Análise de desenvolvimento do tambaqui, Colossoma macropomum (Cuvier, 1818) (Pisces, Serrasalmidae), utilizando a massa de mandioca branca, Manihot esculenta (Crantz) como complemento alimentar em viveiros de piscicultura em área de várzea

O Estado possui condições favoráveis para o desenvolvimento da piscicultura, que se constituirá numa alternativa para a produção de proteínas de origem animal, capaz de auxiliar na redução dos acentuados déficits encontrados na dieta alimentar da população paraense de baixa renda, assim como, minimizar os problemas pontuais causados pela sobrepesca e poluição química. E as várzeas da Amazônia brasileira, constituem-se então, num grande potencial para o desenvolvimento da piscicultura racional, mantendo a sustentabilidade do ecossistema através de tecnologias de manejo, em substituição aos métodos extrativistas tradicionais e predatórios. Um dos principais entraves da piscicultura é o elevado custo a ração que chega a compor até 80% do custo total da atividade, visto que não existe uma dieta com produtos regionais que baixasse esse custo, O custo das rações extrusadas ofertadas na região extrapola o limite da economia, devido principalmente à agregação do frete, vista a escassez das indústrias locais, assim como os altos preços dos principais insumos, notadamente em se tratando da fração protéica que é mais onerosa da dieta. Com base nessa realidade, a região Amazônica lança mão de subprodutos da agroindústria de fácil aquisição e baixo custo, para minimizar os gastos com a piscicultura e garantir a presença do peixe na mesa da população, que é o alimento mais consumido. No experimento a espécie utilizada foi o tambaqui, Colossoma macropomum é uma espécie ideal para piscicultura em área de várzea em virtude da sua rusticidade. Com isso o estudo de dietas alternativas possibilita um cultivo que viabilize economicamente a prática. O experimento foi realizado na área de várzea da UFRA, onde foram submetidos a 3 tratamentos, onde: V1) foi ministrado ração extrusada 28% P.B.; V2) ração comercial extrusada 28% parcelada com massa de mandioca branca e V3) foi ministrado massa de mandioca branca. Ao final do experimento observou-se que o viveiro onde foi ministrado ração comercial apresentou melhor desempenho zootécnico, porém o viveiro 2 onde foi ministrado ração comercial extrusada 28% parcelada com massa de mandioca branca apresentou um desempenho similar ao anterior, obtendo consumo 50% menor de ração extrusada.

Brainstem abscess of undetermined origin: microsurgical drainage and brief antibiotic therapy

CONTEXTO:Abscessos isolados do tronco encefálico são raros e geralmente associados a outras infecções. Trata-se de condição grave, com grande morbidade e mortalidade. Opções cirúrgicas são aspiração com estereotaxia e drenagem microcirúrgica. Antibioticoterapia sistêmica tem sido usada por mais de seis semanas.RELATO DE CASO:Apresentamos o caso de um jovem com abscesso pontino sem outras infecções sistêmicas. O paciente foi tratado com drenagem microcirúrgica e antibioticoterapia por três semanas. Houve boa evolução pós-operatória.CONCLUSÕES:Acesso microcirúrgico pode ser considerado uma opção importante no tratamento de grandes abscessos do tronco encefálico, que são multiloculados, próximos da superfície ou que contenham líquido espesso. Drenagem completa do material purulento pode diminuir o período de antibioticoterapia.

Análise microbiológica e físico-química de material proteico comestível derivado do processamento da gordura oriunda do abate de bovinos

