RAISUS is a system for rapid bacterial identification and antimicrobial susceptibility testing. RAISUS and VITEK showed 97.8% and 75.9% agreement in identification of 45 Staphylococcus aureus strains and 58 coagulase-negative staphylococci (CoNS), respectively, and RAISUS and CLSI (formerly NCCLS) methods showed 87.2% and 87.9% agreement in the MICs for S. aureus and CoNS, respectively. RAISUS ...

The standard iron-chelator deferoxamine is known to prevent the growth of coagulase-negative staphylococci (CoNS) which are major pathogens in iron-overloaded patients. However, we found that deferoxamine rather promotes the growth of coagulase-positive Staphylococcus aureus. Accordingly, we tested whether deferiprone, a new clinically-available iron-chelator, can prevent the growth of S. aureu...

ISSN: 2319-7706 Volume 4 Number 5 (2015) pp. 172-190 http://www.ijcmas.com Neonatal sepsis is a leading cause of neonatal mortality in developing countries. Identification of the etiological agents of neonatal sepsis is essential for effective treatment. Out of 106 microbial isolates recovered from blood cultures of late onset neonatal sepsis (LONS) patients, only 70 (66 %) isolates were Gram-p...

A total of 288 staphylococcal specimens isolated from different clinical specimens were selected for the evaluation of tests used to detect Staphylococcus aureus. The coagulase (coa) gene PCR was preformed, which confirmed 288 specimens as S. aureus and 51 specimens as coagulase negative staphylococci (CONS). All the specimens were subjected to slide coagulase test, Slidex Staph plus test and t...

conclusions fortunately, due to its lower virulence as compared to its cousin s. aureus, pji due to cons may display higher remission rates than s. aureus-caused pji after combined surgical and medical management. results the main differences between the pathogens lie in the clinical presentation of pji, the presumed origin of infection, and the presence of a higher proportion of methicillin-re...

patients and methods: all samples sent to the lab were routinely processed according to standard microbiological procedures and the cultures yielding growth of cons were selected for the study. all samples containing cons collected over a 2 year-period, were included irrespective of patients' age and gender. the antibiogram of the organisms was recorded according to clsi guidelines and the rati...

results of total 60 s. aureus isolates, 51 (85%) were mrsa, and of 60 cons, 7 (11.66%) were mrcons. the results showed that the mic of chlorhexidine for all 120 isolates was 1-16 μg/ml. 15 (12.5%) isolates carried qaca/b gene, 26 (21.7%) carried qacc gene, and 38 (31.7%) carried smr gene. conclusions maintenance of mrsa isolates in the attendance of low amounts of antiseptics could result in th...

The genus Staphylococcus is composed of Gram-positive bacteria with diameters of 0.5-1.5 μm, characterized by individual cocci that divide in more than one plane to form grape-like clusters [1]. These bacteria are non-motile, nonspore forming facultative anaerobes, featuring a complex nutritional requirement for growth [2-4], a low G+C content of DNA (in the range of 30-40 mol%) [5], a toleranc...

Coagulase-negative staphylococci (CoNS) are often associated with bovine mastitis and may be resistant to antimicrobial therapy. The aim of the current study was to investigate the presence of blaZ (responsible for penicillin resistance) and mecA (responsible for methicillin resistance) genes among 108 CoNS belonging to 9 different species isolated from bovine mastitis in seven dairy herds (H1-...

18 Background 19 Nasal colonization with coagulase-negative Staphylococcus (CoNS) has been 20 described as a risk factor for subsequent systemic infection. In this study, we aimed to 21 evaluate the profile of CoNS isolates colonizing the nares of children admitted to a 22 neonatal intensive care unit (NICU) of a major city located in central Brazil. 23 Methods 24 We assessed CoNS carriage at a...
