Panton-Valentine Positive Staphylococcus aureus in Community-Acquired and Hospital-Acquired Pediatric Infections

From July 2009 to July 2015, Staphylococcus aureus isolated from pediatric sterile sites were selected. Polymerase chain reaction was used to detect mecA and lukS-PV/lukF-PV genes. The rate of methicillin-resistant Staphylococcus aureus was 37.7%. Ten isolates had the lukS-PV/lukF-PV genes, 2 of which were methicillin-resistant Staphylococcus aureus. Skin and soft tissues infections were significantly associated with lukS-PV/lukF-PV positive isolates, P = 0.008.

Health care –associated infections (HCAIs) are a significant concern for both health care workers (HCWs) and patients. They are a major contributing factor of disease in industrialized countries, and are responsible for significant morbidity, mortality, and a direct annual financial loss of $6-7 billion in No rth America alone. They are an increasingly challenging health issue due to multidrug-resistant pathogens such as methicillin-resistant Staphylococcus aureus and vancomycin-resistant Enterococci among others, along with an increasing number of susceptible patients.

The crude extracts showed strong antimicrobial activity against human pathogens. Biologically active compounds were isolated and purified by chromatographic methods. The structures of the pure compounds were elucidated by spectroscopic methods. They were identified as Violaceol I and Violaceol II. These compounds...

Publication date: Available online 12 October 2019Source: Journal of Advanced ResearchAuthor(s): Yanguang Cong, Sijin Yang, Xiancai RaoAbstractThe infection caused by methicillin-resistant Staphylococcus aureus (MRSA) is a global threat to public health. Vancomycin remains one of the first-line drugs for the treatment of MRSA infections. However, S. aureus isolates with complete resistance to vancomycin have emerged in recent years. Vancomycin-resistant S. aureus (VRSA) is mediated by a vanA gene cluster, which is transferred from vancomycin-resistant enterococcus. Since the first VRSA isolate was recovered from Michigan, ...

Staphylococcus aureus, particularly methicillin-resistant S. aureus (MRSA), is an important human pathogen that exhibit enhanced virulence and resistance to different antibiotics. It causes a wide range of infections from mild to life-threatening conditions, both in the hospital (healthcare-associated-infections/HAIs) and in the community (community-associated-infections/CAIs), resulting in increased costs for the healthcare system [1,2]. Although there has been a recent decrease in HAIs (but not among CA invasive infections), caused by MRSA, in EEUU [3] and in some European countries [4], the attributable mortality due to...

Authors: Bassetti M, Russo A, Carnelutti A, Wilcox M Abstract Introduction: In clinical practice, methicillin-resistant Staphylococcus aureus (MRSA) represents a major threat and has been associated with high rates of inadequate antibiotic treatment and significant increases in morbidity, mortality and overall healthcare costs. The association between the prescription of an inappropriate or delayed antibiotic and impaired clinical outcomes has been widely described. Areas covered: To address the threat of MRSA, many new therapeutic options with a peculiar activity against MRSA have been recently developed and appro...

Planta Med DOI: 10.1055/a-1013-0434The development of multiple antibiotic–resistant bacteria has vastly depleted our repertoire of effective antibiotic chemotherapies. The development of multi-β-lactam-resistant strains are particularly concerning due to our previous reliance on this class of antibiotics because of their initial efficacy and broad-spectrum activity. With increases in extended-spectrum β-lactam-resistance and an expanded resistance to other classes of antibiotics, there is an urgent need for the development of effective new antibiotic therapies. Terminalia ferdinandiana is an endemic Austral...

CONCLUSION: Catheter removal and anticoagulation are modestly effective. Surgery is associated with poor outcomes. Despite contemporary management, infective haemodialysis CRAT still results in high mortality. Prospective studies are needed to identify the optimal management.
