Seventeen strains of ten different species of coagulase-negative staphylococci were shown to interact with collagen, laminin, fibronectin, and vitronectin immobilized on latex beads. Different species of coagulase-negative staphylococci have different capacities to agglutinate proteins. Cells of 18 strains of Staphylococcus haemolyticus reacted more strongly than did cells of 18 Staphylococcus ...

INTRODUCTION Staphylococcus lugdunensis is an unusually virulent coagulase-negative staphylococcus that has rarely been implicated in central nervous system infections. CASE PRESENTATION Two children hospitalized in the Neurosurgery Unit developed ventriculitis caused by methicillin-resistant Staphylococcus lugdunensis following placement of external ventriculostomy drains. The causative orga...

Greywater reuse is a feasible solution for decreasing raw water extraction in urban and rural settings. However, pathogen-specific performance guidelines and regulations have only recently been recommended; practical means to assess performance are missing. Here we examine the efficacy of Staphylococcus spp. as an endogenous surrogate for greywater pathogen reduction performance testing, by eva...

Staphylococcus hyicus demonstrated characteristic bacteriolytic activities towards a Micrococcus luteus reference strain. This lytic activity was demonstrated on medium containing M. luteus cells as large zones of transparency around the culture streak. Smaller zones of transparency were observed with Staphylococcus intermedius, Staphylococcus chromogenes, and some strains of Staphylococcus aur...

Phenolphthalein diphosphate was incorporated into a primary blood agar medium for use in performing quantitative urine cultures. Phosphatase-negative staphylococci, such as Staphylococcus saprophyticus, were differentiated from phosphatase-positive species, such as Staphylococcus epidermidis, by spot testing colonies on filter paper saturated with 1 N NaOH. Phosphatase-positive colonies turned ...

BACKGROUND This study compared the pharmacodynamics of ceftobiprole and vancomycin against methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-intermediate S. aureus (VISA) and vancomycin-resistant S. aureus (VRSA) using an in vitro model. METHODS Two methicillin-susceptible S. aureus (MSSA), two community-associated (CA)-MRSA, one healthcare-associated (HA)-MRSA, three VISA and tw...

Background CoNS species are likely reservoirs of the staphylococcal cassette chromosome mec (SCC mec ) in Staphylococcus aureus . S . aureus CC395 is unique as it is capable of exchanging DNA with CoNS via bacteriophages, which are also known to mediate transfer of SCC mec . Objectives To analyse the structure and putative origin of the SCC mec element in S . aureus CC395. Methods The only ...

conclusions these findings showed no significant difference regarding the presence of icaadbc genes between blood and wound isolates. background the polysaccharide intercellular adhesion (pia) produced by staphylococcus aureus is effective in the protection of isolates from outer harsh conditions and progress of infection. objectives the aim of this study was to compare the icaabcd genes encodi...

the use of quantitative structure–activity relationships, since its advent, has becomeincreasingly helpful in understanding many aspects of biochemical interactions in drug research.this approach was utilized to explain the relationship of structure with biological activity ofantibacterial. for the development of new fungicides against, the quantitative structural–activityrelationship (qsar) an...

the present study was aimed to identify the frequency of coagulase (coa) and thermonuclease (nuc) genes and staphylococcal enterotoxin a (sea) production among staphylococcus aureus isolated from various sources in shiraz. moreover, the correlation between the sea gene and coagulase and thermonuclease enzymes is also considered. a total of 100 s. aureus were isolated from various sources includ...
