Biofilm inhibition of Staphylococcus aureus by silver nanoparticles derived from Hellenia speciosa rhizome extract.

Staphylococcus aureus is the most common cause of serious health conditions because of the formation of biofilm, which lowers antibiotic efficacy and enhances infection transmission and tenacious behavior. This bacteria is a major threat to the worldwide healthcare system. Silver nanoparticles have strong antibacterial characteristics and emerged as a possible alternative.

Critical review on plant-derived quorum sensing signaling inhibitors in pseudomonas aeruginosa.

Pseudomonas aeruginosa, a biofilm-forming organism with complex quorum mechanisms (Las, Rhl, PQS, and IQS), poses an imminent danger to the healthcare sector and renders current treatment options for chemotherapy ineffectual. The pathogen's diverse pathogenicity, antibiotic resistance, and biofilms make it difficult to eradicate it effectively. Quorum sensing, a complex system reliant on cell density, controls P.

Optimization of quorum quenching mediated bacterial attenuation of root extract by response surface modelling through Box-Behnken approach.

The present study was intended to optimize the quorum sensing inhibitory action of root extract against . Factors such as bacterial density, frequency of administration and concentration of extract were analysed. Plant samples were collected from Thrissur District, Kerala, India.

Quorum sensing intervened bacterial signaling: Pursuit of its cognizance and repression.

Bacteria communicate within a system by means of a density dependent mechanism known as quorum sensing which regulate the metabolic and behavioral activities of a bacterial community. This sort of interaction occurs through a dialect of chemical signals called as autoinducers synthesized by bacteria. Bacterial quorum sensing occurs through various complex pathways depending upon specious diversity.

Virulence Factors and Anti Fungal Sensitivity Pattern of Candida Sp. Isolated from HIV and TB Patients.

The study comprised of 60 Candida spp., 50 isolates from HIV and TB positive individuals (immunocompromised) and 10 isolates from non-HIV and -TB patients (immunocompetent). Among the 60 Candidal isolates, 83.
