Hospital-acquired infection with methicillin-resistant and methicillin-sensitive staphylococci [PDF]

Epidemiology and Infection, 1988
SUMMARYIn-patients at a London hospital over one year from whom the south-east England strain of ‘epidemic’ methicillin-resistant Staphylococcus aureus (MRSA) was isolated were compared with in-patients with strains of methicillin-sensitive Staphylococcus aureus (MSSA).

Light‐Switched Mesenchymal Stem Cells for In Situ Exosome Amplification in Craniofacial Bone Defect Reconstruction

Advanced Science, EarlyView.
Light‐switchable MSCs (MSC‐UCNPs) were constructed by intracellular incorporation of UCNPs. Upon 980 nm irradiation, UCNPs emitted localized ultraviolet light (365 nm), activating the ROS/HEXB/LAMP1 signaling pathway to suppress lysosome–multivesicular body fusion and thereby enhance exosome biogenesis. Embedded within an injectable hydrogel, MSC‐UCNPs

Caracterização fenotípica da resistência a antimicrobianos e detecção do gene mecA em Staphylococcus spp. coagulase-negativos isolados de amostras animais e humanas Phenotypic characterization of antimicrobial resistance and detection of the mecA gene in coagulase-negative Staphylococcus spp. isolates from animal and human samples

Ciência Rural, 2008
Os estafilococos coagulase-negativos (ECN) fazem parte da microbiota normal da pele e, apesar de terem sido considerados saprófitas por muito tempo, o seu significado clínico como agente etiológico tem aumentado com o passar dos anos. Neste estudo, foram

Methicillin and vancomycin resistance in coagulase-negative Staphylococci isolated from the nostrils of hospitalized patients

Journal of Infection in Developing Countries, 2020
Introduction: Nasal colonization by coagulase-negative Staphylococci (CoNS) play an important role in nosocomial infections. This study aims to determine antibiotics susceptibility pattern and molecular screening of methicillin- and vancomycin-resistant

Methicillin Potentiates the Effect of Gentamicin on Methicillin-Resistant Staphylococcus aureus [PDF]

Antimicrobial Agents and Chemotherapy, 1979
Methicillin-resistant Staphylococcus aureus (MRSA) strains show an unusual type of resistance at 37°C; only a small subpopulation of cells is resistant to the β-lactam antibiotics. Incubation in the presence of methicillin (MET), however, results in the emergence of a homogenous population highly resistant to MET ...

Pathogen‐Centric Activation of an Azoreductase‐Responsive Antibody‐Antibiotic Conjugate for the Targeted Eradication of MRSA

Advanced Science, EarlyView.
A pathogen‐centric antibody‐antibiotic conjugate (AZO‐AAC) releases antibiotics via bacterial azoreductase, independent of host‐lysosomal function. This mechanism achieves nanomolar eradication of both planktonic and intracellular methicillin‐resistant Staphylococcus aureus (MRSA).

The Effect of Methicillin on Skin Lesions in Guinea-Pigs Caused By "Methicillin-Sensitive" and "Methicillin-Resistant" Staphylococcus Aureus [PDF]

Journal of Medical Microbiology, 1974
SUMMARY The therapeutic effect of methicillin on skin lesions in guinea-pigs produced by two strains of Staphylococcus aureus showing heterogeneous resistance to methicillin, and by two strains of normal sensitivity, was compared. Methicillin was given intravenously immediately after the intradermal inoculation of staphylococci and the skin lesions ...

Microblasting Wound Dressings Mechanically Disrupt Polymicrobial Biofilms to Enhance Healing in Treatment‐Resistant Wounds

Advanced Science, EarlyView.
Treatment‐resistant wounds caused by polymicrobial biofilms are refractory to conventional therapies due to the dense extracellular matrices. We developed μBLAST, a microblasting wound dressing that combines MnO2‐doped biosilica and a H2O2‐releasing mesh to generate localized oxygen microbubbles that mechanically disrupt biofilms.

Characteristics of coagulase positive staphylococci isolated from milk in cases of subclinical mastitis

Acta Veterinaria, 2014
Coagulase-positive staphylococci are the most common pathogen causing subclinical mastitis in cows. Their main characteristic is a high virulence which leads to chronic infection.
