Adhesins - Study guides, Class notes & Summaries

fimbriae/pili, afimbrial adhesins correct answers mechanisms of adhesion to host surfaces adhesins at tip that bind to specific glycoproteins/glycolipids on host cell membranes, long major filament that can extend beyond the capsule correct answers main features of pili/fimbriae molecules embedded in bacterial membranes, bind to glycoproteins or glycolipids on host membranes or can bind ECM such as fibronectin correct answers main features of afimbrial adhesins tracheal colonization fac...

What is the difference between a fimbrial adhesin and a non-fimbrial adhesin? correct answers Fimbrial adhesins are located at a scaffold-like structure (pilus or fibria) while afribrial adhesins are anchored directly in bacterial membrane. The E. coli P pilus is attached to the outer membrane and consists of several proteins. What is the role of the PapH protein? correct answers PapH is the anchor subunit in the outer membrane; it anchors the major pilus subunit to the outer membrane What...

Bacterial Colonization Q&A fimbriae/pili, afimbrial adhesins - mechanisms of adhesion to host surfaces adhesins at tip that bind to specific glycoproteins/glycolipids on host cell membranes, long major filament that can extend beyond the capsule - main features of pili/fimbriae molecules embedded in bacterial membranes, bind to glycoproteins or glycolipids on host membranes or can bind ECM such as fibronectin - main features of afimbrial adhesins tracheal colonization factor (fimbrial...

Infection correct answers colonization of the body by a microorganism Disease correct answers any change from the general state of good health; not all disease is due to infection and infection does not always cause disease Sign correct answers Objective evidence of disease (rash, fever) Symptom correct answers Subjective evidence of disease (pain, headache) Mutualism correct answers benefits both organisms Commensalism correct answers One population benefits, the other is neither...

pathogenicity Ans: ability to cause disease by overcoming the defenses of a host virulence Ans: degree or extent of pathogenicity portals of entry Ans: avenues through which pathogens gain entrance into a host, through skin, mucous membranes, or parenterally ID50 Ans: virulence of a microbe, infectious dose for 50% of a sample pop. LD50 Ans: potency of a toxin, lethal dose for 50% of a sample pop. 2 adherence (adhesion) Ans: attachment between pathogen and host adhesins/ligands A...

MIP 300 Exam 2: Questions and answers, rated A+ There are many factors that affect the outcome of a host microbe interaction (disease or lack of disease development). Please describe at least 3 factors that help determine whether a microbe will cause a disease in a particular host. - -1. ability to adhere to and colonize host - adhesins help adhere to surfaces: fimbriae/pili, capsule/glycocalyx/slime layer, S-layer, techoic acid, viral capsids & envelopes. 2. ability to grow in or on...
