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.

Actions biochimiques/physiologiques

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).

Autres remarques

Keep container tightly closed in a dry and well-ventilated place.

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).

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)

Antibiotics continue to be the standard-of-care for bacterial vaginosis (BV), although recurrence rates are high. Vaginal probiotics may improve durability of BV treatment, although few probiotics for vaginal health contain Lactobacillus spp. that commonly colonize the lower female genital tract.
