In an accompanying report, we showed that viridans group streptococci may prevent methicillin-resistant Staphylococcus aureus (MRSA) colonization of the oral cavities of newborns. In the present study, we investigated the mechanism of prevention in vitro. Most viridans group streptococci had bacteriocin-like activity and killed MRSA, Burkholderia cepacia, Enterobacter aerogenes, and Pseudomonas...
Methicillin resistant Staphylococcus aureus (MRSA) is a well known superbug commonly responsible for wound-related infections and most ominously for its lifethreatening conditions. The MRSA infections are great medical challenges in diabetic patients, especially causing ulcer foot infections and related complications which might lead to amputation and ultimately to death. The alarming increase ...
We used daptomycin plus antistaphylococcal β-lactams (ASBL) to clear refractory MRSA bacteremia. In vitro studies showed enhanced daptomycin bactericidal activity, increased membrane daptomycin binding, and decrease in positive surface charge induced by ASBLs against daptomycin nonsusceptible MRSA. Addition of ASBLs to daptomycin may be of benefit in refractory MRSA bacteremia. (Although the of...
The purpose of this study was to determine the antibacterial activity of ten essential oils. The ten essential oils were tested on MRSA and MSSA from hospital patients using the disk diffusion (Kirby Bauer) method. Based on this study, all ten oils showed higher effectiveness inhibiting MRSA and MSSA growth than vancomycin, which is the currently used standard for treatment. Essential oils coul...
Infections caused by hard-to-treat methicillin-resistant Staphylococcus aureus (MRSA) are a serious global public-health concern, as MRSA has become broadly resistant to many classes of antibiotics. We disclose herein the discovery of a new class of non-β-lactam antibiotics, the oxadiazoles, which inhibit penicillin-binding protein 2a (PBP2a) of MRSA. The oxadiazoles show bactericidal activity ...
In this study, we report the antibacterial activities of six polyphenols (i.e., luteolin, quercetin, scutellarin, apigenin, chlorogenic acid, and resveratrol) against 29 clinical isolates of methicillin-resistant Staphylococcus aureus (MRSA), and in vitro antibacterial activities of two-drug combinations. All of the MRSA strains evaluated were clinical isolates from patients with MRSA bacteremi...
The aim of the present study was to evaluate the antagonistic activity of marine Streptomyces sp. VITBRK1 against Methicillin resistance Staphylococcus aures (MRSA) and vancomycin-resistant Enterococci (VRE). Drug resistance by Bacterial pathogens do exhibit significant tolerance to standard antimicrobials during infections and drug resistance currently a growing problem worldwide. A total of 1...
Abstract 205 isolates of actinomycetes bacteria were isolated from soil samples collected Satun province, Thailand. To have more chances to get diverse groups bacteria, treated using three different methods before inoculated on two selective media, humic acid-vitamin agar and coal vitamin agar. After months incubation at 30°C, all typically characteristic colonies picked purified then tested fo...
OBJECTIVES Bactericidal activity depends on antibiotic-bacteria couples, resistance phenotype and theoretically on protein binding. This work explores the influence of protein binding on the bactericidal activity of two antibiotics, daptomycin versus vancomycin, that exhibit, respectively, different C(max) (56 versus 25.5 mg/L), protein binding (91.7% versus 36.9%) and thus theoretical free-dru...
BACKGROUND HIV-infected persons have increased risk of MRSA colonization and skin and soft-tissue infections (SSTI). However, no large clinical trial has examined the utility of decolonization procedures in reducing MRSA colonization or infection among community-dwelling HIV-infected persons. METHODS 550 HIV-infected adults at four geographically diverse US military HIV clinics were prospecti...
