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 ...

hSiah2 is a new vav binding protein which inhibits Vav-mediated signaling pathways
(1999)
The hematopoietic proto-oncogene vav has been characterized as a Rac1- GDP/GTP exchanger protein which regulates cytoskeletal reorganization as well as signaling pathways leading to the activation of stress-activated protein ...

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 ...

A broad molecular phylogeny of ciliates: Identification of major evolutionary trends and radiations within the phylum
(National Academy of Sciences, 1992)
The cellular architecture of ciliates is one of the most complex known within eukaryotes. Detailed systematic schemes have thus been constructed through extensive comparative morphological and ultrastructural analysis of ...

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 ...

Development of resistance during antimicrobial therapy caused by insertion sequence interruption of porin genes
(American Society for Microbiology, 1999-01-01)
We have demonstrated by using an in vitro approach that interruption of the OmpK36 porin gene by insertion sequences (ISs) is a common type of mutation that causes loss of porin expression and increased resistance to ...

Grb2 and Its Apoptotic Isoform Grb3-3 Associate with Heterogeneous Nuclear Ribonucleoprotein C, and These Interactions Are Modulated by Poly(U) RNA
(Elsevier, 1998)
Grb2 is an adaptor molecule comprising one Src homology (SH) 2 and two SH3 domains. This protein has a natural isoform named Grb3-3 with a deletion within the SH2 domain. Numerous evidence points to a functional connection ...

In vivo selection of porin-deficient mutants of Klebsiella pneumoniae with increased resistance to cefoxitin and expanded-spectrum cephalosporins
(American Society for Microbiology, 1996-02-01)
Four Klebsiella pneumoniae isolates (LB1, LB2, LB3, and LB4) with increased antimicrobial resistance were obtained from the same patient. The four isolates were indistinguishable in biotype, plasmid content, lipopolysaccharide, ...

Comparison of broth microdilution and E-test for susceptibility testing of Neisseria meningitidis
(American Society for Microbiology, 1996)
The susceptibilities of 54 clinical isolates of Neisseria meningitidis to penicillin, cefotaxime, ceftriaxone, cefepime, imipenem, ciprofloxacin, chloramphenicol, and rifampin were determined by the microdilution method ...
