background and objectives: presence of methicillin and multidrug resistance has associated coagulase negative staphylococci (cns) with high morbidity and mortality worldwide. the present study was carried out to study the susceptibility pattern of cns to various antimicrobial agents and to determine the prevalence of cns methicillin resistance in our hospital setting. materials and methods: a t...
conclusions regarding clinical and laboratory standards institute (clsi) definition for vancomycin susceptibility (mic < 2 μg/ml), it seems that vancomycin may not be considered as the best antibiotic in order to treat heteroresistant vancomycin intermediate s. aureus (hvisa) and vancomycin sensitive s. aureus (vssa) infections, and a new breakpoint for vancomycin and alternative antibiotics sh...
High-dose daptomycin (DAP) therapy failed in a neutropenic patient with bloodstream infection caused by a DAP-susceptible Enterococcus faecium (minimum inhibitory concentration, 3 µg/mL) harboring genetic changes associated with DAP resistance, with persistent bacteremia and selection of additional resistances. Daptomycin monotherapy should be used cautiously against DAP-susceptible E. faecium ...
EVALUATION OF ANTIOXIDANT AND ANTIFUNGAL PROPERTIES OF NEW DERIVATIVES OF PERAZOLO [3,4-D]PYRIMIDINE
Background & Aims: Heterocyclic compounds are found be abundant in nature, these compounds have many biological properties, and many drugs also contain heterocyclic rings. In this study, antioxidant and anti-fungal properties of the seven pyrazolo[3,4-d]pyrimidine compounds has been studied that synthesized in Iran and their good antibacterial properties have been reported Materials & Methods:...
Objectives:Biofilms are communities of bacteria attached to surfaces through an external polymeric substances matrix. In the meantime, Acinetobacterbaumannii is the predominant species related to nosocomial infections. In the present study, the effect of silver nanoparticles alone and in combination with biocides and imipenem against planktonic and biofilms of A. baumannii was assessed. Materi...
Background & Aims: Pseudomonas aeruginosa is a gram-negative bacterium which is capable of producing biofilm, phosphomycin is one of the broad-spectrum antibiotics and Zataria multiflora is among the most widely used medicinal plants. The aim of this study was to evaluate the combined effects of Phosphomycin and Z.multiflora essential oil against biofilm formation by P. aeruginosa PAO1...
A significant percentage survival, representing a large number of viable cells, can occur in a Staphylococcus aureus population exposed to concentrations of mupirocin up to 1,000 times the minimum inhibitory concentration. An elevated ratio of minimum inhibitory to minimum bactericidal concentration of mupirocin with staphylococci was recorded. Staphylococci which survive exposure to mupirocin ...
