Von Willebrand factor-binding protein (vWbp), secreted by (), can activate host prothrombin, convert fibrinogen to fibrin clots, induce blood clotting, and contribute to pathophysiology of -related diseases, including infective endocarditis, staphylococcal sepsis and pneumonia. Therefore, vWbp is an promising drug target in the treatment of related infections. Here, we report that dryocrassin ABBA (ABBA), a natural compound derived from , can significantly inhibit the coagulase activity of vWbp by directly interacting with vWbp without killing the bacteria or inhibiting the expression of the vWbp.

Daptomycin is a treatment of last resort for serious infections caused by drug-resistant Gram-positive pathogens such as methicillin-resistant We have shown recently that can evade daptomycin by releasing phospholipid decoys that sequester and inactivate the antibiotic, leading to treatment failure. Since phospholipid release occurs via an active process, we hypothesised that it could be inhibited, thereby increasing daptomycin efficacy. To identify opportunities for therapeutic interventions that block phospholipid release, we first determined how the host environment influenced the release of phospholipids and inactivation of daptomycin by The addition of certain host-associated fatty acids to the growth medium enhanced phospholipid release.

Biofilm formation in the clinical environment is of increasing concern since a significant part of human infections is associated, and caused by biofilm establishment of (opportunistic) pathogens, for instance Candida albicans and Staphylococcus epidermidis. The rapidly increasing number of antibiotic-resistant biofilms urgently requires the development of novel and effective strategies to prevent biofilm formation ideally targeting a wide range of infectious microorganisms. Both, synthesis of extracellular polymeric substances and quorum sensing are crucial for biofilm formation, and thus potential attractive targets to combat undesirable biofilms. Read More

Background: A toxin-antitoxin (TA) system is a set of two or more closely linked genes that are encoded as a poison and a corresponding antidote on a protein. In typical bacterial physiology, an antitoxin binds to a toxin and neutralizes it, which prevents the bacterium from killing itself. We aimed to determine whether and isolates have TA genes and to investigate whether there is a relationship between the expression levels of TA genes and resistance to antibiotics. Read More

Emerging antimicrobial resistance has complicated treatment of systemic infections caused by CoNS. Here, we describe the prevalence of antimicrobial resistance in clinical CoNS strains from a tertiary care hospital over a four-year period, and observed a significant increase in resistance to daptomycin.

is a primary cause of biofilm-mediated infections in humans due to adherence to foreign bodies. A major staphylococcal biofilm accumulation molecule is polysaccharide intracellular adhesin (PIA), which is synthesized by enzymes encoded by the operon. Expression of PIA is highly variable amongst clinical isolates suggesting that PIA expression levels are selected in certain niches of the host. Read More

The purpose of this systematic review is to improve outcomes for the care of surgical site infections by presenting the current best evidence on important diagnostic and care issues. The findings led to ten recommendations and five consensus statements that address diagnosis and treatment of orthopaedic surgical site infections. There is strong evidence to supports anemia, obesity, HIV/AIDS, depression, dementia, immunosuppressive medications, duration of hospital stay, history of alcohol abuse, and history of congestive heart failure as factors that increased the risk of infection, some of which are modifiable before surgical intervention.

A pivotal event in the evolutionary path of methicillin-resistant (MRSA) is the acquisition of the staphylococcal cassette chromosome (SCC) element carrying the gene, the determinant of methicillin resistance. Community-acquired (CA) MRSA is commonly associated with skin/soft tissue infections, and doxycycline is one of the drug choices for this purpose. Doxycycline resistance is associated with the acquisition of the gene carried by the plasmid pT181, which may also be integrated into SCC III and V. Read More

Staphylococci are the main pathogens associated with hard-to-control intramammary infections in dairy cattle, and bacterial biofilms are suspected to be responsible for the antimicrobial resistance and persistence of this disease. Biofilms have the ability to resist to higher levels of antibiotics and reduce their efficacy. It is thus necessary to develop strategies targeted to bacterial biofilm infections. Read More

Methicillin-resistant staphylococci are now recognized as a major cause of infectious diseases, particularly in hospitals. Molecular epidemiology is important for prevention and control of infection, but little information is available regarding staphylococcal infections in Northern Thailand. In the present study, we examined antimicrobial susceptibility patterns, detection of antimicrobial resistance genes, and SCC types of methicillin-resistant (MRSA) and methicillin-resistant coagulase-negative staphylococci (MR-CoNS) isolated from patients in a hospital in Northern Thailand.