Background: The use of all by-products of bovine slaughter is of high economic importance for the industries of products of animal origin. Among these products, fat has an important role, once fat rendering may generate several different products, such as protein material that may be used in the manufacture of meat products. However, in spite of the importance that the use of all by-products has for the economic balance of the industry, there are no reports on their use in Brazil, or studies that supply data on microbiological and physical-chemical local standards for this protein. Thus, the objective of this study was to evaluate microbiological and physical-chemical characteristics of protein material obtained from fat rendering, as well as to provide support for companies to use fat rendering to generate protein material, adding value to industrialized meat products.Materials, Methods & Results: The experimental production of edible protein obtained of fat rendering was conducted in slaughterhouse with supervision of the Brazilian Ministry of Agriculture, Livestock and Food Supply. Protein material was obtained in a continuous, humid heat system at high temperatures. Fat scraps containing protein were ground and cooked at high temperature (85 degrees C), and placed in a three phase decanter centrifuge. After centrifugation, protein material was ground again and packed. Samples were collected from 15 batches of protein material, and the following microbiological analyses were carried out: counts of aerobic mesophilic and psychrotrophic microorganisms, coliforms at 35 degrees C, Escherichia coli, sulfite-reducing Clostridium, and Staphylococcus aureus, besides presence or absence of Salmonella and Listeria monocytogens. The following physical-chemical analyses were also carried out: protein, total lipid, moisture, ash, carbohydrate, and energy content. Mean counts of mesophiles, psychrotrophs, and coliforms at 35 degrees C were 4.17; 3.69 and 1.87 (log CFU/g), respectively. Levels of protein, total lipids, moisture, ashes and carbohydrates were 27.50; 7.83; 63.88%; 0.24%; and 0.55%, respectively, and energy content was 182.63 kcal/100g.Discussion: Results of microbiological analyses demonstrated that, although low, the final product showed to be contaminated. Contamination that occurred during the second grinding procedure may be an explanation for these bacterial counts. Also, the temperature used for fat fusion was not enough to eliminate thermoduric microorganisms. However, even with the presence of indicator microorganisms in the samples, none was contaminated by E. coli, sulfite-reducing Clostridium, S. aureus, Salmonella or L. monocytogenes. Physical-chemical analyses showed that the product had adequate nutritional quality. Based on these results, it was possible to conclude that protein material obtained in fat rendering showed characteristics that enable the use of this product as raw material for processed meat products. Besides, the present study was the first one to present scientific results in relation to edible by-products obtained in fat rendering, supplying important information for slaughterhouses and meat-processing plants. The study also produced relevant data on the innocuousness of the product, which may be used to guide decision-making of health inspectors.

Extensive Cervical Necrotizing Fasciitis of Odontogenic Origin

Necrotizing fasciitis (NF) is an uncommon infection, but potentially lethal, especially when associated with systemic disorders such as diabetes. The authors report a case of necrotizing fasciitis from odontogenic origin in a patient with uncontrolled diabetes mellitus. The initial diagnosis was based on clinical information, in which multiple necrosis areas in cervical and thoracic regions were observed. Wide antibiotic therapy was applied, followed by surgical drain age and debridement. Culture was positive for methicillin-resistant Staphylococcus aureus. Although the treatment is established, the patient dies after sepsis and failure of vital organs. Clearly, the morbidity associated to this infection, even in diabetic patients, can be minimized if an early diagnosis and effective debridement are done.

A utilização da monensina sódica na bovinocultura

The global growing demand for food coupled with the direction of eating habits for products of animal origin, become even more necessary the search for alternatives to increase production. In this way, improve animal performance through the use of ionophores has become an effective measure to increase production and profitability of farms. Among the ionophores, monensin is the best known so far, as to their effect on the pattern of rumen fermentation and its consequences on animal production, especially by improving the quality or quantity of nutrients available for absorption through the gastrointestinal tract and consequently the performance of ruminants

Qualidade microbiológica de peixes e frutos do mar em Botucatu, SP

whole world. The world production of fish is around 100 million tons/year and 70% of them is destined exclusively to the human feeding. The fish and derived have a great importance in the human diet, contributing with ¼ of offer of protein of animal origin. Sseafood and fish are health, because they are rich in proteins, vitamins, micronutrients and insatured fats. However, one of the most important themes, in public health, refers to the safe food. Only in the USA, 76 million case of foodborne diseases occurs every year, with 325 thousand hospitalized and 5 thousand deaths. According to the microbiological parameters, the Brazilian Food Sanitation Standard (Decree No. 12, 2001) defined that fish, roes of fish, crustaceans and mollusks in natura cooled or frozen, no consumed raw should present up to 103 MPN of coagulase positive Staphylococcus in the absence of Salmonella in 25g. Based on this, this work verified the microbiological quality of fish and seafood retailed in supermarkets and fish store in Botucatu city. A hundred samples were analyzed, being 65 frozen (65%) and 35 cooled (35%). The samples included various kinds of fish and seafood. Among the frozen samples, 31 were fish and 34 seafood. About the cooled ones, 28 were fish and 7 seafood. The methods used for analysis are in agreement with APHA (2001). The samples were acquired in 4 establishments (3 supermarkets and a fish store). Ina total of 100 samples, all were negative to coagulase positive Staphylococcus and 2 were positive for Salmonella (2%). According to the results, we conclude that the presence of Salmonella is a risk factor for the consumers' health and these foods should not be consumed raw. In spite of the freezing to be a good conservation way, this process doesn't totally eliminate the pathogens of the food
