(1) In vitro antibacterial activity of fusidic acid (FUC) in combination with cefotaxime (CTX), imipenem (IMP), gentamicin (GEN), amikacin (AKN), rifampin (RIF), fosfomycin (FOS), vancomycin, pefloxacin (PEF) was studied against 19 presumably pathogen meti-R Staphylococcus epidermidis strains.
(2) The activity of five cephalosporins has been studied with 80 coagulase-negative methicillin-resistant Staphylococcus strains (SCN meti-R) isolated from hospitalized patients.
(3) The presence of two transcription terminators located downstream from metY produces a small tRNAMetf2 precursor transcript, whereas an internal promoter situated between metY and the first open reading frame directs the transcription of only the protein-coding part of the operon.
(4) Diphtheria infection of the throat, nose, ears and skin was common in the North American Indian and Metis people, but rarely caused severe symptoms.
(5) We were unable to construct mutants deficient in both tRNA(f1Met) and tRNA(f2Met) by P1 phage-mediated transduction with the metY and metZ mutations.
(6) In three years, Corynebacterium diphtheriae was isolated from 1238 people, consisting of 820 North American Indians or Metis, 318 people of Caucasian origin, 97 Eskimos and 3 Asiatic Indians.
(7) A number of genes encoding proteins involved in transcription and translation are clustered between 68 and 69 minutes on the Escherichia coli genome map and are transcribed clockwise as two operons: the metY operon, containing metY, P15A, nusA, infB; and about a kilobase further downstream, the rpsO and pnp operon.
(8) The bactericidal activity of daptomycin was compared with that of vancomycin and of teicoplanin with regard to 54 Gram positive strains of bacteria: (S. aureus meti S and meti R; S. epidermidis meti S and meti R; E. faecalis, E. faecium, and Corynebacterium group JK).
(9) Some other additional polymorphic sites have been found in generally constant bands giving additional allelic systems, in metis families.
(10) Results show that in all cases cefamandole has the highest activity on SCN meti-R.
(11) Serum IgE levels and the prevalence of certain atopic diseases have been studied in 819 individuals in 176 white families living in central Saskatchewan and in 275 individuals in 58 Metis families living in northern Saskatchewan.
(12) The results indicate that P15B and P35 are expressed as part of the metY operon, but that some transcriptional read through into the rpsO operon also occurs, thereby, functionally linking the expression of these two complex systems.
(13) The metY-nusA-infB operon of Escherichia coli encodes functions involved in both transcription and translation.
(14) An analysis of red blood cells resistance has been conducted by exposing red corpuscles of zebu, Baoule and metis zebu x Baoule, to different saline concentrations.
(15) We also show that the metY locus of E. coli B is transcriptionally active.
(16) Moreover, the ampicillin-resistance marker of the pUC9 plasmid carrying metZ+ was not cured at 42 degrees C in host cells with the polAts and metY-metZ double mutations.
(17) We show that the metY locus which specifies tRNA(2fMet) in Escherichia coli K-12 specifies tRNA(1fMet) in E. coli B.
(18) The public health significance of the endemic infection of the North American Indian and Metis people is discussed.
(19) Multivariate methods are used to study differences among the French, the British and Native Indian (includes Metis and Eskimos) populations of Canada over three census periods from 1951 to 1971.
(20) The germs were mainly located in the respiratory track (Staphylococcus aureus meti-S (34%) and Hemophilus (29%)).
