DESENVOLVIMENTO DE LINFOMA EM CÃO COM LEISHMANIOSE VISCERAL

Canine lymphoma results in the uncontrolled proliferation of malignant lymphocytes originating from lymphoreticular cells, mainly affecting lymphoid organs such as lymph nodes, liver, bone marrow and spleen. It is considered the most common lymphoproliferative neoplasia, which can be classified according to its anatomical location in the forms: multicentric, alimentary, cutaneous, thymic and extranodal. The objective of this study was to report the clinical aspects of lymphoma in a dog with canine visceral leishmaniasis, as well as to emphasize the importance of complementary tests to obtain an   accurate diagnosis in cases of comorbidities. A 5-year-old male Doberman dog, weighing 30 kg, was attended at the Metropolitan Veterinary Hospital of Caucaia (HVM), presenting with edema in the left anterior limb, hypocorous mucosae, halitosis, dehydration, fever, peeling and skin lesion, onychogrifose, anorexia, subcutaneous nodules and palpable lymph nodes, and the left axillary lymph node was markedly enlarged. According to the anamnesis and physical examination, hematological, biochemical (renal and hepatic reviews) tests, serology for Calazar, chest X-ray and lymph node cytology were requested. The cytology result indicated a neoplastic picture suggestive of lymphoma and the serology was reactive for leishmaniasis. The patient was referred to the oncologist in order to establish the best therapeutic form for the lymphoma, thus giving the appropriate prognosis, but the animal died due to its progressive clinical condition before starting the treatment. It is concluded that the clinical signs together with the complementary exams are important in obtaining the diagnosis for lymphoma and leishmaniasis, assuming that these diseases can affect the animal in isolation or in a joint manner.O linfoma canino resulta na proliferação descontrolada dos linfócitos malignos originados pelas células linforreticulares, acometendo principalmente os órgãos linfóides que são os linfonodos, fígado, medula óssea e baço. É considerado a neoplasia linfoproliferativa mais comum, a qual pode ser classificada de acordo com a sua localização anatômica nas formas: multicêntrico, alimentar, cutâneo, tímico e extranodal. O objetivo desse trabalho foi relatar os aspectos clínicos do linfoma em um cão portador da Leishmaniose visceral canina, bem como ressaltar a importância dos exames complementares para a obtenção de um diagnóstico preciso em casos de co-morbidade. Foi atendido no Hospital Veterinário Metropolitano de Caucaia (HVM), um canino da raça Doberman, macho, 5 anos de idade, pesando 30 quilos, apresentando edemaciação no membro anterior esquerdo, mucosas hipocoradas, halitose, desidratação, febre, descamação e lesão na pele, onicogrifose, anorexia, nódulos subcutâneo e linfonodos palpáveis, sendo que o linfonodo axilar esquerdo estava acentuadamente aumentado. De acordo com a anamnese e exame físico, foram solicitados os exames hematológicos, bioquímicos (análises renal e hepática), sorologia para Calazar, radiografia de tórax e citologia do linfonodo. O resultado da citologia indicou um quadro neoplásico sugestivo de linfoma e a sorologia foi reagente para leishmaniose. O paciente foi encaminhado para o oncologista com o intuito de o especialista instituir a melhor forma terapêutica para o linfoma, dando assim o prognóstico adequado, porém o animal veio a óbito devido sua progressiva condição clínica antes de iniciar o tratamento. Conclui-se que os sinais clínicos juntamente com os exames complementares são importantes na obtenção do diagnóstico para o linfoma e leishmaniose, partindo do princípio que essas enfermidades podem acometer o animal de forma isolada ou conjunta

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

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
