This study aims to investigate the prevalence of a novel cell wall-anchored protein gene, sasX, and to obtain information on the genetic basis for the pathogenic potential of the MRSA strains isolated from Chinese children. The molecular and virulence characteristics of the clinical strains were analyzed. Twenty-two sequence types (STs) were obtained, with(More)
AIM To investigate and compare the characteristics of invasive hospital-associated (HA) and community-associated (CA) methicillin-resistant Staphylococcus aureus (MRSA) infections in Chinese children. METHODS Clinical data on 59 paediatric patients with invasive MRSA isolated from the normally sterile sites between 2006 and 2011 were obtained from the(More)
BACKGROUND This study aims to investigate the clinical features of invasive community-acquired Staphylococcus aureus (CA-SA) infection in Chinese children and analyze its molecular features. METHODS Clinical data and invasive CA-SA isolates were prospectively collected. Pediatric risk of mortality (PRISM) score was used for disease severity measurement.(More)
BACKGROUND Reports suggest that the prevalence of community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) has increased, and that CA-MRSA is more virulent than healthcare-associated (HA)-MRSA. AIMS The aim of this study is to gain a better understanding of the invasiveness and prevalence of CA-MRSA in patients; we systematically reviewed(More)
This study aims to characterize the clinical features of community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) infections in Chinese neonates, as well as the molecular characteristics and expression of key virulence genes of isolates. Clinical information and molecular characteristics of 130 cases were analyzed. Up to 83.8% patients were(More)
Quantitative evaluation of scientists now has become very important at many aspects in the range of nation, even all over the world. Among the indices used for quantitative evaluation, h-type indicators are the most popular right now. However, because of the problem that mastering more than 40 variants is difficult and time-consuming, we need an intuitional(More)
Two novel and neutral benzimidazole derivatives-based anion receptors bearing a 1,10-phenanthroline fluorophore, N,N′-di-(2′-benzimidazolyl-methylene)-1, 10-phenanthroline-2,9-diamide (1) and N,N′-di-[2′-(benzimidazolyl-2′-) ethyl-]-1,10-phenanthroline-2,9-diamide (2), which exhibited turn-on and turn-off fluorescence responses to various anions, were(More)
Tris-hydrazone (1) functioned as a colorimetric chemosensor for a variety of anions such as F(-), AcO(-) and H(2)PO(4)(-). The anion binding could be easily detected by naked-eye according to color changes. The high binding ability of the receptor 1 to anions was further investigated by UV-vis absorption spectroscopy in DMSO. The results of job plot of the(More)
BACKGROUND This study was conducted to investigate the clinical features of hospital-associated infections (HAIs) caused by methicillin-resistant Staphylococcus aureus (MRSA) in Chinese children, and the molecular characteristics of the bacteria. METHODS Patients with HAIs caused by MRSA were identified retrospectively. All isolates were analyzed using(More)
