This Concept Map, created with IHMC CmapTools, has information related to: Answers_Path_Quorum, Once P. aeruginosa is able to replicate and achieve a high population density, quorum sensing leads to activation virulence genes coding for exoenzyme, toxins, and formation of a biofilm. biofilm Live in close association and communicate with other bacteria in the biofilm, Once P. aeruginosa is able to replicate and achieve a high population density, quorum sensing leads to activation virulence genes coding for exoenzyme, toxins, and formation of a biofilm. biofilm Resist attack by antibiotics, The production, release, and community-wide sensing of molecules called autoinducers that modulate gene expression in response to the density of a bacterial population function in virulence Bacterial virulence is largely based on the bacterium's ability to produce gene products called virulence factors that enable that bacterium to colonize the host, resist body defenses, and harm the body., Whether or not a person actually contracts an infectious disease after exposure to a particular potentially pathogenic bacterium depends on several factors. factors important in contracting an infection The number of bacteria that enter the body, Once P. aeruginosa is able to replicate and achieve a high population density, quorum sensing leads to activation virulence genes coding for exoenzyme, toxins, and formation of a biofilm. biofilm Adhere to environmental surfaces and resist flushing, type 3 secretion system function Enables the bacterium to directly inject bacterial effector molecules into the cytoplasm of the host cell in order to alter its cellular machinery or cellular communication., Pathogenicity and virulence are terms that refer to an organism's ability to cause disease. virulence Differences in disease-causing capability between strains of the same microbial species., To cause disease, an organism must first colonize and then harm the host. virulence factors that harm the host The ability to induce autoimmune responses, Once P. aeruginosa is able to replicate and achieve a high population density, quorum sensing leads to activation virulence genes coding for exoenzyme, toxins, and formation of a biofilm. enzymes/toxins Enables the bacteria to get nutrients from damaged host cells., To cause disease, an organism must first colonize and then harm the host. Virulence factors that promote bacterial colonization of the host The ability to evade adaptive immune defenses, Bacterial virulence is largely based on the bacterium's ability to produce gene products called virulence factors that enable that bacterium to colonize the host, resist body defenses, and harm the body. role of quorum sensing When a critical level of autoinducer is reached, the entire population of bacteria is able to simultaneously activate the transcription of their quorum-sensing genes and the body's immune systems are much less likely to have enough time to counter those virulence factors before harm is done., Whether or not a person actually contracts an infectious disease after exposure to a particular potentially pathogenic bacterium depends on several factors. factors important in contracting an infection The quality of the person's innate and adaptive immune defenses, To cause disease, an organism must first colonize and then harm the host. virulence factors that harm the host type 3 secretion system, Pathogenicity and virulence are terms that refer to an organism's ability to cause disease. pathogenicity Differences in disease-causing capability between microbial species., To cause disease, an organism must first colonize and then harm the host. Virulence factors that promote bacterial colonization of the host The ability to compete for iron and other nutrients, To cause disease, an organism must first colonize and then harm the host. Virulence factors that promote bacterial colonization of the host The ability to adhere to host cells and resist physical removal, To cause disease, an organism must first colonize and then harm the host. bacteria functioning as a population Quorum Sensing, Autoinducer/receptor complexes are able to bind to DNA promoters and activate the transcription of quorum sensing-controlled genes. benefit Individual bacteria within a group are able to benefit from the activity of the entire group., To cause disease, an organism must first colonize and then harm the host. Virulence factors that promote bacterial colonization of the host The ability to resist innate immune defenses, Quorum Sensing definition The production, release, and community-wide sensing of molecules called autoinducers that modulate gene expression in response to the density of a bacterial population
