The isoleucyl-tRNA synthetase (ileS) gene was sequenced in toto from 9 and in part from 31 Staphylococcus aureus strains with various degrees of susceptibility to mupirocin. All strains for which the mupirocin MIC was greater than 8 microg/ml contained point mutations affecting the Rossman fold via Val-to-Phe changes at either residue 588 (V588F) or residue 631 (V631F). The importance of the V5...

BACKGROUND Staphylococcus epidermidis is a part of the skin's normal flora that can cause acne. This study was designed to evaluate the efficacy of nicotinamide as a stick in eradication of staphylococcus. MATERIALS AND METHODS For evaluating of Anti-microbial effect on S. epidermidis used well plate method. We chose five plates for nicotinamide and five for mupirocin. The zones of inhibition...

Recent data show that more than 50% of catheter-associated bloodstream infections are caused by staphylococci. Staphylococcal infections produced by intercellular-adhesion cluster (ica) carriers can be even more problematic due to the presence of methicillin and mupirocin resistance genes. In the present study, a multiplex PCR protocol that allows the simultaneous identification of staphylococc...

In a retrospective study, Dr Muller and colleagues have assessed the efficacy of mupirocin nasal ointment alongside hygienic measures in methicillin-resistant Staphylococcus aureus (MRSA)-positive patients admitted to the intensive care unit (ICU). Their findings, which suggest that intranasal mupirocin can prevent ICU-related MRSA infections, need confirmation in a well-designed clinical trial...

TPY agar supplemented with mupirocin (100 mg/liter) and glacial acetic acid (1 ml/liter) was effective in the enumeration of bifidobacteria in animal (11 species) fecal or intestinal samples. On the other hand, less than 50% of isolates from pig feces were identified as Bifidobacterium sp. using this medium. Subsequently TPY agar modified by the addition of mupirocin (100 mg/liter), glacial ace...

Objective: This study was done to evaluate the susceptibility of Staphylococcus aureus mupirocin and determine antimicrobial pattern among various clinical isolates. Methods: All consecutive, non-duplicative isolates collected during year 2020 were subjected disk diffusion method stocked. Mupirocin for all stocked detected by Minimal inhibitory concentration (MIC) determination Epsilometer test...

BACKGROUND Eradication of methicillin-resistant Staphylococcus aureus (MRSA) carriage may reduce the risk of MRSA infection and prevent transmission of the organism to other patients. METHODS To determine the efficacy of decolonization therapy, patients colonized with MRSA were randomized (3:1 allocation) to receive treatment (2% chlorhexidine gluconate washes and 2% mupirocin ointment intran...

Staphylococcus aureus has been consistently isolated from a high proportion of impetiginous lesions, and in several recent studies, it was present in the majority of the cases. Since recently a large proportion of S. aureus strains in our community showed erythromycin resistance, we undertook a prospective double-blind controlled study comparing topical mupirocin with oral erythromycin to deter...

Objectives To investigate the efficacy of a potent novel antimicrobial protein of mass 6 kDa, epidermicin NI01, for eradicating the nasal burden of MRSA in a cotton rat ( Sigmodon hispidus ) model. Methods MRSA strain ATCC 43300 was used to establish a robust colonization of cotton rat nares. This model was used to evaluate the efficacy of topical 0.04% and 0.2% epidermicin NI01, administered...

background : infections resulted from multi-resistant staphylococcus aureus are increasing worldwide. in the present study, a multiplex-pcr assay for the detection of antibiotic resistance genes among s. aureus clinical isolates and for the concomitant identification of these isolates was described. methods : a total of 127 s. aureus isolates were collected from clinical specimens at three teac...
