This study aimed to determine the prevalence of fecal carriage of extended spectrum β-lactamase (ESBL) and/or plasmidic AmpC β-lactamase (pAmpC) producing Escherichia coli among dogs (n=428) in Turkey. Polymerase chain reaction (PCR) and sequencing were used to characterize genes encoding β-lactamase and plasmid mediated quinolone resistance (PMQR). Antimicrobial susceptibility testing and PCRs...

Hemoglobin E-Saskatoon (b22-Glu->Lys) was first described by Vella et al. in a Canadian woman of mixed Scotish and Dutch origin and ever since the variant has been found in Greece, Scotland, Spain and Turkey. Hb E-Saskatoon seems to be an innocuous variant but there are not any available data concerning the association of haemoglobin E-Saskatoon with other haemoglobinopathies. Few published dat...

The extent to which individual juvenile fish occupy specific sites is largely unknown. This complicates efforts to identify optimum habitats and habitat-specific information such as growth and mortality rates which, in turn, can influence recruitment success. Using tag–recapture information, we examined movements and growth of juvenile tautog (Tautoga onitis [L.]) and cunner (Tautogolabrus adsp...

The primary in vitro antibody response to the type 2 antigen, trinitrophenyl (TNP)-Ficoll, is controlled by two complementing loci in the H-2 region of the mouse major histocompatibility complex (MHC). High responder alleles at both loci are necessary for a high responder phenotype. Previous studies mapped one locus of control to the I-A subregion. In this report we demonstrate by recombinant a...

INTRODUCTION Performance variation among PCR systems in detecting Toxoplasma gondii has been extensively reported and associated with target genes, primer composition, amplification parameters, treatment during pregnancy, host genetic susceptibility and genotypes of different parasites according to geographical characteristics. PATIENTS A total of 467 amniotic fluid samples from T. gondii IgM...

A genetic locus encoding erythritol uptake and catabolism genes was identified in Rhizobium leguminosarum bv. viciae, and shown to be plasmid encoded in a wide range of R. leguminosarum strains. A Tn5-B22 mutant (19B-3) unable to grow on erythritol was isolated from a mutant library of R. leguminosarum strain VF39SM. The mutated gene eryF was cloned and partially sequenced, and determined to ha...

To the Editor: 1 work at an overseas American institution, and there are extended delays in receipt of journals by our medical library. So, it was only a few days ago that I saw the article entitled “Weak Association between HLA-B27 and the Spondylarthropies in Lebanon,” which was published in the February 1997 issue of Arthritis & Rheumatism (1). I would like to draw the attention of the Leban...
