Genome Sequence of Klebsiella pneumoniae KpQ3, a DHA-1 β-Lactamase-Producing Nosocomial Isolate.
2012
ABSTRACT Klebsiella pneumoniae KpQ3 is a multidrug-resistant isolate obtained from a blood culture of a patient in a burn unit in the Hospital Universitario La Paz (Madrid, Spain) in 2008. The genome contains multiple antibiotic resistance genes, including a plasmid-mediated DHA-1 cephalosporinase gene.
COVID-19 Pandemic: Prevention and protection measures to be adopted at the workplace
2020
Introduction: SARS-CoV-2, identified in Wuhan, China, for the first time in December 2019, is a new viral strain, which has not been previously identified in humans; it can be transmitted both by air and via direct and indirect contact; however, the most frequent way it spreads is via droplets. Like the other viruses belonging to the same family of coronaviruses, it can cause from mild flu-like symptoms, such as cold, sore throat, cough and fever, to more severe ones such as pneumonia and breathing difficulties, and it can even lead to death. Since no effective specific drug therapy has been found yet, nor any vaccine capable of limiting the spread of this pathogen, it is important for way…
Antimikrobo līdzekļu menedžments stacionārā pnemonijas pacientiem
2019
Bakalaura darbs „Antimikrobo līdzekļu menedžments stacionārā pneimonijas pacientiem”. Tēmas aktualitāti nosaka elpošanas sistēmas saslimšanas gadījumu skaita palielināšanās, ar to saistīto antimikrobo līdzekļu lietošanas biežuma pieaugums un rezistento mikroorganismu attīstība. Darba mērķis ir noskaidrot antimikrobo līdzekļu menedžmenta realizāciju stacionārā pneimonijas pacientiem. Pētniecības metode – kvalitatīvā, instruments - intervija. Pētniecības jautājums: “Kā tiek realizēts antimikrobo līdzekļu terapijas menedžments pneimonijas pacientiem Intensīvās terapijas klīnikā?” Pētījuma rezultāti apliecina, ka Intensīvās terapijas klīnikā praktizējošās māsas izprot un īsteno antimikrobo līdz…
Looking for the best immune-checkpoint inhibitor in pre-treated NSCLC patients: An indirect comparison between nivolumab, pembrolizumab and atezolizu…
2017
Immune-checkpoint inhibitors represent the new standard of care in patients with advanced NSCLC who progressed after first-line treatment. This work aim to assess any difference in both efficacy and safety profiles among Nivolumab, Pembrolizumab and Atezolizumab in pre-treated NSCLC patients. Randomized clinical trials comparing immune-checkpoint inhibitor versus docetaxel in pre-treated patients with advanced NSCLC were included and direct comparison meta-analysis of selected trials have been performed. Subsequently the summary estimates of Nivolumab, Pembrolizumab and Atezolizumab emerging from the direct meta-analysis were selected to provide the pooled estimates of hazard ratio (HR) and…
Streptococcus pneumoniae sortāzes A inhibitoru atlase multirezistentu patogēnu izraisīto infekcijas slimību terapijai
2019
Darba mērķis ir atrast jaunas novatoriskas vielas, kas inhibē Grampozitīvās baktērijas Streptococcus pneumoniae transpeptidāzi sortāzi A. Šo inhibitoru atlasei tika izmantota rekombinanta S.pneumoniae sortāzes A katalītisko domēnu kodējoša konstrukcija bez N terminālā reģiona. Šāda rekombinanta transpeptidāze tika ekspresēta E.coli ekspresijas sistēmā un sintezētais proteīns izrādījās šķīstošs. Pēc attīrīšanas sortāze tika izmantota inhibitoru atlasei, izmantojot skrīningu, kas balstās uz fluorescences rezonanses enerģijas pārnesi (FRET). Pavisam tika pārbaudīti 966 potenciāli inhibitori savienojumi, no kuriem tālākām pārbaudēm tika atlasīti trīs labākie, kuri inhibēja IC50 testā izmantotās…
Pneumococcal HxxHxH triad – Copper(II) interactions – How important is the ‘x’?
2019
Abstract PhtA, a Streptococcus pneumoniae polyhistidine triad protein, which contributes to virulence by interacting with components of the immune system, by being involved in adherence of bacteria and in Zn(II) uptake, contains five copies of the HxxHxH sequence. Since this motif is also present in numerous Cu(II) binding proteins, we decided to focus on the bioinorganic chemistry of copper(II) with three of such PhtA repeats, in order to understand which of the PhtA triads binds Cu(II) with the highest affinity and explain if Cu(II) would be able to outcompete Zn(II) from its native binding site under physiological metal concentrations.
A search for beta-lactamase in chlamydiae, mycoplasmas, planctomycetes, and cyanelles: bacteria and bacterial descendants at different phylogenetic p…
2000
Bacteria from different phylogenetic positions such as chlamydiae, mycoplasmas, planctomycetes and also endosymbiotic murein-containing cyanelles were investigated for the production of beta-lactamases. No beta-lactamase activity was found in bacteria lacking murein such as Chlamydia pneumoniae, Mycoplasma pneumoniae, Pirellula marina and Planctomyces maris. In the murein-containing cyanelles of Cyanophora paradoxa no beta-lactamase activity could be detected.

Variety of size and form of GRM2 bacterial microcompartment particles
2021
Bacterial microcompartments (BMCs) are bacterial organelles involved in enzymatic processes, such as carbon fixation, choline, ethanolamine and propanediol degradation, and others. Formed of a semi‐permeable protein shell and an enzymatic core, they can enhance enzyme performance and protect the cell from harmful intermediates. With the ability to encapsulate non‐native enzymes, BMCs show high potential for applied use. For this goal, a detailed look into shell form variability is significant to predict shell adaptability. Here we present four novel 3D cryo‐EM maps of recombinant Klebsiella pneumoniae GRM2 BMC shell particles with the resolution in range of 9 to 22 Å and nine novel 2D class…
