O objetivo deste trabalho foi determinar os teores de colesterol e lipídios totais na porção comestível (tecido muscular) de seis espécies de peixes capturados na região pantaneira do Estado de Mato Grosso do Sul. As espécies estudadas foram o pacu ( Piaractus mesopotamicus), a piranha ( Pygocentrus nattereri), o dourado ( Salminus maxillosus), a piraputanga ( Brycon orbigynanus), o piauçu ( Leporinus macrocephalus) e o pintado ( Pseudoplatystoma coruscans). Usou-se o método colorimétrico de BOHAC et al. para determinação do colesterol e o da extração com solvente orgânico e gravimetria para lipídios totais. Quanto aos teores de lipídios totais, os valores médios obtidos para as seis espécies de peixes estudadas enquadraram-se na faixa de 1,0 a 6,7 g/100 g de tecido muscular dos peixes, sendo a menor concentração apresentada pelo pintado e a maior pela piraputanga. A concentração de colesterol, em mg/100 g de tecido muscular (base úmida), foi mais alta para o dourado (107,4 mg/100 g) e mais baixa para o pintado (51,5 mg/100 g). CHOLESTEROL LEVELS AND TOTAL LIPIDS IN SIX SPECIES OF FISH CAPTURED IN “PANTANAL” REGION OF MATO GROSSO DO SUL STATE Abstract The objective of this work was to determine the cholesterol and total lipids content in the edible portion (muscular tissue) of six species of fish, captured in the “Pantanal region of Mato Grosso do Sul State (Brazil). The studied species were the pacu ( Piaractus mesopotamicus), the piranha (Pygocentrus nattereri), the dourado ( Salminus maxillosus), the piraputanga ( Brycon orbigynanus), the piauçu ( Leporinus macrocephalus) and the pintado ( Pseudoplatystoma coruscans). The method for determination of cholesterol was the colorimetric of BOHAC et al. and for the total lipids was the extraction method with organic solvent and gravimetry. With relationship to the values of total lipids, the average content obtained for the six species of studied fish were in the range of 1,0 to 6,7 g/100 g of muscular tissue of the fish, and the pintado presented smaller concentration and the piraputanga was revealed as the largest lipid source. The cholesterol concentration, in mg/100 g of muscular tissue (raw base) was higher for the dourado (107,4 mg/100 g) and lower for the pintado (51,5 mg/100 g).

Resumo O objetivo desta pesquisa foi estudar o conhecimento ecológico tradicional (CET) relacionado à pesca feita por grupo étnico autoidentificado como quilombola, por meio da análise de fatores que influenciam o consenso cultural e as técnicas da pesca artesanal. Participaram 24 homens e sete mulheres dos quilombos Retiro, Boqueirão, Casalvasco e Manga. Os métodos de amostragem utilizados foram: bola de neve, lista livre e observação participante. Os resultados incluem 47 etnoespécies (46 peixes e um réptil). O consenso cultural é composto por: Hoplias malabaricus, Cichla sp., Pseudoplatystoma fasciatum, Astronotus ocellatus, Satanoperca pappaterra, Brycon cephalus, Piaractus mesopotamicus, P. corruscans, Pimelodus sp., Colossoma macropomum, Pygocentrus nattereri, Mylossoma aureum, Astyanax sp. e Leporinus freiderici. Embora tenha sido maior a riqueza do conhecimento entre pessoas que residiram temporariamente em outros estados brasileiros, este aspecto não esteve relacionado à idade dos entrevistados. A manutenção e a transmissão de CET é propiciada por contato diário com peixes e com o rio desde criança, bem como por observação das práticas de pesca em grupo. O CET é parte da identidade e representa uma herança cultural que deve ser valorizada. É necessária a participação desses atores sociais nos planos de decisão e de gerenciamento de áreas protegidas.

Introduction: The indiscriminate use of antimicrobials has selected for the emergence of resistant strains. Many mechanisms contribute to the spread of antimicrobial-resistant genes, and integrons play a key role in this process. The aim of this study was to describe the serotypes and resistance profiles, and to characterize the presence of integrons in Salmonella strains isolated from Dourados, Mato Grosso do Sul, Brazil. Methodology: Thirty-six isolates from different sources were used. To evaluate the resistance profiles, the determination of minimum inhibitory concentrations together with polymerase chain reaction were used to screen for the presence of class 1 and class 2 integrons. Results: The Infantis serotype of Salmonella was the most frequently isolated serotype. Minimum inhibitory concentrations showed that out of the 36 isolates, 11 (30.5%) were resistant to all the antimicrobials tested. These resistant isolates were separated into three groups: 4 clinical isolates (36.4%), 3 food isolates (36.4%), and 4 water isolates (27.2%). Class 1 integrons occurred in 31 (86.1%) isolates and were found in all 11 resistant isolates (35.5 %) and in 20 (64.5%) of the non-resistant isolates. Class 2 integrons were found in 3 (8.3%) isolates, which were all non-resistant. Conclusion: The presence of an integron did not necessarily confer resistance. Future studies will seek to identify the mechanism behind integron-mediated antimicrobial resistance.

