It has been reported that penicillin-binding protein 4 (PBP4) activity decreases when a vancomycin-susceptible Staphylococcus aureus isolate is passaged in vitro to vancomycin resistance. We analyzed the PBP profiles of four vancomycin intermediately susceptible S. aureus (VISA) clinical isolates and found that PBP4 was undetectable in three isolates (HIP 5827, HIP 5836, and HIP 6297) and marke...

BACKGROUND Vancomycin has only rarely been implicated as a cause of thrombocytopenia, and there is only limited evidence that this complication is caused by immune mechanisms. We conducted a study to determine whether thrombocytopenia is caused by vancomycin-dependent antibodies in patients being treated with vancomycin. METHODS We identified and characterized vancomycin-dependent, platelet-r...

In this study, the antibiotic resistance (AR) of lactic acid bacteria (LAB) isolated from traditional Turkish fermented dairy products was investigated. Yogurt, white cheese, tulum cheese, cokelek, camız cream and kefir as dairy products were collected from various supermarkets. Lactic acid bacteria such as Lactobacillus spp., Streptococcus spp., Bifidobacterium spp., and Enterecoccus spp. were...

The levels of effectiveness of linezolid, vancomycin, and the combination of linezolid and vancomycin were compared in the rabbit model of endocarditis caused by a clinical methicillin-resistant Staphylococcus aureus (MRSA) isolate. Vancomycin alone was more effective than either linezolid alone or the combination of linezolid and vancomycin for the treatment of endocarditis due to MRSA.

The in vitro susceptibilty of Staphylococcus aureus to vancomycin was evaluated from impatients at a Brazilian University Hospital by the Etest and a screening method. No vancomycin intermediate (VISA) or vancomycin resistant (VRSA) S. aureus isolate was identified. Three patients presented as heteroresistant VISA (h-VISA) isolates but none of them received vancomycin previously.

Vancomycin resistance has been reported in clinical isolates of both coagulase-negative staphylococci and Staphylococcus aureus. The emerging threat of widespread vancomycin resistance poses a serious public health concern given the fact that vancomycin has long been the preferred treatment of antibiotic-resistant gram-positive organisms. Though major efforts are now being focused on improving ...

OBJECTIVES To report nephrotoxicity in the form of acute tubular necrosis (ATN) related to vancomycin. METHODS This study was conducted at Johns Hopkins Aramco Healthcare, Saudi Aramco, Dharan, Saudi Arabia between June and August 2013. All patients who received intravenous vancomycin as a part of the hospital's vancomycin stewardship program were monitored for the development of ATN. RESUL...

There have been conflicting data about the interactions between vancomycin and beta-lactam agents against Staphylococcus aureus strains with heterogeneous resistance to vancomycin. We evaluated the efficacy of these combinations against Mu 3 and heterogeneously vancomycin-resistant S. aureus (hetero-VRSA) strains which were isolated from Korean patients using a population analysis method. Antag...

Vancomycin resistance exhibited by Enterococcus faecalis isolates V583, V586, and V587 is described. The vancomycin MICs ranged from 32 to 64 micrograms/ml. Although resistant to vancomycin, the isolates were susceptible to teicoplanin (MIC, less than or equal to 0.5 micrograms/ml). Such a glycopeptide susceptibility profile has not been previously described for E. faecalis. Time kill studies s...

The drug hypersensitivity syndrome (DHS) is a severe, idiosyncratic multi-system reaction caused by drugs. It is defined by the clinical triad of fever, rash and internal organ involvement 1) . Vancomycin has rarely been reported as a cause of the DHS 2) . There are only a few cases of suspected DHS due to vancomycin previously reported in the medical literature 3-5) . In 1990, Hannah et al. 3)...
