The purpose of this research project was to determine knowledge of the Rhipicephalus microplus tick among seventy cattle ranchers in the Caçapava do Sul and Lavras do Sul municipalities in Rio Grande do Sul State, through completing a structured questionnaire. The replies to the questions on the land areas covered by the properties show that 27%, 26%, 21.5%, 20% and 5.5% cover more than 500 hectares, between 150 and 300 hectares, between 300 and 500 hectares, between 50 and 150 hectares, and under 50 hectares, respectively; 75% of the ranchers are raising more than 100 head of cattle; 84.3% have cultivated grazing pastures and 15.7% have only native grasslands; 87.14% of the ranchers rated bovine babesiosis as the main tick-borne disease, and 76% checked out tick control products recommended by veterinarians. They mentioned 13 formulations and/or associations of tick control products. The tick control biogram test is a new tool for 58.6% of these cattle ranchers. Producers use late control, based on tick control chemicals.

Bovine babesiosis, caused by Babesia bovis and B. bigemina, is a major tick-borne disease of cattle with global economic impact. The disease can be prevented using integrated control measures including attenuated Babesia vaccines, babesicidal drugs, and tick control approaches. Vaccination of cattle with the Rhipicephalus microplus Bm86-based recombinant vaccine reduces the fitness of R. microplus and R. annulatus, but several booster inoculations are required to maintain protection. Herein, we generated a stable transfected strain of B. bovis expressing an enhanced GFP (eGFP) and a chimeric version of Bm86 (B. bovis/Bm86/eGFP). The eGFP was expressed in the parasite cytoplasm, whereas Bm86 was displayed on the surface of merozoites. Three splenectomized calves experimentally infected with B. bovis/Bm86/eGFP showed mild signs of acute disease and developed long-lasting antibody responses to B. bovis and native Bm86. No evidence of sequestration of parasites in the cerebral capillaries was found upon postmortem analysis, confirming attenuation of the strain. This is the first report of transfected B. bovis expressing the tick antigen Bm86 on the merozoite surface that elicits an antibody response to native Bm86. These results represent a proof of concept for a novel live, attenuated, tagged dual-vaccine approach to attempt simultaneous control of babesiosis and tick infestation.

ABSTRACTObjective: to list the main medicinal plants used by ecological farmers from southern Rio Grande do Sul in the supplementary treatment of diabetes mellitus. Method: it was performed a study with qualitative approach of  exploratory and descriptive kind. The study subjects were farmers who sell their products at the ecological fair of Pelotas. Data were collected using semi-structured questionnaire. The interviews were recorded with consent of farmers and the plants were georeferenced and photographed for taxonomic  identification. The project was approved by the Ethics Committee of the Faculty of Medicine at 072/2007 opinion. Results: ten plants were mentioned in the treatment of diabetes mellitus. According to the literature, six of them had positive results in animals or humans as hypoglycemiants, and the other plants are indicated to treat various other symptoms. Conclusion: medicinal plants can act as an adjuvant of the medicamentous therapy in reducing glicemy of the disease carriers, taking into account the legal and safe precepts for using and importance of nurses in advising on the correct use of these therapies.

Abstract Chagas disease (CD) is considered a typical low-income population sickness of the developing countries in Latin America. Given the historical relevance of CD in individuals in southern Rio Grande do Sul (RS) State, Brazil, the aim of this study was to identify the knowledge of the CD and its vectors by cardiac patients, and the prevalence of anti-T cruzi antibodies in these individuals in Pelotas, city located in Rio Grande do Sul (RS) state, Brazil. The subjects with cardiac disease were submitted to a semi-structured questionnaire as well as two serological tests in order to detect anti-T. cruzi IgG antibodies. Of the individuals that born in municipalities showing the highest triatomine infestation rates in recent decades, 81.8% were able to recognize the vector insect (p = 0.0042; OR = 5.9), and 83.3% reported either themselves or someone in their families to have CD (p = 0.043, OR = 5.2). Of the 54 patients submitted to serological analysis, only 01 patient (1.9%) was positive for anti-T. cruzi antibodies, a 55 year old man from the rural area of Canguçu county. This study provides support for the evaluation to be extended to other cardiology centers, given the importance of Chagas disease in Brazil.

