Molecular Characterization of Methicillin-Resistant Staphylococcus aureus Isolates, Isolated from a Burn Hospital in Southwest Iran in 2006 and 2014.
Conclusion: The predominance of ST-239 in this region during the last eight years is a major concern. It also has a disturbing impact on the management of staphylococcal infections. Moreover, the SCCmec type IV strain is able to disseminate rapidly in hospital environments, demanding an improvement in infection-control policy. PMID: 29887890 [PubMed]
jun Yang Wenyu Han Jingmin Gu Staphylococcus aureus (S. aureus) is a common and dangerous pathogen that causes various infectious diseases. Skin damage, such as burn wounds, are at high risk of Staphylococcus aureus colonization and infection, which increases morbidity and mortality. The phage lysin LysGH15 exhibits highly efficient lytic activity against methicillin-resistant S. aureus (MRSA) and methicillin-susceptible S. aureus (MSSA) strains. Apigenin (api) significantly decreases haemolysis of rabbit erythrocytes caused by S. aureus and shows anti-inflammatory function. LysGH15 and api were added to Aquaphor t...
Conclusions Patient privacy curtains became progressively contaminated with bacteria, including MRSA. Between days 10 and 14 after being hung, curtains showed increased MRSA positivity. This may represent an opportune time to intervene, either by cleaning or replacing the curtains.
Conclusions The results of this study indicate that the prevalence of MRSA among burn patients is very high in Iran. Thus, a comprehensive infection control strategy based on hand hygiene, education and training in antibiotic prescribing, environmental cleaning, contact precautions, good antibiotic stewardship and an active surveillance system on the basis of international criteria is urgently needed.
In this study, the anti-infection activity of AgNP immobilized biomaterials was evaluated, facilitated by argon plasma grafting technology and activated by bacterial colonization. The modified materials generated in this study showed excellent specificity and were active against both Gram-positive and Gram-negative biofilm forming bacteria, including methicillin-resistant Staphylococcus aureus, Staphylococcus epidermidis, and Escherichia coli. The anti-infection biomaterials developed in this study demonstrate several attractive advantages in comparison to traditional anti-bacterial surfaces loaded with antibiotics or othe...
Conclusion A comprehensive concept is required to control the spread of all multidrug-resistant micro-organisms including MRSA on a burn unit. Where patients colonized or infected with MRSA appear to be the main reservoir, transfer of these patients to other units, or temporary closure of the unit, accompanied by intensive cleaning are very effective measures to stop transmission events.
In conclusion, our study suggests that MRSA infection is serious in our burn center, but presented decreased trend over time. Most of MRSA isolates in our center presented the same virulence factor profile. More attention should be attached to nosocomial infection in burn medical center. Antimicrobials susceptibility changing over time was observed. Antimicrobials susceptibility monitoring is necessary and helps to select appropriate drugs against MRSA infections.
Conclusion A comprehensive concept is required to control the spread of all multi-drug resistant microorganisms including MRSA on a burn unit. Where patients colonized or infected with MRSA appear to be the main reservoir transfer of these patients to other units, or temporary closure of the unit, accompanied by intensive cleaning are very effective measures to stop transmission events.
This study first demonstrates a potential role of MVs in the biofilm formation by S. aureus, stresses on the importance of avoiding low dose of antibiotic therapy in controlling of S. aureus infections, and provides further information to reveal the mechanisms behind MRSA infections.
Conclusions/implications While bismuth subsalicylate, and bismuth tribromophenate unbound to Xeroform® demonstrate antimicrobial activity, it appears that Xeroform® dressings do not. The utility of Xeroform® in burn medicine may relate more to use as an impervious dressing than to antimicrobial effect. Donor sites are clean surgical wounds and clean partial thickness burns may have minimal colonization present. In such circumstances, an inactive and impervious dressing may be all that is necessary to promote wound healing. Graphical abstract
Discussion and conclusion Emerging bacterial drug resistance has both clinical and financial implications for the therapy of infected burn patients. Spectrum of bacterial drug resistance in an institution is important for epidemiological as well as clinical purposes. Rising frequency of MDR strains in burn patients is alarming for clinicians as it downgrades the treatment efficacy.
