Pseudomonas aeruginosa, a vivid biofilm-producing bacterium, is considered dreadful opportunistic pathogen, and thus, management of biofilm-associated infections due to multidrug resistant strains by traditional drugs currently great concern. This study was aimed assess the impact trigonelline hydrochloride, pyridine alkaloid, on P. aeruginosa PAO1, in search an alternative therapeutant. The effect colony morphology motility studied along with its role biofilm expression virulence factors....
Breast cancer is considered as an increasing major life-threatening concern among the malignancies encountered globally in females. Traditional therapy far from satisfactory due to drug resistance and various side effects, thus a search for complementary/alternative medicines natural sources with lesser effects being emphasized. Andrographis paniculata, oriental, traditional medicinal herb commonly available Asian countries, has long history of treating variety diseases, such respiratory...
The study aims to explore the combinatorial effect of naringin with antibiotics, ciprofloxacin and tetracycline on Pseudomonas aeruginosa biofilms. antibiofilm efficacy selected treatment regimes against P. biofilm were quantified by crystal violet assay, MTT Congo red binding visualized confocal laser scanning microscopy electron microscopy. All assays reflected activities, however, performances antibiotics found be more significant. A significant reduction in swimming swarming motilities...
This study aimed to evaluate the effect of reserpine, a plant-derived indole-alkaloid, against Pseudomonas aeruginosa PAO1 biofilms. The anti-biofilm activity reserpine was evaluated by crystal violet staining, MTT assay, confocal laser scanning microscopy and electron microscopy. Reserpine effects were also assessed qRT-PCR quorum sensing (QS)-regulated genes biochemical quantification QS-mediated virulence factors pyocyanin, rhamnolipids, proteases elastases. reduced biofilm formation,...
A cadmium (8 mM) resistant Pseudomonas aeruginosa strain KUCd1 exhibiting high Cd accumulation under in vitro aerobic condition has been reported. The isolate showed a significant ability to remove more than 75% and 89% of the soluble during active growth phase from medium Cd-amended industrial wastewater supportive condition. Transmission electron microscopy (TEM) energy dispersive X-ray spectroscopy (EDXS) suggest presence cells mid-stationary phase. cell fractionation study revealed...
This Article deals with the toxicological study of synthesized CdO nanoparticles (NPs) on Escherichia coli . Characterization NPs was done by DLS, XRD, TEM, and AFM studies, average size revealed as 22 ± 3 nm. The showed bactericidal activity against E. coli. When were added at midlog phase growth, complete growth inhibitory concentration found 40 μg/mL. Bacterial cells changed morphological features to filamentous form increasing exposure time, thereafter resulted in...
Microbial enzymatic reduction of a toxic form chromium [Cr(VI)] has been considered as an effective method for bioremediation this metal. This study reports on the in vitro Cr(VI) using cell-free extracts from reducing Bacillus firmus KUCr1 strain. Chromium reductase was found to be constitutive and its activity observed both soluble cell fractions (S12 S150 membrane fraction (P150). The S12 optimal at 40 microM with enzyme concentration equivalent 0.493 mg protein/ml. Enzyme dependent NADH...
The present study endeavors to isolate a nickel (Ni)-resistant bacterial strain from an industrial waste–contaminated soil sample and characterize the with view identify it assess its ability remove Ni medium or detoxify it. final objective is use as agent bioremediate contamination. As outcome, Ni-resistant (KUNi1) had been isolated such that could tolerate maximum of 7.5 10 mM concentrations, depending on type used. also showed multimetal resistance. It was found be resistant zinc (Zn),...
The goal of this study was to evaluate the antibiofilm and antimicrobial activities Bacoside A, a formulation phytochemicals from Bacopa monnieri, against Staphylococcus aureus Pseudomonas aeruginosa, which are known form biofilms as one their virulence traits. effects A were tested using minimum inhibitory concentration bactericidal assays. cell membrane disruption assay performed find its possible target site. MTT assay, crystal violet microscopic studies assess activity. showed activity...
