Introduction Pseudomonas aeruginosa is a Gram-negative bacterium that is widely distributed in nature and is known for its versatility and adaptability. It is an opportunistic pathogen capable of causing infections in humans, particularly in individuals with weakened immune systems or underlying medical conditions. P. aeruginosa …
Introduction Quorum sensing (QS) is a sophisticated cell-to-cell communication system used by bacteria to coordinate group behaviors based on the population density. It enables bacterial cells to communicate and synchronize their activities by detecting and responding to small signaling molecules called autoinducers. In quorum sensing, …
Introduction Acinetobacter is a genus of Gram-negative bacteria that are commonly found in the environment, including soil, water, and healthcare settings. While some species of Acinetobacter are harmless and part of the normal flora on human skin, others can cause opportunistic infections, particularly in healthcare-associated …
Introduction Burkholderia cepacia is a species of gram-negative bacteria within the Burkholderia genus. It is a versatile and opportunistic pathogen that can cause infections in both immunocompromised and healthy individuals. B. cepacia is a significant concern, particularly in individuals with cystic fibrosis (CF) and other …
Introduction Streptococcus oralis is a gram-positive bacterium that belongs to the genus Streptococcus. It is a commensal bacterium that commonly inhabits the human oral cavity, along with other oral streptococci. S. oralis is considered a part of the normal oral microbiota and can be found …
