  • Emerging Resistance of Gram Negative Pathogens in Community-Acquired Pneumonia. [Journal Article]
    Semin Respir Crit Care Med. 2020 Aug; 41(4):480-495.Amati F, Restrepo MI
  • In recent decades, there has been a growing interest about the role of gram negative bacteria in community-acquired pneumonia (CAP), especially Pseudomonas aeruginosa, Enterobacteriaceae, and Acinetobacter baumannii. The prevalence of these pathogens differs largely according to the local ecology and the geographical location. Identifying gram negative bacteria, and in particular resistant gram n…
  • Structural characterization of borneol dehydrogenase from Pseudomonas sp. TCU-HL1. [Journal Article]
    Acta Crystallogr F Struct Biol Commun. 2020 Jul 01; 76(Pt 7):309-313.Khine AA, Chen HP, … Ko TP
  • During the microbial degradation of borneol, a bicyclic plant monoterpene, it is first converted into camphor by borneol dehydrogenase (BDH) and then enters a known camphor-degradation pathway. Previously, a recombinant Pseudomonas BDH was found in inclusion bodies when expressed in Escherichia coli. After refolding, it was still unstable and was difficult to concentrate. Here, the protein-expres…
  • Transcriptome Analysis of Zygotic Induction During Conjugative Transfer of Plasmid RP4. [Journal Article]
    Front Microbiol. 2020; 11:1125.Miyakoshi M, Ohtsubo Y, … Tsuda M
  • Conjugative transfer of bacterial plasmid is one of the major mechanisms of horizontal gene transfer, which is mediated by direct contact between donor and recipient cells. Gene expression of a conjugative plasmid is tightly regulated mostly by plasmid-encoded transcriptional regulators, but it remains obscure how differently plasmid genes are expressed in each cell during the conjugation event. …
  • Recovery of aerobic gram-negative bacteria from the Copan Eswab transport system after long-term storage. [Journal Article]
    Diagn Microbiol Infect Dis. 2020 Jun 06; 98(1):115100.Tops SCM, Kolmus M, … Kolwijck E
  • We evaluated the Copan Eswab transport system for the quantitative recovery of Escherichia coli, Klebsiella pneumoniae, and Pseudomonas aeruginosa after 1, 2, 3, 5, and 7 days of storage at room and refrigerator temperatures, and 7 and 30 days of storage at -80 °C and -20 °C using mono- and polymicrobial samples. The study was based on Clinical and Laboratory Standards Institute (CLSI) M40-A2 sta…
  • Core Microbiota in Central Lung Cancer With Streptococcal Enrichment as a Possible Diagnostic Marker. [Journal Article]
    Arch Bronconeumol. 2020 Jun 30 [Online ahead of print]Bello S, Vengoechea JJ, … Del Campo R
  • CONCLUSIONS: The central lung cancer microbiome shows high levels of Streptococcus, and differs significantly in its composition from that of control subjects. Changes are not restricted to tumour tissue, and seem to be the consequence of microaspirations from the oral cavity. These findings could be useful in the screening and even diagnosis of this disease.
  • Efficacy of experimental phage therapies in livestock. [Journal Article]
    Anim Health Res Rev. 2020 Jun 19 [Online ahead of print]Dec M, Wernicki A, Urban-Chmiel R
  • Bacteriophages are the most abundant form of life on earth and are present everywhere. The total number of bacteriophages has been estimated to be 1032 virions. The main division of bacteriophages is based on the type of nucleic acid (DNA or RNA) and on the structure of the capsid. Due to the significant increase in the number of multi-drug-resistant bacteria, bacteriophages could be a useful too…
  • Osmotic stress induces gut microbiota community shift in fish. [Journal Article]
    Environ Microbiol. 2020 Jul 02 [Online ahead of print]Lai KP, Lin X, … Tse WKF
  • Alteration of the gut microbiota plays an important role in animal health and metabolic diseases. However, little is known with respect to the influence of environmental osmolality on the gut microbial community. The aim of the current study was to determine whether the reduction in salinity affects the gut microbiota and identify its potential role in salinity acclimation. Using Oryzias melastig…
