Analysis of the length distribution of murein glycan strands inftsZandftsImutants ofE. coli [PDF]

open access: yesFEMS Microbiology Letters, 1998
The chain length distribution of murein glycan strands was analyzed in wild-type cells and in cells in which preseptal and/or septal murein synthesis was prevented in ftsZ84 and ftsI36 mutants of E. coli. This revealed a significant change in glycan chain lengths in newly synthesized murein associated with inactivation of the ftsZ gene product but not ...

Polymorphism of ftsI gene in Haemophilus influenzae and emergence of cefotaxime resistance in two Tunisian hospitals

open access: yesNew Microbes and New Infections, 2020
The decreased affinity to β-lactams in Haemophilus influenzae is usually caused by specific alterations in penicillin-binding protein 3 due to varieties of substitutions in ftsI gene. This study aimed to characterize the polymorphism of ftsI gene in 19 H.

Mutant ftsI genes in the emergence of penicillin-binding proteinmediated β-lactam resistance in Haemophilus influenzae in Norway [PDF]

open access: yesClinical Microbiology and Infection, 2010
The most important mechanism for beta-lactam resistance in beta-lactamase-negative ampicillin-resistant (BLNAR) isolates of Haemophilus influenzae is the alteration of penicillin-binding protein 3 (PBP3) as a result of ftsI gene mutations. The present study aimed to map PBP3 alterations and to determine the correlation to beta-lactam resistance in ...

Efficacy of Simulated Cefditoren versus Amoxicillin-Clavulanate Free Concentrations in Countering Intrastrain ftsI Gene Diffusion in Haemophilus influenzae [PDF]

open access: yesAntimicrobial Agents and Chemotherapy, 2011
ABSTRACT This study explores the effects of cefditoren (CDN) versus amoxicillin-clavulanic acid (AMC) on the evolution (within a single strain) of total and recombined populations derived from intrastrain ftsI gene diffusion in β-lactamase-positive (BL + ) and β-lactamase-negative ...

Numerical study on the performance of pintle controlled solid rocket motor based on fluid-thermal-structure interaction [PDF]

open access: yesCase Studies in Thermal Engineering
To accurately predict the performance of pintle controlled solid rocket motors (PCSRM), a fluid-thermal-structure interaction (FTSI) numerical model is developed. First, by comparing the FTSI method, conventional numerical method, and empirical formulas,

Molecular epidemiology of nontypeable Haemophilus influenzae causing community-acquired pneumonia in adults. [PDF]

open access: yesPLoS ONE, 2013
Nontypeable Haemophilus influenzae (NTHi) is an opportunistic pathogen which causes a variety of respiratory infections. The objectives of the study were to determine its antimicrobial susceptibility, to characterize the β-lactam resistance, and to ...

Revisiting mutational resistance to ampicillin and cefotaxime in Haemophilus influenzae [PDF]

open access: yesGenome Medicine
Background Haemophilus influenzae is an opportunistic bacterial pathogen that can cause severe respiratory tract and invasive infections. The emergence of β-lactamase-negative ampicillin-resistant (BLNAR) strains and unclear correlations between ...
