Impaired Virulence and In Vivo Fitness of Colistin-Resistant Acinetobacter baumannii [Article]
(Oxford University Press, 2011-01-07)
Acinetobacter baumannii (American Type Culture Collection strain 19606) acquires mutations in the pmrB gene during the in vitro development of resistance to colistin. The colistin-resistant strain has lower affinity for ...
N-acetylcysteine selectively antagonizes the activity of imipenem in Pseudomonas aeruginosa by an OprD-mediated mechanism [Article]
(American Society for Microbiology, 2015-01-01)
The modulating effect of N-acetylcysteine (NAC) on the activity of different antibiotics has been studied in Pseudomonas aeruginosa. Our results demonstrate that, in contrast to previous reports, only the activity of ...
Genomewide overexpression screen for fosfomycin resistance in Escherichia coli: Mura confers clinical resistance at low fitness cost [Article]
(American Society for Microbiology, 2012-05-01)
To determine whether the overexpression of chromosomal genes can confer fosfomycin resistance, genomewide screening of a complete set of 5,272 plasmid-expressed open reading frames of Escherichia coli (ASKA collection) was ...
Inactivation of the "Sinorhizobium fredii" HH103 "rhcJ" gene abolishes nodulation outer proteins (Nops) secretion and decreases the symbiotic capacity with soybean [Article]
(Sociedad Española de Microbiología, Viguera Editores, 2006)
Se ha propuesto que las proteínas externas de nodulación (Nops) impiden la nodulación efectiva de Sinorhizobium fredii USDA257 con las sojas americanas. S. fredii HH103 nodula de forma natural tanto conlas sojas asiáticas ...
Exopolysaccharide Production by Sinorhizobium fredii HH103 Is Repressed by Genistein in a NodD1-Dependent Manner [Article]
(Public Library of Science, 2016)
In the rhizobia-legume symbiotic interaction, bacterial surface polysaccharides, such as exopolysaccharide (EPS), lipopolysaccharide (LPS), K-antigen polysaccharide (KPS) or cyclic glucans (CG), appear to play crucial roles ...
In vitro effect photodynamic therapy with differents photosensitizers on cariogenic microorganisms [Article]
(BioMed Central, 2015)
Background Antimicrobial photodynamic therapy has been proposed as an alternative to suppress subgingival species. This results from the balance among Streptococcus sanguis, Streptococcus mutans and Candida albicans in ...
