GENOMIC DIVERSITY IN Staphylococcus Aureus
<p><em>Staphylococcus aureus</em> chromosomal DNA from 125 methicillin-resistant and 10 methicillin-sensitive clinical isolates was digested with rare-cutting restriction endonucleases and subjected to pulsed-field gel electrophoresis (PFGE). Thirty-nine distinct genomic macrorestriction patterns …

Characterisation of lipoproteins in staphylococcus aureus
The Gram-positive bacterium Staphylococcus aureus is an extremely successful opportunistic bacterium capable of causing a wide range of hospital-acquired and community-acquired infections, and is becoming increasingly virulent and resistant to antibiotics. In order to investigate this pathogen, …

Characterization of Vancomycin Resistance in Staphylococcus Aureus
In the past decade, Staphylococcus aureus has developed two distinct vancomycin resistance mechanisms. First, the bacterium is capable of generating a thickened, poorly crosslinked cell wall that creates false targets. These targets cause vancomycin to bind at the periphery of the thickened …

Applications of Sortase A from Staphylococcus aureus
Sortase A (SrtA) mediated ligation provides a mild and site-specific method for attaching a wide range of molecular probes to biological molecules, such as proteins and DNA. This method does not require any toxic reagents or harsh conditions to achieve high level of labelling, and the product could …

Incidence of Staphylococcus Aureus on Fomentation Covers
… fomentation covers were contaminated with <em>Staphylococcus aureus</em> prior to being placed on a patient receiving a hydrotherapy treatment.</p> <p>From a review of literature on the subject of the <em>Staphylococcus aureus</em> organism and from studies of hospital-acquired staphylococcal …

Study of virulence factors of Staphylococcus aureus
… have been used to identify virulence genes in S. aureus. The main aim of this project was to find any probable new genes of S. aureus that are essential for biofilm formation and infection mouse model by STM. A library of tagged insertion mutants of S. aureus and a series of selected tags in …

Catalase, Superoxide Dismutase, and Staphylococcus Aureus Virulence
Staphylococcus aureus is known to possess a wide variety of parameters that enable it to defend itself against host defense mechanisms. One of the ways the body defends itself against microbial attack is by producing superoxide radicals and hydrogen peroxide. These oxygen-free radicals are known to …

Characterization of Staphylococcus Aureus of Bovine Origin
The incidence of mastitis caused by Staphylococcus aureus was of the same order as that reported by other investigators. However, the strains isolated were not all of the bovine biotype. The strains isolated from the mammary gland and nasal cavity, although mostly of bovine biotype, differed in …

Integrin-vermittelte Invasion von Staphylococcus aureus in Säugerzellen
Der Gram-positive Erreger Staphylococcus aureus ist ein Bestandteil der normalen Haut und Schleimhautflora des Menschen, kann aber auch ein weites Spektrum von Krankheitsbildern hervorrufen. Ein besonderes Charakteristikum dieses Pathogens besteht in der Expression von Oberflächenstrukturen, welche …

Targeting Receptor-Histidine Kinase Signaling in Staphylococcus Aureus
… agr signaling circuit in the bacterial pathogen, Staphylococcus aureus, is one system where the ligands are known in chemical detail. These ligands (the AIPs) are short (7-9 aminoacyl residue) peptides containing a thiolactone structure, in which the α-carboxyl group of the C-terminal amino acid …

Staphylococcus aureus DNA gyrase: mechanism and drug targeting
Increases in Staphylococcus aureus resistance against existing treatment options and the shortage of new antibiotics signals an urgent need for new treatments for the ongoing battle against the development of antibiotic resistance. DNA gyrase is an essential bacterial type II DNA topoisomerase that …

Genomic investigation into the evolution of <i>Staphylococcus aureus</i> and the micro-epidemiology of <i>Staphylococcus aureus </i>in atopic eczema
Staphylococcus aureus is a highly adaptable organism, which has established itself as one the most important pathogens worldwide. It has co-evolved with humans adapting to life within the host as well as the interventions targeted to eradicate it. Despite its notoriety as a pathogen one of its …

The Biological Burden of Antibiotic Resistance in Staphylococcus aureus
… cell growth by comparing the growth rates of <em>Staphylococcus aureus</em> with and without 10 plasmids. Plasmid-ffee cells were mixed with equal numbers of plasmid-containing cells and propagated serially through 10 cultures for 5 days without antibiotics. The ratio of sensitive to resistant …

Compartmental responses of the respiratory tract to Staphylococcus aureus
Methicillin-resistant Staphylococcus aureus (MRSA) is an important nosocomial pathogen associated with significant morbidity and mortality. Previous colonisation with this pathogen is a risk factor for the development of subsequent infection. Tolllike receptors (TLRs) are a family of transmembrane …

Effect of iron and haemoglobin on Staphylococcus aureus biofilms
The biofilm infection of Staphylococcus aureus is one of its most common and ‘silently’ harmful virulence traits, leading to endocarditis, central line-associated bloodstream infections, ventilator associated pneumonia, implant-related infection and surgical site infections among others. Biofilms …
