Evaluating the Co-commensal Lifestyles of Staphylococcus aureus and Staphylococcus epidermidis
Staphylococcus epidermidis is a ubiquitous skin commensal, and produces a serine protease Esp that can eradicate nasal carriage of the opportunistic pathogen, Staphylococcus aureus. We evaluated the ability of S. epidermidis and S. aureus to express serine protease and compete with one another in …

Epidemiologische und molekulare Untersuchungen zur Biofilmbildung in Staphylococcus epidermidis und Staphylococcus aureus
Staphylococcus aureus und Staphylococcus epidermidis gehören zu den häufigsten Erregern nosokomialer Infektionen bei immunsupprimierten Patienten. Gleichzeitig bilden diese Bakterien einen wesentlichen Teil der gesunden Hautflora des Menschen. Bisher ist wenig darüber bekannt, ob es Unterschiede in …

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 …

Staphylococcus aureus and Staphylococcus pseudintermedius in animals: molecular epidemiology, antimicrobial resistance, virulence and zoonotic potential
Staphylococcus aureus es colonizador común de la piel y mucosas del hombre y otros animales y el perro es el hospedador habitual de S. pseudintermedius. Ambas especies son también importantes patógenos oportunistas. La epidemiología y ecología de estas especies bacterianas en animales ha cobrado …

Staphylococcus coagulase positiva e Staphylococcus aureus resistentes a antibióticos em cadeia produtiva de carne suína
… do consumidor. Em relação a carne suína, Staphylococcus coagulase positiva (SCP) possui grande importância por serem importantes indicadores das condições de manipulação, e também por indicarem a presença de S. aureus, que na cadeia produtiva de suínos possui relevância pela possibilidade …

Investigating the effect of Staphylococcus epidermidis on the growth dynamics of Staphylococcus aureus in atopic dermatitis
… inconsistencies in the interactions between Staphylococcus epidermidis and Staphylococcus aureus concerning growth and biofilm formation outcomes. This suggests that there might be a strain-level role played by the bacteria that affect the outcomes of their interactions, and consequently, the …

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
In vivo expression technology (IVET) is a promoter-trap strategy deigned to identify genes whose expression in induced in a specific environment, typically that encountered in a host. Signature-tagged mutagenesis (STM) uses comparative hybridisation to isolate mutants unable to survive specified …

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 …
