biology and examples of bacteria Flashcards
veiberio choleria
glycine modification of lipid a, hide form host
helicobacter polyeri
diacylation of lipid a- tlr4
tectonic acids modiifaction
glycosylation-
d-alinine modification
glycolsiadtion
immune system resistance suseptable to bacteriaphages
d-alianine
increased resistance to host defence poor adhesion
cross brideds of glycoside causes the tectonic acids to be covalently bound by by what enzyme?
sortage enzyme ( stamlococcus euranus)
tectonic acids help with what bacteria to do what
stamplycocci uenaous to atteactch to coloigen
listeria monocles had what test done on it?
srta - lack of sortase a enzyme
what is the capsule made out of?
glycocalyx (sticky sugar
coat)
bacillus anthrax-
capsulated cuses infection
Streptococcus pneumoniae
only encapsulated causes pnemonia
capsule inhibits acces to what
opisons c3b - C3b is often referred to as an opsonin because it tags pathogens
Pseudomonas aeruginosa
Extracellular polysaccharides- pel psl and agriginate
p Agnrenosa has 3 differnt types of eps modifications what are they?
FRD1- loose
PAO1-Tight scaffold
PA14- fabric like matric
S. aureus and S. epidermidis cause what
cause
biomedical device related infections
what are the Surface layers (S-layers)
they are like chainmail, * Composed of protein or glycoprotein- porous mesh - oblique, square or hexagonal
Structure of fimbriae in E. coli-
FImH tip protein- helical rod of fiMA- Adherence to uroepithelial cells of the bladder.
Receptor = mannose-containing glycoproteins
what is the pilis example?
Pilus example: Type IV pili in P. aeruginosa
what then knows the twithing ability of p.agninosa?
esculentin-1a: novel AMP that targets type IV twitching
motility- novel antimicrobial peptide-orinanally identified in frogs
