Concurrent outbreaks of extended-spectrum beta-lactamase-producing organisms of the family Enterobacteriaceae in a Warsaw hospital.
The increasing use of broader-spectrum cephalosporins in the first half of the 1990s has become one of the major factors responsible for the high rate of selection of extended-spectrum beta-lactamaseExpand
Involvement of genetic factors in the response to a variable-dosing ranibizumab treatment regimen for age-related macular degeneration
Visual acuity did not improve during the study in patients homozygous for ARMS2 69S, despite a decrease in CSRT, and multiple regression analysis revealed a significant impact of 69S on the change in BCVA. Expand
A Novel Complex Mutant β-Lactamase, TEM-68, Identified in a Klebsiella pneumoniae Isolate from an Outbreak of Extended-Spectrum β-Lactamase-Producing Klebsiellae
TEM-68 was shown to be a novel complex mutant TEM β-lactamase (CMT-2) which combines strong ESBL activity with relatively weak IR activity and, when expressed in K. pneumoniae, is able to confer high-level resistance to a wide variety of β- lactams, including inhibitor combinations. Expand
Studies on the effects of probiotic Lactobacillus mixture given orally on vaginal and rectal colonization and on parameters of vaginal health in women with intermediate vaginal flora.
Oral application of the combination of the three probiotic strains derived from vaginal microbiota of healthy woman with high adherence abilities to both vaginal and colonic epithelium in vitro shows that both individual strains and their mixture can colonize vagina for some weeks. Expand
Sulfate and thiosulfate transport in Escherichia coli K-12: identification of a gene encoding a novel protein involved in thiosulfate binding
The sequence of 1,973 nucleotides encompassing the region at and directly adjacent to the CysB-dependent promoter controlling expression and synthesis of the sulfate-thiosulfate transport system of Escherichia coli has been determined and the deduced amino acid sequence of the cysP polypeptide indicates the presence of a signal peptide.

Outbreak of Ceftazidime-Resistant Klebsiella pneumoniae in a Pediatric Hospital in Warsaw, Poland: Clonal Spread of the TEM-47 Extended-Spectrum β-Lactamase (ESBL)-Producing Strain and Transfer of a
The data presented here exemplify the complexity of the epidemiological situation concerning ESBL producers typical for large Polish hospitals, in which no ESBL-monitoring programs were in place prior to 1995. Expand
Virus‐Like Particles: Models for Assembly Studies and Foreign Epitope Carriers
The chapter outlines the recent achievements in two important fields of research brought about by the availability of VLPs produced in a foreign host, and the requirements for VLP assembly and the use of VLP as carriers for foreign epitopes. Expand
Cloning and sequencing of full-length cDNAs of RNA1 and RNA2 of a Tomato black ring virus isolate from Poland
Full-length cDNA clones corresponding to the RNA1 and RNA2 of the Polish isolate MJ of Tomato black ring virus were obtained using a direct recombination strategy in yeast, and their complete nucleotide sequences were established. Expand
Nucleotide sequence of RNA of a Polish isolate of potato leafroll luteovirus.
The nucleotide sequence of the genomic RNA of a Polish isolate of a potato leafroll virus was determined. Some variations between the determined sequences were observed. A comparison of the frequencyExpand
Construction of cys:lac gene fusions in Escherichia coli and their use in the isolation of constitutive cysBc mutants.
Operon fusions of the lacZ gene to two different genes of the cysteine regulon controlled by the cysB regulatory protein were isolated and used for selection of cys B constitutive mutants. Expand
