ABSTRACT: Leptospirosis is a zoonosis that can infect buffaloes and other mammalians, and it’s caused by Gram-negative bacteria of the genus Leptospira spp. The infection occurs through contact with urine or a contaminated environment with the mucous membranes of the animals, and the disease has two phases: leptospiremia and leptospiruria. The objective of this study was to determine the frequency of leptospirosis in buffaloes in the state of Paraná, Brazil, as well as the main serovars present in this area. A total of 276 blood samples were collected from buffaloes from 18 properties located in different cities and mesoregions of Paraná state. A microscopic agglutination test (MAT) was performed to detect the presence of anti-Leptospira spp. antibodies and to identify its serovars. The prevalence was 77.17% (213/276) of buffaloes seropositive for at least one serovar. The most frequent serovar was Icterohaemorrhagiae, followed by the Pomona serovar and serovar Hardjo. This study seems to be the first to determine the frequency of buffaloes with leptospirosis in the state of Paraná. Prevention and control measures are important to control the disease in herds.
RESUMO: Leptospirose é uma zoonose que infecta búfalos e outros mamíferos e é causada por bactérias Gram-negativas do gênero Leptospira spp. A infecção ocorre por meio do contato com a urina ou ambiente contaminado com as membranas mucosas dos animais e a doença possui duas fases: leptospiremia e leptospirúria. O objetivo deste trabalho foi determinar a frequência da leptospirose em bubalinos provenientes do estado do Paraná, assim como determinar os principais sorovares presentes no estado. Um total de 276 amostras de sangue foram coletados de búfalos provenientes de 18 propriedades localizadas em 14 municípios de diferentes mesorregiões do estado do Paraná. O teste de soroaglutinação microscópica (SAM) foi realizado para detecção da presença de anticorpos anti-Leptospira spp. e identificação dos respectivos sorovares. A prevalência de búfalos soropositivos para ao menos um sorovar foi de 77,17% (213/276). O sorovar mais frequente identificado nestes búfalos foi o Icterohaemorrhagiae, seguido pelos sorovares Pomona e Hardjo. Este é o primeiro estudo a determinar a frequência de búfalos com leptospirose no estado do Paraná. Medidas de controle e prevenção são importantes para o controle do agente nos rebanhos.

ABSTRACT. The objectives were to evaluate the biodiversity of bees, forage behavior and their effect on fruit production in the gherkin crop (Cucumis anguria L.) in the campus of the University Center Moura Lacerda in two years. The frequency and type of collection of the insects in the flowers was observed by counting from 8:00 a.m. to 5:00 p.m., in the first 10 minutes of each time, for three distinct days in each year. The percentage of fruiting was quantified in 25 female flowers covered with nylon compared to the 25 female flowers uncovered in the two years. The flowers were visited by the Africanized honey bees Apis mellifera and the native bees Plebeia sp., Exomalopsis sp. and Melissodes sp., and the Africanized honey bees presented higher frequency and constancy with a higher number of visits in the male flowers compared to the female ones and these visits occurred between 8:00 a.m. and 3:00 p.m. Without the visitation of the bees there was no fruit production, and both the Africanized honey bee and the native ones when collecting nectar and pollen, visited both female and male flowers, carrying pollen in their body, being considered important pollinators of this culture.