A histological analysis was conducted on the gills of 15 Piaractus mesopotamicus and 19 Prochilodus lineatus specimens collected between April and November 2004 from the Aquidauana River, State of Mato Grosso do Sul, Central-West Brazil, to describe the anatomopathological characteristics of the gills of these freshwater fish. Gill samples were fixated in 10% buffered formalin and processed following histological routine procedures. The histological examination of the gills of P. mesopotamicus revealed intralamellar monogenean and mixosporean cysts of Henneguya piaractus at several developmental stages over the entire (basal, median and distal) lamella. Intraepithelial cysts caused lamella dilation and deformity of adjacent lamellae. In P. lineatus gills, monogenean cysts were detected. In both host species, hyperplasia of the gill epithelium and structural disorganization of secondary lamellae was seen diffusely in the gills, leading to fused lamellae in the gills. In few cases, there was found mononuclear inflammatory cells and hemorrhagic focal points distally in the lamellae.

Abstract The Brazilian Cerrado has several botanical species for medicinal purposes used by traditional communities and many of these plants are not included in the list of Medicinal Plants Research Program of Central Medicines. The purpose of this study was the phytochemical screening and toxicology bioassay front of Brine shrimp L. of ethanolic extracts of eight species of plants used in folk medicine of Campo Grande, Mato Grosso do Sul, Brazil. The ethanolic extracts were submitted to phytochemical screening, determination of phenolic compounds and flavonoids. Toxicological assays were carried front of Brine shrimp according to standard methodology. The analysis TLC and HPLC-DAD confirmed the predominance of phenolic compounds and derivatives, specifically for the quercetin. The most toxic was the C. affinis DC. with death at all concentrations, the A. humile A. St. Hil. showed no mortality and the other species showed intermediate toxicity. The extracts of the investigated species are rich in phenolic compounds and derivatives, specifically quercetin, and feature toxicity between moderate to high, a fact that requires attention, since much of the traditional communities rely on herbal drugs in its raw form with preventive and curative purpose, meeting the basic health care.

The Pacu Piaractus mesopotamicus is the most captured fish species in the Pantanal, Mato Grosso do Sul State, and since 1994, its maximum sustainable yield had already been exceeded. Its capture is carried out only by hooks, as mesh gears are forbidden either for professional or for recreational fishing. The aim of this study was to determine selectivity for different hook sizes used in P. mesopotamicus fishing and to verify which sizes capture only adults. Data were collected in the rivers Miranda, Aquidauana, and Vermelho, in January, March, and April 2002. Six longlines with eight hook sizes were used and we adopted the hook opening as a measure related to selectivity. Different hooks captured individuals of the same length and their medians were similar, evidencing the great overlap among sizes. Regression results showed no significant relationship between ln[c2 (l)/c1 (l)] and total length of captured individuals. In addition, the Kolmogorov-Smirnov test also did not detect significant differences in the size of captured fish. Several hypotheses, such as the selectivity models, shape of selection curves, scarcity of large fishes, and behavior are used in order to explain the absence of hook selectivity for this species. Size of recruitment for this gear was 28 cm of total length, when individuals are still immature.

In this study the structure and diversity of the endohelminth community, as well as its interactions with 73 specimens of Piaractus mesopotamicus are described. The fish were caught in Aquidauana and Miranda rivers, both located in the Pantantal region, in the state of Mato Grosso do Sul. A total of 608,788 specimens of helminthes were found, representing five species: Dadaytrema oxycephala, Chabaudinema americanum, Spectatus spectatus, Rondonia rondoni and Echinorhynchus jucundum. D. oxycephala was more prevalent (91.78%) followed by R. rondoni (73.97%). Simpson's index indicated dominance in the endohelminth infracommunities (C = 0.396) and D. oxycephala was considered central species. A total of 54 hosts had between 2 and 3 species of helminthes. The pairs of the species R. rondoni/D. oxycephala and S. spectatus/D. oxycephala showed significant positive correlation between abundances. There was a significant positive correlation between total length and abundance of S. spectatus (rs = -0.2467 and p = 0.0353). Abundance of R. rondoni between the periods of 1/2003 and 2/2003 (p = 0.0356) and 1/2003 and 4/2004 (p = 0.0009) was significantly different. There was significant prevalence of E. jucundum in the female hosts.

