Application

Daptomycin has been studied as a potential therapy for Streptococcus pneumoniae infections. It has also been used to study the impact of sarA on daptomycin susceptibility of Staphylococcus aureus.

Biochem/physiol Actions

Daptomycin is a cyclic lipopeptide antibiotic. isolated from Streptomyces sp. It is effective against Gram-positive bacteria. It disrupts the plasma membrane causes rapid depolarization and inhibits the synthesis of protein, RNA and DNA. It is potent against Staphylococcus aureus infections, including MRSA (methicillin-resistant Staphylococcus aureus).

Mutation acquisition is a major mechanism of bacterial antibiotic resistance that remains insufficiently characterised. Here we present RM-seq, a new amplicon-based deep sequencing workflow based on a molecular barcoding technique adapted from Low Error Amplicon sequencing (LEA-seq). RM-seq allows detection

Increased evolution of multidrug resistant pathogens necessitates the development of multifunctional antimicrobials. There is a perceived need for developing new antimicrobials that can interfere with acute inflammation after bacterial infections. Here, we investigated the therapeutic potential of linear polyethylenimine (LPEI)

A spectrum of pneumococci with varying susceptibilities to beta-lactams, macrolides and quinolones was tested for susceptibility to nine antibiotics, including the novel lipopeptide daptomycin. Daptomycin was active against all strains (MIC range </=0.5 mg/L; MIC(50) 0.125 mg/L; MIC(90) 0.25 mg/L).

Studies have suggested that Cutibacterium acnes (formerly known as Propionibacterium) is the most frequently isolated pathogen after shoulder arthroplasty. To address the burden of periprosthetic joint infections associated with this pathogen, new prevention methods are needed. Tyrosol has a promising

Several studies have reported that daptomycin induced artificial prolongation of prothrombin time (PT) in some test reagents, particularly in warfarin users. However, it remains unknown whether the artificial prolongation can be affected by coagulation abnormalities other than the use of
