The pneumococcus Streptococcus pneumoniae commonly grows in pairs (diplococci) but also can grow in short chains. An outer polysaccharide capsule protects the organism against phagocytosis, and pneumococcal virulence is related to the composition and size of the capsule (1). There are 90 known capsular types.

Gram-Positive Bacteria: Possible Photosynthetic Ancestry
Science, 1985A 16 S ribosomal RNA gene has been sequenced from Heliobacterium chlorum , the recently discovered photosynthetic bacterium that contains a novel form of chlorophyll. Comparisons with other 16 S ribosomal RNA sequences show that the organism belongs to the Gram ...

Peptide conversations in Gram-positive bacteria
Critical Reviews in Microbiology, 2014Within Gram-positive bacteria, the expression of target genes is controlled at the population level via signaling peptides, also known as pheromones. Pheromones control a wide range of functions, including competence, virulence, and others that remain unknown.

Innate sensors for Gram-positive bacteria
Current Opinion in Immunology, 2003More than half of invasive bacterial infections are Gram-positive in origin. This class of bacteria has neither endotoxins nor an outer membrane, yet it generates some of the most powerful inflammatory responses known in medicine. Some recent seminal studies go a long way toward settling the controversies that surround the process by which Gram ...

Membrane transitions in Gram-positive bacteria
Biochimica et Biophysica Acta (BBA) - Biomembranes, 1971Abstract Intact cells, membranes, and aqueous dispersion of lipids of Micrococcus lysodeikticus undergo a reversible thermotropic transition detectable by differential scanning calorimetry. The phenomenon is suggested to be a “melt” of fatty acid chains within lipid bilayers.

Antimicrobial Resistance in Gram-Positive Bacteria
The American Journal of Medicine, 2006Gram-positive bacteria are common causes of bloodstream and other infections in hospitalized patients in the United States, and the percentage of nosocomial bloodstream infections caused by antibiotic-resistant gram-positive bacteria is increasing. Methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant enterococci (VRE) are of ...

New agents for Gram-positive bacteria
Current Opinion in Microbiology, 2000Infections caused by multiple-resistant Gram-positive organisms continue to occur at an alarming rate worldwide. Two new and unique antimicrobial agents targeted specifically against such organisms, quinupristin/dalfopristin and linezolid, have been approved for use in the USA in the past year and will play an important role in the treatment of life ...

Surface Display on Gram Positive Bacteria
Combinatorial Chemistry & High Throughput Screening, 2012Heterologous surface display on Gram-positive bacteria was first described almost a decade ago and has since then developed into an active research area. Gram-positive bacterial surface display has today found a range of applications, in immunology, microbiology and biotechnology. Live bacterial vaccine delivery vehicles are being developed through the

Pilus Assembly in Gram-Positive Bacteria
2015Pili of Gram-positive bacteria are unique structures on the bacterial surface, assembled from covalently linked polypeptide subunits. Pilus assembly proceeds by transpeptidation reactions catalyzed by sortases, followed by covalent anchoring of the filament in the peptidoglycan layer.

Vaginal Immunization with Recombinant Gram‐Positive Bacteria
American Journal of Reproductive Immunology, 1998PROBLEM: Many viral and bacterial pathogens enter the body through the genital mucosa. Therefore, one of the major goals of a vaccine against sexually transmitted diseases (STDs) should be to induce an immune response in the genital mucosa capable of controlling the entry of the pathogen.
