One postulate is that febrile conditions result in the sequestration of soluble iron, effectively starving some pathogens of that essential nutrient. On the basis of our recent experiments, we propose a new mechanism for how fever serves to restrict a wide range of Gram-negative bacteria. The elevated temperature prevents the bacteria from ... The gram-negative bacteria have a characteristic cell envelope that differentiates it from the Gram-positive bacteria. They have a periplasmic space (Periplasm) which separated the outer membrane from the cytoplasmic layer. The periplasmic space has a network of peptidoglycan chains known as the peptidoglycan layer.Gram negative coccobacillus bacteria have bacterial shapes that are in between spherical and rod shaped.
