A Restriction Analysis of Klebsiella Pneumoniae Phage SBS
<p>A Klebsiella phage was isolated from the San Bernardino sewage and its physiochemical properties analyzed. The present study found the density of the phage to be 1.44 g/ml, the burst size to be 10, and the phage had a latent period of 20-25 minutes. The DNA was found to be double stranded and …

Investigations of Carbapenem-resistant Klebsiella species and associated clinical considerations
… the last decade. Enterobacteriaceae, especially Klebsiella spp., have acquired resistance to quinolones, aminoglycosides, cephalosporins and carbapenems. Resistance to β-lactams is mediated via extended-spectrum β-lactamases, AmpC type β-lactamases and carbapenemases combined with porin loss. …

Chemical and spectroscopic studies of the capsular polysaccharides of some Klebsiella serotypes
… produced by strains of the bacterial genus Klebsiella, the capsular material of serotype K71 has been investigated, and that of serotypes K36 and K64 re-examined, by novel enzymic and spectroscopic methods. The cultivation and employment of bacteriophages which are capable of cleaving (by …

Structural analysis of capsular polysaccharides produced by some emerging Klebsiella pneumoniae serotypes
Klebsiella pneumoniae (K. pneumoniae), a Gram-negative pathogenic bacterium, is a leading cause of neonatal sepsis in low- and middle-income countries (LMICs). Due to rapidly increasing anti-microbial resistance (AMR), it has been ranked among the “critical-priority 1” pathogens to human health by …

Exploring the Polyclonal Antibody Responses Induced by Klebsiella pneumoniae Derived Outer-Membrane Vesicles
… are Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter spp. Of these, Klebsiella pneumoniae stands out due to its vast genomic diversity with only a small percentage of the genome being dedicated to the core genes, …

Identification and characterisation of cephalosporins and carbapenem-resistant Klebsiella pneumoniae isolates from Misrata, Libya
Background: Extended-spectrum beta-lactamase-producing (ESBL) and carbapenemaseproducing Gram-negative bacilli showing resistance to cephalosporins and carbapenems respectively, have been reported from several countries globally and recently among Libyan combatants who have been transferred to …

Disentangling bacterial virulence mechanisms: Klebsiella pneumoniae targets post-translational modifications (PTMs) to manipulate innate immunity
Klebsiella pneumoniae is a Gram-negative, multidrug-resistant (MDR) bacteria, causing nosocomial pneumonia, urinary tract infections (UTIs) and sepsis. Klebsiella’s subversion of the host immune response is critical for infection. Therefore, Klebsiella employs a range of novel mechanisms, including …

Molecular Studies of KpnAI and KpnBI R-M Systems : in KLEBSIELLA PNEUMONIAE M5a1 and GM236
… and <em>Kpn</em>Bl, were recognized in <em>Klebsiella pneumoniae</em> strains M5al and GM236, respectively. In this project, four <em>hsdR</em><sub>KpnAI</sub> clones (pNLA1 to pNLA4) were obtained by using an endonuclease expression-selection method. The <em>hsdR</em><sub>KpnAI</sub> gene …

Regulation of blaFOX-5b Expression Within Two Different Genetic Backgrounds: Klebsiella pneumoniae and Escherichia coli
Klebsiella pneumoniae and Escherichia coli are major nosocomial pathogens. A clinical isolate of K.pneumoniae and E. coli were found to produce a novel plasmid-encoded ampC P-lactamase gene, blaFOX-5b- These isolates conferred high level resistance to a broad spectrum of antibiotics, including …

Structural studies of the capsular polysaccharides from some strains of Klebsiella and Cryptococcus neoformans micro-organisms
… of anomeric linkages. The polysaccharides from Klebsiella K4 and X.pnev.moniae ( oxytoca variant) have been shovm to have linear tetra- and pentasaccharide repeating units respectively, while the structures of those from serotypes K27 and K64 have been found to be more complex, consisting of …

Klebsiella pneumoniae bloodstream infections in hospitalised children at Red Cross War Memorial Children's Hospital : 2006 - 2011
Background: Klebsiella pneumoniae (KP) is a significant paediatric bloodstream pathogen in children. There is little data about KP in South African children. The focus for the present study was to address this knowledge gap. Methods: This study addressed a retrospective case notes review on …

Epidemiological Typing and Mechanisms of Antibiotic Resistance in Clinically Relevant Klebsiella Pneumoniae Isolated at St. Marina University Hospital – Varna // Епидемиологично типизиране и механизми на антибиотична резистентност в клинично значими Klebsiella pneumoniae, изолирани в УМБАЛ „Света Марина“, Варна
… към бета-лактами и хинолони при клинично значими Klebsiella pneumoniае, изолирани от пациенти, хоспитализирани в УМБАЛ „Света Марина“ - гр. Варна в периода 2014 - 2017г. и да се определи клоналната свързаност на изолатите. Анализът на резултатите, получени в нашите проучвания и сравняването им с …

The Effect of O Antigen Loss on the Protein Composition and Inflammatory Response Elicited by Klebsiella pneumoniae
Klebsiella pneumoniae is a Gram-negative pathogen associated with numerous infections. Like all Gram-negative bacteria, K. pneumoniae naturally release outer membrane vesicles (OMVs) during all stages of cellular growth. OMVs are composed of the outer membrane components such as lipopolysaccharide …

Regulation of nitrogen fixation in <i>Klebsiella pneumoniae</i>: The role of Fnr in oxygen signal-transduction
In Klebsiella pneumoniae wird die Aktivität des Transkriptionsaktivators NifA durch NifL in Abhängigkeit von gebundenem Stickstoff und molekularem Sauerstoff geregelt. NifL, ein Flavoprotein, das redox-sensitiv ist, scheint, das Sauerstoffsignal über eine Konformationsänderung auf NifA zu …
