Pili in Gram - positive pathogens
| Most bacterial pathogens have long filamentous structures known as pili or fimbriae extending from their surface. These structures are often involved in the initial adhesion of the bacteria to host tissues during colonization. In Gram-negative bacteria, pili are typically formed by non-covalent interactions between pilin subunits. By contrast, the recently discovered pili in Gram-positive pat...
متن کاملAntibiotic Resistance, Part 1: Gram-positive Pathogens
The Jo 70 ABSTRACT Antibiotics have been instrumental in reducing mortality and morbidity associated with bacterial infections. However, antibiotic resistance has been increasing at an alarming rate due to overuse and inappropriate utilization. The emergence of resistance in Streptococcus pneumoniae, Staphylococcus aureus and enterococci is of concern. The increasing incidence of resistance in ...
متن کاملThe post-antibiotic effects of linezolid against Gram-positive pathogens.
OBJECTIVE To investigate the post-antibiotic effect (PAE) of linezolid against methicillin-resistant and -susceptible staphylococci, vancomycin-resistant and -susceptible enterococci. METHODS Clinical strains of Staphylococcus aureus (S. aureus), Staphylococcus epidermidis (S. epidermidis) and Enterococcus faecalis (E. faecalis) were isolated from hospitalized patients at Ege University Medic...
متن کاملMechanisms of action of newer antibiotics for Gram-positive pathogens.
Certain Gram-positive bacteria, including meticillin-resistant Staphylococcus aureus, vancomycin-resistant enterococci, and quinolone-resistant Streptococcus pneumoniae have achieved the status of "superbugs", in that there are few or no antibiotics available for therapy against these pathogens. Only a few classes of novel antibiotics have been introduced in the past 40 years, and all since 199...
متن کاملNew antimicrobial peptide active against Gram-positive pathogens.
BACKGROUND & OBJECTIVES Human and animal cystatins have been shown to inhibit the replication of certain viruses and bacteria, though it is not directly demonstrated that the effects are due to protease inhibitory capacity of the cystatins. We report antibacterial properties of a novel antimicrobial peptidyl derivative, (2S)-2-(N(alpha)-benzyloxycarbonyl-arginyl-leucylamido)-1-[(E)-cinnamoylami...
