Brucellosis vaccines: assessment of brucella melitensis lipopolysaccharide rough mutants defective in core and O-polysaccharide synthesis and export
(Public Library of Science, 2008)
Artículo / Artikulua,
Background: The brucellae are facultative intracellular bacteria that cause brucellosis, one of the major neglected zoonoses. In endemic areas, vaccination is the only effective way to control this disease. Brucella ...
Towards the identification of the common features of bacterial biofilm development
(Sociedad Española de Microbiología, 2006)
Artículo / Artikulua,
Los microorganismos pueden vivir y proliferar como células individuales que nadan libremente en el medio o crecer en comunidades multicelulares muy bien organizadas dentro de una matriz que ellas mismas han sintetizado y ...
Mixtures of complete and pif1- and pif2-deficient genotypes are required for increased potency of an insect nucleopolyhedrovirus
(American Society for Microbiology, 2009)
info:eu-repo/semantics/article,
The insecticidal potency of a nucleopolyhedrovirus population (SfNIC) that infects Spodoptera frugiperda
(Lepidoptera) is greater than the potency of any of the component genotypes alone. Occlusion bodies (OBs)
produced ...
Relevant role of fibronectin-binding proteins in Staphylococcus aureus biofilm-associated foreign-body infections
(American Society for Microbiology, 2009)
info:eu-repo/semantics/article,
Staphylococcus aureus can establish chronic infections on implanted medical devices due to its capacity to form biofilms. Analysis of the factors that assemble cells into a biofilm has revealed the occurrence of strains ...
Role of the Omp25/Omp31 family in outer membrane properties and virulence of Brucella ovis
(American Society for Microbiology, 2007)
info:eu-repo/semantics/article,
The genes coding for the five outer membrane proteins (OMPs) of the Omp25/Omp31 family expected to be located in the outer membrane (OM) of rough virulent Brucella ovis PA were inactivated to evaluate their role in virulence ...
BvrR/BvrS-controlled outer membrane proteins Omp3a and Omp3b are not essential for Brucella abortus virulence
(American Society for Microbiology, 2007)
info:eu-repo/semantics/article,
The Brucella abortus two-component regulatory system BvrR/BvrS controls the expression of outer membrane proteins (Omp) Omp3a (Omp25) and Omp3b (Omp22). Disruption of bvrS or bvrR generates avirulent mutants with altered ...
B regulates IS256-mediated Staphylococcus aureus biofilm phenotypic variation
(American Society for Microbiology, 2007)
info:eu-repo/semantics/article,
Biofilm formation in Staphylococcus aureus is subject to phase variation, and biofilm-negative derivatives emerge sporadically from a biofilm-positive bacterial population. To date, the only known mechanism for generating ...
Conditional mutation of an essential putative glycoprotease eliminates autolysis in Staphylococcus aureus
(American Society for Microbiology, 2007)
info:eu-repo/semantics/article,
Our previous studies demonstrated that a putative Staphylococcus aureus glycoprotease (Gcp) is essential for bacterial survival, indicating that Gcp may be a novel target for developing antibacterial agents. However, the ...
Glycogen phosphorylase, the product of the glgP Gene, catalyzes glycogen breakdown by removing glucose units from the nonreducing ends in Escherichia coli
(American Society for Microbiology, 2006)
info:eu-repo/semantics/article,
To understand the biological function of bacterial glycogen phosphorylase (GlgP), we have produced and characterized Escherichia coli cells with null or altered glgP expression. glgP deletion mutants (ΔglgP) totally lacked ...
Protein A-mediated multicellular behavior in Staphylococcus aureus
(American Society for Microbiology, 2008)
info:eu-repo/semantics/article,
The capacity of Staphylococcus aureus to form biofilms on host tissues and implanted medical devices is one of the major virulence traits underlying persistent and chronic infections. The matrix in which S. aureus cells ...
