13. Detecção de sementes de arroz mutante tolerante ao herbicida imazethapyr
O objetivo deste trabalho foi desenvolver metodologias, fundamentadas no teste de germinação, para detecção de sementes de arroz mutante tolerante ao herbicida imazethapyr. Foram conduzidos dois experimentos, cada um constituído de duas etapas. No experimento 1, foi utilizada a metodologia do papel umedecido na solução do herbicida. Na primeira etapa,

14. Clinical and laboratory characteristics of Achromobacter xylosoxidans infection.
Achromobacter xylosoxidans was isolated from six patients. The organism causes opportunistic infections in patients who are compromised. A. xylosoxidans is a catalase- and oxidase-positive, motile, gram-negative rod that oxidizes xylose and glucose. The organism exists in a water environment and may be confused with Pseudomonas species. Unlike pseudomonas, a

15. Cloning of a gene from Pseudomonas sp. strain PG2982 conferring increased glyphosate resistance.
A plasmid carrying a 2.4-kilobase-pair fragment of DNA from Pseudomonas sp. strain PG2982 has been isolated which was able to increase the glyphosate resistance of Escherichia coli cells. The increase in resistance was dependent on the presence of a plasmid-encoded protein with a molecular weight of approximately 33,000, the product of a translational fusion

16. Diagnosis of vascular catheter-related bloodstream infection: a meta-analysis.
Catheter-related bloodstream infections increased in incidence during the past decade, causing significant morbidity, mortality, and excess hospital costs. Absence of inflammation at the catheter site in most cases makes clinical diagnosis uncertain. The relative accuracy and cost-effectiveness of different microbiologic tests for confirming that bloodstream