RESUMO: O objetivo deste trabalho foi identificar as doenças neurológicas que acometeram bovinos no estado do Paraná entre os anos de 2009 e 2015. A investigação aconteceu, preferencialmente, nas propriedades rurais onde os casos ocorreram. Foram registradas as informações sobre a evolução das doenças nos bovinos afetados do rebanho, e os prováveis fatores de risco foram identificados. Todos os procedimentos de exame físico geral e neurológico foram realizados sistematicamente para a caracterização da síndrome neurológica presente. Amostras de sangue e de líquor foram colhidas para a realização de exames laboratoriais. De acordo com o tempo de evolução e com a gravidade dos sinais clínicos observados, os bovinos doentes eram mantidos vivos para acompanhamento da evolução ou da resposta ao tratamento, ou eram submetidos à eutanásia seguida de necropsia. Fragmentos do sistema nervoso e dos demais órgãos foram colhidos para exame histopatológico. O exame de imunofluorescência direta e a prova biológica em camundongos foram realizados em todos os bovinos que morreram, com a finalidade de confirmar ou descartar o diagnóstico de raiva. Métodos laboratoriais específicos das rotinas de virologia, bacteriologia e toxicologia foram empregados, como complementares, para o estabelecimento do diagnóstico diferencial. Foram investigados 236 bovinos com doença neurológica, sendo 85 casos de ocorrência individual e 151 casos distribuídos por surtos que ocorreram em 79 rebanhos. As encefalopatias (180/236; 76,2%) predominaram sobre as mielopatias (27/236; 11,4%). As doenças inflamatórias determinadas por infecções (98/236; 41,5%) e as doenças tóxicas (91/236; 38,6%) foram as principais, enquanto as causas degenerativas (10/236; 4,2%), metabólicas (9/236; 3,8%), físicas (9/236; 3,8%), neoplásicas (4/236; 1,7%), e os defeitos congênitos (1/236; 0,4%) ocorreram menos frequentemente. Os casos inconclusivos somaram 5,9% (14/236). A meningoencefalite por BoHV-5 e a raiva foram as doenças de frequência maior e podem ser consideradas as mais importantes. Dentre as causas tóxicas, as intoxicações por plantas se destacaram (63/91; 69,2%) e foram responsáveis por 26,6% de todos os casos. Destacaram-se ainda a polioencefalomalácia, a meningoencefalite trombótica por Histophilus somni e o botulismo. Essas informações contribuem para que os médicos veterinários adotem condutas mais efetivas de diagnóstico e de prevenção, e são valiosas para o sistema oficial de vigilância epidemiológica do estado.
ABSTRACT: The aim of this study was to identify the neurological diseases that affected cattle in Paraná state between the years 2009 and 2015. The investigation took place, preferably, in the farms where cases occurred. Information on the evolution of the diseases in the affected cattle of the herd was recorded, and the probable risk factors were identified. All general and neurological examination procedures were performed systematically for the characterization of the neurological syndrome in each case. Samples of blood and CSF for laboratory exams were also collected. According to the evolution features and the severity of the observed clinical signs, the diseased cattle were kept alive to follow the progress of the disease, or were submitted to euthanasia followed by necropsy. Fragments of tissues from nervous system and other organs were collected for histopathological examination. Direct immunofluorescence test and biological test were performed on all the cattle that died, in order to confirm or rule out the diagnosis of rabies. Specific virology, bacteriology and toxicology laboratory methods were used as complementary exams in order to establish differential diagnosis. A total of 236 cattle with neurological disease were investigated, 85 cases of individual occurrence and 151 cases distributed by outbreaks that occurred in 79 herds. Encephalopathies (180/236, 76.2%) predominated over mielopathies (27/236, 11.4%). Inflammatory diseases caused by infections (98/236, 41.5%) and the toxic diseases (91/236, 38.6%) were the main causes, while degenerative (10/236, 4.2%), metabolic (9/236; 3.8%), physical (9/236, 3.8%), neoplastic (4/236, 1.7%), and congenital defects (1/236, 0.4%) occurred less often. The inconclusive cases were 5.9% (14/236). BoHV-5 meningoencephalitis and rabies were diseases of higher frequency and may be considered the most important. Among the toxic causes, plant poisonings were highlighted (63/91, 69.2%) and were responsible for 26.6% of all cases. Polioencephalomalacia, thrombotic meningoencephalitis caused by Histophilus somni and botulism were also highlighted. This information helps veterinarians to adopt more effective diagnostic and preventive approaches and is valuable to the state’s official epidemiological surveillance system.

Resumo Um levantamento atualizado das plantas com sementes e análises relevantes acerca desta biodiversidade são apresentados. Este trabalho se iniciou em 2010 com a publicação do Catálogo de Plantas e Fungos e, desde então vem sendo atualizado por mais de 430 especialistas trabalhando online. O Brasil abriga atualmente 32.086 espécies nativas de Angiospermas e 23 espécies nativas de Gimnospermas e estes novos dados mostram um aumento de 3% da riqueza em relação a 2010. A Amazônia é o Domínio Fitogeográfico com o maior número de espécies de Gimnospermas, enquanto que a Floresta Atlântica possui a maior riqueza de Angiospermas. Houve um crescimento considerável no número de espécies e nas taxas de endemismo para a maioria dos Domínios (Caatinga, Cerrado, Floresta Atlântica, Pampa e Pantanal), com exceção da Amazônia que apresentou uma diminuição de 2,5% de endemicidade. Entretanto, a maior parte das plantas com sementes que ocorrem no Brasil (57,4%) é endêmica deste território. A proporção de formas de vida varia de acordo com os diferentes Domínios: árvores são mais expressivas na Amazônia e Floresta Atlântica do que nos outros biomas, ervas são dominantes no Pampa e as lianas apresentam riqueza expressiva na Amazônia, Floresta Atlântica e Pantanal. Este trabalho não só quantifica a biodiversidade brasileira, mas também indica as lacunas de conhecimento e o desafio a ser enfrentado para a conservação desta 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.

OBJECTIVE: The aim of this study was to measure dynamic lung hyperinflation and its influence on dyspnea perception in moderate and severe chronic obstructive pulmonary disease patients after performing activities of daily living. METHODS: We measured inspiratory capacity, sensation of dyspnea, peripheral oxygen saturation, heart rate and respiratory rate in 19 chronic obstructive pulmonary disease patients. These measurements were taken at rest and after performing activities of daily living (e.g., going up and down a set of stairs, going up and down a ramp and sweeping and mopping a room). RESULT: The inspiratory capacity of patients at rest was significantly decreased compared to the capacity of patients after performing activities. The change in inspiratory capacity was -0.67 L after going up and down a ramp, -0.46 L after sweeping and mopping a room, and -0.55 L after climbing up and down a set of stairs. Dyspnea perception increased significantly between rest, sweeping and mopping, and going up and down a set of stairs. Dyspnea perception correlated positively with inspiratory capacity variation (r = 0.85) and respiratory rate (r = 0.37) and negatively with peripheral oxygen saturation (r = -0.28). CONCLUSION: Chronic obstructive pulmonary disease patients exhibited reductions in inspiratory capacity and increases in dyspnea perception during commonly performed activities of daily living, which may limit physical performance in these patients.
