Competition among auctioneers [PDF]

open access: yes, 2001
In this paper, we analyse a multistage game of competition among auctioneers. In a first stage, auctioneers commit to some publicly announced reserve prices, and in a second stage, bidders choose to participate in one of the auctions.

Novel SHV-Derived Extended-Spectrum β-Lactamase, SHV-57, That Confers Resistance to Ceftazidime but Not Cefazolin [PDF]

open access: yesAntimicrobial Agents and Chemotherapy, 2005
ABSTRACT A new SHV-derived extended-spectrum β-lactamase, SHV-57, that confers high-level resistance to ceftazidime but not cefotaxime or cefazolin was identified from a national surveillance study conducted in Taiwan in 1998.

Determination of SHV-2, SHV-5, SHV-12 and CTX-M-3 extended-spectrum beta-lactamases in clinical enterobacteriaceae isolates: Scientific letter [Enterobacteriaceae Klinik İzolatlari{dotless}nda SHV-2, SHV-5, SHV-12 VE CTX-M-3 Genişlemiş Spektrumlu Beta-Laktamazlari{dotless}n Saptanmasi{dotless}]

open access: yesTurkiye Klinikleri Journal of Medical Sciences, 2019
Extended spectrum beta-lactamases (ESBLs) are common in our country as well as in the world. However, data about the molecular types of these enzymes are lacking in Turkey. ESBLs were initially determined commonly as TEM and SHV derivatives, but in recent years CTX-M enzymes have become more dominant.

Enzymatic analysis of the effect of naturally occurring Leu138Pro mutation identified in SHV β-lactamase on hydrolysis of penicillin and ampicillin

open access: yesBMC Microbiology, 2011
Background The aim of this study was to analyze the significance of leucine to proline substitution at position 138(Leu138Pro) on the hydrolysis of penicillin and ampicillin that we identified in the blaSHV gene of clinical Escherichia coli swine isolate.

Molecular Cloning of the Shv-1  -Lactamase Gene and Construction of an Shv-1 Hybridization Probe [PDF]

open access: yesMicrobiology, 1988
We have cloned the Shv-1 beta-lactamase gene from the R1010 plasmid into pACYC184. By subcloning and transposon mutagenesis we have localized the gene to a 1.6 kb BscI-SalI fragment of R1010, which is present in the recombinant plasmid pUB8. A 900 bp PstI fragment of pUB8 was shown to be a specific hybridization probe by testing against plasmids which ...

Prevalence and molecular characterization of extended spectrum beta-Lactamases-producing uropathogenic Escherichia coli isolated in Zakho, Iraq [PDF]

open access: yesJournal of Microbiology and Infectious Diseases, 2017
Objectives: Uropathogenic Escherichia coli are the most important group of microorganisms responsible for urinary tract infection. A high percentage of uropathogenic E. coli over the world are detected to be ESBLs producers, which is now a problem that