The highland grasslands, characteristic of the mountain region of the state of Rio Grande do Sul, have been used historically for several commercial purposes, including extensive livestock, forestry, and agriculture. The biodiversity has a high endemism, but there is a lack of studies on various animal and plant groups. Birds of prey are a great group to assess environmental quality, as they are top predators. This study aimed to test if the diurnal birds of prey community is changing due to the replacement of native grasslands by other human economic activities. We surveyed birds of prey at 12 sampling points from August 2018 to June 2019, including protected grasslands and livestock grasslands, agricultural, and forestry areas. We obtained 1,582 records of birds of prey of 17 species, and the highest richness and number of records, were obtained in the protected grasslands (17 spp.; 393 records) and livestock grasslands (15 spp.; 434 records), followed by agriculture (13 spp.; 418 records) and forestry areas (9 spp.; 337 records). There was a significant difference in the richness of birds of prey in the protected grasslands, livestock grasslands and agriculture areas over the forestry areas. In the number of records, there was a significant difference between livestock grasslands and agriculture areas over forestry areas. This study showed that the conversion of native grassland areas, mainly by forestry, affects the composition of the diurnal birds of prey community, especially the rarest and most endangered species.

Abstract This article presents a research focusing on the meanings of initial training in Youth and Adult Education - EJA (abbreviation in Portuguese), based on the voices of students from the Licentiate Degree Course in Languages at the State University of Rio Grande do Sul. For this purpose, a qualitative bibliographical research was carried out with the application of a semi-structured questionnaire, with a closed and an open part, with free answers. With this, the aim was to understand which meanings of initial training are present in the voices of three undergraduates of the Languages Course who developed activities in EJA. Reflections on the theme were referenced based on studies by Dourado (2009) and Freire (1997, 2002, 2009), among others. As main results, we highlight the learning of these academics from the practices developed, as scholarship holders from PIBID/ CAPES/UERGS, at the Paulo Freire Municipal Culture Center in Porto Alegre and their demands for greater inclusion of EJA approaches in the curriculum of  Languages Course. Keywords: PIBID-EJA; EJA in languages; voices of undergraduate students of languages; EJA in Rio Grande Sul.

Resumo O monitoramento contínuo da qualidade do ar local é extremamente importante para a gestão ambiental de uma cidade, mas nem sempre viável pelo alto custo dos equipamentos. Por conta disso, investe-se muito na utilização da modelagem numérica no estudo da qualidade do ar, que é altamente dependente de inventários de emissões dos poluentes e seus precursores. Nesse contexto o objetivo deste trabalho foi realizar um estudo da dispersão do monóxido de carbono (CO) na Região Metropolitana de Porto Alegre, no estado do Rio Grande do Sul, utilizando o sistema de modelagem numérica CCATT-BRAMS, com ênfase nas fontes veiculares. Foram analisados dois períodos - janeiro de 2009 e janeiro de 2016 - utilizando-se as informações dos inventários de gases precursores elaborados pela FEPAM para os anos base de 2009 e 2013, respectivamente, distribuídos espacialmente com o auxílio do pré-processador de emissões PREP-CHEM-SRC utilizado pelo CCATT-BRAMS. No geral, as simulações representaram coerentemente os dados observados pela rede de monitoramento, com RMSE abaixo de 0,3 na maioria das estações avaliadas. Análises de sensibilidade também revelaram que, para o período avaliado, aproximadamente 40% da concentração de CO sobre a cidade de Porto Alegre foi devido ao transporte de larga escala, proveniente das cidades localizadas ao norte, dentro da Região Metropolitana.
