| The need for adequate systems to guarantee the quality of food products has become more and more obvious in recent years. As a consequence, not only in Germany but throughout the world, the number of certification schemes has been increasing for nearly a decade. Due to the implementation of these standards in various countries, a considerable number of contingency factors exist that may influence the effectiveness and efficiency of such schemes. These factors include the diverse political, economic and social conditions in the different countries. Numerous studies attribute a decisive role in the successful implementation of management instruments to cultural influences. Cultural conditions may differ considerably from region to region around the world.... |

| The efficiency of the Polymerase Chain Reaction (PCR) combined with selective enrichment broth was compared with the standard microbiological techniques for detection of Salmonella Dublin in fecal samples of 10 to 15-days-old Holstein calves, experimentally infected with 10(8) CFU of Salmonella Dublin. Seventy-six fecal samples were analyzed using PCR associated with selenite cystine (SC) and Muller-Kauffmann tetrathionate (TMK) broths and standard microbiological techniques. Regardless of the selective enrichment broth used, the standard microbiological techniques were significantly better than PCR in detection of positive samples of Salmonella Dublin. However, the simultaneous use of both techniques provided detection of a larger number of positive... |

| Nitrogen concentration is an essential parameter in cyanobacterial cultures to produce enriched biomass with biotechnological purposes. Growth and biochemical composition of Nostoc LAUN0015, Nostoc UAM206, Anabaena sp.1 and Anabaena sp.2 were compared at 0, 4.25, 8.5 and 17 mM NaNO3. Cultures under laboratory conditions were maintained for 30 days at a volume of 500 mL. Anabaena sp.1 yielded the highest value of dry mass of 0.26 ± 2.49 mg mL-1 at 8.5 mM NaNO3. For chlorophyll, phycocyanin and phycoerythrin, maximum values were achieved at 17 mM NaNO3 with 18.09 ± 1.74, 102.90 ± 6.73 and 53.47 ± 2.40 μg mL-1, respectively. Nostoc LAUN0015 produced its maximum value of protein 644.86 ± 19.77 μg mL-1, and 890 mg mL-1 of carbohydrates in the absence of... |

| Abstract Our aim in this study is to compare the standard culture method with the multiplex PCR and the Speed-Oligo® Bacterial Meningitis Test (SO-BMT) – a hybridization-based molecular test method – during the CSF examination of the patients with the pre-diagnosis of acute bacterial meningitis. For the purposes of this study, patients with acute bacterial meningitis treated at the Dicle University Medical Faculty Hospital, Infectious Diseases and Clinical Microbiology Clinic between December 2009 and April 2012 were retrospectively evaluated. The diagnosis of bacterial meningitis was made based on the clinical findings, laboratory test anomalies, CSF analysis results, and the radiological images. Growth was observed in the CSF cultures of 10 out of the 57... |

| ABSTRACT This study aimed to compare method-based and newly developed sample-based methods for Mycoplasma gallisepticum (MG) detection in different samples of breeder flocks suffering from respiratory disease problems by using culture, real-time PCR (rPCR) and ELISA from chicks and embryonated eggs. Overall, 450 samples of 19-day-old chicken embryo’s trachea, 450 samples of 8-day-old chicken tracheal swabs and 900 blood samples of 20-, 27-, 34-, 40- and 46-week-old breeder chickens from 5 flocks were sampled for 26 weeks, and were all tested for MG by culture, MG-rPCR and MG-ELISA. Culturing assays and rPCR were applied to 450 mixture samples from 19-day-old chicken embryo’s trachea and 450 tracheal swab samples (each pooled into groups of 3) from... |

| Ostreopsis cf. ovata produces palytoxin analogues including ovatoxins (OVTXs) and a putative palytoxin (p-PLTX), which can accumulate in marine organisms and may possibly lead to food intoxication. However, purified ovatoxins are not widely available and their toxicities are still unknown. The aim of this study was to improve understanding of the ecophysiology of Ostreopsis cf. ovata and its toxin production as well as to optimize the purification process for ovatoxin. During Ostreopsis blooms in 2011 and 2012 in Villefranche-sur-Mer (France, NW Mediterranean Sea), microalgae epiphytic cells and marine organisms were collected and analyzed both by LC-MS/MS and hemolysis assay. Results obtained with these two methods were comparable, suggesting ovatoxins... |

| O fato de haver grande quantidade de áreas desmatadas, potencial para aproveitamento das entrelinhas de cultivos perenes e a necessidade de se ampliar a fronteira agrícola com soja, a UEPAE de Manaus iniciou uma pesquisa objetivando identificar cultivares e linhagens de soja de elevada capacidade produtiva e adaptadas as condições de baixa latitude do Estado do Amazonas. Foram avaliadas 16 cultivares. De uma maneira geral, os materiais avaliados apresentaram bons rendimentos quando comparados com outros resultados obtidos em condições de trópico úmido. As cultivares que mais se destacaram, apresentaram produtividades superiores a 2000 kg/ha, o que, para as condições de baixas latitude e fertilidade do solo de terra firme da região são animadores, tendo em... |

| The identification of Mycobacterium tuberculosis complex (MT), using non-molecular methods, is time-consuming. The objective of this study was to evaluate a screening test for the presumptive identification of MT, which could potentially decrease laboratory turn-around time for reporting preliminary results. From January 1998 to December 1999, 3056 cultures were analysed at the Mycobacterial Laboratory, Instituto Adolfo Lutz, São Paulo, Brasil. The screening test consisted of observation of colony morphology on Löwenstein Jensen medium and evaluation of cord formation on smear microscopy from those positive cultures. After the screening test, the cultures identified as non-tuberculous mycobacteria were identified to species by conventional methods (growth... |

| Since the invention of the Petri dish, there have been continuous efforts to improve efficiency in microbial cultivation. These efforts were devoted to the attainment for diverse growth conditions, simulation of in situ conditions and achievement of high-throughput rates. As a result, prokaryotes catalysing novel redox reactions as well as representatives of abundant, but not-yet cultured taxa, were isolated. Significant insights into microbial physiology have been made by studying the small number of prokaryotes already cultured. However, despite these numerous breakthroughs, microbial cultivation is still a low-throughput process. The main hindrance to cultivation is likely due to the prevailing lack of knowledge on targeted species. In this review, we... |

| Representando quase 100% da producao de graos secos entre todas as leguminosas cultivadas no Estado do Amazonas, o feijao caupi encontra-se disperso em todos os municipios amazonenses, cultivado tanto em area de varzea quanto de terra firme. As produtividades variam consideravelmente nos dois ecossistemas, enquanto em area de varzea a media gira em torno de 1000 kg/ha, em terra firme, essa media e' bastante reduzida,raramente ultrapassando aos 300 kg/ha, com excecao das mancha de "terra preta do indio" que possuem condicoes de fertilidade semelhantes as de varzea. Devido a elevada fertilidade dos solos de varzea e da otima disponibilidade de agua, luz e calor, acredita-se que as produtividades poderao ser facilmente ultrapassadas. Dai a elaboracao deste... |
