Karten in diesem Stapel (20)
- 1What are the pigment-producing bacteria?Actinomyces israelii; S aureus; P aeruginosa; Serratia marcescens
- 2Describe the pigment of the following pigment-producing bacteria. Actinomyces israeliiYellow "sulfur" granules which are composed of filaments of bacteria
Israel has yellow sand. - 3Describe the pigment of the following pigment-producing bacteria. S aureusYellow pigment
Aureus (Latin) = Gold - 4Describe the pigment of the following pigment-producing bacteria. P aerugiosaBlue-green pigment (pyocyanin and pyoverdin).
Aerugula is green. - 5Describe the pigment of the following pigment-producing bacteria. Serratia marcescentsRed
Think red maraschino cherries. - 6What are in vivo biofilm producing bacteria?S epidermidis, Viridans streptococci (S mutans, S sanguinis), P aeruginosa, Nontypeable (unencapsulated) H influenzae
- 7Biofilm from S epidermidis is associated with what?Catheter and prosthetic device infections
- 8Biofilm from Viridans streptococci (S mutans, S sanguinis) is associated with what?Dental plaques, infective endocarditis
- 9Biofilm from P aeruginosa is associated with what?Respiratory tree colonization in patients with cystic fibrosis, ventilator-associated pneumonia. Contact lens-associated keratitis.
- 10Biofilm from Nontypeable (unencapsulated) H influenzae is associated with what?Otitis media
- 11Bacterial Virulence Factors promote what?Evasion of host immune response.
- 12What are Bacterial Virulence Factors?Protein A, IgA protease, and M protein
- 13Bacterial Virulence Factors What does Protein A do?Binds Fc region of IgG. Prevents opsonization and phagocytosis. Expressed by S aureus.
- 14Bacterial Virulence Factors What does IgA protease do?Enzyme that cleaves IgA, allowing bacteria to adhere to and colonize mucous membranes. Secreted by S pneumoniae, H influenzae, type B, and Neisseria
- 15acterial Virulence Factors What does M protein do?Helps prevent phagocytosis. Expressed by group A streptococci. Shares similar epitopes to human cellular proteins (molecular mimicry); possibly underlines the autoimmune response seen in acute rheumatic fever.
- 16Describe Type III secretion systemAlso known as "injectisome." Needle-like protein appendage facilitation direct delivery of toxins from certain gram- bacteria (eg Pseudomonas, Salmonella, Shigella, E coli) to eukaryotic host cell.
- 17Which bacterial virulence factor is expressed by S aureus?Protein A
- 18Which bacterial virulence factor is secreted by S pneumoniae, H influenzae, type B, and Neisseria?IgA protease
- 19Which bacterial virulence factor is expressed by group A streptococci?M protein
- 20Which bacterial virulence factor shares similar epitopes to human cellular proteins (molecular mimicry)?M protein
