Bacillus cereus, best known for causing mild food poisoning, has been recognized as a cause of life-threatening infection in the immunocompromised host.1 It most commonly presents in a neutropenic patient as a single vesicle, pustule, or bulla on a digit or extremities with rapidly spreading cellulitis during the spring and summer.2,3 The bulla may ...

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 ...
