1. VÃbrio em camarÃo e na Ãgua de trÃs fazendas de carcinicultura do Cearà / Vibrio in shrimp and water from three shrimp farms in CearÃ
O presente estudo teve por objetivo quantificar Vibrio, vibrios sac+ e sac â e identificar as espÃcies de Vibrio, presentes no cultivo do camarÃo Litopenaeus vannamei e na Ãgua onde à ele cultivado. Acompanharamse dois ciclos do cultivo do L. vannamei em trÃs fazendas (A, B e C),situadas nos estuÃrios dos rios AcaraÃ, Coreaà e Jaguaribe (CE), de ago

2. Cloning and sequencing of the sacA gene: characterization of a sucrase from Zymomonas mobilis.
The Zymomonas mobilis gene (sacA) encoding a protein with sucrase activity has been cloned in Escherichia coli and its nucleotide sequence has been determined. Potential ribosome-binding site and promoter sequences were identified in the region upstream of the gene which were homologous to E. coli and Z. mobilis consensus sequences. Extracts from E. coli cel

3. Identification of additional genes required for O-antigen biosynthesis in Vibrio cholerae O1.
The cloning and expression of the genes encoding the Vibrio cholerae O1 lipopolysaccharide O antigen in a heterologous host have been described previously (P. A. Manning, M. W. Heuzenroeder, J. Yeadon, D. I. Leavesley, P. R. Reeves, and D. Rowley, Infect. Immun. 53:272-277, 1986). It was thus assumed that all the genes required for O-antigen expression were

4. Ecological relationships between Vibrio cholerae and planktonic crustacean copepods.
Strains of Vibrio cholerae, both O1 and non-O1 serovars, were found to attach to the surfaces of live copepods maintained in natural water samples collected from the Chesapeake Bay and Bangladesh environs. The specificity of attachment of V. cholerae to live copepods was confirmed by scanning electron microscopy, which revealed that the oral region and egg s
