Following sexual transmission, Chlamydia trachomatis specifically targets genital tract epithelial cells. Because epithelial cells are readily recognized by CD8+ T cells, the response of CD8+ T cells to Chlamydia infection has been explored in a number of studies. It has been shown that CD8+ T cells are present in the genital tracts of mice following C. trachomatis infection, but the specificit...

INTRODUCTION The incidence of multidrug resistant microorganisms worldwide is increasing. The aim of the study was to present institutional experience with the multidrug resistant microorganism colonization patterns observed in children with congenital heart diseases hospitalized in a hybrid pediatric cardiac surgery center. MATERIAL AND METHODS Microbiological samples were routinely collecte...

Next generation GPS receivers will take advantage of Spatial processing from a Controlled Reception Pattern Antenna (CRPA) and Ultra-Tightly-Coupled (UTC) and Tightly–Coupled GPS/inertial signal processing to improve their robustness to interference and their performance in a multipath environment. This introduces the potential for failure modes to be introduced into the GPS solution from the S...

The ongoing spread of antimicrobial resistance has complicated the treatment bacterial hospital-acquired pneumonia (HAP) and ventilator-associated (VAP). Gram-negative pathogens, especially those with multidrug-resistant profiles, including Escherichia coli, Klebsiella pneumoniae, Enterobacter </ns4:bold...

Pseudomonas aeruginosa (P. aeruginosa) is ubiquitous in nature, and may be a causative agent severe, life-threatening infections. In &gt;60% of cases, β-lactam antibiotics are used the therapy P. infections, therefore emergence carbapenem-resistant (CRPA) significant clinical concern. this study, phenotypic methods were to characterize fifty-four (n = 54) isolates, which included based on their s...

Correlation effects play an important role in the electronic structure of half-metallic (HM) magnets. In particular, they give rise to nonquasiparticle states above (or below) the Fermi energy at finite temperatures that reduce the spin polarization and, as a consequence, the efficiency of spintronics devices. Employing the constrained random-phase approximation (cRPA) within the full-potential...

BACKGROUND AND PURPOSE Chlamydia spp. are important pathogens of humans and animals that cause a wide range of acute and chronic infections. A persistence model has been developed in which Chlamydia spp. do not complete their developmental cycle, have significantly reduced infectivity for new host cells, and exhibit abnormal inclusion and reticulate body morphology. This study was performed to ...

Although Escherichia coli strain EC3132 possesses a chromosomally encoded sucrose metabolic pathway, its growth on low sucrose concentrations (5 mM) is unusually slow, with a doubling time of 20 h. In this report we describe the subcloning and further characterization of the corresponding csc genes and adjacent genes. The csc regulon comprises three genes for a sucrose permease, a fructokinase,...
