Assessment of the quality of dna extracted by two techniques from Mycobacterium tuberculosis for fast molecular identification and genotyping BJM
Miyata,Marcelo; Santos,Adolfo Carlos Barreto; Mendes,Natália Helena; Cunha,Eunice Atsuko; Melo,Fernando Augusto Fiúza de; Leite,Clarice Queico Fujimura.
We report a comparative study of two DNA extraction techniques, thermolysis and chemical lysis (CTAB), for molecular identification and genotyping of M. tuberculosis. Forty DNA samples were subjected to PCR and the results demonstrated that with thermolysis it is possible to obtain useful data that enables fast identification and genotyping.

Comparison of resazurin microtiter assay performance and BACTEC MGIT 960 in the susceptibility testing of Brazilian clinical isolates of Mycobacterium tuberculosis to four first-line drugs BJM
Miyata,Marcelo; Pavan,Fernando Rogério; Sato,Daisy Nakamura; Marino,Leonardo Biancolino; Hirata,Mario Hiroyuki; Cardoso,Rosilene Fressati; Melo,Fernando Augusto Fiúza de; Leite,Clarice Queico Fujimura.
We assessed the performance of REMA in comparison with BACTEC MGIT 960 in the susceptibility testing of 80 Mycobacterium tuberculosis clinical isolates from Clemente Ferreira Institute against four drugs. REMA proved to be a rapid and accurate method, providing excellent correlation with BACTEC MGIT 960, with the exception of results for the ethambutol drug.

Quantitative trait loci (QTL) mapping in livestock allows the identification of genes that determine the genetic variation affecting traits of economic interest. We analyzed the birth weight and weight at 60 days QTL segregating on bovine chromosome BTA14 in a F2 resource population using genotypes produced from seven microsatellite markers. Phenotypes were derived from 346 F2 progeny produced from crossing Bos indicus Gyr x Holstein Bos taurus F1 parents. Interval analysis to detect QTL for birth weight revealed the presence of a QTL (p < 0.05) at 1 centimorgan (cM) from the centromere with an additive effect of 1.210 ± 0.438 kg. Interval analysis for weight at 60 days revealed the presence of a QTL (p < 0.05) at 0 cM from the centromere with an...

Quantitative trait locus affecting birth weight on bovine chromosome 5 in a F2 Gyr x Holstein population Genet. Mol. Biol.
Gasparin,Gustavo; Miyata,Marcelo; Coutinho,Luiz Lehmann; Martinez,Mário Luiz; Silva,Marcos Vinícius G. Barbosa da; Machado,Marco Antônio; Campos,Ana Lúcia; Regitano,Luciana Correia de Almeida.
Segregation between a genetic marker and a locus influencing a quantitative trait in a well delineated population is the basis for success in mapping quantitative trait loci (QTL). To detect bovine chromosome 5 (BTA5) birth weight QTL we genotyped 294 F2 Gyr (Bos indicus) x Holstein (Bos taurus) crossbreed cattle for five microsatellite markers. A linkage map was constructed for the markers and an interval analysis for the presence of QTL was performed. The linkage map indicated differences in the order of two markers relative to the reference map (<A HREF="http://www.marc.usda.gov/">http://www.marc.usda.gov</A>). Interval analysis detected a QTL controlling birth weight (p < 0.01) at 69 centimorgans (cM) from the most centromeric marker...
