Treatment of tuberculosis in a region with high drug resistance: Outcomes, drug resistance amplification and re-infection [PDF]

open access: yes, 2011
Introduction: Emerging antituberculosis drug resistance is a serious threat for tuberculosis (TB) control, especially in Eastern European countries. Methods: We combined drug susceptibility results and molecular strain typing data with treatment outcome ...

Mutations inside rifampicin-resistance determining region of rpoB gene associated with rifampicin-resistance in Mycobacterium tuberculosis

open access: yesJournal of Infection and Public Health, 2018
Rifampicin (RIF) plays a pivotal role in the treatment of tuberculosis due to its bactericidal effects. Because the action of RIF is on rpoB gene encoding RNA polymerase β subunit, 95% of RIF resistant mutations are present in rpoB gene. The majority of the mutations in rpoB gene are found within an 81bp RIF-resistance determining region (RRDR ...

Genetic Transformation of Rifampicin Resistance in Lactobacillus acidophilus [PDF]

open access: yesMicrobiology, 1986
Lactobacillus acidophilus strain 100-33, originally isolated from swine faeces, was transformed to rifampicin resistance with DNA from spontaneous rifampicin-resistant mutants derived from it. Cells of the recipient strain were treated with lysozyme and mutanolysin, mixed with donor DNA and polyethylene glycol and grown on a regeneration medium ...

Survival of a potential bacterial biocontrol agent in the soil and its impact on microbial communities

open access: yesPest Management Science, EarlyView.
In soil microcosms, the candidate Bacillus persisted ≥6 months and caused modest community shifts whose transience and magnitude were soil dependent. Abstract BACKGROUND Sclerotinia sclerotiorum is a major crop pathogen commonly managed using fungicides.

In vitro emergence of rifampicin resistance in Propionibacterium acnes and molecular characterization of mutations in the rpoB gene [PDF]

open access: yes, 2017
Objectives Activity of rifampicin against Propionibacterium acnes biofilms was recently demonstrated, but rifampicin resistance has not yet been described in this organism. We investigated the in vitro emergence of rifampicin resistance in P.

Brain Pericytes and Wnt/β‐Catenin Signaling Induce Functional Blood–Brain Barrier Phenotype in Human iPSC‐Derived Model

open access: yesSmall Methods, EarlyView.
This study shows that human iPSC‐derived endothelial cells acquire a functional blood–brain barrier phenotype when co‐cultured with brain pericytes and stimulated with CHIR‐99021, a Wnt/β‐catenin activator. This model recapitulates key barrier properties, inflammatory responses, and transcriptomic features of the native human BBB, offering new ...

Low-cost rapid detection of rifampicin resistant tuberculosis using bacteriophage in Kampala, Uganda [PDF]

open access: yes, 2007
Background Resistance to anti-tuberculosis drugs is a serious public health problem. Multi-drug resistant tuberculosis (MDR-TB), defined as resistance to at least rifampicin and isoniazid, has been reported in all regions of the world. Current phenotypic

Overexpression of Escherichia coli yaiX Confers Multidrug Resistance and Enhances Virulence in the Silkworm Infection Model

open access: yesMicrobiology and Immunology, EarlyView.
ABSTRACT The emergence of bacteria with both antimicrobial resistance and high virulence has become a global health concern, underscoring the urgent need to elucidate the molecular basis underlying these traits. Here, we employed the silkworm (Bombyx mori) infection model, which is suitable for high‐throughput screening, together with an Escherichia ...
