of being the basis for other reviews, highlighting that prevention is the most effective approach against infection, however it is necessary to maintain quality standards for public water supply and establish adequate human feces disposal systems, as well as personal hygiene care.A infecção por hepatite E é encontrada em todo o mundo e é comum em países de baixo e médio rendimento com acesso limitado a serviços essenciais de água, saneamento, higiene e saúde. Nessas áreas, a doença ocorre tanto em surtos quanto em casos esporádicos. Os surtos geralmente seguem-se a períodos de contaminação fecal do abastecimento de água potável e podem afetar milhares de pessoas. Esse artigo tem como objetivo conscientizar a população sobre os riscos da hepatite E e principalmente destacar a correlação com a água. Trata-se de uma revisão integrativa da literatura. Dentro da janela temporal dos últimos cinco anos. Os resultados confirmam a importância da água potável e saneamento básico, bem como evidenciam a falta de estudos nessa área. Por tanto é necessário falar mais sobre a hepatite E, esse artigo fica com o legado de ser base para outras revisões, ressaltando que a prevenção é a abordagem mais eficaz contra a infecção, entretanto é necessário manter padrões de qualidade para o abastecimento público de água e estabelecer sistemas adequados de eliminação de fezes humanas, bem como os cuidados de higiene pessoal

    Brazilian Flora 2020: Leveraging the power of a collaborative scientific network

    No full text
    International audienceThe shortage of reliable primary taxonomic data limits the description of biological taxa and the understanding of biodiversity patterns and processes, complicating biogeographical, ecological, and evolutionary studies. This deficit creates a significant taxonomic impediment to biodiversity research and conservation planning. The taxonomic impediment and the biodiversity crisis are widely recognized, highlighting the urgent need for reliable taxonomic data. Over the past decade, numerous countries worldwide have devoted considerable effort to Target 1 of the Global Strategy for Plant Conservation (GSPC), which called for the preparation of a working list of all known plant species by 2010 and an online world Flora by 2020. Brazil is a megadiverse country, home to more of the world's known plant species than any other country. Despite that, Flora Brasiliensis, concluded in 1906, was the last comprehensive treatment of the Brazilian flora. The lack of accurate estimates of the number of species of algae, fungi, and plants occurring in Brazil contributes to the prevailing taxonomic impediment and delays progress towards the GSPC targets. Over the past 12 years, a legion of taxonomists motivated to meet Target 1 of the GSPC, worked together to gather and integrate knowledge on the algal, plant, and fungal diversity of Brazil. Overall, a team of about 980 taxonomists joined efforts in a highly collaborative project that used cybertaxonomy to prepare an updated Flora of Brazil, showing the power of scientific collaboration to reach ambitious goals. This paper presents an overview of the Brazilian Flora 2020 and provides taxonomic and spatial updates on the algae, fungi, and plants found in one of the world's most biodiverse countries. We further identify collection gaps and summarize future goals that extend beyond 2020. Our results show that Brazil is home to 46,975 native species of algae, fungi, and plants, of which 19,669 are endemic to the country. The data compiled to date suggests that the Atlantic Rainforest might be the most diverse Brazilian domain for all plant groups except gymnosperms, which are most diverse in the Amazon. However, scientific knowledge of Brazilian diversity is still unequally distributed, with the Atlantic Rainforest and the Cerrado being the most intensively sampled and studied biomes in the country. In times of “scientific reductionism”, with botanical and mycological sciences suffering pervasive depreciation in recent decades, the first online Flora of Brazil 2020 significantly enhanced the quality and quantity of taxonomic data available for algae, fungi, and plants from Brazil. This project also made all the information freely available online, providing a firm foundation for future research and for the management, conservation, and sustainable use of the Brazilian funga and flora

    Abstract An updated inventory of Brazilian seed plants is presented and offers important insights into the country's biodiversity. This work started in 2010, with the publication of the Plants and Fungi Catalogue, and has been updated since by more than 430 specialists working online. Brazil is home to 32,086 native Angiosperms and 23 native Gymnosperms, showing an increase of 3% in its species richness in relation to 2010. The Amazon Rainforest is the richest Brazilian biome for Gymnosperms, while the Atlantic Rainforest is the richest one for Angiosperms. There was a considerable increment in the number of species and endemism rates for biomes, except for the Amazon that showed a decrease of 2.5% of recorded endemics. However, well over half of Brazillian seed plant species (57.4%) is endemic to this territory. The proportion of life-forms varies among different biomes: trees are more expressive in the Amazon and Atlantic Rainforest biomes while herbs predominate in the Pampa, and lianas are more expressive in the Amazon, Atlantic Rainforest, and Pantanal. This compilation serves not only to quantify Brazilian biodiversity, but also to highlight areas where there information is lacking and to provide a framework for the challenge faced in conserving Brazil's unique and diverse flora
