OBJECTIVES To determine the rates of mupirocin resistance in staphylococci during a 4 year period (1999-2002) in Greece. MATERIALS A total of 1200 Staphylococcus aureus and 2760 coagulase-negative staphylococci (CoNS), consecutively collected from four Greek hospitals located in different geographical areas, were tested for susceptibility to mupirocin using the Etest and a reference agar dilu...
Staphylococcus spp. is a major cause of nosocomial infection and sepsis. However, increasing drug resistance is becoming a challenge to microbiologists. The purpose of this study was to identify and determine antimicrobial resistance phenotypes and drug resistance genes of clinical coagulase-negative staphylococci (CoNS) isolates at Mae Sot Hospital in Tak province, Thailand. A total of 229 CoN...
22 A novel rapid PNA FISH method, Staphylococcus QuickFISH, for the direct 23 detection of Staphylococcus species from positive blood culture bottles was 24 evaluated in a multicenter clinical study. The method utilizes a microscope slide 25 with pre-deposited positive and negative control organisms and a self-reporting 26 15 minute hybridization step which eliminates the need for a wash step. ...
Background: Staphylococci as a micro-organism, has the most importance to cause nosocomial infections, particularly in patients with indwelling catheters or other medical devices. Unfortunately 90% of Staphylococci isolated from the nosocomial infections are resistant to methicillin, and methicillin resistance strains are also resistant to a wide range of antimicrobial drugs, therefore detectin...
results fifty-three (53%) isolates were simultaneously resistant to erythromycin, azithromycin and clarithromycin (cross-resistance); while 8 (8%) isolates had variable macrolide susceptibility pattern. among the s. aureus isolates, the difference in prevalence of resistance to erythromycin between males and females was significant (p = 0.011). the frequency of erma, ermb, ermc, and msra genes ...
Given the inappropriate use of antibiotics and prevalence of resistant bacteria, there is urgentneed for antibacterial drugs that have fewer side effects than antibiotics. Satureja bachtiaricais a medicinal plant which had many uses in traditional medicine. In this research, the ethanolextract of leave of Satureja bachtiarica is tested on coagulase-negative staphylococcus strains.Materials and ...
Coagulase-negative staphylococci (CoNS) are important nosocomial pathogens and the leading cause of sepsis. The second most frequently implicated species, after Staphylococcus epidermidis, is Staphylococcus haemolyticus. However, we have a significant lack of knowledge about what causes virulence of S. haemolyticus, as virulence factors of this pathogen have remained virtually unexplored. In co...
Background and Objective: Reliable methods of detection of antimicrobial resistance are of paramount importance in the treatment and management of infections caused by coagulase negative staphylococci (CoNS). The objective of the present study was to compare and evaluate the performance of disc diffusion and E test (Epsilometer test) methods for antimicrobial testing of coagulase ne...
BACKGROUND This study aimed to summarize common pathogens and associated drug resistance in neonatal sepsis (NS). METHODS Blood culture and drug sensitivity results from 96 NS cases treated from January 2010 to August 2014 were retrospectively analyzed. RESULTS A total of 97 pathogenic bacteria were detected from these 96 NS cases; Gram-positive cocci accounted for 76.3% of the cases, among...
Although opportunistic pathogens, coagulase-negative staphylococci (CoNS), including Staphylococcus epidermidis and Staphylococcus haemolyticus, have long been regarded as avirulent organisms. The role of toxins in the development of infections caused by CoNS is still controversial. The objective of this study was to characterize the presence of enterotoxin and cytotoxin genes in S. epidermidis...
