Salmonella spp. em carcaças, carne mecanicamente separada, lingüiças e cortes comerciais de frango

Alimentos de origem animal representam papel fundamental na epidemiologia das salmoneloses humanas. Apesar dos avanços tecnológicos, a carne de frango ainda é passível de contaminação bacteriana, especialmente por microrganismos do gênero Salmonella, que podem encontrar-se albergados no trato intestinal ou em outra parte do corpo das aves. O presente trabalho objetivou pesquisar a ocorrência de Salmonella em carne de frango e derivados procedentes da região Nordeste do Estado de São Paulo. Foram analisadas, através do método convencional de cultivo, 45 amostras de carcaças, 60 de carne mecanicamente separada (CMS), 25 de lingüiça de frango, 20 de peito, e 15 de coxa e sobre-coxa. Salmonella spp. foi encontrada em 13,3% (6/45) das carcaças, 25% (15/60) das amostras de CMS, 16% (4/25) das lingüiças, 30% (6/20) dos peitos e 13,3% (2/15) das coxas e sobre-coxas analisadas. do total de 165 amostras analisadas, 33 (20%) apresentaram contaminação por Salmonella estando, portanto, impróprias para o consumo conforme legislação brasileira.

Thus being, it has that to study intensely, what it has come to be fact, the alternative power plants, as well as the technologies economically capable to ultilizar them. The potential demand of biodiesel for 2020 is taken in consideration that, in accordance with the International Agency of Energia (AIE), in only eight countries, will jump of 34,7 million tons in 2010 for 133,8 million in 2020, with an increment next to 300%. The tame nut is a producing oil plant with all the qualities necessary to be transformed into oil diesel. Beyond perennial and of easy culture, it presents good conservation of the harvested seed, being able to become great producer of substance cousin as optional fuel source. For these authors, this is a culture that can be developed in the small properties, with the available familiar man power, being plus a source of income for the country properties of the Northeast Region. The objective of this work is to evidence the capacity of oil production of the nut-bellwether, and the quality of extration with hexano and methanol in 6 distinct times.

The first report of Hepatozoon sp (Apicomplexa : Hepatozoidae) in neotropical felids from Brazil

In order to investigate the occurrence of Hepatozoon infection in Neotropical felids from Brazil, blood from the jugular or cephalic vein was taken from 29 non-domestic felids including ocelot (Leopardus pardalis), little spotted cat (Leopardus tigrinus), margay (Leopardus wiedii), and jaguarondi (Puma yagouaroundi) from the Northeast region of Brazil. Hepatozoon infection was confirmed by light microscopy and molecular techniques. The results showed five naturally infected felids. Partial sequences of the 18S rRNA gene of the Hepatozoon sp. from these felids were further analyzed. Sequences revealed that the isolates found are closely related to Hepatozoon sp. from domestic cats in Spain. Hepatozoon species from Neotropical felids were identified molecularly and characterized for the first time. This is also the first report of Hepatozoon infection in a little spotted cat.

Phenology of a dioecious population of Batrachospermum delicatulum (Batrachospermales, Rhodophyta) in a stream from southeastern Brazil

The seasonal dynamics of a dioecious population of Batrachospermum delicatulum (Skuja) Necchi and Entwisle was evaluated biweekly during the growth period of the macroscopic gametophyte, from late autumn (May) to early spring (October) in a third-order stream from the northeast region of Sao Paulo State, southeastern Brazil (20°43'S, 49°13'W). The population fluctuated throughout the study period in terms of percentage cover, frequency and chlorophyll content. Percent cover and frequency showed a clear pattern with the lowest values at the initial and final stages of the growth period and the highest in July-August (winter). Gametophyte growth was associated with high illumination and low temperature, which agrees with most observations on Batrachospermales in stream environments. Relatively wide variations in reproductive characteristics were observed during the growth period, which were not correlated with percentage cover, frequency and chlorophyll content. The phenologic pattern observed in this population was characterized by a synchronic development of female/male plant ratio with the number of spermatangia per plant resulting in. (i) a higher proportion of fertilized (carposporophytic) plants associated with more male plants; (ii) higher fertilization rates during the periods with higher production of spermatangia per plant; and (iii) higher production of spermatangia per plant when the population had more male plants. These characteristics were largely associated with water temperature and ion content. In terms of reproductive success, the population studied can be regarded as highly efficient, considering the relatively low proportion of male to female plants and high fertilization rates. These data are consistent with a hypothesis to explain high fertilization rates in dioecious species in lotic habitats consisting of outcrossing among adjacent plants with intermingled male and female branches within an algal cluster. Efficient reproductive strategies have been reported in dioecious, monoecious and even mixed populations of B. delicatulum and can be interpreted as adaptations to successfully colonize streams with different characteristics.

