    Abstract: This third edition volume expands on the previous editions with an update on the latest techniques used for the detection, genotyping, and investigating pathogenesis of Staphylococcus aureus in vitro and in vivo. The methods covered in this book mostly focus on routine clinical diagnosis, surveillance, research, and practice for treatment of patients infected by multi-drug resistant S. aureus. The book also covers the epidemiology of MRSA, molecular typing approaches, clinical treatment of MRSA infections, and animal models of drug discovery. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Informative and cutting-edge, Methicillin-Resistant Staphylococcus Aureus (MRSA) Protocols: Cutting-Edge Technologies and Advancements, Third Edition is a valuable resource for researchers looking to set up new methods to study S. aureus, and will also be very useful for technicians and scientists working on other bacterial pathogens

    Notes: The emergence of multi-drug resistant bacterial pathogens is generating enormous public health concern, and highlights an urgent need for new, alternative agents for treating multi-drug-resistant pathogens. The gene products essential for bacterial growth in vitro and survival during infection constitute an initial set of protein targets for the development of antibacterial agents. In this study, we employed regulated gene expression approaches and demonstrated that a putative glycoprotease (Gcp) is required for staphylococcal growth in the culture. We found that Staphylococcus aureus becomes more sensitive to the Zn2+ ion under the downregulation of Gcp expression in vitro. Bioinformatic analyses demonstrated that Gcp is conserved in many Gram-positive pathogens and exists in a variety of Gram-negative pathogens. Our results indicate that Gcp is a potential novel target for the development of antimicrobials against S. aureus infection.

    Notes: Validation of antibiotic mode of action in whole bacterial cells is a key step for antibiotic drug discovery. In this study, one potential drug target, enoyl-acyl carrier protein reductase (FabI), an essential enzyme in the fatty acid biosynthesis pathway, was used to evaluate the feasibility of using a regulated antisense RNA interference approach to determine antibiotic mode of action. Antisense isogenic strains expressing antisense RNA to fabI were created using a tetracycline-regulated vector in Staphylococcus aureus. We demonstrated that down-regulation of FabI expression by induction of fabI antisense RNA induces a conditional lethal phenotype. In contrast, partial down-regulation gives a viable cell with a significant increase in sensitivity to FabI-specific inhibitors (i.e., a sensitized phenotype). More importantly, the mode of action for novel FabI inhibitors has been confirmed using this genetic approach in whole cell assay. These results indicate that controlled antisense technology provides a robust tool for defining and tracking the mode of action of novel antibacterial agents.
