Gram-positive bacteria are a major group of bacteria distinguished by the structure of their cell wall, which contains a thick layer of peptidoglycan that retains the violet stain used in the Gram staining procedure, causing the cells to appear purple under the microscope. This contrasts with Gram-negative bacteria, which have a thinner peptidoglycan layer and an additional outer membrane. The thick peptidoglycan wall, along with features such as teichoic acids, influences how these organisms interact with their environment, resist certain stresses, and respond to antibiotics. Gram-positive bacteria include many ecologically and medically important genera, ranging from beneficial species used in food production and as part of normal microbiota to significant pathogens responsible for human and animal infections. Their cell-wall characteristics make them targets for particular classes of antibiotics, though resistance is an ongoing concern. Within the scope of Parasite Research, this collection includes related microbiological work, including studies of antimicrobial resistance, molecular identification of staphylococci, the response of oral bacteria to ultrasonication, and plant extracts for antibacterial activity. The page gathers peer-reviewed, open-access research relevant to bacterial biology, identification, and antimicrobial activity across host and environmental settings.
