A pyrF auxotrophic mutant of Sinorhizobium fredii HH103 impaired in its symbiotic interaction with soybean and other legumes
(Sociedad Española de Microbiología. Viguera Editores, 2007)
Transposon Tn5-Mob mutagenesis allowed the selection of a Sinorhizobium fredii HH103 mutant derivative (SVQ 292) that requires the presence of uracil to grow in minimal media. The mutated gene, pyrF, codes for an ...

Zinc eluted from siliconized latex urinary catheters decreases OprD expression, causing carbapenem resistance in Pseudomonas aeruginosa
(American Society for Microbiology, 2003-07-01)
The activities of carbapenems against Pseudomonas aeruginosa decreased in the presence of siliconized latex urinary catheters (SLUCs). This effect was associated with the loss of OprD. The zinc that eluted from SLUCs is ...

Activities of ABT-773 against Listeria monocytogenes and coryneform bacteria of clinical interest
(American Society for Microbiology, 2003-04-01)
The in vitro activities of ABT-773 were evaluated against 15 Listeria monocytogenes strains and 196 coryneform bacteria isolated from clinical samples. One hundred percent of the L. monocytogenes strains were inhibited by ...

Uptake and intracellular activity of linezolid in human phagocytes and nonphagocytic cells
(American Society for Microbiology, 2002-12-01)
The intracellular penetration and activity of linezolid in human polymorphonuclear leukocytes and tissue-cultured cells (McCoy) were evaluated. Linezolid reached intracellular concentrations slightly greater than extracellular ...

Role of Klebsiella pneumoniae LamB porin in antimicrobial resistance
(American Society for Microbiology, 2003-10-01)
To investigate the contribution of LamB in Klebsiella pneumoniae antimicrobial resistance, we determined the MICs of various antibiotics and the frequency of mutation to increased cefoxitin or meropenem resistance of the ...

Intracellular penetration and activity of gemifloxacin in human polymorphonuclear leukocytes
(American Society for Microbiology, 2000-11-09)
The intracellular penetration and activity of gemifloxacin in human polymorphonuclear leukocytes (PMN) were evaluated. Gemifloxacin reached intracellular concentrations eight times higher than extracellular concentrations. ...

Inactivation of the "Sinorhizobium fredii" HH103 "rhcJ" gene abolishes nodulation outer proteins (Nops) secretion and decreases the symbiotic capacity with soybean
(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 ...

Characterization of a clinical isolate of Haemophilus influenzae with a high level of fluoroquinolone resistance
(Oxford University Press, 2006-01-23)
Haemophilus influenzae is one of the bacterial pathogens most likely to be involved in community-acquired respiratory infections in patients with chronic obstructive pulmonary disease. In this species, resistance to ...