Diques clásticos na formação corumbataí (p) no nordeste da bacia do paraná, SP: Análise sistemática e significações estratigráficas, sedimentológicas e tectônicas

This paper aims to present the results of systematic survey on clastic dykes in the Corumbataí Formation (Permian), in the northeast region of the State of São Paulo. Besides this, the paper analyses genetic aspects of those features as well as their stratigraphic and sedimentologic implications in terms of geologic evolution of the northeastern Paraná Sedimentary Basin during Permian times. The field works had been developed in 3 main Corumbataí Formation outcrops (2 road cuts and a quarry) supposed to show the most important clastic dikes occurrences in the studied area. Basically, the sedimentary intrusions are formed by fine sand or silt size particles and had penetrated host rocks as near-vertical, centimeter thick, dykes (most common form) or as horizontal sheets, forming clastic sills (subsidiary form), both with variable geometric forms and dimensions. A lot of dyke walls show undulations suggesting pre-diagenetic clastic intrusions, probably near the ancient depositional surface. Almost all intrusions occur in the superior third portion of the Corumbataí Formation and some similar features seem to appear in the adjoining superposed Pirambóia Formation base. In this article the authors defend a seismic origin hypothesis for the clastic intrusions. It is important to mention that clastic intrusions tend to occur linked to expressive seismic events, with magnitude upper to 5. The analysis of isopach maps of the Permian and Mesozoic units of the Paraná Sedimentary Basin in the study area suggests a depositional system changing, from epicontinental sea conditions to shallow platform and, finally, to coastal deserts. Probably, this environmental change was driven by regional uplift accompanied by seismic events. It is possible that ancient seismicity triggered liquefaction processes and the resulting clastic intrusions. In this sense, those clastic features might be properly namedseismites.

Situação da agricultura irrigada no Brasil de acordo com o censo agropecuário 2006

Knowledge about irrigated agricultural area and its geographical distribution are of great importance to water resources management. Evolution of irrigated area according to the irrigation method allows an identification of rational water technologies. The aim of this work was to analyze the information presented in the agricultural census of 1995/1996 and of 2006. Brazil has an area of 4.45 million cultivated hectares with irrigation. It is noticed that according to the 1995/1996 census, the irrigated area increased 1.3 million hectares, a growth of 42%. The Southeast region surpasses the South region which had, in 1995/96, the largest irrigated area. The Northeast region is the third irrigated agricultural area with 22.12 %, while the Central-west and the Northern region together sum 14.7%. According to the agricultural census 2006 classification, sprinkler irrigation (without center pivot) method is the most used,followed by flood, center pivot, other methods, drip and furrow, representing 35.3%, 24.4%, 18.9%, 8.3%, 7.4% and 5.8%, respectively.

Análise da produção e comercialização de mel natural no Brasil no período de 1999 a 2010

The aim of this study was to analyze the evolution of natural honey production in Brazil, as well as the Brazilian performance in the international markets and their own consumption behavior of natural honey in the domestic market. For this study, we used descriptive analysis of time series information, data production and export of natural honey understood, respectively, for the periods 1999 to 2010. To analyze the correlation between the series of apparent consumption per capita (variable X) and the international price data (variable Y), we used the statistical analysis of the correlation coefficient of Pearson (CP). Main results revealed that the Brazilian production of natural honey has more than doubled in the last decade, while the Northeast region was the largest contributor to this performance. This increase in the production was mainly directed towards supplying the international market, which currently consumes more than half of Brazilian production. It is true that the change in the international market price has a direct effect on domestic supply, but the Brazilian domestic market has potential for increasing effective consumer who deserves to be better exploited; it implies to pay attention to the supply of quality natural honey, quantity and regularity.

Moral judgment competence of medical students: a transcultural study

The authors conducted a cross-sectional short-term study using Lind's Moral Judgment Test (MJT) to compare moral judgment competence (C-score) among students from a medical school in the Northeast region of Brazil and a medical school in the Northern region of Portugal. This study compares the C-scores of groups in the first and eighth semesters of study within each medical school and groups from corresponding semesters between the two medical schools. This study also evaluates the influence of such factors as age and gender on moral competence. A regression of moral judgment competence among the students in their eighth semester versus the students in the first semester of Brazilian medical school (p < 0.001) and a stagnation of moral competence among students in their eighth semester versus the first semester students in the Portuguese medical school (p = 0.06) were observed. For both the first semester and eighth semester groups, the students in the Portuguese medical school had higher C-scores than the students in the Brazilian medical school. In the analysis of the students' performances in terms of MJT dilemmas, the phenomenon of moral segmentation was observed in all of the groups, and the students performed better on the worker's dilemma than on the doctor's dilemma. Among students in the same semester of study, older students had lower C-scores. There was generally no significant difference between men's and women's C-scores. © 2013 Springer Science+Business Media Dordrecht.