Morcegos frugívoros contribuem para o estabelecimento de muitas espécies de plantas pioneiras através da dispersão de sementes, o que auxilia nos mecanismos de regeneração e sucessão secundária em áreas tropicais. Devido a esta relação entre os morcegos e a flora, torna-se necessário apresentar informações sobre frutos quiropterocóricos, tais como análises nutricionais destes frutos que compõe a dieta dos morcegos. Este estudo teve como objetivo a análise nutricional de frutos consumidos por morcegos no Pantanal da Nhecolândia. As análises visaram avaliar o teor de proteínas, carboidratos totais e redutores destas espécies quiropterocóricas. Verificou-se a partir das análises realizadas que existe grande variação intraespecífica, interespecífica e sazonal, sendo que Ficus luschnathiana foi a espécie com maior concentração de açúcar total (51,2 %); Dipterix alata apresentou os maiores índices de açúcares redutores (5,7 %); Piper tuberculatum conteve a maior quantidade de proteína (3,3 %); Tocoyena formosa apresentou a maior atividade peroxidásica especifica (0,174 UAE/μg proteína). Verificamos uma grande variação nutricional interespecífica e intraespecífica dos frutos analisados neste trabalho. Houve predomínio de conteúdo de carboidratos com relação ao conteúdo proteico dos frutos. Este possibilita relacionar as preferências alimentares e partilha de recursos entre as espécies de morcegos frugívoros, enfatizando a importância destes frutos na regeneração florestal.

Realizou-se a determinação de nutrientes calóricos e oligoelementos macro e microminerais em dois frutos nativos do Estado de Mato Grosso do Sul (MS), o araçá ( Psidium guineense SW.) e o tarumã ( Vitex cymosa Bert). Os dados obtidos mostraram que tanto o araçá quanto o tarumã, pelo alto teor de umidade, apresentam baixo valor calórico (respectivamente, 44,5 e 39,6k cal/ 100 g). Foi verificado em ambos os frutos valores (g/ 100 g de amostra integral) de glicídios redutores e nãoredutores (respectivamente, 7,8 e 9,3) mais elevados do que os dos demais nutrientes energéticos encontrados. Em relação aos teores de minerais, o araçá apresentou maior quantidade de cálcio (26,8 mg/ 100 g), magnésio (17,9 mg/100 g), manganês (0,3 mg/ 100 g) e cobre (0,12 mg/100 g), comparativamente ao fruto tarumã. Entretanto o tarumã apresentou teores mais elevados de fósforo (21,1 mg/100 g), potássio (287,8 mg/100 g) e ferro (0,43 mg/100 g) do que o araçá. Os frutos estudados podem ser considerados, de maneira geral, boas fontes de minerais quando comparados com frutos mais comumente consumidos pela população, como a maçã, a pêra e o abacaxi. PHYSICAL-CHEMICAL CHARACTERIZATION OF ARAÇA (Psidium guineense SW.) AND TARUMÃ (Vitex cymosa Bert.) OF MATO GROSSO DO SUL STATE (BRAZIL) Abstract The determination of caloric nutrients, oligoelements and macro and microminerals in two native fruits of Mato Grosso do Sul state, the araça (Psidium guineense SW.) and the tarumã (Vitex cymosa Bert.) was realized. The obtained data showed that even for araça and for tarumã, by their high moisture content, they showed low caloric value (respectively 44.5 and 39.6 Kcal/100 g). In both fruits it was verified reducing and non-reducing sugars (g/100g sample), being respectively 7.8 and 9.3 for araça and tarumã, showing higher values than the other energetic nutrients found. In relation to the mineral content, the araça showed greater calcium content (26.8 mg/100 g), magnesium (17.9 mg/100 g), manganese (0.3 mg/100 g) and copper (0.12 mg/100 g), comparatively to tarumã fruit. Although, the tarumã showed greater content of phosphorus (21.1 mg/100 g), potassium (287.8 mg/ 100 g) and iron (0.43 mg/100 g), in comparison to the araça. The studied fruits can be considered, in a general way, good sources of minerals when compared to fruits more commonly consumed by the population as apple, pear and pineapple.
