Extração de amônio de filtros de amostragem, coleta e determinação pelo método da gota suspensa (2000)

FRANCO,Alexandre, CARDOSO,Arnaldo Alves, ALLEN,Andrew G.

A amostragem de amônia no ar é feita usualmente com filtro impregnado com ácido. O ácido ascórbico, quando usado como impregnante, é facilmente oxidado em meio básico e aquoso, gerando uma...

Bordetella pertussis waaA Encodes a Monofunctional 2-Keto-3-Deoxy-d-manno-Octulosonic Acid Transferase That Can Complement an Escherichia coli waaA Mutation

Isobe, Tomoko, White, Kimberley A., Allen, Andrew G., Peacock, Michael, Raetz, Christian R. H., Maskell, Duncan J.

Bordetella pertussis lipopolysaccharide (LPS) contains a single 2-keto-3-deoxy-d-manno-octulosonic acid (Kdo) residue, whereas LPS from Escherichia coli contains at least two. Here we report that B....

Genetic Basis for Lipopolysaccharide O-Antigen Biosynthesis in Bordetellae

Preston, Andrew, Allen, Andrew G., Cadisch, Joanna, Thomas, Richard, Stevens, Kim, Churcher, Carol M., ...

Bordetella bronchiseptica and Bordetella parapertussis express a surface polysaccharide, attached to a lipopolysaccharide, which has been called O antigen. This structure is absent from Bordetella...

Multiple Roles for Bordetella Lipopolysaccharide Molecules during Respiratory Tract Infection

Harvill, Eric T., Preston, Andrew, Cotter, Peggy A., Allen, Andrew G., Maskell, Duncan J., Miller, Jeff F.

Bordetella pertussis, Bordetella parapertussis, and Bordetella bronchiseptica are closely related subspecies that cause respiratory tract infections in humans and other mammals and express many...

Generation and Characterization of a Defined Mutant of Streptococcus suis Lacking Suilysin

Allen, Andrew G., Bolitho, Steven, Lindsay, Heather, Khan, Shahid, Bryant, Clare, Norton, Pam, ...

A defined allelic-replacement mutant of the sly gene, encoding a thiol-activated cytolysin, from a European isolate of Streptococcus suis serotype 2 was generated and characterized. Unlike the...

Identification and Cloning of waaF (rfaF) from Bordetella pertussis and Use To Generate Mutants of Bordetella spp. with Deep Rough Lipopolysaccharide

Allen, Andrew G., Isobe, Tomoko, Maskell, Duncan J.

A DNA locus from Bordetella pertussis capable of reconstituting lipopolysaccharide (LPS) O-antigen biosynthesis in Salmonella typhimurium SL3789 (rfaF511) has been isolated, by using selection with...

Distribution, Genetic Diversity, and Variable Expression of the Gene Encoding Hyaluronate Lyase within the Streptococcus suis Population

King, Samantha J., Allen, Andrew G., Maskell, Duncan J., Dowson, Christopher G., Whatmore, Adrian M.

Although Streptococcus suis is an economically important pathogen of pigs and an occasional cause of zoonotic infections of humans knowledge of crucial virulence factors, and as a consequence targets...

Bordetella pertussis risA, but Not risS, Is Required for Maximal Expression of Bvg-Repressed Genes

Stenson, Trevor H., Allen, Andrew G., Al-Meer, Jehan A., Maskell, Duncan, Peppler, Mark S.

Expression of virulence determinants by Bordetella pertussis, the primary etiological agent of whooping cough, is regulated by the BvgAS two-component regulatory system. The role of a second...
