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 ...
Staphylococcus aureus develops an alternative, ica-independent biofilm in the absence of the arlRS two-component system
(American Society for Microbiology, 2005)
info:eu-repo/semantics/article,
The biofilm formation capacity of Staphylococcus aureus clinical isolates is considered an important virulence
factor for the establishment of chronic infections. Environmental conditions affect the biofilm formation
capacity ...
SarA is an essential positive regulator of Staphylococcus epidermidis biofilm development
(American Society for Microbiology, 2005)
info:eu-repo/semantics/article,
Staphylococcus epidermidis biofilm formation is associated with the production of the polysaccharide intercellular
adhesin (PIA)--poly-N-acetylglucosamine polysaccharide (PNAG) by the products of the icaADBC
operon. ...
SarA positively controls Bap-dependent biofilm formation in Staphylococcus aureus
(American Society for Microbiology, 2005)
info:eu-repo/semantics/article,
The biofilm-associated protein Bap is a staphylococcal surface protein involved in biofilm formation. We
investigated the influence of the global regulatory locus sarA on bap expression and Bap-dependent biofilm
formation ...
Beta-lactam antibiotics induce the SOS response and horizontal transfer of virulence factors in Staphylococcus aureus
(American Society for Microbiology, 2006)
info:eu-repo/semantics/article,
Antibiotics that interfere with DNA replication and cell viability activate the SOS response. In Staphylococcus
aureus, the antibiotic-induced SOS response promotes replication and high-frequency horizontal transfer ...
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 ...
Sf29 Gene of Spodoptera frugiperda multiple nucleopolyhedrovirus is a viral factor that determines the number of virions in occlusion bodies
(American Society for Microbiology, 2008)
info:eu-repo/semantics/article,
The genome of Spodoptera frugiperda multiple nucleopolyhedrovirus (NPV) was inserted into a bacmid
(Sfbac) and used to produce a mutant lacking open reading frame 29 (Sf29null). Sf29null bacmid DNA was
able to generate ...
Extensive rearing hinders Maedi-Visna Virus (MVV) infection in sheep
(EDP Sciences, 2006)
info:eu-repo/semantics/article,
Maedi-Visna Virus (MVV) seroprevalence and its relationship with housing and mode
of rearing of replacement ewe-lambs was investigated in 38 non-randomly selected sheep-flocks in
Spain. They included extensive lamb-producing ...
Maedi-visna virus infection of ovine mammary epithelial cells
(EDP Sciences, 2006)
info:eu-repo/semantics/article,
The aim of this work was to perform a complete study of maedi-visna virus (MVV)
infected mammary glands of naturally-infected sheep, and to determine if cells other than
macrophages undergo a productive viral infection in ...
