Antimicrobial susceptibility pattern of Corynebacterium striatum
(American Society for Microbiology, 1996-11-01)
The in vitro activities of 16 antimicrobial agents against 86 strains of Corynebacterium striatum were evaluated by microdilution using cation- adjusted Mueller-Hinton broth. MICs at which 90% of strains were inhibited ...

Energy-dependent accumulation of fluoroquinolones in quinolone- resistant Klebsiella pneumoniae strains
(American Society for Microbiology, 1998-07-01)
The intracellular accumulation of norfloxacin and perloxacin in Klebsiella pneumoniae was evaluated. The roles of lipopolysaccharide, capsule, and outer membrane proteins were not important for the intrabacterial accumulation ...

Cortical development associated with conjugation of Paramecium
(Company of Biologists Ltd, 1993-03)
The cortical cytoskeleton of Paramecium is characterized by a complex, polarized and asymmetrical organization. In order to analyse the cortical development of Paramecium tetraurelia during the sexual process of conjugation, ...

Uptake and intracellular activity of sparfloxacin in human polymorphonuclear leukocytes and tissue culture cells
(American Society for Microbiology, 1992-01-01)
The penetration of sparfloxacin into human neutrophils (PMN) and different tissue culture cells (HEp-2 and McCoy) was evaluated. The cellular to extracellular concentration ratios (C/E) of sparfloxacin were always higher ...

α-Tubulin of Histriculus cavicola (Ciliophora; Hypotrichea)
(Sociedad Española de Microbiología, 1997)
Se ha secuenciado un fragmento de un gen de la a-tubulina, amplificado por PCR, del cil iado hipotrico Histriculus cavicola. Este fragmento, de 1182 pb, contiene un codón de terminación (UAA) en la fase de lectura, que en ...

Intracellular penetration and activity of BAY Y 3118 in human polymorphonuclear leukocytes
(American Society for Microbiology, 1994-01-01)
The penetration of a new quinolone (BAY Y 3118) into human polymorphonuclear leukocytes (PMNs) was evaluated by a fluorometric assay. The cellular concentration-to-extracellular concentration (C/E) ratio was higher than ...

Phenotypic characteristics of 31 strains of Corynebacterium striatum isolated from clinical samples
(American Society for Microbiology, 1995)
During a 34-month period (January 1991 to October 1993), 31 Corynebacterium striatum strains recovered from clinical samples from 24 patients were characterized. Twenty (64%) strains were isolated from wound exudates, 5 ...

Outer membrane profiles of clonally related Klebsiella pneumoniae isolates from clinical samples and activities of cephalosporins and carbapenems
(American Society for Microbiology, 1998-07-01)
Fifteen isolates of Klebsiella pneumoniae producing extended-spectrum β-lactamases (ESBLs) isolated during a nosocomial outbreak were studied. The strains belonged to the same clonal type, as shown by pulsed-field gel ...

Uptake and intracellular activity of an optically active ofloxacin isomer in human neutrophils and tissue culture cells
(American Society for Microbiology, 1990-01-01)
The penetration of an optically active ofloxacin isomer [(-)-ofloxacin] into human neutrophils and different tissue culture cells (HEp-2, McCoy, MDCK, and Vero) was studied and compared with that of ofloxacin by a fluorometric ...

Resistance of Pseudomonas aeruginosa to imipenem induced by eluates from siliconized latex urinary catheters is related to outer membrane protein alterations
(American Society for Microbiology, 1999-02-01)
The activity of imipenem against Pseudomonas aeruginosa HUS-3 decreased by 16 times in the presence of substances eluted from siliconized latex urinary catheters (SLUCs). SLUCs did not inactivate imipenem or increase β- ...
