Bacteria

  • (13) The most commonly encountered organisms were aerobic bacteria (91%), anaerobes (74%), and fungi (48%).
  • (14) Resistance to antibiotics have been detected in food poisoning bacteria, namely Salmonella typhimurium, Staphylococcus aureus and Clostridium perfringens.
  • (15) Bacteria can stop or lessen antibodies synthesis process.
  • (16) Among the agents triggering such an infection Chlamydia (30.9% of the cases of non-gonorrhoic urethritis), as well as mycoplasma, ureaplasma, anaerobic bacteria and herpes simplex viruses have gained particular significance.
  • (17) Mu does not grow lytically in or kill him bacteria but can lysogenize such hosts.
  • (18) Tunnel-like formations at different depths of the oral epithelium contained higher numbers of bacteria than those seen on the adjacent oral surface.
  • (19) The cells were taken from cultures in low-density balanced exponential growth, and the experiments were performed quickly so that the bacteria were in a uniform physiological state at the time of measurement.
  • (20) Subgingival plaque was sampled and the presence or absence of the above mentioned bacteria assessed with BANA reagent cards (Perio Scan).

Prokaryotic


Definition:

Example Sentences:

  • (1) Of all the claims that have been made over the years, those reporting transfers between eukaryotes and prokaryotes are the most controversial.
  • (2) From the decreased alignment at the N-terminus and the presence of additional residues compared with bacterial phosphorylases, we conclude that the regulatory sequences that also carry the phosphorylation site in the muscle enzyme were joined to a presumed ancestral precursor gene by gene fusion after separation of the eukaryotic and prokaryotic lines of descent.
  • (3) In addition, most of the major topoisomerase II cleavage sites closely corresponded to naked DNA hypersensitive sites for the prokaryotic enzyme, micrococcal nuclease.
  • (4) The cytoplasm and the periplasma of the gram-negative facultative photosynthetic bacterium Rhodopseudomonas sphaeroides contain phospholipid transfer proteins; these seem to be involved in the biosynthesis of prokaryotic membranes.
  • (5) Chaperonins (Cpn) are implicated in the folding and assembly of multimeric proteins in plastids and mitochondria of eukaryotes and in prokaryotes.
  • (6) Novobiocin, an inhibitor of gyrase-induced DNA supercoiling and DNA replication in prokaryotes, inhibited the incorporation of DNA precursors into DNA in both intact and permeable Chinese hamster ovary cells; much higher concentrations were required for permeable cells, in which no new replicons were initiated.
  • (7) No increase in the specific activity of either chromosomal or plasmid-borne prokaryotic genes has been observed.
  • (8) Subgenomic fragments of cloned infectious coxsackievirus B3 (CVB3) cDNA up to the size of the complete coding sequence of the viral polyprotein were inserted into the prokaryotic expression vector pPLc24 and expressed in Escherichia coli.
  • (9) Insertion of the trimer into several expression vectors efficiently prevented spurious expression of reporter genes resulting from transcriptional initiation in prokaryotic plasmid sequences in transfected mammalian cells.
  • (10) Prokaryotic and eukaryotic cells respond to a variety of stress conditions by increasing the synthesis of a family of proteins collectively known as heat-shock proteins (HSP).
  • (11) These results show that the prokaryotic denV gene can restore UV repair capabilities in vivo to CHO UV5 cells defective in repair of UV-induced damage.
  • (12) Pulsed field gel electrophoresis of the fragments that result from cleavage with endonucleases that cleave only a few times per genome should assist in the physical mapping of many prokaryotic genomes.
  • (13) The derived amino acid sequence of 562 residues shows a high degree of homology to the previously published GR sequences from human erythrocytes and from two prokaryotes: Escherichia coli and Pseudomonas aeruginosa.
  • (14) Cavalier-Smith (1981) has identified 22 characters that are universally present in eukaryotes but absent in prokaryotes.
  • (15) We have attempted to develop the studies initiated by Poindexter,Stove and Stanier, and Schmidt and Stanier (16, 17, 20) with the Caulobacter genus so that these bacteria can serve as a model system for prokaryotic differentiation.
  • (16) In prokaryotic cells, a dispersed labeling was noted over the cytoplasm and, in some cases, the aggregation of few gold particles suggested the presence of packed DNA fibrils.
  • (17) In addition, the far upstream element can increase expression of a prokaryotic chloramphenicol acetyl transferase (CAT) gene under control of the simian virus 40 (SV40) early promotor, indicating that the ability to influence transcription is not confined to the gene with which it is normally associated.
  • (18) The antibiotic rifampicin, which in prokaryotes inhibits the initiation of RNA synthesis but not the completion of nascent strands, was used to explore tRNA gene transcriptional organization in Escherichia coli.
  • (19) Metabolic pathways of prokaryotes are more biochemically diverse than is generally recognized.
  • (20) We propose that REP sequences may be a prokaryotic equivalent of 'selfish DNA' and that gene conversion may play a role in the evolution and maintenance of REP sequences.
