background : reports on the association of nosocomial bacterial infections with indwelling medical devices such as intravenous catheters (ivc) has increased in recent years. the potential to form biofilm on these devices seems to be the main reason for establishment of such infections. the aim of this study was to measure the potential of biofilm formation by bacterial isolates from ivcs. metho...

background and objectives: to investigate coagulase gene polymorphisms of mrsa and mssa isolates from shiraz teaching hospitals from 2011 to 2012. materials and methods: a total of 302 isolates of staphylococcus aureus were collected from clinical specimens in three major teaching hospitals and confirmed on the basis of morphological characteristics and biochemical tests. the isolates were subj...

conclusions our results showed that c. albicans was the most frequently isolated from both patients with vaginitis and normal individual. in the present study, we could not find any correlation between extracellular activities and sources of isolates (patients and normal flora) and sensitivity or resistance to fluconazole. background extracellular phospholipase, proteinase, and coagulase are ac...

OBJECTIVE Oral candidiasis, in the form of Candida-associated denture stomatitis, represents a common disease in a large percentage of denture wearers, and Candida albicans remains the most commonly isolated species. In this study, we aimed to evaluate biofilm production, coagulase and hemolytic activity of Candida species isolated from denture stomatitis patients. MATERIALS AND METHODS This ...

OBJECTIVE This study sought to evaluate infections related to health care caused by coagulase-negative Staphylococci in a neonatal intensive care unit by assessing antimicrobial susceptibility profiles and potentially effective antibiotic regimens. METHODS This was a retrospective descriptive study performed on a case series of healthcare-associated infections, and the antimicrobial susceptib...

Several observers have reported that plasmas differ in their susceptibility to staphylocoagulase. Chapman' tested 81 fresh human blood samples with a ten-hour staphylococcus culture, and noted that at two hours firm clots had formed with 35, partial clots with 25, while 21 bloods remained unclotted. The suggestion that such variation in human plasmas may be due to the activity of "inhibitors" h...

The following organisms have shown in vitro sensitivity to DBLTM Cefotaxime Sodium for Injection. Gram-positive: Staphylococci spp, including coagulase-positive, coagulase-negative and penicillinase-producing strains. Streptococci spp, including β-haemolytic and other streptococci such as Streptococcus mitis (viridans), Streptococcus pneumoniae. (Many strains of enterococci, e.g. Streptoco...

The susceptibilities of 107 urinary isolates of coagulase-negative staphylococci to 19 antibiotics was determined by an agar dilution technique. Major differences in the antimicrobial susceptibilities of species of coagulase-negative staphylococci were observed. Staphylococcus epidermidis was more resistant to a wider spectrum of antibiotics than was Staphylococcus saprophyticus.

BACKGROUND Genome-wide gene expression profiling allows for identification of genes involved in the defense response of the host against pathogens. As presented here, transcriptomic analysis and bioinformatics tools were applied in order to identify genes expressed in the mammary gland parenchyma of cows naturally infected with coagulase-positive and coagulase-negative Staphylococci.
